The management terminal 40 may have a touch panel instead of the input unit 44 and the management display unit 45, or together with at least one of them.

[0023] The management processing unit 42 causes the registration status viewing page Pj and the production management record page Pk, which will be described later, to be displayed on the management display unit 45 in cooperation with the paddy field management device 10 in response to operation signals from the input unit 44 and the like. The management processing unit 42 accepts operations of the user using each page and executes processing according to the operation content. The management processing unit 42 is composed of one or more processors. More specifically, the management processing unit 42 is composed of an arithmetic processing device such as a CPU, MPU, or GPU, and various functions of the management processing unit 42 are realized by the arithmetic processing device and an operation program. Some of the various functions of the management processing unit 42 may be realized by hardware.

[0024] The paddy field management device 10 includes a communication unit 11, a control unit 12, and a storage unit 13. The communication unit 11 is an interface for the control unit 12 to communicate with external devices such as the operation terminal 20, the information terminal 30, and the management terminal 40 by wire or wirelessly. The storage unit 13 is composed of a RAM, a ROM, a flash memory, an eMMC, an SSD, an HDD, or the like. In the storage unit 13, in addition to the operation program of the control unit 12 including the paddy field management program 13p, various information is stored. The paddy field management program 13p is software that realizes various functions in cooperation with an arithmetic processing device such as a CPU, MPU, or GPU.

[0025] In the storage unit 13, information for causing each page, which will be described later, to be displayed and function is stored. The storage unit 13 includes a user database (user DB) in which information about the user is organized. For example, the user DB is configured by associating the user name and the identification information of the user with information about one or more paddy fields managed by the user. These information are input at the time of introduction of this system and can be updated as appropriate according to changes in the situation of the paddy field or changes of the user.

[0026] The storage unit 13 includes a paddy field database (paddy field DB) 13d in which information about paddy fields is organized. In the paddy field database 13d, for example, information such as the name of the paddy field, unique identification information of the paddy field, Kochi number, cultivated area, yield grade, variety of rice to be cultivated, memo, information related to a photo representing the panorama of the paddy field, information of a registration image (mid-drying registration image) related to the start and end of mid-drying, location information, etc. is managed. The mid-drying registration image is composed of a start image S indicating the start of mid-drying and an end image E indicating the end of mid-drying. The storage unit 13 may have a storage 13s for storing the mid-drying registration image.

[0027] The control unit 12 is composed of one or more processors. More specifically, the control unit 12 is composed of an arithmetic processing device such as a CPU, MPU, or GPU, and various functions of the control unit 12 are realized by the arithmetic processing device and the paddy field management program 13p. A part of various functions of the control unit 12 may be realized by hardware. The paddy field management program 13p functions a computer (one or more processors) as recording processing means 12a and management processing means 12b.

[0028] The control unit 12 provides various information in response to a user's request via the information terminal 30. The control unit 12 causes the storage unit 13 to store the information instructed to be registered by the user via the information terminal 30. The control unit 12 executes the creation and update of various databases in the storage unit 13. The control unit 12 causes the display unit 35 to display a start registration page Ps for receiving the registration of the start image S indicating the start of mid-drying in response to an instruction to display a registration page for starting mid-drying of the paddy field. Further, the control unit 12 causes the display unit 35 to display an end registration page Pe for receiving the registration of the end image E indicating the end of mid-drying in response to an instruction to display a registration page for ending mid-drying of the paddy field.

[0029] The start registration page Ps of this embodiment is configured to accept the registration of a first start image S1 and a second start image S2 as start images S. The first start image S1 is an image indicating a state where water intake into the paddy field is impossible. The second start image S2 is an image indicating a state where water in the paddy field is being drained. Hereinafter, when referring to the first start image S1 and the second start image S2 without distinction, they may be collectively referred to as the start image S.

[0030] The end registration page Pe of this embodiment is configured to accept the registration of a first end image E1 and a second end image E2 as end images E. The first end image E1 is an image indicating a state where water intake into the paddy field is possible. The second end image E2 is an image indicating a state where water drainage in the paddy field is impossible. Hereinafter, when referring to the first end image E1 and the second end image E2 without distinction, they may be collectively referred to as the end image E.

[0031] That is, upon receiving an instruction to display a registration page for starting mid - drying of the paddy field, the control unit 12 causes the display unit 35 to display the start registration page Ps that accepts the registration of the first start image S1 and the second start image S2. Also, upon receiving an instruction to display a registration page for ending mid - drying of the paddy field, the control unit 12 causes the display unit 35 to display the end registration page Pe that accepts the registration of the first end image E1 and the second end image E2.

[0032] Here, with reference to FIGS. 2 and 3, the relationship between the state of the paddy field and the states of the water intake and drainage ports at the start and end of mid - drying will be described. FIG. 2 is a schematic diagram illustrating the paddy field at the start of mid - drying and the states of the water intake and drainage ports of the paddy field. FIG. 3 is a schematic diagram illustrating the paddy field at the end of mid - drying and the states of the water intake and drainage ports of the paddy field. In each figure, ○ indicates a state where water passes through, such as an open state, and × indicates a state where water does not pass through, such as a closed state.

[0033] More specifically, the closed state of the water intake means a state where it is impossible to take in water into the paddy field, corresponding to a state closed by a dedicated lid, sandbags, etc., or a state where the intake pipe has been removed. The open state of the water intake means a state where it is possible to take in water into the paddy field, corresponding to a state where a dedicated lid, sandbags, etc. have been removed, or a state where the intake pipe has been set. The closed state of the drain means a state where it is impossible to discharge the water in the paddy field, corresponding to a state closed by a dedicated lid, sandbags, etc. The open state of the drain means a state where the water in the paddy field is discharged, corresponding to a state where a dedicated lid, sandbags, etc. have been removed.

[0034] As shown in FIG. 2, when the water intake is in the closed state and the drain is in the open state, water does not flow in from the water intake, and the water accumulated in the paddy field continues to be discharged from the drain, and finally the water in the paddy field drains out. Therefore, if a photo of the area around the water intake such as region R1 is recorded as the first start image S1 and a photo of the area around the drain such as region R2 is registered as the second start image S2 with the water intake in the closed state and the drain in the open state, these will serve as evidence indicating the start of mid-drying.

[0035] On the other hand, when, as shown in FIG. 3, the water intake is in the open state and the drain is in the closed state starting from the state shown in FIG. 2, since the water flowing in from the water intake is not discharged from the drain, water accumulates in the paddy field. However, at the timing just after switching from the state shown in FIG. 2 to the state shown in FIG. 3, there is no water accumulated in the paddy field. Therefore, after the planned mid-drying period has elapsed, if a photo of the area around the water intake such as region R1 is recorded as the first end image E1 and a photo of the area around the drain such as region R2 is registered as the second end image E2 with the water intake in the open state and the drain in the closed state, these will serve as evidence indicating the end of mid-drying, specifically, evidence indicating that the mid-drying period has been extended by a predetermined number of days.

[0036] The control unit 12 includes a recording processing means 12a and a management processing means 12b. The recording processing means 12a performs processing related to the first service and manages the information provided to the user via the information terminal 30. By providing various information to the information terminal 30, the recording processing means 12a causes various pages to be displayed on the display unit 35. Here, a page basically refers to a web page.

[0037] More specifically, the recording processing means 12a causes a paddy field list page Pa, a paddy field information page Pb, a work selection page Pc, a start registration page Ps, a registration completion page Pm, an end registration page Pe, and a registration completion page Pn, which will be described later, and sub-windows related thereto, to be displayed on the display unit 35 of the information terminal 30. The recording processing means 12a causes these pages to function in cooperation with the information terminal 30. The recording processing means 12a stores the information instructed to be registered via these pages in the storage unit 13. The control unit 12 stores the start image S instructed to be registered via the start registration page Ps and the end image E instructed to be registered via the end registration page Pe in the storage unit 13.

[0038] The management processing means 12b performs processing related to the second service and, in this embodiment, manages the information provided to the user via the management terminal 40. The management processing means 12b causes a registration status browsing page Pj and a production management record page Pk, which will be described later, to be displayed and function on the management display unit 45 in cooperation with the management terminal 40. When information regarding the mid-season drying of a paddy field is requested via the management terminal 40, the management processing means 12b causes the production management record page Pk to be displayed on the management display unit 45. The production management record page Pk includes the start image S and the end image E together with the mid-season drying period data Q, which is information regarding the mid-season drying start date and mid-season drying end date of the paddy field selected by the user. However, the management processing means 12b may cause the registration status browsing page Pj and the production management record page Pk to be displayed and function on the display unit 35 in cooperation with the information terminal 30. In this case, when information regarding the mid-season drying of a paddy field is requested via the information terminal 30, the management processing means 12b causes the production management record page Pk to be displayed on the display unit 35.

[0039] Referring to FIGS. 4 to 17, these transitions will be described together with the configuration of each page displayed at the start of the trunk. The paddy field list page Pa illustrated in FIG. 4 has an application part A, a page part n, a user part Y, and a title part T. In the application part A, for example, the name of this system (this application) and the like are written. In the page part n, for example, terms related to the page being displayed are written. In the user part Y, for example, the name of the logged-in user, or a text including the user name, etc. are written. In the title part T, for example, the title of the page is written. Since none of the application part A, the page part n, the user part Y, and the title part T are essential components, they can be appropriately selected and discarded, and the characters to be written can also be changed as appropriate. However, in order to grasp the general framework of the page being displayed, it is better to have at least one of the page part n and the title part T, and in order to confirm the logged-in user, it is better to have the user part Y.

[0040] Also, the paddy field list page Pa has a list display part 50 and a filtering button 58. In the list display part 50, one or more paddy field parts 5n are displayed. The paddy field part 5n is a thing in which information related to the paddy field is extracted and written. Hereinafter, the information related to the paddy field is also referred to as "paddy field data". That is, when a plurality of paddy fields are registered in this system, in the list display part 50, as shown in FIG. 4, the paddy field parts 5n are displayed in a list for each paddy field. In each paddy field part 5n, various information extracted from the corresponding paddy field data is organized and displayed. The paddy field part 5n preferably includes at least a paddy field name indicating the name or abbreviation of the paddy field. The paddy field part 5n illustrated in FIG. 4 further includes information on the cultivated area, the variety of rice being cultivated, and the memo writing. However, the information written in the paddy field part 5n is not limited to these and can be appropriately selected and discarded.

[0041] The filtering button 58 is a virtual button for instructing the filtering of the paddy field section 5n to be displayed on the list display section 50. When the user presses the filtering button 58 by an operation such as tapping or clicking, a filtering screen (not shown) for instructing filtering according to the condition settings is displayed. The filtering screen may be displayed as a sub-window or may be a web page transitioned from the paddy field list page Pa. When the user sets the filtering conditions on the filtering screen and instructs filtering, the paddy field section 5n corresponding to the paddy fields that meet the set conditions is displayed in the list display section 50 of the paddy field list page Pa.

[0042] The paddy field section 5n of the present embodiment is configured to be selectable itself, that is, it functions as a virtual button that accepts the user's selection operation. However, the paddy field section 5n may be configured to be selected through a selection section such as a checkbox or a radio button arranged in association therewith. The paddy field list page Pa may be configured to be able to sort and search the order of the paddy field sections 5n in the list display section 50.

[0043] By the way, in FIG. 4, the page section n and the title section T are marked as the field list, which shows that this system can be widely applied not only to paddy fields but also to places where agricultural crops such as fields, orchards, and pastures are cultivated. However, since the present embodiment is an example of the case where this system manages paddy fields, characters such as a paddy field list may be marked in the page section n and the title section T, or other notations may be used. When applying this system to other than paddy fields, the content of the work selection page Pc in FIG. 6 and the like will be different.

[0044] The paddy field information page Pb illustrated in FIG. 5 has a detailed section 51, an edit button 52, a map button 53, a work date registration button 54, a history confirmation button 55, a list transition button R, and a back button r. The detailed section 51 is a part where the paddy field data of the paddy field associated with the paddy field section 5n selected on the paddy field list page Pa is described in more detail. The detailed section 51 illustrated in FIG. 5 includes a photograph showing the appearance of the paddy field registered in advance. Such a configuration helps in cases where it is difficult to make a judgment based only on the paddy field name H, etc.

[0045] The edit button 52 is a virtual button for editing the pre-registered paddy field data. When the user presses the edit button 52, an edit screen (not shown) for editing the paddy field data is displayed. The edit screen may be displayed in a sub-window or may be a web page transitioned from the paddy field information page Pb. When the user edits (changes, modifies, deletes, etc.) the information included in the paddy field data on the edit screen, the edited content is reflected in the paddy field section 5n and the detailed section 51.

[0046] The map button 53 is a virtual button for displaying a map screen (not shown) showing the location of the paddy field associated with the detailed section 51. The map screen may be pre-registered by the user or may be displayed in cooperation with various map search services. The work date registration button 54 is a virtual button for transitioning to the work selection page Pc. The history confirmation button 55 is a virtual button for displaying a history screen (not shown) for confirming the display history and edit history. The list transition button R is a virtual button for transitioning to the paddy field list page Pa. The back button r is a virtual button for returning to the previous display state or the previous display page. In FIG. 5, an example is shown where the edit button 52 and the map button 53 are displayed overlapping the detailed section 51, but it is not limited to this, and either or both of the edit button 52 and the map button 53 may be displayed outside the area of the detailed section 51. The paddy field information page Pb may not have at least one or both of the map button 53 and the history confirmation button 55.

[0047] The work selection page Pc illustrated in FIG. 6 has a plurality of work item buttons. In FIG. 6, as work item buttons, a plowing button 61, a harrowing button 62, a rice transplanting button 63, a mid-stem start button 64, and a mid-stem end button 65 are shown in the work selection page Pc as an example. The types of work item buttons are not limited to these, and the work selection page Pc only needs to include at least the mid-stem start button 64 and the mid-stem end button 65. The mid-stem start button 64 is a virtual button for instructing the display of a registration page for the start of the mid-stem in a paddy field. In the present embodiment, the registration page for the start of the mid-stem in a paddy field corresponds to the start registration page Ps. The mid-stem end button 65 is a virtual button for instructing the display of a page related to the end of the mid-stem. In the present embodiment, the page related to the end of the mid-stem corresponds to the end registration page Pe.

[0048] FIGS. 7, 8, 10 to 12 illustrate the start registration page Ps related to the registration process of the first start image S1. The start registration page Ps illustrated in FIG. 7 has a work section W, a date setting section 70s, a first button 71, a second button 72, an attachment section 73, a registration button 76, and a cancel button 77. In the work section W, the work name associated with the start registration page Ps is written. The date setting section 70s is for setting the start date of the mid-stem. In the present embodiment, when the user presses the date setting section 70s, it is configured to switch to a date selection mode as shown in FIG. 8. However, the date selection via the date setting section 70s is not limited to the drum roll method as shown in FIG. 8, and various methods such as selecting a date from a calendar display can be adopted. However, the date setting section 70s may be configured to allow direct input of the date.

[0049] The first button 71 is a virtual button for enabling the registration of the first start image S1 or the first end image E1. The second button 72 is a virtual button for enabling the registration of the second start image S2 or the second end image E2. The pasting part 73 is a location where the photographed or selected photo is displayed. In the present embodiment, the pasting part 73 functions as a virtual button that displays a selection screen (not shown) that requires a choice between photo shooting and photo selection, with the central character part or the whole.

[0050] When photo shooting is selected by the user, the information terminal 30 switches to an imaging screen Gm as shown in FIG. 9. The imaging screen Gm includes at least a monitor part M that displays the image captured by the imaging part 36. Whether the imaging screen Gm has other virtual buttons such as a shooting button B depends on the type of browser, the model of the information terminal 30, etc. When photo selection is selected by the user, the information terminal 30 or a server etc. in cooperation with this becomes in a state where photos stored therein can be selected, and that state depends on the type of browser, the model of the information terminal 30, etc.

[0051] The start registration page Ps may be configured as shown in FIG. 10 so that photo shooting and photo selection can be selected without going through a selection screen (not shown). The start registration page Ps in FIG. 10 has a shooting button 73a for instructing the activation of the imaging part 36 and a selection button 73b for enabling the selection from the photos being saved. Note that the registration button 76 and the cancel button 77 do not function in the states shown in FIGS. 7 and 10.

[0052] FIG. 11 illustrates the start registration page Ps after a photo is taken by the imaging screen Gm as shown in FIG. 9 or one of the saved photos is selected. In the start registration page Ps of FIG. 11, a photo So as a candidate for the first start image S1 is displayed at the pasting portion 73. As shown in FIG. 11, in the start registration page Ps where the taken or selected photo is being displayed, the registration button 76 and the cancel button 77 function. When the user presses the registration button 76, a confirmation screen Gs as shown in FIG. 12 is displayed on the display portion 35, and when the user presses the cancel button 77, it returns to the start registration page Ps in a state where no photo is displayed as shown in FIG. 7.

[0053] The confirmation screen Gs in FIG. 12 includes at least an affirmative button By and a negative button Bn. The affirmative button By is a virtual button for officially registering the photo displayed on the start registration page Ps immediately after shooting or selection, and the negative button Bn is a virtual button for canceling the photo and returning to the start registration page Ps in a state where no photo is displayed as shown in FIG. 7. The confirmation screen Gs illustrated in FIG. 12 has an explanatory notation Sa indicating the content of the photo to be registered here and a caution notation Sb indicating precautions after registration.

[0054] The registration completion page Pm is a page indicating that at least one image related to the mid-stream start has been registered. The registration completion page Pm in FIG. 13 has a status portion 80, a start information portion Ma, a first start portion 81, and a second start portion 82. Information indicating the current status is written in the status portion 80. In FIG. 13, it is written that the photo of the water intake at the time of mid-stream start, that is, the first start image S1, has been registered. A space for displaying the date of mid-stream start (mid-stream start date) is secured in the start information portion Ma, but in this embodiment, the date of mid-stream start is not displayed in the start information portion Ma until both the first start image S1 and the second start image S2 are registered.

[0055] The first start part 81 is the part where the first start image S1 is displayed. The second start part 82 is the part where the second start image S2 is displayed. As shown in FIG. 13, the first start part 81 may include a notation indicating that the displayed photo is the first start image S1 (denoted as "water intake" in FIG. 13). Similarly, the second start part 82 may include a notation indicating that the displayed photo is the second start image S2 (denoted as "drain outlet" in FIG. 13).

[0056] FIGS. 14 to 16 illustrate the start registration page Ps related to the registration process of the second start image S2. The basic configuration of the start registration page Ps in FIG. 14 is the same as that of the start registration page Ps in FIG. 7. However, in the start registration page Ps of FIG. 14, the first button 71 is in a non-functional state. In the example of FIG. 14, the notation of the first button 71 has changed to a character indicating that the first start image S1 has been registered, and the density of the button has also become lighter. The second button 72 may be in a selected state from the beginning.

[0057] FIG. 15 illustrates the start registration page Ps after a photo is taken by the imaging screen Gm as shown in FIG. 9 or one of the saved photos is selected. In the start registration page Ps of FIG. 15, a photo So as a candidate for the second start image S2 is displayed at the sticking part 73. In the start registration page Ps in the state as shown in FIG. 15, similar to the case of FIG. 11, the registration button 76 and the cancel button 77 function. When the user presses the registration button 76, a confirmation screen Gs as shown in FIG. 16 is displayed on the display part 35, and when the user presses the cancel button 77, it returns to the start registration page Ps in a state where no photo is displayed as shown in FIG. 14. The configuration of the confirmation screen Gs in FIG. 16 is the same as the example in FIG. 12, and the description notation Sa is associated with the second start image S2.

[0058] The registration completion page Pm in FIG. 17 has the same configuration as the example in FIG. 13. In the first start section 81, the first start image S1 is displayed, and in the second start section 82, the second start image S2 is displayed. Therefore, in the status section 80, it is marked as "Registered" to indicate that the registration at the start of the intermediate process has been completed. Also, in the start information section Ma, the date of the start of the intermediate process is marked. Note that in FIG. 17, a registration completion page Pm having a scheduled date display Dx indicating the scheduled end date of the intermediate process is exemplified. In the present embodiment, the date of the start of the intermediate process can be set at any time until the registration is completed as shown in FIG. 17, and the setting can also be changed. Specifically, in the start registration page Ps in any of the states shown in FIGS. 7, 10, 11, 14, and 15, the date of the start of the intermediate process can be set and changed.

[0059] Next, with reference to FIGS. 18 to 20, these transitions will be described together with the configuration of each page displayed at the end of the intermediate process. However, since the basic screen transition is the same as that at the start of the intermediate process described with reference to FIGS. 4 to 17, here, in particular, the end registration page Pe in FIG. 18 and the registration completion page Pn in FIG. 19 will be described.

[0060] The end registration page Pe in FIG. 18 has a scheduled date display Dx and a date setting section 70e. In the scheduled date display Dx, the scheduled end date of the intermediate process is displayed (hereinafter also simply referred to as the "scheduled end date"). The scheduled end date is obtained, for example, by adding the reference number of days and the suppression coefficient based on the intermediate process period in the recent several years to the date of the start of the intermediate process. The date setting section 70e is for setting the end date of the intermediate process, and its configuration is the same as that of the date setting section 70s.

[0061] The registration completion page Pn is a page indicating that at least one image related to the end of the intermediate process has been registered. In the registration completion page Pn in FIG. 19, the first end image E1 is displayed in the first end section 83, and the second end image E2 is displayed in the second end section 84. In the end information section Mb, the date of the end of the intermediate process (the end date of the intermediate process) is marked. In the present embodiment, the date of the end of the intermediate process can be set at any time until the registration is completed as shown in FIG. 19, and the setting can also be changed.

[0062] Incidentally, it is also assumed that the user may forget the scheduled end date of the mid-season drainage and extend the mid-season drainage period unexpectedly. This is especially true when the user manages a large number of paddy fields. That is, just displaying the scheduled date display Dx on the end registration page Pe may not be able to avoid the above situation. Therefore, as shown in FIG. 20, on the paddy field list page Pa, the scheduled date display Dx may be displayed in the paddy field section 5n associated with the paddy field in which the mid-season drainage is being carried out. By doing so, the scheduled end date for each paddy field can be confirmed at the initial stage of the screen transition, thus improving convenience.

[0063] The registration status viewing page Pj illustrated in FIG. 21 is a page on which information related to mid-season drainage (hereinafter also referred to as mid-season drainage registration data), which is information related to one or more paddy fields managed by the user using this system (paddy field data), is displayed in a list. The mid-season drainage registration data is information registered by the user using an application related to the first service of this system.

[0064] On the registration status viewing page Pj of FIG. 21, the title section T indicating the title of the page is labeled "Mid-season Drainage Implementation Status", and below that, an explanation regarding the display of production management records is shown. The registration status viewing page Pj has a list display section Z1 and a search section 92. The search section 92 is used when narrowing down the information being displayed in the list display section Z1.

[0065] In the list display section Z1 illustrated in FIG. 21, for each paddy field, the "field", "variety" indicating the variety of rice, mid-drying period, mid-drying start date, "water intake (start time)" corresponding to the first start image S1, "drainage outlet (start time)" corresponding to the second start image S2, mid-drying end date, "water intake (start time)" corresponding to the first end image E1, "drainage outlet (start time)" corresponding to the second end image E2, and "heading date" are organized for each paddy field. These pieces of information are based on the mid-drying registration data, and the information displayed in the list display section Z1 may be a part of these. Also, in the list display section Z1, a display button 93 is associated with each paddy field. The display button 93 is a virtual button for displaying the production management record of the corresponding paddy field.

[0066] The production management record page Pk illustrated in FIG. 22 is displayed when the display button 93 is pressed on the registration status viewing page Pj of FIG. 21. In the title section T, it is indicated that it is a production management record. The production management record page Pk has a paddy field details section Z2 and an image display section Z3. The paddy field details section Z2 displays various information about the paddy field and includes at least the mid-drying period data Q. In the image display section Z3, the start image S and the end image E are displayed. In the example of FIG. 22, the first start image S1, the second start image S2, the first end image E1, and the second end image E2 are displayed in the image display section Z3. Also, in the image display section Z3, photo titles Ta to Td are associated with each of these images to indicate what each image refers to. The production management record page Pk can be utilized as a production management record to be used as reference material at the time of applying for registration under the J-credit system.

[0067] Subsequently, with reference to FIGS. 23 to 27, the paddy field management method according to the present embodiment will be described. First, based on the sequence charts of FIGS. 23 and 24, an operation example at the time of starting registration of mid-drying will be described. Note that since the processing of steps S134 to S146 is the same as the processing of steps S117 to S129, the description of steps S134 to S146 will be omitted or simplified as appropriate.

[0068] When the user launches an application related to the first service of this system and the login process is completed, the control unit 12 of the paddy field management device 10 causes the initial screen to be displayed on the display unit 35. That is, when the control unit 12 acquires a login request from the information terminal 30 through the login screen (step S101), it checks the user's unique information included in the login request against the user database. When the verification is successful (step S102), the control unit 12 transmits paddy field list data to the information terminal 30 (step S103), and causes the display unit 35 to display a paddy field list page Pa as shown in FIG. 4 via the information processing unit 32 of the information terminal 30 (step S104). In this embodiment, the paddy field list page Pa is set as the initial screen. The paddy field list data is information for displaying and functioning the paddy field list page Pa.

[0069] When one paddy field section 5n is selected in the list display unit 50 and the information processing unit 32 receives a paddy field selection operation (step S105), it transmits selection data to the paddy field management device 10. The selection data includes the identification information of the paddy field associated with the selected paddy field section 5n (step S106). The control unit 12 checks the transmitted selection data against the paddy field database 13d, and by transmitting the extracted paddy field data to the information terminal 30 (step S107), causes the display unit 35 to display a paddy field information page Pb as shown in FIG. 5 via the information processing unit 32 (step S108). The paddy field data is information for displaying and functioning the paddy field information page Pb.

[0070] When the work date registration button 54 is pressed and the display of work is instructed, the information processing unit 32 transmits a work display request to the paddy field management device 10 (step S109). In response to the work display request, the control unit 12 transmits work selection data to the information terminal 30 (step S111), and causes the display unit 35 to display a work selection page Pc as shown in FIG. 6 via the information processing unit 32 (step S112). The work selection data is information for displaying and functioning the work selection page Pc.

[0071] When the middle-drainage start button 64 is pressed and the display of the registration page for the start of middle-drainage in the paddy field is instructed (step S113), the information processing unit 32 sends a start registration request to the paddy field management device 10 (step S114). In response to the start registration request, the control unit 12 sends start registration data to the information terminal 30 (step S115), and causes the display unit 35 to display a start registration page Ps as shown in FIG. 7 via the information processing unit 32 (step S116). The start registration data is information for displaying and functioning the start registration page Ps.

[0072] When the date of middle-drainage start is set by an operation on the date setting unit 70s, the information processing unit 32 registers the set date as the middle-drainage start date (step S117). Further, when the first button 71 is pressed by the user while the water intake is not selected, the information processing unit 32 switches to the state where the water intake is selected (step S118). When the user instructs the taking of a photo, the information processing unit 32 activates the imaging unit 36 to display an imaging screen Gm, and when a photo is taken (step S119), it causes the display unit 35 to display a start registration page Ps including an image of the photo corresponding to the water intake as shown in FIG. 11 (step S120). On the other hand, when the user requests the selection of a photo, the information processing unit 32 makes the saved photos selectable, and when a photo is selected (step S119), it causes the display unit 35 to display a start registration page Ps in the state as shown in FIG. 11 (step S120).

[0073] When the user presses the registration button 76 and instructs the registration of a photo (step S121), the information processing unit 32 sends a photo registration request to the paddy field management device 10 (step S122). In response to the photo registration request, the control unit 12 sends confirmation data to the information terminal 30 (step S123), and causes the display unit 35 to display a confirmation screen Gs as shown in FIG. 12 via the information processing unit 32 (step S124). The confirmation data is information for displaying and functioning the confirmation screen Gs.

[0074] When the user presses the affirmative button By and a confirmation of the photo is instructed (step S125), the information processing unit 32 transmits a confirmation request to the paddy field management device 10. In the present embodiment, the confirmation request includes the data of the photographed or selected photo. The confirmation request may include information on the start date of the middle drying set in the date setting unit 70s (step S126). The control unit 12 stores the photo data included in the confirmation request in the storage unit 13 as the first start image S1. More specifically, the control unit 12 stores the first start image S1 in the storage 13s and stores the information on the URL of the link destination of the first start image S1 in the paddy field database 13d (step S127).

[0075] When the registration process in step S127 is completed, the control unit 12 transmits registration completion data to the information terminal 30 (step S128), and causes the display unit 35 to display a registration completion page Pm as shown in FIG. 13 via the information processing unit 32 (step S129). The registration completion data is information for displaying and functioning the registration completion page Pm.

[0076] When the information processing unit 32 receives an operation to return the page, such as the user pressing the return button r (step S130), it transmits a start registration request to the paddy field management device 10 (step S131). In response to the start registration request, the control unit 12 transmits start registration data to the information terminal 30 (step S132), and causes the display unit 35 to display a start registration page Ps as shown in FIG. 14 via the information processing unit 32 (step S133).

[0077] When the second button 72 is pressed by the user while the drain outlet is not selected (step S133), the information processing unit 32 switches to the state where the drain outlet is selected (step S134). When a photo is taken by the user's operation (step S135), the information processing unit 32 causes the display unit 35 to display a start registration page Ps including an image of the photo corresponding to the drain outlet as shown in FIG. 15 (step S136). On the other hand, when a photo is selected by the user's operation (step S135), the information processing unit 32 causes the display unit 35 to display the start registration page Ps in a state as shown in FIG. 15 (step S136).

[0078] When the registration of a photo is instructed by the user (step S137), the information processing unit 32 transmits a photo registration request to the paddy field management device 10 (step S138). In response to the photo registration request, the control unit 12 transmits confirmation data to the information terminal 30 (step S139), and causes the display unit 35 to display a confirmation screen Gs as shown in FIG. 16 via the information processing unit 32 (step S140).

[0079] When the confirmation of a photo is instructed by the user (step S141), the information processing unit 32 transmits a confirmation request to the paddy field management device 10 (step S142). The control unit 12 stores the photo data included in the confirmation request as the second start image S2 in the storage unit 13. More specifically, the control unit 12 saves the second start image S2 in the storage 13s and stores the information of the URL of the link destination of the second start image S2 in the paddy field database 13d (step S143).

[0080] The control unit 12 may obtain the scheduled end date of mid-drying in response to the confirmation request and store the obtained scheduled end date in the storage unit 13. Specifically, it is preferable to previously store in the storage unit 13 the mid-drying periods in the paddy fields registered in this system in the recent several years. The registration of the mid-drying periods in the recent several years may be enabled for the user to register using this system. Then, the control unit 12 may obtain the scheduled end date using the mid-drying start date (the date when mid-drying started) and the mid-drying periods in the recent several years, and store the obtained scheduled end date in the paddy field DB.

[0081] The control unit 12 may obtain the scheduled end date by performing calculations based on, for example, the following formulas (1) to (3). It is assumed that the calendar information is stored in the storage unit 13 for this calculation. The start date in formula (1) refers to the "day" of the middle trunk start date. For example, in the case of September 20th, it is 20 (days). The scheduled end date corresponds to the "day" of the scheduled end date, and the provisional end date is calculated as a provisional scheduled end date. Adoption conditions are appended in parentheses to formulas (2) and (3) respectively.

[0085] If the provisional end date is less than or equal to the number of days in the middle trunk start month, the control unit 12 obtains the scheduled end date according to formula (2). That is, if the control unit 12 satisfies the condition that the provisional end date is less than or equal to the number of days in the middle trunk start month, it sets the provisional end date as the scheduled end date. On the other hand, if the provisional end date is more than the number of days in the middle trunk start month, the control unit 12 obtains the scheduled end date according to formula (3). When using formula (3), that is, when satisfying the condition that the provisional end date is more than the number of days in the middle trunk start month, the control unit 12 sets the month following the middle trunk start month as the "month" of the scheduled end date.

[0086] The website of the Ministry of Agriculture, Forestry and Fisheries states that "extension of the mid-drying period through paddy rice cultivation" has been approved as a new methodology in J-Credit. Specifically, it is described that "if the mid-drying period is extended by 7 days or more from the average number of days of implementation in the paddy field over the past two years or more and undergoes a prescribed review, certification of 'credit' for the reduction amount can be obtained." Therefore, the paddy field management device 10 of this embodiment adopts a method of obtaining the scheduled end date with the reference number of days being the average of the mid-drying periods in the past two years and the suppression coefficient being 7 (days).

[0087] In the example of FIG. 18 where the mid-drying start date (implementation date) is set to September 20, 2024, the control unit 12 applies the start date of 20 (days), the reference number of days of 8 (days), and the suppression coefficient of 7 (days) to Equation (1) and calculates 34 (days) as the tentative end date (20 + 8 + 7 - 1 = 34). Next, the control unit 12 compares the calculated tentative end date with the number of days in September. Since the tentative end date of 34 (days) is more than the number of days in September, which is 30 (days), the control unit 12 obtains 4 (days) as the scheduled end date according to Equation (3) (34 - 30 = 4). Then, the control unit 12 adds 1 to 9 (month), which is the mid-drying start month, to make the "month" of the scheduled end date 10 (month), thereby obtaining "October 4th" as the scheduled end date.

[0088] However, in the system, the mid-drying period of the previous year may be used as the reference number of days. When the mid-drying periods of the recent several years are stored, not limited to the average number of these days, the reference number of days may be obtained by other methods such as weighting each year and then taking the average. This system may be configured to be able to register the reference number of days instead of the mid-drying periods of the recent several years. The suppression coefficient is not limited to 7 (days) and may be appropriately changed from the perspective of suppressing methane generation.

[0089] When the registration process is completed, the control unit 12 transmits the registration completion data to the information terminal 30 (step S145), and causes the display unit 35 to display a registration completion page Pm as shown in FIG. 17 via the information processing unit 32. By visually recognizing the registration completion page Pm, the user can confirm that the registration process at the start of the main work has been completed (step S146).

[0090] Incidentally, although the user does not need to log in to this system until the end of the main work, in this embodiment, for example, the scheduled end date can be confirmed as appropriate in the following flow. For example, when, in a state where the registration completion page Pm is displayed on the display unit 35, the user presses the list transition button R to indicate a return to the paddy field list (step S147), the information processing unit 32 transmits a list request to the paddy field management device 10 (step S148). In response to the list request, the control unit 12 transmits paddy field list data to the information terminal 30 (step S149), and causes the display unit 35 to display a paddy field list page Pa as shown in FIG. 4 or FIG. 20 via the information processing unit 32. In the case of a configuration in which a paddy field list page Pa as shown in FIG. 20 is displayed, the user can confirm the scheduled end date at this point. The same applies after logging in again (step S150).

[0091] When the information processing unit 32 receives a paddy field selection operation on the paddy field list page Pa (step S151), it transmits the selection data to the paddy field management device 10 (step S152). The control unit 12 compares the transmitted selection data with the paddy field DB, and by transmitting the extracted paddy field data to the information terminal 30 (step S153), causes the display unit 35 to display a paddy field information page Pb as shown in FIG. 18 via the information processing unit 32. By visually recognizing the paddy field information page Pb, the user can confirm the scheduled end date (step S154).

[0092] Next, based on the sequence charts of FIGS. 25 and 26, an example of the operation at the end of mid-season drainage registration will be described. For the same processes as those in FIGS. 23 and 24, appropriate omissions or simplifications will be made as appropriate. The paddy field management system 100 executes the processes of steps S101 to S104 according to the user's operation. That is, the control unit 12 causes the display unit 35 to display a paddy field list page Pa as shown in FIG. 4 or FIG. 20.

[0093] When the information processing unit 32 receives a selection operation of a paddy field (step S105), it transmits the selection data to the paddy field management device 10 (step S106). The control unit 12 causes the display unit 35 to display a paddy field information page Pb as shown in FIG. 5 by returning the paddy field data (step S107). The paddy field information page Pb may include a scheduled date display Dx (step S108). When the display of work is instructed (step S109), the information processing unit 32 transmits a work display request to the paddy field management device 10 (step S110). The control unit 12 causes the display unit 35 to display a work selection page Pc as shown in FIG. 6 by returning the work selection data (step S111) (step S112).

[0094] When the mid-season drainage end button 65 is pressed and the display of the registration page for the end of mid-season drainage of the paddy field is instructed (step S201), the information processing unit 32 transmits an end registration request to the paddy field management device 10 (step S202). The control unit 12 causes the display unit 35 to display an end registration page Pe as shown in FIG. 18 by transmitting the end registration data to the information terminal 30 in response to the end registration request (step S203) (step S204). The end registration data is information for displaying and functioning the end registration page Pe.

[0095] When the date of the end of the middle drying is set by an operation on the date setting unit 70e, the information processing unit 32 registers the set date as the end date of the middle drying (step S205). Further, when the first button 71 is pressed by the user in a state where the water intake is not selected, the information processing unit 32 switches to a state where the water intake is selected (step S206). When a photo is taken or selected by the user (step S207), the information processing unit 32 displays an end registration page Pe including an image of the photo corresponding to the water intake on the display unit 35 (step S208).

[0096] When photo registration is instructed (step S209), the information processing unit 32 transmits a photo registration request to the paddy field management device 10 (step S210). In response to the photo registration request, the control unit 12 transmits confirmation data to the information terminal 30 (step S211), and causes the display unit 35 to display a confirmation screen Gs configured in the same manner as the example of FIG. 12 (step S212).

[0097] When photo confirmation is instructed (step S213), the information processing unit 32 transmits a confirmation request to the paddy field management device 10. In the present embodiment, the confirmation request includes data of the taken or selected photo. The confirmation request may include information on the end date of the middle drying set in the date setting unit 70e (step S214). The control unit 12 stores the photo data included in the confirmation request as the first end image E1 in the storage unit 13. More specifically, the control unit 12 stores the first end image E1 in the storage 13s and stores information on the URL of the link destination of the first end image E1 in the paddy field database 13d (step S215). When the registration process in step S215 is completed, the control unit 12 transmits registration completion data to the information terminal 30 (step S216), and causes the display unit 35 to display a registration completion page Pm configured in the same manner as the example of FIG. 13 (step S217).

[0098] When the information processing unit 32 receives an operation to return a page (step S218), it transmits an end registration request to the paddy field management device 10 (step S219). In response to the end registration request, the control unit 12 transmits end registration data to the information terminal 30 (step S220), causing the end registration page Pe in a state where the first button 71 does not function to be displayed on the display unit 35 (step S221).

[0099] When the second button 72 is pressed by the user while the drain outlet is not selected, the information processing unit 32 switches to a state where the drain outlet is selected (step S222). When a photo is taken or selected by the user's operation (step S223), the information processing unit 32 causes the end registration page Pe including the image of the photo corresponding to the drain outlet to be displayed on the display unit 35 (step S224).

[0100] When the user instructs the registration of a photo (step S225), the information processing unit 32 transmits a photo registration request to the paddy field management device 10 (step S226). In response to the photo registration request, the control unit 12 transmits confirmation data to the information terminal 30 (step S227), causing the confirmation screen Gs configured in the same manner as the example of FIG. 16 to be displayed on the display unit 35 (step S228).

[0101] When the user instructs the confirmation of a photo (step S229), the information processing unit 32 transmits a confirmation request to the paddy field management device 10 (step S230). The control unit 12 stores the photo data included in the confirmation request as the second end image E2 in the storage unit 13. More specifically, the control unit 12 stores the second end image E2 in the storage 13s and stores the information of the URL of the link destination of the second end image E2 in the paddy field database 13d (step S231).

[0102] When the registration process is completed, the control unit 12 transmits registration completion data to the information terminal 30 (step S232), causing the registration completion page Pn as shown in FIG. 19 to be displayed on the display unit 35. The user can confirm that the registration process at the end of the middle stem has been completed by visually recognizing the registration completion page Pn (step S233).

[0103] Although each of the above processes has been described in the order of the step numbers attached to each figure, the order of the processes is not limited to these examples, and a part of the processes may be omitted. For example, the process of photographing or selecting a photo of the water intake as the first start image S1 and the process of photographing or selecting a photo of the drain outlet as the second start image S2 may be performed in either order. Similarly, the process of photographing or selecting a photo of the water intake as the first end image E1 and the process of photographing or selecting a photo of the drain outlet as the second end image E2 may be performed in either order. The setting of the midstream start date in step S117 does not need to be performed at the timing shown in FIG. 23, and the setting of the midstream end date in step S205 does not need to be performed at the timing shown in FIG. 25. The confirmation processes in steps S123 to S126 and the confirmation processes in steps S211 to S214 may be omitted. The processes in steps S131 and S132 may be omitted. In this case, the information processing unit 32 may perform the process in step S133 without communicating with the paddy field management device 10. Similarly, the processes in steps S219 and S220 may be omitted. In this case, the information processing unit 32 may perform the process in step S221 without communicating with the paddy field management device 10.

[0104] Next, with reference to the sequence chart of FIG. 27, an example of the operation until the production management record page Pk is displayed through the registration status browsing page Pj will be described. The second service can also be received by the information terminal 30, but here, the description will be made on the premise that the user uses the service via the management terminal 40.

[0105] When the user launches an application related to the second service of this system and the collation process for login is completed (steps S301 and S302), the control unit 12 acquires registration information (mid-field registration data) regarding the mid-fields of each paddy field associated with the user from the paddy field database 13d (step S303), and acquires a registration image (mid-field registration image) related to the start or end of mid-field weeding from the storage 13s (step S304). Then, the control unit 12 transmits browsing data including the mid-field registration data and the mid-field registration image related to the user to the management terminal 40 (step S305), and causes the management display unit 45 to display a registration status browsing page Pj as shown in FIG. 21 via the management processing unit 42 (step S306). The browsing data is information for displaying and functioning the registration status browsing page Pj.

[0106] When the display button 93 is pressed by the user and the management processing unit 42 receives a paddy field selection operation, it transmits paddy field selection data indicating the selected paddy field to the paddy field management device 10. The paddy field selection data includes the identification information of the paddy field corresponding to the pressed display button 93 (step S308). The control unit 12 acquires the mid-field registration data of the paddy field associated with the paddy field selection data from the paddy field database 13d (step S309), and acquires the mid-field registration image from the storage 13s (step S310). Then, the control unit 12 Record data transmits the one including the mid-field registration data and the mid-field registration image related to the paddy field to the management terminal 40 (step S311), and causes the management display unit 45 to display a production management record page Pk as shown in FIG. 22 via the management processing unit 42 (step S312). The user can utilize it by printing out the displayed production management record page Pk or saving it as a PDF.

[0107] As described above, the paddy field management device 10 in the present embodiment causes the display unit 35 to display the start registration page Ps in response to a display instruction for a screen related to the start of mid-season drainage, and causes the display unit 35 to display the end registration page Pe in response to a display instruction for a screen related to the end of mid-season drainage. The start registration page Ps accepts registration of a first start image S1 indicating a state where water intake into the paddy field is impossible and a second start image S2 indicating a state where water in the paddy field is being drained. The end registration page Pe accepts registration of a first end image E1 indicating a state where water intake into the paddy field is possible and a second end image E2 indicating a state where water drainage in the paddy field is impossible. Therefore, registration of these images that can be used for management during the mid-season drainage period can be smoothly promoted, enabling the user to efficiently manage the mid-season drainage period. Also, in the case of an application by text input or handwriting, it is difficult to confirm whether the mid-season drainage period has actually been extended, but in the paddy field management system 100, registration of a photo that allows the situation to be immediately confirmed is an essential condition. Therefore, the reliability of the mid-season drainage period that is finally determined can be enhanced.

[0108] The start registration page Ps has a function of accepting a registration operation for the start date of mid-season drainage, and the end registration page Pe has a function of accepting a registration operation for the end date of mid-season drainage. More specifically, the start registration page Ps includes a date setting unit 70s for setting the start date of mid-season drainage, and the end registration page Pe includes a date setting unit 70e for setting the end date of mid-season drainage. It is assumed that the user does not always register the photo immediately after shooting, but may register it several days later. If the date when the photo is registered is directly recorded as the start date or end date of mid-season drainage, a deviation will occur between the recorded mid-season drainage period and the actual mid-season drainage period. In this regard, if the start date and end date of mid-season drainage can be registered, an accurate mid-season drainage period can be recorded even in the case of registration several days after shooting.

[0109] However, the control unit 12 may extract the shooting date from the photo data and record it as the middle drying start date or the middle drying end date. For example, the control unit 12 may extract the shooting date from the first start image S1 and the second start image S2, and store the extracted shooting date in the storage unit 13 as the middle drying start date. Similarly, the control unit 12 may extract the shooting date from the first end image E1 and the second end image E2, and store the extracted shooting date in the storage unit 13 as the middle drying end date. Then, the control unit 12 may display the shooting date extracted from the first start image S1 and the second start image S2 on the registration completion page Pm as the middle drying start date, and may display the shooting date extracted from the first end image E1 and the second end image E2 on the registration completion page Pn as the middle drying end date. Also, the control unit 12 may use the extracted shooting date as the middle drying start date to obtain the scheduled end date of the middle drying. If the shooting dates of the first start image S1 and the second start image S2 are different from each other, the control unit 12 may display or notify an alert. Similarly, if the shooting dates of the first end image E1 and the second end image E2 are different from each other, the control unit 12 may display or notify an alert. Furthermore, the control unit 12 may add position information by GPS to the photographed photo.

[0110] The control unit 12 may obtain the scheduled end date of the mid-season drainage in the paddy field by using the start date of the mid-season drainage in the paddy field and the mid-season drainage periods of the recent several years of the paddy field registered in advance. Then, the control unit 12 may cause the obtained scheduled end date to be displayed on a registration completion page Pm (corresponding to FIG. 17) indicating that the first start image S1 and the second start image S2 have been registered. In this way, at the stage of registering the start image S, the scheduled end date of the mid-season drainage can be known, and the work schedule can be set in advance. The control unit 12 may cause the obtained scheduled end date to be displayed on an end registration page Pe (corresponding to FIG. 18). In this way, when the user opens the end registration page Pe prior to the end registration of the mid-season drainage, the scheduled end date can be confirmed in advance. Further, when the user opens the end registration page Pe for performing the end registration of the mid-season drainage, it can be confirmed whether there is no difference from the scheduled end date, whether the current day is after the scheduled end date, and the like. The control unit 12 may cause the obtained scheduled end date to be displayed on a paddy field list page Pa (see FIG. 20). In this way, the user can be made to confirm the scheduled end date at an early stage of screen transition, and a user who has registered a plurality of paddy fields can confirm the scheduled end dates of each of the plurality of paddy fields only on the paddy field list page Pa.

[0111] When information regarding the mid-season drainage of the paddy field is requested via the management terminal 40, the control unit 12 may cause a production management record page Pk including the start image S and the end image E to be displayed on the management display unit 45 of the management terminal 40 together with information regarding the start date and the end date of the mid-season drainage of the paddy field. As the information terminal 30, a smartphone or a tablet PC that can be easily carried to the paddy field is mainly used, but the screen of the smartphone is not suitable for checking the production management record page Pk. Therefore, in the present embodiment, an application related to the second service is separately provided so that the user can check the production management record page Pk using the management terminal 40 placed at home, office, or the like.

[0112] However, the application related to this system, that is, the paddy field management program 13p, may be configured to selectively use the first service and the second service. For example, when the user's login process is completed, the paddy field management device 10 may be configured to display an initial screen including a paddy field list button for transitioning to a paddy field list page Pa as shown in FIG. 4 and a registration status confirmation button for transitioning to a registration status viewing page Pj as shown in FIG. 21 on the display unit 35. In this case, the user can check the production management record page Pk on either the information terminal 30 or the management terminal 40. That is, when information regarding the mid-season drainage of a paddy field is requested via the information terminal 30, the control unit 12 may display the production management record page Pk including the start image S and the end image E related to the start date and end date of the mid-season drainage of the paddy field on the display unit 35.

[0113] Note that the paddy field management method of this embodiment includes a start registration process step of receiving an instruction to display a registration page for starting mid-season drainage of a paddy field and displaying a start registration page Ps for receiving registration of a start image S indicating that mid-season drainage has started on the display unit 35 of the information terminal 30, and an end registration process step of receiving an instruction to display a registration page for ending mid-season drainage of a paddy field and displaying an end registration page Pe for receiving registration of an end image E indicating that mid-season drainage has ended on the display unit 35, which are executed by one or more processors. When information regarding the mid-season drainage of a paddy field is requested via the information terminal 30 or the management terminal 40, the one or more processors execute a production management record display process step of displaying the production management record page Pk on the display unit 35 or the management display unit 45.

[0114] The above-described embodiments are examples in a paddy field management device, a paddy field management system, a paddy field management program, and a paddy field management method, and the technical scope of the present invention is not limited to these aspects. For example, in the above embodiment, an example of registering two images at each of the start and end of mid-drying was shown, but the present invention is not limited to this. The paddy field management system 100 may be configured to register only one image for either the start or the end of mid-drying, or may be configured to register only one image for both the start and the end of mid-drying. For example, the paddy field management device 10 and the paddy field management program 13p may be configured to request the first start image S1 at the start of mid-drying and at least one of the first end image E1 and the second end image E2 at the end of mid-drying. Alternatively, the paddy field management device 10 and the paddy field management program 13p may be configured to request the second start image S2 at the start of mid-drying and at least one of the first end image E1 and the second end image E2 at the end of mid-drying. Even in this case, since a part of the paddy field is shown together with the water intake in the first start image S1 and the first end image E1, the state of the water intake and the water volume of the paddy field can be confirmed, and since a part of the paddy field is shown together with the water intake in the second start image S2 and the second end image E2, the state of the drainage outlet and the water volume of the paddy field can be confirmed. Therefore, the start and end of mid-drying can also be determined by these combinations.

[0115] However, it is preferable to request the first start image S1 at the start of mid-drying, and it is more preferable to request two images at each of the start and end of mid-drying. However, the paddy field management system 100 may be configured to register three or more images for at least one of the start and end of mid-drying. At the start of mid-drying, the paddy field management system 100 may request registration of a photograph such as a panoramic view of the paddy field in addition to the first start image S1 and the first end image E1. Similarly, at the end of mid-drying, the paddy field management system 100 may request registration of a photograph such as a panoramic view of the paddy field in addition to the second start image S2 and the second end image E2.

[0116] The start registration page Ps may not have the first button 71 and the second button 72. For example, if the order of photo registration is determined as "water intake → drainage outlet", there is no need to request the user to make a selection. Therefore, instead of the first button 71 and the second button 72, when registering the first start image S1, a character string including "water intake", such as an explanatory text like "Please register a photo of the water intake" or simply the characters "water intake", may be displayed. Similarly, when registering the second start image S2, instead of the first button 71 and the second button 72, a character string including "drainage outlet" may be displayed. The same applies to the registration of the end image E.

[0117] The pages (Pa, Pb, Pc, Pe, Pj, Pk, Pm, Pn, Ps) illustrated in each figure are merely examples. In addition to the arrangement of each element displayed on each screen, aspects such as shape, font, and expression can be appropriately changed, and the selection of each element can also be freely made. For example, the characters of each virtual button, the explanatory text of each page, etc. are not limited to the examples in each figure and can be appropriately changed. Each figure is illustrated in grayscale, but in actual each screen, colors are appropriately used for characters, graphics, etc.
