Description

Technical Field

[0001] The invention relates to the technical field of machine transplanting, in particular to a hybrid rice seed production machine transplanting technology. Background Art

[0002] Manual planting of hybrid rice seeds has led to a substantial increase in the cost of hybrid rice cultivation. In addition, due to the low efficiency of manual planting operations, it is easy to cause season delays, misalignment of the flowering period of the parents, delay in the optimal planting period, affecting the growth and development of the parents and the coincidence of the flowering period, resulting in a decrease in yield. Especially for two-line hybrid rice seed production, it is easy to cause the female parent to encounter low temperature interference during the panicle differentiation period, resulting in fertility fluctuations, reducing seed purity, and causing significant losses to production. These have seriously restricted the development of the hybrid rice industry.

[0003] Currently, manual planting is used to complete the planting of male parent seedlings in two steps. Not only is the labor intensity high and difficult to complete, but the spacing between seedlings is uneven after manual planting, and the straightness and parallelism of the ridges are poor, resulting in poor planting quality, which is not conducive to the later growth and pollination of the seedlings.

[0004] Existing hybrid rice seed production technology relies on manual sowing and seedling raising, followed by staged transplanting. This method is not only labor-intensive and difficult to implement, but also results in uneven seedling spacing, poor ridge straightness and parallelism, and confusion in the order of transplanting male and female parents during staggered transplanting. This leads to poor planting quality and hinders later seedling growth and pollination. Therefore, a hybrid rice seed production technology using male parent transplanting technology was invented. Summary of the Invention

[0005] In view of the above problems and / or the problems existing in the existing hybrid rice seed production father machine transplanting technology, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a hybrid rice seed production father machine transplanting technology that can solve the above-mentioned existing problems.

[0007] To solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0008] A hybrid rice seed production father machine transplanting technology, which includes the following specific steps:

[0009] Step 1: Use different colored seedling trays to cultivate the male parent (if there are two phases of male parent, the colors of the first phase male parent and the second phase male parent are also separate) and the female parent seedlings;

[0010] Step 2: Place the seedling tray on the weight sensor and adjust the controller connected to the weight sensor according to the order of mechanical transplanting of the male and female parents;

[0011] Step 3: Install a speed sensor and a timer on the rice transplanter to calculate the travel distance of the rice transplanter so that the rice seedlings can be transplanted at equal intervals.

[0012] Step 4: Place a whiteboard in front of the rice transplanter and a laser transmitter at the front end of the rice transplanter so that personnel can use the laser on the whiteboard as a reference to adjust the forward angle of the rice transplanter so that the rice transplanter can move in a straight line.

[0013] Step 5: Place the male parent in the middle or on one side of the rice transplanter. There can be a row between the male parent and the female parent, or one row can be empty or not;

[0014] Step 6: Use a machine to transplant the seeds like you would in an ordinary rice field, or similar to traditional seed production.

[0015] As a preferred solution of the hybrid rice seed production father machine transplanting technology described in the present invention, the principle of step 2 is: assuming that it is necessary to first machine transplant A female parents and then machine transplant B male parents, each time a female parent or a male parent is taken away, the value on the weight sensor will change. At this time, the controller will count it as 1 time, and the cycle will continue. When the number of times the female parent is taken away is A+1, the controller will control the alarm connected to it to remind. When the number of times the female parent is taken away is AN (where N is less than A), if the male parent is taken away at this time, the controller will control the alarm connected to it to remind. Conversely, when the male parent is taken away, the principle is the same as that of taking away the female parent.

[0016] As a preferred solution of the hybrid rice seed production father machine transplanting technology described in the present invention, the principle of step three is: assuming that the distance between the seedlings is C, then when the speed D detected by the speed sensor × the time E calculated by the timer = distance C, the seedlings will be machine transplanted, and the data of the speed sensor and the timer will be reset to zero, and this cycle will be repeated so that the seedlings can be machine transplanted at equal intervals.

[0019] As a preferred solution of the hybrid rice seed production parent machine transplanting technology described in the present invention, the said solution A includes the following four solutions:

[0036] f. From left to right (or from right to left), place the N1 row of maternal parents, the paternal parents, and the N2 row of maternal parents in order;

[0037] Among them, N is adjusted according to the rice transplanter selected in actual production conditions, and the number of empty rows can also be adjusted according to actual conditions;

[0046] As a preferred solution of the hybrid rice seed production father machine transplanting technology described in the present invention, the ordinary transplanting method in step six is: assuming that the field is a rectangle (the same operation applies to irregular fields in actual production), the rice transplanter enters from the lower right entrance of the field and starts transplanting, circles around the ridge, and lifts the machine head after transplanting the seedlings at the lower left of the field without transplanting seedlings, leaving an aisle and driving to the lower right of the field to start the next circle, repeating the above operation in circles from the outside to the inside, and after the entire field is transplanted, driving out from a suitable exit to end the transplanting work.

[0047] As a preferred solution of the hybrid rice seed production father machine transplanting technology described in the present invention, the traditional seed production transplanting method in step six is: assuming that the field is a rectangle (the same operation applies to irregular fields in actual production), the rice transplanter enters from the lower right entrance of the field and starts transplanting, circles around the ridge, and lifts the machine head without transplanting seedlings after transplanting the upper rightmost part; leaves an aisle and drives to the upper leftmost part to start transplanting, and lifts the machine head without transplanting seedlings after transplanting the lower leftmost part; leaves an aisle and drives back to the lower right to start transplanting a new circle, repeats the above operation in circles from outside to inside, and drives out from a suitable exit after the entire field is planted to end the rice transplanting work. The entire rice transplanter's driving route presents a closed "U"-shaped route. When the rice transplanter seedlings adopt any one of the A-swinging methods, there are no empty rows or 1-2 empty rows between the two circles of seedlings in the field according to actual production conditions. When the rice transplanter seedlings adopt any one of the B-swinging methods, the rice transplanter can be transplanted close to the previous circle of seedlings in the field without leaving any empty rows.

[0048] Compared with existing technologies:

[0049] 1. Using a rice transplanter to transplant the seedlings will not only greatly reduce labor intensity but also improve the efficiency of machine transplanting.

[0050] 2. By setting up a weight sensor to detect the weight of the seedlings of the father and mother, and then using the controller to determine the number of times the seedlings are taken away, the order confusion can be avoided when the father and mother are transplanted alternately.

[0051] 3. By setting a speed sensor to detect the travel speed of the rice transplanter and setting a timer to calculate the travel time of the rice transplanter, the rice seedlings can be transplanted at equal intervals.

[0052] 4. By setting up a whiteboard and a laser transmitter, personnel can use the laser irradiated on the whiteboard as a reference to adjust the forward angle of the rice transplanter, thereby enabling the rice transplanter to move in a straight line. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figure 2 It is a schematic diagram of the traditional seed production machine of the present invention. DETAILED DESCRIPTION

[0055] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0056] The present invention provides a hybrid rice seed production parent machine transplanting technology, please refer to Figure 1-Figure 2 , including the following specific steps:

[0057] Step 1: Use different colored seedling trays to cultivate the male parent (if there are two phases of male parent, the colors of the first phase male parent and the second phase male parent are also separate) and the female parent seedlings respectively;

[0058] Step 2: Place the seedling tray on the weight sensor and adjust the controller connected to the weight sensor according to the order of mechanical transplanting of the male and female parents;

[0059] The principle is as follows: assuming that A female parents need to be machine-inserted first, and then B male parents need to be machine-inserted, each time a female parent or male parent is removed, the value on the weight sensor will change. At this time, the controller will count it as 1 time, and the cycle will continue. When the number of female parents removed is A+1, the controller will control the alarm connected to it to remind you. When the number of female parents removed is AN (where N is less than A), if the male parent is removed, the controller will control the alarm connected to it to remind you. Conversely, when the male parent is removed, the principle is the same as when the female parent is removed.

[0060] Step 3: Install a speed sensor and a timer on the rice transplanter to calculate the travel distance of the rice transplanter so that the rice seedlings can be transplanted at equal intervals.

[0061] The principle is as follows: Assuming the distance between the seedlings is C, when the speed D detected by the speed sensor × the time E calculated by the timer = distance C, the seedlings will be transplanted by machine, and the data of the speed sensor and the timer will be reset to zero. This cycle will be repeated to enable the seedlings to be transplanted at equal intervals.

[0062] Step 4: Place a whiteboard directly in front of the rice transplanter and a laser transmitter at the front end of the rice transplanter so that personnel can use the laser light on the whiteboard as a reference to adjust the forward angle of the rice transplanter so that the rice transplanter can move in a straight line. The whiteboard is placed on the ridge of the field, and the laser transmitter is arranged perpendicular to the rice transplanter. During operation, the forward angle of the rice transplanter is adjusted according to the left and right position of the laser light on the whiteboard.

[0063] Step 5: Place the male parent in the middle or on one side of the rice transplanter. There can be a row between the male parent and the female parent, or one row can be empty or not;

[0069] c. From left to right (or from right to left), place N rows of mother copies, a blank row, and then the father copy;

[0070] d. Place N rows of maternal and paternal copies in sequence from left to right (or from right to left);

[0071] Among them, N is adjusted according to the rice transplanter selected in actual production conditions, and the number of empty rows can also be adjusted according to actual conditions;

[0072] The specific method of A is:

[0073] a.~~~~~~~~~~~~~○×1×2;

[0074] b.~~~~~~~~~~~~~~~~~×1×2;

[0079] b. From left to right (or from right to left), place the N1 row of female parents, the first-stage male parents, the second-stage male parents, a blank row, and the N2 row of female parents in order;

[0080] c. From left to right (or from right to left), place the N1 row of maternal parents, the first-stage paternal parents, the second-stage paternal parents, and the N2 row of maternal parents in order;

[0081] d. From left to right (or from right to left), place N1 row of mother copies, a blank row, father copies, a blank row, and N2 row of mother copies in order;

[0087] b.~~~~~~~~N1~~~~~~~~~~×1×2○~~~~~~~~N2~~~~~~~~

[0088] c.~~~~~~~~~~N1~~~~~~~~~×1×2~~~~~~~~~N2~~~~~~~~~~

[0090] e.~~~~~~~~~~N1~~~~~~~~~×○~~~~~~~~~~N2~~~~~~~~~~

[0091] f.~~~~~~~~~~~~N1~~~~~~~~~~~×~~~~~~~~~~N2~~~~~~~~~~~.

[0092] ~~~~~~~~~~~~~~~~ represents the maternal parent; × represents the paternal parent; ×1 represents the first-period paternal parent; ×2 represents the second-period paternal parent, ○ represents a blank line;

[0093] Step 6: Plant the seeds by machine like planting in ordinary rice fields, or similar to traditional seed production;

[0094] in:

[0095] The common transplanting method is: assuming the field is rectangular (the same operation applies to irregular fields in actual production), the rice transplanter drives in from the lower right entrance of the field to start transplanting, circles around the ridge, and lifts the machine head after transplanting the seedlings at the lower left of the field without planting seedlings, leaving an aisle and driving to the lower right of the field to start the next circle, repeating the above operation in circles from the outside to the inside. After the entire field is planted, it drives out from the appropriate exit to end the transplanting work. The entire rice transplanter's driving route presents a closed "U"-shaped route. When the rice transplanter seedlings adopt any of the A-positioning methods, there will be no empty rows or 1-2 empty rows between the two circles of seedlings in the field according to the actual production situation. When the rice transplanter seedlings adopt any of the B-positioning methods, the rice transplanter can be planted next to the previous circle of seedlings in the field without leaving any empty rows.

[0096] The traditional seed transplanting method is: assuming the field is a rectangle (the same operation applies to irregular fields in actual production), the rice transplanter drives in from the lower right entrance of the field to start transplanting, circles around the ridge, and lifts the machine head when finishing transplanting the upper rightmost row without planting seedlings; leaves an aisle and drives to the upper leftmost row to start transplanting, and lifts the machine head when finishing transplanting the lower leftmost row without planting seedlings; leaves an aisle and drives back to the lower right to start transplanting a new circle, repeating the above operation in circles from outside to inside, and after the entire field is planted, drives out from the appropriate exit to end the transplanting work. The entire rice transplanter's driving route presents a closed "U"-shaped route. When the rice transplanter seedlings adopt any of the A-positioning methods, there are no empty rows or 1-2 empty rows between the two circles of seedlings in the field according to the actual production situation. When the rice transplanter seedlings adopt any of the B-positioning methods, the rice transplanter can be transplanted next to the previous circle of seedlings in the field without leaving any empty rows.

[0097] Among them, in the present invention, the row ratio of the parent plants is 2:7 (9-row transplanter), the first-phase male plant and the second-phase male plant each have one row, and the female plant has 7 rows, which belongs to the same machine transplanting and the method is simple.

[0098] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
