Description

Technical Field

[0002] Barley is the main food, fuel and livestock feed for residents in the Tibetan areas of China, and is also the raw material for the production of beer, medicine and health products. Drought has a very serious impact on highland barley, making it difficult to accumulate nutrients in the later stage of highland barley, and sometimes causing a total crop failure, which has a serious impact. Therefore, it is necessary to conduct drought resistance identification tests on highland barley to experiment with its growth and survival ability in a drought environment, so as to guide farmers to choose crop varieties suitable for local climatic conditions, adopt reasonable irrigation and farming measures, and improve the drought resistance and yield of barley.

[0003] The patent with publication number CN215898490U discloses a kind of high-throughput corn seedling drought resistance identification drip irrigation device, a roll paper seedling system is placed in the seedling box, the roll paper seedling system is filled with organic soil, and corn seedlings are planted in the roll paper seedling system; the high-throughput corn seedling drought resistance identification drip irrigation device adopts the bottom drip irrigation method instead of the conventional top irrigation, slowly releases water through the bottom drip irrigation belt, uses the infiltration layer to absorb water to keep the water distribution at the bottom of the seedling box consistent, and the water is evenly diffused into the soil of the entire seedling box through the capillary action of the soil. The amount of water can be accurately adjusted by the control valve on the water inlet pipe each time, and the amount of water can be determined by adjusting the irrigation time, which can be applied to drought resistance tests with different moisture gradients. Water is transferred from the bottom seepage layer to the top soil, and a small gradient environment of water will be formed at the bottom of the soil for a long time due to the factor of water gravity, which is more similar to the actual planting environment in the field. Before it rains, the entire nursery box is covered with a awning. At other times, the awning is folded up to receive sunlight, which is conducive to reducing soil moisture and achieving the purpose of rapid drought. The drought-resistant corn materials obtained through two rounds of drought treatment screening can be directly taken out together with the nursery holes and directly transplanted into the natural environment of the field.

[0004] In the above technical scheme, although the bottom drip irrigation method is adopted instead of the conventional top irrigation to slowly release water through the bottom drip irrigation belt, and the water distribution at the bottom of the seedling box is kept consistent by absorbing water through the absorption layer, in the above technical scheme, if drought resistance tests with different moisture gradients are required, multiple experiments are required, and the irrigation amount of each experiment is different, so as to conduct drought resistance tests of corn under different moisture gradients; it is time-consuming and labor-intensive, and it is impossible to conduct drought resistance experiments on corn under different moisture gradients at the same time.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Example 1 like Figures 1 to 20As shown, an embodiment of the present invention provides a high-throughput drought resistance identification drip irrigation device for barley and highland barley, comprising a gradient water drip tank device, a seedling box 3, a water tank 4, a sunshade 12 and a daylight lamp 13. The gradient water drip tank device is connected to the water tank 4. The water tank 4 is placed on a water tank rack so that the water in the water tank 4 flows out under the action of gravity and enters the gradient water drip tank device.

[0028] The sunlight lamp 13 is arranged on the sunshade 12 and is located directly above the seedling box 3 , so as to provide sunlight to the barley and highland barley 8 , thereby providing drought stress conditions for the barley and highland barley 8 .

[0029] like Figure 4 As shown, a plurality of partition plates 31 arranged at equal intervals are provided inside the seedling box 3; the partition plates 31 are used to divide the internal space of the seedling box 3 into a plurality of seedling units so as to plant barley and highland barley in different seedling units. The partition plates 31 are fixed to the seedling box 3. It should be noted that the embodiment of the present invention does not limit the fixed connection method of the partition plates 31 and the seedling box 3. For example, the partition plates 31 and the seedling box 3 are connected by rivets.

[0030] In addition, the embodiment of the present invention does not limit the number of partition plates 31. The embodiment of the present invention takes the example of dividing the interior of the seedling raising box 3 into six seedling raising units with 5 partition plates 31 as an example.

[0031] like Figure 1 As shown, the gradient water volume drip tank device includes an annular pipe 1 and a water volume regulator 2 arranged below the annular pipe 1 .

[0032] When in use, the upper end of the annular tube 1 is connected to the water tank 4 , and a plurality of water outlets 11 arranged at equal intervals are provided on the annular tube 1 ; wherein the annular tube 1 is arranged right above the seedling box 3 .

[0033] Specifically, the number of water outlets 11 above each seedling raising unit of the seedling raising box 3 is the same. It should be noted that the embodiment of the present invention does not limit the number of water outlets 11 above each seedling raising unit. For example, the embodiment of the present invention is described by taking two water outlets 11 above each seedling raising unit as an example.

[0034] like Figure 4 and 12 As shown, the water regulator 2 is arranged between the annular tube 1 and the seedling box 3, and the water regulator 2 includes a regulating component 21 and a control component 22 arranged at the end of the regulating component 21.

[0035] The control component 22 is used to control the movement of the regulating component 21 so as to adjust the irrigation amount of each seedling raising unit.

[0036] Specifically, Figure 6and 7 As shown, the regulating assembly 21 includes a fixing frame 21a and a water regulating rod 21b. Specifically, the fixing frame 21a is arranged at the upper end of the seedling box 3 and is slidably connected to the water regulating pipe 21b. Figure 5 As shown, a plurality of through holes are provided on the water regulating tube 21b, and the plurality of through holes are used to be connected to the respective water outlets 11, so that water flows through the through holes of the fixing frame and the irrigation holes on the water regulating rod 21b and is drip-irrigated into the seedling unit.

[0037] Specifically, Fig.13 and 14 , which is a schematic structural diagram of a fixing frame 21a. An arc-shaped slide groove 21d is provided on the fixing frame 21a, and the arc-shaped slide groove 21d is used for sliding connection with a water volume regulating rod 21b.

[0038] like Fig.15 , which is a schematic diagram of the structure of the water volume regulating pipe 21b; the water volume regulating pipe 21b is a C-shaped cross bar, and the cross bar is provided with water injection holes.

[0039] The water injection holes on the water volume regulating pipe 21b include two groups, such as Fig.18 As shown, one group includes the first water holes 5 , and the other group includes the second water holes 6 .

[0040] The diameters of the first irrigation holes 5 in different groups increase successively, and the diameters of the first irrigation holes 5 in the same group are the same, so as to drip different amounts of water into each seedling box.

[0041] The second irrigation holes 6 in different groups have the same diameter, and the diameters of the second irrigation holes 6 in the same group are all the same, so that the same amount of water can be dripped into the pots of each seedling raising unit.

[0042] In actual use, the number of groups of the first irrigation holes 5 and the second irrigation holes 6 corresponds to the number of the seedling raising units. In use, each seedling raising unit corresponds to a group of first irrigation holes 5 and a group of second irrigation holes 6 above.

[0043] The control assembly 22 includes a threaded rod 22a and a positioning portion 22b.

[0044] like Figure 8 and 15 As shown in FIG. 1 , the threaded rod 22a is disposed at one end of the water volume regulating rod 21b and is threadedly connected to the fixing frame 21a and the water volume regulating rod 21b, respectively.

[0045] Specifically, Fig.17 and 20As shown, the left idle ring 23 and the right idle ring 24 are respectively provided at both ends of the connection between the threaded rod 22a and the water volume regulating rod 21b, wherein the outer diameters of the left idle ring 23 and the right idle ring 24 are larger than the outer diameters of the connection hole of the water volume regulating rod 21b, so that the threaded rod 22a is limitedly set on the water volume regulating rod 21b; when in use, under the action of the left idle ring 23 and the right idle ring 24, the threaded rod 22a idles in the connection hole of the water volume regulating tube 21b. Among them, a thread is provided on the side where the threaded rod 22a is connected to the fixing frame 21a; In actual application, the operator manually rotates the threaded rod 22a, and the threaded rod 22a uses the limiting effect of the left idling ring 23 and the right idling ring 24 to drive the water regulating tube 21b to slide outward from the arc-shaped slide groove 21d of the fixed frame 21a until the irrigation hole set on the water regulating tube 21b is connected with the water outlet 11, so that the water in the annular tube 1 flows out from the water outlet 11 into the irrigation hole on the water regulating tube 21b, and then drips into the seedling unit through the irrigation hole.

[0046] like Figure 8 As shown, the positioning part 22b includes a position sensor 22b-1, a lifting column 22b-2 and a control block 22b-3; The position sensor 22b-1 is disposed in the linear slot 21c of the water volume regulating tube 21b, and when the second water filling hole 6 is aligned with the water outlet 11, the position sensor 22b-1 and the lifting column 22b-2 are located on the same straight line; The lifting column 22b-2 is connected to the control block 22b-3; The control block 22b-3 is provided with a laser structure module.

[0047] When in use, while the second water filling hole 6 is aligned with the water outlet 11, the laser receiving module set on the control block 22b-3 receives the laser sent by the position sensor 22b-1, and then the laser structure module sends information to the controller of the control block 22b-3, and the controller controls the lifting column 22b-2 to descend into the linear slot 21c on the water volume regulating tube 21b to fix the water volume regulating tube 21b on the fixing frame 21a, so that the second water filling hole 6 is aligned with the water outlet 11 and fixed at the same time to prevent the water volume regulating tube 21b from moving. After use, the operator can use the reset button on the control block 22b-3 to raise the lifting column 22b-2 until it leaves the linear slot 21c for the next experiment.

[0048] It should be noted that the control method of the controller in the control block 22b-3 is a prior art and the embodiment of the present invention does not make any improvements thereto.

[0049] The working principle of the control component 22 is: In the initial state, the end of the water regulating tube 21b is located at the innermost side of the fixing frame 21a, and the water outlet 11 is blocked by the tube body of the water regulating tube 21b, so that the water cannot flow out of the water outlet 11; like Fig.17 As shown, the operator manually rotates the threaded rod 22a for two circles, so that the threaded rod 22a drives the water regulating tube 21b to slide to the outside of the fixed frame 21a, and then aligns the second irrigation hole 6 with the water outlet 11, so that the same amount of water can be dripped to each seedling unit at the same time; at the same time, the laser receiving module receives the laser sent by the position sensor 22b-1, and then the laser structure module sends information to the controller of the control block 22b-3, and the controller controls the lifting column 22b-2 to descend and enter the linear groove 21c on the water regulating tube 21b, and then the operator can press the reset button on the control block 22b-3 to raise the lifting column 22b-2, so that the operator continues to manually rotate the threaded rod 22a for two circles, so that the threaded rod 22a drives the water regulating tube 21b to continue to slide to the outside of the fixed frame 21a, and then aligns the first irrigation hole 5 with the water outlet 11, so that different amounts of water can be dripped to each seedling unit at the same time.

[0050] The gradient water drip tank device provided by the embodiment of the present invention is used in two experimental modes: Method 1: Step 1: Plant multiple barley 8 of the same variety used in the experiment in different seedling units in the seedling box 3; Step 2: The operator manually rotates the threaded rod 22a for a total of 4 turns, so that the first irrigation hole 5 is connected to the water outlet 11, and then the barley 8 in each seedling unit is irrigated from bottom to top through the first irrigation hole 5. Since the inner diameters of the second irrigation holes 6 above different seedling units are different, the irrigation amount of each seedling unit is different, and then by observing the growth of barley 8, the effect of different irrigation amounts on the drought resistance of barley under the same drought stress and the same variety is studied.

[0051] Method 2: Step 1: Planting a plurality of different varieties of barley 8 for use in the experiment in different seedling units in the seedling box 3; Step 2: The operator manually rotates the threaded rod 22a for a total of 2 circles to connect the second irrigation hole 6 with the water outlet 11, and then drips the same amount of water from top to bottom to the barley 8 in each seedling unit through the second irrigation hole 6 until the soil moisture of each seedling unit reaches the experimental required humidity, and then the effects of different varieties on the drought resistance of barley can be studied under the same irrigation amount and the same drought stress.

[0052] It should be noted that the embodiment of the present invention is described as follows: the total number of rotations of the threaded rod 22a is 4, and when the threaded rod 22a rotates two times, the second water filling hole 6 is aligned and connected with the water outlet 11; when the threaded rod 22a rotates four times, the first water filling hole 5 is aligned and connected with the water outlet.

[0053] Example 2 Based on Example 1, different from Example 1, the gradient water volume drip tank device provided in this embodiment of the present invention is further provided with a horizontal drip irrigation pipe 7.

[0054] like Figure 4 As shown, the horizontal drip irrigation pipe 7 is arranged on the inner bottom surface of the seedling raising box 3, and the outer side thereof is wrapped with a water-absorbing sponge 9 so as to evenly infiltrate the water in the horizontal drip irrigation pipe 7 into the soil in each seedling raising unit.

[0055] Specifically, after one end of the horizontal drip irrigation pipe 7 passes through the seedling box 3 , a drainage port 71 is provided on the outside thereof, and a water outlet valve is provided at the drainage port 71 to discharge excess water out of the seedling box 3 .

[0056] The horizontal drip irrigation pipe 7 is provided with a plurality of drip irrigation holes arranged at equal intervals.

[0057] Specifically, the water inlets of the horizontal drip irrigation pipe 7 and the annular pipe 1 are connected and are both connected to the water tank 4. In this way, when the drought resistance identification drip pot experiment needs to be carried out through the annular pipe 1, the water inlet valve arranged on the annular pipe 1 is opened, and the water inlet valve on the horizontal drip irrigation pipe 7 is closed at the same time.

[0058] When the barley 8 needs to be drip-irrigated from bottom to top, the water inlet valve arranged on the annular pipe 1 is closed, and the water inlet valve on the horizontal drip irrigation pipe 7 is opened at the same time.

[0059] Example 3 Based on Example 1, what is different from Examples 1 and 2 is that Fig.21 and 22 As shown, a reflective film 10 is provided on the sunshade 12 provided in the embodiment of the present invention so as to increase the illumination intensity of the fluorescent lamp 13, increase the intensity of drought stress, and shorten the experimental period.

[0060] Application Case 1: Taking the effect of different irrigation amounts on the drought resistance of barley 8 of the same variety of barley and highland barley under the same drought stress as an example, the operation method of the high-throughput drought resistance identification drip irrigation device for barley and highland barley provided by the present invention is as follows: Step 1: Plant six barley plants of the same variety in different seedling units in the seedling box 3; Step 2: Turn on the fluorescent lamp 13 to expose the barley 8 to sunlight, and set reflective films 10 around the sunshade frame 12; Step 3: The operator manually rotates the threaded rod 22a four times, so that the threaded rod 22a drives the water regulating tube 21b to move toward the outside of the fixing frame 21a, until the first water filling hole 5 on the water regulating tube 21b is connected with the water outlet 11; Step 4: Open the water inlet valve on the annular tube 1, so that the water in the water tank 4 enters the first water hole 5 through the water outlet 11 of the annular tube 1, and then the water flows out from the first water hole 5 and drips different amounts of water to the seedling unit; Step 5: Observe the growth of barley and highland barley to study the effect of different irrigation amounts on the drought resistance of barley and highland barley 8 under the same variety and the same drought stress.

[0061] Application Case 2: Taking the study of the effects of different varieties on the drought resistance of barley and highland barley under the same irrigation amount and the same drought stress as an example, the operation method of the high-throughput drought resistance identification drip irrigation device for barley and highland barley provided by the present invention is as follows: Step 1: Plant six different varieties of barley in different seedling units in the seedling box 3; Step 2: Turn on the fluorescent lamp 13 to expose the barley 8 to sunlight, and set reflective films 10 around the sunshade frame 12; Step 3: The operator manually rotates the threaded rod 22a two circles, so that the threaded rod 22a drives the water regulating tube 21b to move to the outside of the fixing frame 21a, until the second water filling hole 6 on the water regulating tube 21b is connected with the water outlet 11; At this time, after receiving the information sent by the laser receiving module, the control block 22b-3 controls the lifting column 22b-2 to descend until the lifting column 22b-2 enters the linear slot 21c, so as to fix the water volume adjustment component 21b to the fixing frame 21a and align the second water filling hole 6 with the water outlet 11; Step 4: Open the water inlet valve on the annular tube 1, so that the water in the water tank 4 enters the second water hole 6 through the water outlet 11 of the annular tube 1, and then the water flows out from the second water hole 6 and drips the same amount of water into the seedling raising unit; Step 5: After the soil moisture in each seedling unit reaches the required humidity of the experiment through the humidity sensors installed in each seedling unit, the growth of barley and highland barley is observed to study the effects of different varieties on the drought resistance of barley and highland barley 8 under the same irrigation amount and the same drought stress.

[0062] It should be noted that after one experiment is finished, the soil in the seedling box 3 and the soaked sponge 9 need to be replaced to avoid affecting the next experiment.
