Description

Technical Field

[0001] The invention relates to the technical field of grain planting, and in particular to a green zinc-rich, selenium-rich and high-calcium grain planting method. Background Art

[0002] In modern agricultural practice, zinc-rich, selenium-rich, and high-calcium grains are increasingly favored by the market as a type of agricultural product that is rich in nutrition and high in health value. These grains are mainly planted by farmers to meet the growing market demand. However, in the planting process, in order to improve the quality of crops, especially to increase the content of trace elements such as zinc, selenium, and calcium, farmers generally use water and fertilizer irrigation to supplement nutrients.

[0003] In actual operation, current water and fertilizer irrigation equipment can usually only fertilize local parts of the plants. Although this local irrigation method can concentrate nutrient supply, local irrigation can easily lead to uneven distribution of nutrients in the soil, causing deviations in the absorption of nutrients by crop roots, affecting the overall growth balance. Secondly, if the amount of local fertilization is not properly controlled and excessive amounts occur, it will not only cause fertilizer waste, but may also cause diseases such as root rot and root burn, and even lead to plant death in severe cases. In addition, it is difficult for existing water and fertilizer irrigation equipment to accurately control the amount of irrigation for each plant, so that there are often large differences in the amount of irrigation between different plants, which affects the uniformity and consistency of crop growth, thereby affecting the overall yield. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a green zinc-rich, selenium-rich, and high-calcium grain planting method, which uses a grain planting water and fertilizer irrigation device, which includes: a main unit, a storage mixing unit, an irrigation drive unit, and a surround irrigation unit. The method includes the following steps:

[0006] Step 1: Choose a planting site that is suitable for the growth needs of zinc-rich, selenium-rich and high-calcium grains;

[0007] Step 2: Use automatic fertilization equipment to apply base fertilizer;

[0008] Step 3: Select high-quality grain seeds, sterilize, germinate, and enrich them with zinc and selenium to improve the germination rate and initial growth ability;

[0009] Step 4: Sow the treated seeds accurately;

[0010] Step 5: During the critical growth stage of the crop, liquid fertilizer containing zinc, selenium and calcium is irrigated to the roots of the crop through water and fertilizer irrigation equipment. The specific irrigation process is as follows:

[0011] In the initial state, the feed opening and closing piston is separated from the branch pipe, and the water and fertilizer in the mixed storage cylinder enter the shunt pipe through the connecting pipe, and then enter each branch pipe from the shunt pipe, and enter the quantitative cylinder from the branch pipe, and are temporarily stored in the quantitative cylinder; through the cooperation of the handle and the universal wheel, the equipment is moved to the grain planting field, and the universal wheel is aligned with the gap between two adjacent rows of crops;

[0012] When in use, the device is moved to the grain planting site by cooperating with the handle and the universal wheel, and the universal wheel is aligned with the gap between two adjacent rows of crops. Then the position of the device is adjusted by the handle so that the opening of the ring tube is aligned with the stem of the plant.

[0013] The driving motor is started, and the output end of the driving motor drives the first gear to rotate through the transmission shaft, and the first gear drives the second gear to rotate through the double-sided rack, and the second gear drives the screw to rotate through the rotating shaft. When the screw rotates, the first lifting plate and the second lifting plate move upward along the screw under the guidance and limiting action of the first guide slide bar and the second guide slide bar respectively, and the first lifting plate and the second lifting plate drive the feed opening and closing piston and the discharge opening and closing piston to move upward respectively. When the discharge opening and closing piston is not completely separated from the discharge pipe, the feed opening and closing piston is plugged into the bottom end of the branch pipe to prevent water and fertilizer from entering the quantitative cylinder during irrigation;

[0014] The feed opening and closing piston and the discharge opening and closing piston are continuously driven by the driving motor to move upward until the discharge opening and closing piston is away from the discharge pipe. After the discharge pipe is opened, water and fertilizer enter the ring pipe through the hose, and then are sprayed to the surrounding side of the plant stem by a plurality of spray heads at the bottom of the ring pipe;

[0015] In addition, when the second lifting plate moves upward, the second guide slide bar moves upward accordingly, so the second guide slide bar can drive the pusher to move upward. During the upward movement of the pusher, the cooperation between the inclined rod in the pusher and the inclined surface at the bottom of the protrusion can push the protrusion to move. The protrusion pushes the movable rod to move through the connecting rod, and the movable rod pushes the ring tube to move, so that the ring tube can be set outside the stem of the plant, and then water and fertilizer can be sprayed around the periphery of the stem.

[0016] When all the water and fertilizer in the metering cylinder are discharged, the driving motor drives the transmission shaft to rotate in the opposite direction to the previous direction, so that the first lifting plate and the second lifting plate move downward along the screw rod, and the first lifting plate and the second lifting plate respectively drive the feed opening and closing piston and the discharge opening and closing piston to move downward until the feed opening and closing piston is separated from the branch pipe and the discharge opening and closing piston is fully plugged into the discharge pipe. At this time, the metering cylinder can be replenished and the next crop can be watered. In addition, when the second lifting plate moves downward, the second guide slide bar moves with it, and the second guide slide bar drives the limit rod and the inclined rod in the pusher to move downward. When the inclined rod is reset, the movable rod is reset under the action of the rebound force of the reset spring, so that the protrusion and the ring tube are reset;

[0071] In summary, when irrigating the plants, the drive motor 302 is started, the output end of the drive motor 302 drives the transmission shaft 303 to rotate, the transmission shaft 303 drives the first gear 304 to rotate, the first gear 304 drives the double-sided rack 306 meshing with it to move, and when the double-sided rack 306 moves, it drives the second gear 401-14 meshing with it to rotate, and the second gear 401-14 drives the screw rod 401-6 to rotate through the rotating shaft 401-13. When the screw rod 401-6 rotates, the first lifting plate 401-7 and the second lifting plate 401-8 are separated. Under the guidance and limiting action of the first guide slide bar 401-11 and the second guide slide bar 401-12, the first lifting plate 401-7 and the second lifting plate 401-8 respectively drive the feed opening and closing piston 401-9 and the discharge opening and closing piston 401-10 to move upward. When the discharge opening and closing piston 401-10 is not completely separated from the discharge pipe 401-5, the feed opening and closing piston 401-9 is plugged into the bottom end of the branch pipe 401-3 to prevent the water and fertilizer from entering the metering cylinder 401-4 during the irrigation process. The feed opening and closing piston 401-9 and the discharge opening and closing piston 401-10 continue to move upward through the driving motor 302 until the discharge opening and closing piston 401-10 is away from the discharge pipe 401-5. After the discharge pipe 401-5 is opened, the water and fertilizer are discharged to irrigate the plants. During the process of irrigating the plants, water and fertilizer will not be added into the metering cylinder 401-4. When all the water and fertilizer in the metering cylinder 401-4 are discharged for irrigation, the discharge pipe 401-5 is closed and refilled to irrigate the next plant. In this way, the irrigation amount of each plant can be controlled, so that the difference in irrigation amount between different plants is small, which is not easy to affect the uniformity and consistency of crop growth, and thus is not easy to affect the overall grain yield.

The pushing member 402-43 is also fixedly connected to the bottom end of one of the second guide slide bars 401-12.

[0075] Furthermore, Fig.11 The telescopic member 402-42 includes a fixed sleeve 402-421 fixedly connected to the fixed rod 402-41, the fixed sleeve 402-421 has an open structure at one end facing the annular tube 402-2, and a movable rod 402-422 slides through the opening, a return spring 402-423 is fixedly connected to the inner end of the movable rod 402-422, the return spring 402-423 is fixedly connected to the inner bottom wall of the fixed sleeve 402-421, the outer end of the movable rod 402-422 is fixedly connected to the annular tube 402-2, and a movable groove 402-424 connected to the interior of the fixed sleeve 402-421 is provided on the inner side of the fixed sleeve 402-421.

[0076] like Fig.10 The pushing member 402-43 includes a cross bar 402-431 fixedly connected to the bottom end of the second guide slide bar 401-12, a vertical bar 402-432 fixedly connected to one end of the cross bar 402-43 away from the second guide slide bar 401-12, an oblique bar 402-433 fixedly connected to the bottom end of the vertical bar 402-432, a limit bar 402-434 fixedly connected to the bottom end of the oblique bar 402-433, and a connecting rod 402-435 fixedly connected between a pair of movable rods 402-422, the connecting rod 402-435 is adapted to slide with the moving groove 402-424, and a protrusion 402-436 is fixedly connected to the side of the connecting rod 402-435 facing the vertical bar 402-432, and the bottom of the protrusion 402-436 is an inclined surface, and the end of the inclined surface away from the hose 402-1 is higher than the end close to the hose 402-1.

[0077] When feeding, such as Figure 9-10 The inclined surface at the bottom of the protrusion 402-436 is movably fitted with the inclined surface at the top of the inclined rod 402-433, and the return spring 402-423 is in a natural state. When discharging, the end of the protrusion 402-436 away from the connecting rod 402-435 is in movably contact with the limiting rod 402-434, and the return spring 402-423 is in a stretched state.

[0078] The remaining structures are the same as those of Example 1.

[0079] In summary, when in use, when the second lifting plate 401-8 moves upward, the second guide slide bar 401-12 moves upward accordingly. Therefore, the second guide slide bar 401-12 can drive the cross bar 402-43 in the pusher 402-43 to move upward. The cross bar 402-43 drives the oblique rod 402-433 to move upward through the vertical rod 402-432. The oblique rod 402-433 can push the protrusion 402-436 to move in the direction of the annular tube 402-2 by cooperating with the bottom inclined surface of the protrusion 402-436. The protrusion 402-436 is pushed by the connecting rod 402-435. The movable rods 402-422 move, and the movable rods 402-422 push the ring tube 402-2 to move, so that the ring tube 402-2 can be set on the outside of the plant stem, and then the spray head 402-3 is evenly distributed around the plant stem, so that water and fertilizer can be sprayed around the stem for irrigation, and the irrigation uniformity is good, which can ensure that the nutrients in the soil are evenly distributed, so that it is not easy to produce deviations when the crop roots absorb nutrients, and it is not easy to affect the overall growth balance of the plant. In addition, with the quantitative irrigation of water and fertilizer in Example 1, it is not easy to over-irrigate, so it is not easy to cause root rot, root burn and other diseases.

[0080] When all the water and fertilizer in the metering cylinder 401-4 are discharged, the drive motor 302 drives the transmission shaft 303 to rotate in the opposite direction to the previous direction, so that the first lifting plate 401-7 and the second lifting plate 401-8 move downward along the screw rod 401-6, and the first lifting plate 401-7 and the second lifting plate 401-8 respectively drive the feed opening and closing piston 401-9 and the discharge opening and closing piston 401-10 to move downward until the feed opening and closing piston 401-9 is separated from the branch pipe 401-3, and the discharge opening and closing piston 401-10 is completely connected with the discharge pipe 401-5. At this time, the metering cylinder 401-4 can be replenished. , waiting for the next crop to be watered; in addition, when the second lifting plate 401-8 moves downward, the second guide slide bar 401-12 moves along with it, and the second guide slide bar 401-12 drives the limit rod 402-434 and the inclined rod 402-433 in the pusher 402-43 to move downward. When the inclined rod 402-433 is reset, the movable rod 402-422 is reset under the rebound force of the reset spring 402-432, thereby resetting the protrusion 402-436 and the ring tube 402-2, and then pushing the device to move, so that the opening of the ring tube 402-2 corresponds to the stem of the next plant, and this cycle repeats.

[0081] The specific method of using the above equipment for water and fertilizer irrigation for grain planting is:

[0082] S1: In the initial state, the feed opening and closing piston 401-9 is separated from the branch pipe 401-3, so that the water and fertilizer in the mixed storage barrel 201 can enter the branch pipe 401-2 through the connecting pipe 401-1, and then enter each branch pipe 401-3 from the branch pipe 401-2, and enter the metering barrel 401-4 from the branch pipe 401-3, and are temporarily stored in the metering barrel 401-4; through the cooperation of the handle 103 and the universal wheel 102, the equipment is moved to the grain planting site, and the universal wheel 102 is made to correspond to the gap between two adjacent rows of crops, and the universal wheel 102 rolls along the gap, which is convenient for moving the equipment and not easy to damage the plants during the movement.

[0083] S2: During specific use, the handle 103 and the universal wheel 102 are used to move the equipment to the grain planting site, and the universal wheel 102 is made to correspond to the gap between two adjacent rows of crops. Then, the position of the equipment is adjusted by the handle 103 so that the opening of the ring tube 402-2 corresponds to the stem of the plant. The purpose of this setting is to enable the ring tube 402-2 to automatically fit around the outside of the plant stem under various linkage effects when the discharge pipe 401-5 is opened, thereby providing conditions for irrigation around the plant.

[0084] S3: Start the drive motor 302, the output end of the drive motor 302 drives the transmission shaft 303 to rotate, the transmission shaft 303 drives the first gear 304 to rotate, the first gear 304 drives the double-sided rack 306 meshing with it to move, when the double-sided rack 306 moves, it drives the second gear 401-14 meshing with it to rotate, the second gear 401-14 drives the screw rod 401-6 to rotate through the rotating shaft 401-13, when the screw rod 401-6 rotates, the first lifting plate 401-7 and the second lifting plate 401-8 are respectively in the first Under the guidance and limiting action of the guide slide bar 401-11 and the second guide slide bar 401-12, the first lifting plate 401-7 and the second lifting plate 401-8 respectively drive the feed opening and closing piston 401-9 and the discharge opening and closing piston 401-10 to move upward. When the discharge opening and closing piston 401-10 is not completely separated from the discharge pipe 401-5, the feed opening and closing piston 401-9 is plugged into the bottom end of the branch pipe 401-3 to prevent water and fertilizer from entering the metering cylinder 401-4 during irrigation;

[0085] S4: Continue to drive the feed opening and closing piston 401-9 and the discharge opening and closing piston 401-10 to move upward through the driving motor 302 until the discharge opening and closing piston 401-10 is away from the discharge pipe 401-5. After the discharge pipe 401-5 is opened, water and fertilizer enter the ring pipe 402-2 through the hose 402-1, and then are sprayed to the surrounding side of the plant stem by the plurality of spray heads 402-3 at the bottom of the ring pipe 402-2;

[0086] S5: In addition, when the second lifting plate 401-8 moves upward, the second guide slide bar 401-12 moves upward accordingly. Therefore, the second guide slide bar 401-12 can drive the pusher 402-43 to move upward. During the upward movement of the pusher 402-43, the cooperation between the inclined rod 402-433 in the pusher 402-43 and the bottom inclined surface of the protrusion 402-436 can push the protrusion 402-436 to move. The protrusion 402-436 pushes the movable rod 402-422 to move through the connecting rod 402-435. The movable rod 402-422 pushes the annular tube 402-2 to move, so that the annular tube 402-2 can be sleeved on the outside of the stem of the plant, and then the water and fertilizer can be sprayed around the periphery of the stem;

[0087] S6: After all the water and fertilizer in the metering cylinder 401-4 are discharged, the drive motor 302 drives the transmission shaft 303 to rotate in the opposite direction to the previous direction, so that the first lifting plate 401-7 and the second lifting plate 401-8 move downward along the screw rod 401-6, and the first lifting plate 401-7 and the second lifting plate 401-8 respectively drive the feed opening and closing piston 401-9 and the discharge opening and closing piston 401-10 to move downward until the feed opening and closing piston 401-9 is separated from the branch pipe 401-3, and the discharge opening and closing piston 401-10 is completely separated from the discharge pipe 401-5. When the second lifting plate 401-8 moves downward, the second guide slide bar 401-12 moves along with it, and the second guide slide bar 401-12 drives the limit rod 402-434 and the inclined rod 402-433 in the pusher 402-43 to move downward. When the inclined rod 402-433 is reset, the movable rod 402-422 is reset under the rebound force of the reset spring 402-432, thereby resetting the protrusion 402-436 and the ring tube 402-2.
