[0033] In the embodiment, the irrigation box 3 and the water storage box 4 are pointed at the lower side, which is convenient for inserting into the soil.

[0034] In the embodiment, the recycling cylinder 402 is provided with a one-way valve at the communication part with the excess box 401, so that the moisture in the recycling cylinder 402 enters the excess box 401 in one direction.

[0035] In the embodiment, the irrigation box 3 is uniformly distributed with through holes on the side wall near the crop 6, which is convenient for irrigation.

[0036] In the embodiment, the recycling cylinder 402 of the water storage box 4 is uniformly distributed with through holes on the side wall away from the crop 6, and the inner wall of the recycling cylinder 402 is provided with a one-way liquid guide film, so that the moisture penetrates into the recycling cylinder 402 through the one-way liquid guide film.

[0037] In the embodiment, when the device is used, the moisture utilization guarantee device 1 is laid on both sides of the crop 6, and the depth of the irrigation box 3 inserted into the soil is determined according to the depth of the root system distributed in the soil during the growth of the crop 6, so as to ensure that the moisture in the irrigation box 3 flows to the root part of the crop 6, and the root system of the crop 6 absorbs the moisture.

[0038] Before irrigation, the piston 16 slides to the lowermost end of the recycling cylinder 402 under the action of its own gravity. When the crop 6 is irrigated, the irrigation water pipe 2 supplies moisture to the irrigation box 3, and after the moisture penetrates into the soil, the moisture away from the root system of the crop 6 penetrates into the recycling cylinder 402 through the one-way liquid guide film on the side wall of the recycling cylinder 402. After the moisture in the recycling cylinder 402 submerges the second floating block 20, the second pulling rope 19 is tightened under the action of the second buoyancy 20 and the gravity of the piston 16, the spring 18 is compressed, the plug 17 is separated from the upper end port of the flow guide cavity 1601, the second floating block 20 drives the piston 16 to slide upward under the buoyancy, the moisture on the upper side of the piston 16 flows to the lower side of the piston 16 from the flow guide cavity 1601, and according to the formula P=F / S, the pressure on one side of the recycling cylinder 402 is greater than that on one side of the excess box 401 due to the gravity of the second floating block 20 and the piston 16, so that the moisture in the recycling cylinder 402 is pressed into the excess box 401 through the one-way valve.

[0039] After irrigation, as the crop 6 absorbs water and evaporation reduces soil moisture, water in the irrigation tank 3 continuously seeps into the soil around the root system of the crop 6 through the through-holes. The height of the first float 13 decreases as the water in the irrigation tank 3 decreases, the first pull rope 14 loosens, and under the tension of the tension spring 15, the first plug 10 separates from the baffle 701 inside the water regulating cylinder 7. Water pressed from the recovery cylinder 402 into the transition tank 401 enters the water regulating cylinder 7 through the horizontal pipe 9 and is discharged into the irrigation tank 3 through the drain hole 702. In the process of adding water, the first float 13 floats up and the first pull rope 14 is tightened again, and the first plug 10 seals the partition 701. Water in the soil area away from the crop 6 roots seeps into the recovery cylinder 402 for recycling, replenishing the water in the irrigation tank 3. Then, it seeps into the soil in the root distribution area of ​​the crop 6 through the through holes in the side wall of the irrigation tank 3 to irrigate the crop 6. That is, by using the combined action of the water storage tank 4 and the irrigation tank 3, water away from the root area of ​​the crop 6 is recycled and reused to irrigate the roots of the crop 6, thus achieving efficient use of crop water.

[0040] like Figures 4-5 As shown, crops are planted side by side. When the distance between adjacent crops in the same row is greater than half the width of the water utilization protection device 1, in order to further improve the crop water utilization efficiency:

[0041] Example 2: The irrigation tank 3, water storage tank 4 and connecting panel 5 of the water utilization device 1 are all set in a semi-circular shape to ensure that the two sets of water utilization devices 1 form a circular structure around the root distribution area of ​​the crop 6. In addition, a recovery cylinder 21 is fixed on the end cap 403. A condenser rod 22 is set inside the recovery cylinder 21. The condenser rod 22 is concentrically distributed with the recovery cylinder 21. Four connecting rods 23 are evenly distributed between the lower end of the condenser rod 22 and the inner wall of the recovery cylinder 21. One end of the connecting rod 23 is fixedly connected to the lower end of the condenser rod 22, and the other end of the connecting rod 23 is fixedly connected to the inner wall of the recovery cylinder 21.

[0042] In this embodiment, a solar panel is provided on the upper side of the end cap 403, and the solar panel is connected to the condenser rod 22 through a wire.

[0043] In this embodiment, the power generated by the solar panel drives the condenser rod 22 to work. When the moisture in the air comes into contact with the condenser rod 22, it is cooled and liquefied into water droplets, which then drip into the recycling cylinder 402. By recycling the moisture in the air, the efficiency of crop water utilization is further improved.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
