Embodiment 1

[0024] Such as Figure 1 to Figure 5 Shown: Agricultural water-saving irrigation circulation system, including anti-seepage mechanism, ventilation mechanism for ventilation of crop roots and drip irrigation mechanism for irrigating cultivated land 1, anti-seepage mechanism includes water collection unit and several anti-seepage units, several Two anti-seepage units are arranged side by side, and each anti-seepage unit all includes anti-seepage film 3, drainpipe 4 and foundation pit 2 excavated on the cultivated land 1 (the area that needs to cultivate crops), and the foundation of every adjacent anti-seepage unit The distance between the pits 2 is equal, the foundation pit 2 is an inverted trapezoidal pit, and the depth of the foundation pit 2 is determined according to the depth of the roots of the crops. The inner side walls of the pit 2 are against each other, and the drain pipe 4 is placed at the bottom of the foundation pit 2 and at the top of the anti-seepage membrane 3....

Embodiment 2

[0038] Such as figure 1 and image 3 Shown: the difference between the present embodiment and embodiment 1 is that the ventilation mechanism also includes a blower 13 and an air inlet pipe 15, and one end of the air inlet pipe 15 is communicated with the water collecting pipe 6, and the other end of the air inlet pipe 15 is connected with the outlet of the air blower 13. The air end is connected, and the air inlet pipe 15 is provided with a second valve 14 .

[0039] The implementation mode of this embodiment is: when there is no water in the drain pipe 4 and the water collecting pipe 6 or after the irrigation period of the crops has passed, the farmers can open the second valve 14 and start the blower 13. After the blower 13 is started, it will pass The air inlet pipe 15 blows air into the water collection pipe 6, and the wind entering the blow pipe enters the drain pipe 4 of each anti-seepage unit respectively, and then discharges from both ends of the vent pipe 7, and real...

Abstract

The invention belongs to the technical field of agricultural irrigation, and particularly discloses an agricultural water-saving irrigation circulating system which comprises an anti-seepage mechanism, a ventilation mechanism and a drip irrigation mechanism, the anti-seepage mechanism comprises a water collecting unit and a plurality of anti-seepage units, and the anti-seepage units are arranged side by side; each anti-seepage unit comprises an anti-seepage film, a drainage pipe and a foundation pit excavated in the cultivation land, the anti-seepage film is laid at the bottom end of the foundation pit, the edge of the anti-seepage film abuts against the side wall of the foundation pit after being turned over, the drainage pipe is arranged at the bottom end of the foundation pit and located at the top end of the anti-seepage film, and a plurality of water seepage holes are formed in the drainage pipe; the drainage pipe is wrapped and wound with a filtering assembly for blocking soil, one end of the drainage pipe penetrates through the impermeable film and communicates with the water collecting unit, the other end of the drainage pipe communicates with the ventilation mechanism, and the water collecting unit is used for supplying water to the drip irrigation mechanism. Irrigation water permeating into the ground can be collected and repeatedly irrigated, so that water resources are saved, and the tension situation of agricultural irrigation water is relieved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an agricultural water-saving irrigation circulation system. Background technique [0002] The proportion of agricultural water use in my country is very large. In 2018, the total agricultural water use in the country was 369.3 billion cubic meters, accounting for 61.4% of the total national water use. However, the efficiency of agricultural irrigation water is generally not high, and the efficient water-saving irrigation rate Only about 25%, far below the international advanced level. In order to increase the rate of water-saving irrigation, the Ministry of Water Resources will successively formulate irrigation water quotas for major crops such as grain, cotton, oil, sugar, fruit trees, vegetables, pastures, etc. It provides an important basis for volume allocation, water resources demonstration, water intake permit approval, water conservation evaluation, irrigat...
