Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] The present invention sends water into a porous medium layer 4 buried under the soil layer 2, and then makes the water in the porous medium layer 4 penetrate into the soil layer 2 gradually through capillary action, thereby maximizing the utilization of irrigation water.

[0030] As shown in Figure 1, a trench 9 is excavated on the ground 1. The width of the trench 9 is generally 1 to 1.5 meters, and the depth is 0.4 to 0.8 meters. Trapezoidal is preferred.

[0031] As shown in Figure 2, the anti-seepage layer 5 is laid at the bottom of the trench 9, and the anti-seepage layer 5 can adopt various materials and forms, such as weakly permeable water-based clay, plastic cloth, cement, etc.; The porous medium layer 4 is buried, and there are anti-seepage layers 5 under and on both sides of the porous medium layer 4 . There are also many materials a...

Abstract

The present invention discloses one kind of water saving irrigation method and the set therefor. Water is first fed to the porous medium layer below the planting soil layer in the pressure of 0.01-0.1 MPa and then permeated by means of capillary action to the planting layer. The water saving irrigation set includes water pipe with water outlet pores in the wall set in the porous medium layer, antiseepage layers below and beside the porous medium layer and soil layer, all in a groove. Compared with available technology, the present invention has the advantages of no evaporation and leakage, simplicity, high water saving effect, low cost, etc.

Description

technical field [0001] The invention relates to the technical field of irrigating plants planted in soil, in particular to a water-saving irrigation method and a device for realizing the method. Background technique [0002] Irrigation water from water source to field, to being absorbed by crops and forming yield mainly includes four links: water resource allocation, water transportation and distribution, field irrigation and crop absorption. Take corresponding water-saving measures in each link to form a complete water-saving irrigation technology system, including water resources optimal allocation technology, water-saving irrigation engineering technology, agronomic and biological water-saving technology and water-saving management technology. Among them, water-saving irrigation engineering technology is the core of the technical system. [0003] At present, water-saving irrigation engineering technologies mainly include channel anti-seepage technology, pipeline water de...
