Method for performing water retention and wetting irrigation by use of horizontal water storage tanks with contour line and structure

Abstract

The invention relates to a water-retention wetting irrigation method, particularly relates to a method for performing water retention and wetting irrigation by use of horizontal water storage tanks with a contour line and also relates to specific structures of the horizontal water storage tanks with the contour line. The method comprises the following steps: (1) excavating the horizontal water storage tanks along the contour line of a slope, wherein each water storage tank is vertical to the runoff direction of the slope; (2), backfilling filler into the excavated water storage tanks, wherein the water storage grooves are full of the filler which is flush with the original slope; (3), planting grass on the slope between the adjacent water storage tanks. The method has the advantages that water from the slope can be favorably stored, a runoff water head can be dispersed, and waterflow impulse force can be decelerated, so that the waterflow is effectively intercepted and infiltrates into the ground, and the effects of absorbing meteoric water and regulating and storing the overland runoff are realized.

Description

technical field [0001] The invention relates to a method for water retention and infiltration irrigation, in particular to a method for water retention and infiltration irrigation using a contour horizontal water storage tank, and also relates to a specific structure of the contour horizontal water storage tank. Background technique [0002] In order to solve the international problem of water resource shortage, new irrigation technologies such as sprinkler irrigation, drip irrigation, and infiltration irrigation are widely used in agricultural production. These technologies have obvious water-saving effects. However, these technologies have high requirements for water sources and water quality, and require stable water sources. , and the investment in equipment is large, the management is difficult, and it is not suitable for large-scale promotion in deserts that lack water, have no power, and are arid and semi-arid. In addition, these technologies do not yet have the abi...

AI Technical Summary

Problems solved by technology

However, these methods also have the following problems: 1. In the process of raining, many branches, waste, and solid matter enter the irrigation system with the runoff through the water delivery system of the catchment surface, causing blockage of the channel, making the diversion and drainage unsmooth, and need to be removed in time Waste in rainwater; 2. The ability to resist strong rain runoff is limited. These irrigation technologies are open ditch fixed projects, and the interception ability is limited when irrigation water is injected or rainfall runoff enters. and soil erosion; 3. The efficiency of preventing invalid evaporation is not high. In order to prevent water storage in the pit and soil water from ineffective evaporation, and to prevent root system frostbite in winter, the pit mouth is covered with long straw, which is easy to damage, has a short service life, and is easy to be stored by people. Destruction; 4. The utilization rate of rainwater collection and storage is not high
