Sand water-soil conservation method

Abstract

The invention discloses a sand water-soil conservation method. The sand water-soil conservation method includes the following specific steps that 1, the top of a fixed dune or hillside is treated to be smooth, a water storage tank is arranged, and the slope surface is transformed into a step shape; 2, water pipes are connected on the water storage tank, and the water pipes are laid downwards alonga platform and a slope from the top and extends to the flat ground; 3, plants are planted at the top and the platform; 4, river bottom sludge is laid at the flat ground, licorice-root medicine residues, clay, plant ash, organic matter and the river bottom sludge are stirred to be even, a transformed soil layer is obtained, and anti-dry plants are planted on the transformed soil layer. According to the sand water-soil conservation method, sand is transformed with various methods, through synergistic effects of means of transforming a landform, arranging the water storage tank, the water pipes,water distribution pipes and water outlets and planting different plants at different positions, the capacity of adapting plant growth of soil can be improved, the recovered rate and the success rateare increased, the water-holding capacity of soil is increased, and water and soil loss is reduced.

Description

technical field [0001] The invention relates to the field of soil and water conservation, in particular to a method for soil and water conservation in sandy land. Background technique [0002] Land includes the atmosphere, soil, basic geology, hydrology, plants, and animals on the surface of the earth and above and below it, as well as the various results of past and present human activities in this area. The important influence exerted is a natural complex including many natural elements such as geology, landform, climate, hydrology, soil, vegetation, etc. in a certain section of the earth's surface. The land desertification in our country is serious, and the sandy land area accounts for about 3% of the land area and is expanding at an increasing speed. Sandy land refers to the area where the surface is covered by dunes (or sand), usually dominated by fixed or semi-fixed dunes, with a semi-arid or semi-humid climate, windy, little water flow, and less vegetation.

AI Technical Summary

Problems solved by technology

[0003] The biggest problem in sandy land is water and soil erosion, which greatly affects the planting of vegetation. The vegetation system is very fragile, and it is extremely difficult to recover naturally. At present, people's method of water and soil conservation in sandy land is to increase the vegetation coverage rate. However, sandy land The precipitation is small, the evaporation is large, the problem of vegetation irrigation is difficult to solve, and the root system of vegetation is underdeveloped, so it is difficult to play the role of maintaining water and soil

Moreover, it is difficult to maintain water and soil only by using a single means of increasing vegetation coverage.
