An ecological sand control method

Abstract

The invention relates to an ecological sand control method. The method comprises the following steps: 1) putting 1-2 parts of an organic flocculating agent by weight and 1-2 parts of a gel water-retaining agent by weight into 20-100 parts of water in sequence, stirring and blending; 2) putting smashed and screened 2-3 parts of sludge by weight, 2-3 parts of stalks by weight, and 10-15 parts of sandy soil by weight which is taken on the spot and is smashed and screened to the mixture prepared in the step 1); 3) pouring products of the step 2) into a container, stirring and blending, using a mortar pump to convey the product to a forming mould, and forming at temperature of 40-60 DEG C; 4) after a culture medium is formed and demolded, conveying the culture medium to a place whose sandy soil needs improvement through a production line, and putting sandy plants in order on the spot and transplanting the sandy plants. The ecological sand control method makes plants be able to use water and nutrient substances in the culture medium to keep growing, root systems of the plants would be expanded with growth, so as to play a sand stabilizing effect and control sandy soil. The ecological sand control method can perform mechanized construction, and is simple and rapid and is pollution free.

Description

technical field [0001] The invention relates to an ecological sand control method. Background technique [0002] The irrational activities of human beings and the continuous deterioration of the earth's ecological environment, especially the problems of deserts, sandstorms and desertification, have seriously affected and threatened the survival of human beings and the sustainable development of economic society. In recent years, sandstorms have occurred frequently all over the world, and desertification has become more and more serious. It has become the number one enemy that threatens the survival and development of human beings. How to eradicate deserts, sandstorms, and desertification is a topic of the times and an urgent task in front of mankind. [0003] At present, the commonly used technologies for sand fixation mainly include engineering (or physical, mechanical) sand fixation, biological sand fixation, chemical sand fixation and comprehensive sand fixation.

Problems solved by technology

However, some chemical sand-fixing materials are likely to cause secondary pollution

[0007] Various single sand fixation measures have their own characteristics and limitations. Although engineering sand fixation is fast and effective, it is costly and has poor compatibility with organisms and the environment. Although biological sand fixation has a good effect on ecological environment protection, it is the most ideal sand fixation method. , but due to the harsh climate and hydrological conditions of deserts or sandy land, plants usually cannot be planted or cannot survive after planting; although chemical sand fixation is low in cost, fast and convenient in construction, and has good biocompatibility, the sand fixation cycle is usually short
