Method for afforesting desert and retaining water

Abstract

The invention relates to the field of ecological environment protection, in particular to a method used for afforesting a desert. The method used for afforesting the desert comprises the following steps of: 1, excavating a filling slot; 2, paving a waterproof impervious layer; 3, paving a sand layer; 4, paving a plant growing layer; and 5, paving a straw plaited grid. The waterproof impervious layer is arranged in the sand layer, the waterproof impervious layer stops flow direction of water, and water can not leak everywhere deep in the sand layer, thus the aim of saving water is achieved; the used material is environmentally friendly, and human and natural environment can not be polluted; water supply is reasonable, water can be uniformly supplied to plants used for afforesting, the plants can rapidly grow, and the problems of water for afforesting the desert and rainwater seepage control can be effectively solved. The method has a wide application field and is convenient for standardization construction. By applying the method to afforest the desert, a conditioned desert can be afforested, desert vegetation coverage rate can be improved, and a local ecological environment of the desert can be improved.

Description

technical field [0001] The invention relates to the field of ecological environment protection, in particular to a method for desert greening. Background technique [0002] Due to incorrect human activities around the world, the earth is warming, desertification is intensifying, and sandstorms are becoming more and more serious. The annual losses caused by sandstorms in China are as high as more than 50 billion RMB, which directly affects the survival of more than 400 million people. Sandstorms cause the deterioration of the human living environment, desertification leads to the reduction of land in desert areas, the decline in productivity, and the decline in the quality of grasslands. Land desertification leads to regional economic poverty People in desert areas cannot get rid of poverty, cannot attract business and investment, and lack economic growth points, which restricts the development of my country's economy. The economic losses caused by desertification are no less ...

Problems solved by technology

[0003] In order to effectively control desertification, change the local ecological environment of the desert, and control sand damage, planting grass and greening on the desert surface is a very effective treatment method. However, desert greening is extremely difficult, and many people are looking for an effective greening method. However, it is very difficult to achieve the effect of greening and governance. At present, the methods for greening deserts include: mainly using soil and stones to bury the sand layer. This method is extremely expensive and cannot be used in most areas; there is also the use of grass grids To fix sand, this method is time-consuming and labor-intensive, and the life is very short; the other part uses chemical methods to fix sand, using asphalt and plastic products to fix sand. This method wastes a lot of energy and resources on the one hand, and causes environmental damage. pollution, and the third is short lifespan, which cannot solve the fundamental problem

Another problem is greening in the desert. The water will seep irregularly into the sand layer immediately, and the waste of water is very serious. To solve the above problems, we have invented a multi-layer water barrier for desert greening. Water-blocking and anti-seepage layer material and its application method
