Method for sand prevention and binding and greening with coverlay

Abstract

The invention relates to a covering film preventing sand and virescence method, which is that laying reentrant plastic covering film preventing sand in sand trough wall, fully burying sand in the covering film so that one end of the covering film, with 30-50kg force per square meter, is fixed in sand, setting several of cuts on the covering film, planting herb applied in sand or shrub with economic value in cuts. The covering film is not oxidized for 10-30 years and low cost. It not only prevents sand flowing in explicit sand zone but also sand winding in intrinsic sand zone and sand weather forming. It is the efficiency means that widely and drastically curing soil desertification and sand moving.

Description

technical field [0001] The invention relates to a sand-proof and sand-fixing cover, specifically, a cover film of plastic material is covered on the sandy ground of the subdued sand belt or the open sand belt, so as to prevent strong wind from blowing sand or yellow sandy soil and prevent sandy weather. Formation, the present invention also relates to planting grass or planting shrubs at openings on the covering film to achieve sand-fixing effect, and especially relates to a covering film preventing sand and fixing sand and its greening method. Background technique [0002] Desert geological natural disasters are the only natural disasters that threaten human survival. With the increase of population and the development of agriculture and animal husbandry, due to the indifference of people's awareness of environmental protection, large areas of vegetation in the sand belt are eaten up by livestock. , in particular, the trees on the loess belt that can block the movement of q...

Problems solved by technology

In order to control natural disasters in desert areas, trees are artificially planted and plants are planted to prevent and fix sand. The sand control and greening method of sand barriers in Shapotou, which has been promoted, prevents quicksand from threatening roads and railways and plays a good role. effect, this method can only be applied to small areas of desert areas

[0003] The surface anti-sand, sand-fixing and dust-proof agent announced by the State Intellectual Property Office of China and its preparation method and application method, patent announcement number: 1200993, uses a mixed solution containing polyvinyl alcohol, boric acid, lauryl ammonium chloride and water, Spray on the sandy soil surface of the bright sand belt, so that a thin layer of film is formed on the sandy soil surface to prevent the sand from flowing. However, in the event of a storm above level 8, for example, a child weighing about 30 kg on the bright sand belt will also be killed. Blow away, this spray will cover the surface of the sand, it will be blown to pieces by the wind, and lose the use of sand fixation
