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, pa...

Embodiment Construction

[0024] In Fig. 1, the cover film (3) of sand prevention and sand fixation adopts a kind of high tensile strength, oxidation resistance, and the plastic material of non-polluting environment is cover film (3), and its thickness is 0.04 millimeter, and every ton of cover film ( 3) 17,000 square meters of sandy ground can be laid.

[0025] 1, its structure of said covering film (3) sand-proofing and sand-fixing effect of the present invention is by following embodiment:

[0026] a. Use a bulldozer to flatten the protruding sand dunes in the buried sand belt or open sand belt without vegetation, and excavate a sand ditch (2) with a depth of 40 cm and a width of 25 cm with manual or mechanical excavation. The distance between each sand ditch The distance is 4 meters.

[0027] b. Lay the looped cover film (3) on the sandy soil (1) ground, and lay the cover film (3) along the wall of the sand ditch (2) into a concave cover film (4) at the sand ditch (2), Fill the concave cover film...

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...
