Embodiment 1

[0070] The method of using the wind-sand hazard prevention and control protection belt in the extremely arid desert area includes the following steps:

[0071] A. Preparation of restoration mixture

[0072] The mixed soil is not crushed, and additives and fertilizers are added to the mixed soil and mixed evenly. The mixed soil is prepared by the following parts by weight: 90 parts of mixed soil, 5 parts of additives, the mixed soil includes loess, the additive is carboxymethyl cellulose, and the fertilizer is Animal manure, potash, phosphorus and nitrogen fertilizers;

[0073] B. Prepare sand barrier inner core

[0074] The upper quicksand of the dune is directly piled into the inner core of the sand barrier of the hollow cylinder; the cross section of the hollow cylinder is quadrilateral;

[0075] C. Cover the shell of the sand barrier

[0076] Mixed soil covers the inner core of the sand barrier to form a desertification environment restoration mixed soil sand barrier, th...

Abstract

The invention relates to the technical field of desert remediation, in particular to a wind-sand damage prevention and control protection zone in an extremely dry desert area and a use method thereof.The wind-sand damage prevention and control protection zone adopts raw materials which are widely available, low in cost, strong in binding force, capable of bringing nutrition elements for plant growth and the like, and is very suitable for composite use with plants for sand fixation. In addition, a sand-fixing method with mixed soil can easily achieve mechanization, and can be adjusted according to local conditions. Sand-fixing patterns are flexibly varied and the advantages of sand barriers of different geometric shapes can be exerted.

Description

technical field [0001] The invention relates to the technical field of desert restoration, in particular to a protective belt for prevention and control of wind and sand hazards in extremely dry desert areas and a method for using the same. Background technique [0002] There are many methods of windbreak and sand fixation, currently the main applications are grass grid sand fixation, chemical sand fixation, polymer material net sand fixation, various large straw sand fixation, clay sand fixation, gravel sand fixation, plant sand fixation, etc. In order to effectively fix quicksand and restore the ecological environment, multiple sand-fixing methods are often used in combination. Due to the secondary pollution to the environment, chemical sand fixation and polymer material net sand fixation are not popularized. Grass grids and plant combinations are the most widely used sand fixation measures, but in recent years, due to the lack of grassland materials and the impact of mec...
