Desert treatment technology

Abstract

The invention discloses a desert treatment technology, and is characterized in that: sand and stones in desert are piled into square, bar or crisscross sand barriers and are compacted, and then cement paste or lime mortar is sprayed or smeared on the surfaces of the sand barriers so as to form hard concrete epidermal layer; then drought-enduring vegetative cover is planted between sand barriers; the sand barriers are built on the desert in the combination with building materials such as cement and lime by using natural resources sand and stones in desert, thereby having the functions of sand fixation, water retention, windproof performance, soil and water loss prevention, easy plant growth, and achieving the effects of long-term desert treatment at low cost; therefore, the invention is a simple, convenient and easy technology for desert treatment, which is capable of manual work and also mechanical construction.

Description

1. Technical field [0001] The invention discloses a desert control technology, which belongs to the technical field of desert control. 2. Background technology [0002] The current technologies for controlling desertification mainly include plant sand control, chemical sand control, mechanical sand control, solid sand control and water transport sand control, etc. Plant sand control is greatly affected by geography and climate; it is difficult to implement on a large scale; chemical sand control is Using airplanes to spray chemical organic matter on the surface of sand dunes is too expensive and is not conducive to plant growth; mechanical sand control uses straw to make grass grids on sand dunes to achieve the purpose of windbreak and sand fixation. The transportation of raw materials is difficult and the cost of treatment is high. The validity period is short; solid sand control is to use clay and various components to build small dams on the sand dunes, which is limited b...

[0002] The current technologies for controlling desertification mainly include plant sand control, chemical sand control, mechanical sand control, solid sand control and water transport sand control, etc. Plant sand control is greatly affected by geography and climate; it is difficult to implement on a large scale; chemical sand control is Using airplanes to spray chemical organic matter on the surface of sand dunes is too expensive and is not conducive to plant growth; mechanical sand control uses straw to make grass squares on sand dunes to achieve the purpose of windbreak and sand fixation. The transportation of raw materials is difficult and the cost of treatment is high. The validity period is short; solid sand control is to use clay and various components to build small dams on the sand dunes, which is limited by the geographical environment and is not convenient for construction; water flow sand control is to use the scouring effect of water to transport sand and stones To the designated place, its governance effect is greatly restricted by geographical conditions
