Abstract

The invention discloses a desert control method of a chemical sand-fixing greening technology based on organic composite materials, and the desert control method is characterized in that hydrophilic polyurethane resin curing agent solution is sprayed on a sand or soil layer of greening objects for sowing the vegetation for forming a porous fixed sand layer. The fixed sand layer formed by the method has appropriate thickness and strength, good durability, good anti-freeze and melt properties and functions of water retention, thermal insulation, ventilation, vegetation and the like. According tothe method of the invention, the stable and effective solidifying can be carried out on sand even under the specific desert environments of no abundant groundwater sources and strong wind erosion, and the purpose of vegetation greening can be also realized. The method has large-scale construction properties and good economic performances, thereby being applicable to the needs of large-scale chemical sand fixing and vegetation greening of the vast desert and realizing the plant greening function and the ecological restoration and the control of desertified land.

Description

technical field

[0001] The invention relates to a desert control method, in particular to a desert control method of chemical sand-fixing greening technology, which can be used for environmental control and ecological restoration of desertified land. Background technique

[0002] The desertified land on the world's land accounts for about 30% of the total land area, and the desertified area continues to expand with the continuous destruction of the environment and frequent human activities. On the other hand, the world's population continues to increase, and the per capita land area continues to decrease, and mankind will face a serious food crisis. In order to avoid this kind of crisis, it is very necessary for human beings to protect the land and manage the land that has been destroyed and gradually desertified, so as to restore its ecosystem and land functions.

[0003] Desertification refers to land degradation caused by various natural and man-made reasons such as clim...
