Abstract

The invention discloses a method for rapidly preventing and controlling a desert sandstorm by using a biomass skinning technology. The method comprises the following steps that a water-soluble biomassglue is diluted and dissolved, is added with a flocculant to stirr, then is sprayed to the surface of sand. According to the method, enrichment of nutrient substances on the surface of the biomass-sand grain crust is carried out after fine-grained matter deposition and atmospheric micro-dust settling and accumulation, so that conditions are created for micro-soil biological breeding and low-gradeherbaceous plants colonizing, a good circulation of a desert ecological system is promoted, meanwhile, the method has the advantages of being simple and feasible, good in skinning effect, convenientto popularize, capable of selecting the biomass glue which is not eaten and is low in price, non-toxic, pollution-free, cannot damage the ecological environment and can be used in a wide range.

Description

technical field [0001] The invention relates to a method for quickly preventing and controlling sandstorms in deserts by using biomass crust technology, and belongs to the field of ecological environment protection. Background technique [0002] Sandstorm is the general term for sandstorm and dust storm. Sandstorm refers to the weather phenomenon in which the dust and sand on the ground are blown up by strong winds, making the air very turbid, and the horizontal visibility is less than 1km. It is the main symbol of desertification. According to historical records, during the 2154 years from the 3rd century BC to 1949, there were 70 sandstorms in my country, which occurred once every 31 years on average. , a large range of influence and other new trends. At present, the spatial law of dust storms in my country is that the west is more than the east, and the north is more than the south. They are mainly concentrated in the arid and semi-arid areas of Northwest my country and N...
