Desert treating method

Abstract

The invention relates to a desert treating method. The method comprises following steps: mixing biological compound fertilizers, reinforced-processed mushroom-sticks, compound-fermented organic fertilizers and plant seeds according to the proportion and loading them into non-woven fabrics; utilizing a sewing machine to sew into flat soil-stabilizing belts, wherein trilateral or quadrangular grids with the largest side length ranging from 0.5 to 2m enclosed by the soil-stabilizing belts are arrayed continuously in a to-be-treated desert area and arranging fixing devices for fixing the soil-stabilizing belts according to wind power of the desert area; enabling humidity of the soil-stabilizing belts to suitable for germination of plant seeds by means of nature or rainwater and keeping humidity of the soil-stabilizing belts to be within the range for seed germination and growth; and forming grid units by the soil-stabilizing belts as basic soil-stabilizing units. The design of the non-woven fabrics can better store water and keep humidity. The biological compound fertilizers, the compound-fermented organic fertilizers and the reinforced-processed mushroom-sticks can provide sufficient nutrient compositions to plant seeds. The desert treating method is utilized so that desert treating efficiency is effectively increased and greening effect is improved. The desert greening stability in the late phase is good.

Description

technical field [0001] The invention relates to a method for controlling deserts. Background technique [0002] According to the national desert, Gobi and sandy land census and desertification survey results, China's desertified land area is 2.622 million square kilometers, accounting for 27.4% of the country's land area, and nearly 400 million people are affected by desertification. According to research on international cooperation projects between China, the United States, and Canada, the direct economic loss caused by desertification in China is about 54.1 billion yuan. Among the desertified lands in China, the area of ​​desertification caused by wind erosion is the largest, accounting for 1.607 million square kilometers. According to statistics, since the 1970s, only the expansion rate of land desertification has reached 2,460 square kilometers per year. [0003] Patent 200720084211.3 discloses a mesh belt, which is made of a bag with a water-permeable mesh sheet on o...

Problems solved by technology

However, the practical area of ​​the sand-fixing greening net involved in this utility model patent is small, that is, it can grow seedlings, and the area of ​​the grass seed fixing column that plays a greening role is small. When laying a large area, the utilization rate is low, which is not conducive to large-area greening.
