Abstract

The invention belongs to the field of desertification land crops planting technology and provides an improved desertification land method by utilizing a sand fixing adhesive material, which comprisesthe following steps of: uniformly mixing sand soil and fly ash according to a volume ratio of 1:3.6-4.2 to form a planting layer; the depth of the planting layer is more than 30cm, After thawing in spring, the jerusalem artichoke tubers are selected for sowing. 50-55kg tuber seeds are needed per hectare. The planting spacing is 0.5*0.5 and the seeding depth is 10-20cm. the carrot seeds are sown after the jerusalem artichoke is sown 160-170 days and the jerusalem artichoke rod is removed for 30-35 days after the carrot is sown. The sand fixing adhesive material solves the problem of difficult planting on the desertification land in the prior art.

Description

technical field [0001] The invention belongs to the technical field of desertification land control, and relates to a sand-fixing adhesive material and a method for improving desertification land. 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 the research of international cooperation projects between China, the United States and Canada, the direct economic loss caused by desertification in China is about 54.1 billion RMB. The desertification land treatment method in the prior art has the problem of poor treatment effect, and the land after treatment cannot meet the needs of crop growth. Contents of the invention [0003] The invention provides a sand-fixing adhesive material and a method for improving des...
