System and method for treating gobi through modified sand of composite forest belt

Abstract

The invention discloses a system and method for treating gobi through modified sand of a composite forest belt. The method comprises the steps that the periphery of an enclosure breeding area is selected as a planting area of the composite forest belt; in late autumn, planting pits are dug in the direction vertical to a prevailing wind direction; in late spring and early summer of the next year, with assistance of natural wind power, the planting pits are filled with sand accumulation layers, water is introduced into the planting pits for irrigation, and sludge in the drainage process is mixed with accumulated sand in the planting pits to form silt soil; in late autumn, after moisture in the planting pits is reduced through evaporation, nursery stock transplantation or sowing of plant seeds is conducted, in the transplantation or sowing process, the peripheries of nursery stock roots and plant seeds are wrapped by the silt sand, and the accumulated sand covers the surfaces of the nursery stock roots and plant seeds; after planting is completed, irrigation is conducted again, and after water layer sedimentation does not exist on the surface layers, the surface layers are sprayed with a sand fixing agent. According to the system and method, by using natural and manual conditions of the enclosure breeding area, by planting the composite forest belt, the gobi environment is gradually improved, and the growth environment of a farmland network of the periphery of the gobi is well guaranteed.

Description

technical field [0001] The invention relates to the technical field of engineering wind and sand protection, and more specifically relates to a system and a method for controlling Gobi by using compound forest belts to modify sand bodies. Background technique [0002] The Gobi Desert is one of the huge desert and semi-desert regions in the world. It stretches across the vast land of Central Asia and spans the vast space of Mongolia and China. The vast desert and semi-desert flat land in the northwest of the Yanchi line. Several major and large deserts and sandy lands in China are mainly located in Xinjiang, Inner Mongolia, Gansu and Ningxia. The total area of ​​deserts (including sand dunes and wind-eroded land) is 712,900 square thousand The total area of ​​Gobi is 569,500 square kilometers, accounting for 13.36% of the country's total area. Among them, the total area of ​​Xinjiang desert is 420,000 square kilometers, and the Gobi area is 293,000 square kilometers, ranking ...

AI Technical Summary

Problems solved by technology

[0003] The Gobi area is generally relatively open, the soil is barren, the soil organic matter content is low, the fertility is low, and the wind is strong, carrying a large amount of sand and fine stones in the wind, which has a strong impact on plants, making it difficult for plants to survive. Abundant light resources and strong soil permeability have certain utilization value. In recent years, a large number of red dates and wolfberries have been planted in the Gobi area to maximize the use of resources. There is no other better way to fully utilize the Gobi governance, resulting in local The variety of crops is single, which does not meet the requirements of diversified development, and because of the height of jujube trees, it cannot well block the flying sand in the Gobi
