Preparation method of sandy soil conditioner for gobi deserts

Abstract

The invention discloses a preparation method of a sandy soil conditioner for gobi deserts, and belongs to the field of preparation of soil conditioners. The sandy soil conditioner for gobi deserts comprises the following raw materials in parts by weight: 40-50 parts of sodium bentonite, 6-10 parts of composite microbial agent, 10-16 parts of humic acid, 15-25 parts of rice husk carbon, 13-19 partsof kaolin, 4-6 parts of a bulking agent, 5-13 parts of a water-retaining agent, 2-5 parts of a nutritional supplement, 0.8-1.3 parts of compound amino acid and 2-4 parts of plant cellulose. The preparation method is simple, easy to operate and low in production cost; the prepared sandy soil conditioner is rich in soil nutrients, high in water retention and fertilizer storage capacity and remarkable in improvement effect on the sandy soil aggregate structure of the gobi desert; and the problems that existing sandy soil of the gobi desert is loose in particle, high in flowability and weak in interaction force among particles, and under the action of external force such as water power, gravity and wind power, land resources and land productivity are easily damaged, and the land surface is eroded and water loss is serious are solved.

Description

technical field [0001] The invention relates to the technical field of soil improver preparation, in particular to a method for preparing a sandy soil improver used in Gobi Desert. Background technique [0002] The Gobi Desert is located in the middle of the Mongolian Plateau. With the Gobi Desert as the boundary, the Mongolian Plateau is divided into Mobei and Monan Mongolia. Since the Qin Dynasty in ancient times, it has been called "the desert" and "the vast sea" in the history books of Chinese characters. The Gobi Desert is also the Mongolian Empire. The hometown of the Huns and Turks was also an active place. [0003] The sandy soil in the Gobi Desert has loose particles, strong fluidity, and weak interaction between particles. Under the action of external forces such as water, gravity, and wind, it is easy to damage land resources and land productivity, resulting in land surface erosion and water loss. Seriously, therefore, it is of great significance to improve the a...
