Abstract

The invention belongs to the technical field of saline-alkali soil improvement and particularly relates to a saline-alkaline soil improving agent. The saline-alkali soil improving agent is characterized by comprising the following raw materials in parts by weight: 10-15 parts of flue gas desulfurization wastes, 20-30 parts of mixed grass meal, 3-8 parts of compound microorganisms, 5-15 parts of sawdust, 6-15 parts of sweet clover root powder and 10-15 parts of kieselguhr, wherein the mixed grass meal consists of sainfoin, symphytum officinale, coronilla varia and festuca arundinacea, and the compound microorganisms consist of nitrogen-fixing bacteria, Bacillus subtilis, bacillus licheniformis and bacillus mucilaginosus. The improving agent disclosed by the invention not only can greatly and effectively improve the current situations of saline-alkali soil, but also can utilize wastes and recycle resources and ecological vegetation, and is environment-friendly, safe and free of secondary pollution problem.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali soil improvement, and in particular relates to a saline-alkali soil improvement agent. Background technique [0002] Saline-alkali soil is a type of soil formed by salinization or alkalization, including saline soil, alkaline soil and various saline-alkali soils. in drought [0003] And semi-arid areas, the salt contained in the bottom soil and groundwater, due to ground evaporation, with the capillary action of the soil [0004] The water containing salt rises to the surface layer. After the water evaporates, the salt remains on the surface of the soil and accumulates to form saline-alkali land. marina [0005] Due to the permanent seawater intrusion in the area, the saline-alkali land is widely distributed, the salt content is high, and too much soluble [0006] Sexual salts. The surface soil of saline-alkali land is mostly dry and white, and even forms salt crust, hardened and cracke...
