Soil amendment for improving saline-alkali soil

Abstract

The invention relates to a soil amendment, prepared from an aqueous suspension agent component and a microbial component, wherein the aqueous suspension agent component is prepared from montmorillonite and activated clay, and the microbial component is prepared from bacillus licheniformis, bacillus subtilis, pichia pastoris, chromatium okenii and bacterial powder of streptomyces microflavus. Before use, the aqueous suspension agent component is mixed with the microbial component, and the effective living bacteria numbers of all the bacteria in the obtained suspension are more than or equal to 1.00* 10<9> / ml. The soil amendment can be used for improving saline-alkali soil so as to enable the saline-alkali soil to be suitable for plant growth. Furthermore, the soil amendment also has good capacities of water retention and fertilizer maintenance. After the soil amendment provided by the invention is applied into the soil, the total number of organic matters and microorganisms is remarkably increased, the soil quality is improved, the soil is prevented from hardening, and the soil amendment is beneficial to the sustainable development of the soil.

Description

technical field [0001] The invention relates to the field of soil improvement, more particularly, to a soil conditioner. Background technique [0002] The salinization of land is a worldwide ecological problem. At present, the degree of salinization of land in the world shows an obvious upward trend. Under the effects of climate warming, reduction of surface fresh water resources, rise of groundwater level and unreasonable irrigation, soil salinization is becoming more and more serious. The area of ​​saline soil in my country is about 34.6 million hectares, and 7.6 million hectares of cultivated land are salinized. Nearly one-fifth of the cultivated land is salinized. The improvement of salinity is conducive to the sustainable and healthy economic development of my country's inland arid areas and coastal areas. Land management, The protection of the ecological environment is of great significance. So far, a series of measures such as water conservancy improvement, physical ...

Problems solved by technology

However, some of these methods are time-consuming and laborious, some are costly, and some require a large amount of water flooding, which wastes a large amount of water resources, especially in some areas where fresh water resources are relatively scarce, it is even more undesirable

Biological improvement of saline-alkali soil, especially the use of soil improvers containing microorganisms is a sustainable method. However, the soil improvers on the market have a single strain of bacteria, a single problem to solve, complex production processes, and product bacteria. The problem of low activity and low survival rate
