Microbial bacterium fertilizer aiming at soda salinization saline-alkali soil and preparation method of microbial bacterium fertilizer

Abstract

The invention is applicable to the technical field of saline-alkali soil improvement and provides a microbial bacterium fertilizer aiming at soda salinization saline-alkali soil and a preparation method of the microbial bacterium fertilizer. The microbial bacterium fertilizer comprises the following components in parts by weight: 5-15 parts of mineral powder, 20-25 parts of humic acid, 8-15 partsof magnet tailing powder, 2-8 parts of a chemical improvement agent, 5-15 parts of an acidic conditioner, 15-35 parts of organic fertilizers, 10-25 parts of inorganic complex fertilizers and 5-15 parts of a biological bacterium agent. Therefore, the microbial bacterium fertilizer disclosed by the invention can achieve the effects of effectively improving the soil fertility of the soda saline-alkali soil and improving the yield of crops.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a microbial fertilizer for soda salinization and saline-alkali land improvement and a preparation method thereof. Background technique [0002] The western part of the Songnen Plain is the concentrated distribution area of ​​soda saline-alkali soil in my country. The area of ​​saline-alkali land exceeds 50 million mu. The increasing soil salinization has made the ecology of this area increasingly fragile, and salinization control is imminent. Practice has proved that saline-alkali soil can become a valuable cultivated land resource after transformation, so it has also become a potentially precious reserve land resource in our country. The traditional control of saline-alkali land mainly includes water conservancy projects. The purpose of reducing soil salinity is achieved through irrigation and drainage. However, salinized areas are often areas where fresh ...

Problems solved by technology

The traditional control of saline-alkali land mainly includes water conservancy projects. The purpose of reducing soil salinity is achieved through irrigation and drainage. However, salinized areas are often areas where fresh water resources are scarce, limited by water resources, and the texture of soda saline-alkali soil is heavy. The effect of washing salt with water Not ideal; the physical measures are mainly guest-soil methods, that is, selecting the nearest aeolian soil for surface soil replacement or rebuilding the surface soil. This method has quick results, but the project is huge, the soil source is scarce, the cost is too high, and the implementation is difficult; chemical measures The main method is to apply various improvers. This method has a certain effect on mildly saline-alkali cultivated land, but it has poor persistence and needs to be applied repeatedly. However, limited improvers on medium-to-severely saline-alkali land are not suitable for higher salinity in the soil. Alkali is simply a drop in the bucket, and it is difficult to achieve the improvement effect

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
