Halophilic and alkalophilic microorganism solid bacterial fertilizer of saline-alkaline habitat of desert and preparation method and application thereof

Abstract

The invention discloses halophilic and alkalophilic microorganism solid bacterial fertilizer of saline-alkaline habitat of desert and a preparation method and application thereof. The bacterial fertilizer comprises 100 weight parts of fermentation material, 1-3 weight parts of sulphur powder, 0.5-1.5 weight parts of zinc sulfate, and 0.5-1.5 weight parts of magnesium sulfate of which the water content is less than or equal to 20%, wherein the fermentation material is prepared by the following steps of: uniformly mixing and stacking 2-5% of drought desert halophilic and alkalophilic microorganism agent, 10-15% of water and 85-80% of organic material for fermentation, fermenting for 7-14 days when the fermentation temperature is 50-65 DEG C, and keeping for 10-20 days when the temperature of the fermentation stack is reduced to 45-55 DEG C. The halophilic and alkalophilic microorganism solid bacterial fertilizer of saline-alkaline habitat of desert disclosed by the invention can dissolve phosphate and nitrate in soil and release a great quantity of fixed phosphorus, potassium and trace elements stored in soil to improve the effectiveness of soil nutrients, and realizes nutrition supply and effective soil for permanent survival of the plant in the saline-alkaline habitat of desert.

Description

technical field [0001] The invention relates to the field of biological bacterial fertilizer technology and saline-alkali land treatment, in particular to a solid bacterial fertilizer of halophilic microorganisms in a saline-alkali desert environment, a preparation method and application thereof. Background technique [0002] Halo-alkali bacteria have survived and evolved in saline-alkali environment for a long time, forming some very special structures and physiological mechanisms, and can produce some unique metabolites. The related enzymes and special biologically active substances produced by it have important industrial value and have made great contributions to human beings. In the arid oasis area of ​​Northwest my country, saline-alkali land and saline-alkali flats account for 40% of the total land area. The groundwater level in this area is high, the soil is saline-alkali heavy and saline-alkali land is widely distributed. Rich resources of halophilic bacteria. [0...

AI Technical Summary

Problems solved by technology

In the past, there were also researches on various types of microbial saline-alkali soil amendments aimed at the problem of widespread distribution of saline-alkali land in my country and the lack of effective governance. It is well adapted to the saline-alkali habitat of the arid desert, let alone improving the saline-alkali land and improving the viability of plants
