Problems solved by technology

However, almost all corn varieties are not resistant to salt and alkali, and the survival rate of corn in saline-alkali soil is low, and the harvest is not good. At present, it is still difficult to plant maize in saline-alkali soil

Abstract

The invention provides a microbial agent suitable for planting corn in saline-alkali soil. Then, the compound bacteria powder is mixed with the premix made of corn stalk powder, mushroom slag, cotton meal, etc., and then anaerobically fermented to obtain the fermentation material, and then the fermentation material is poured into polyaspartic acid, polyethylene The prefabricated material is obtained from the coating material made of alcohol aqueous solution, etc., and finally polycaprolactone is added to the prefabricated material and stirred to obtain a mixture, and then activated sludge is added to the mixture, and aerobic fermentation is obtained to obtain a microbial agent. After entering the saline-alkali soil, it can improve the physical and chemical properties of the soil, meet the nutritional needs of corn growth, and increase the yield of corn.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to a microbial bacterial agent suitable for planting corn in saline-alkali soil and a preparation method thereof. Background technique [0002] my country's per capita land area is far behind the international per capita land area level, so it is particularly important to develop and utilize the existing saline-alkali land. In China, saline-alkali land accounts for more than 10% of the cultivated land area. Saline-alkali land refers to the soil ecological environment with a salt content greater than 0.3% and a pH value greater than 8. Such soil environments almost all have low organic matter content, low nitrogen content, and available phosphorus content. Low, low effective moisture content, poor soil aggregate structure, decreased soil permeability, inhibited microbial flora activity, low soil temperature in spring and autumn and high in summer, not only hinders the a...
