Microbial agent for solving physiological disorder problems of plant roots and preparation method of microbial agent

Abstract

The invention provides a microbial agent for solving physiological disorder problems of plant growing roots and a preparation method of the microbial agent. The microbial agent for solving the physiological disorder problems of the plant growing roots includes a secondary bacterial liquid of pseudomonas fluorescens, a secondary bacterial liquid of bacillus subtilis, a secondary bacterial liquid ofbacillus licheniformis, monosaccharide, potassium fulvate, amino acid and purified water and is obtained by mixing the secondary bacterial liquids obtained from secondary culture of bacterial strainsfor fermentation after primary culture and secondary culture. The microbial agent can be directly absorbed by the plant roots, improve soil characteristics, improve soil nutrients, decompose soil salt, promote growth and development of the plant roots and prevent the plant roots from being damaged by pathogenic bacteria; meanwhile, the microbial agent with multiple bacterial groups is obtained bycompounding three kinds of bacteria and conducting deep fermentation, has high compounding capability and can well adapt to the differences of actual production raw materials, prescribed quality standards can be satisfied without adding fertilizer raw materials, and the demands for large-scale commercialization can be met.

Description

Technical field [0001] The invention relates to the technical field of agricultural soil fertilizers, in particular to a microbial inoculum for solving the physiological obstacles of plant roots and a preparation method thereof. Background technique [0002] As a developing country, agriculture is still an important basic industry that supports my country's national economic construction and social development. It mainly includes five industrial forms: plantation, forestry, animal husbandry, fishery, and sideline industry. Among them, the planting industry accounts for the largest proportion, and its output value generally accounts for more than 50% of the agricultural output value. In addition, the stable development of the planting industry, especially the development of food crop production, has an impact on the development of animal husbandry, industry and people’s living standards. The improvement of China’s national economy is of great significance to the development of Chi...
