Problems solved by technology

However, in recent years, due to the intensification of soil acidification, the problems of soil compaction, salinization, and the reduction of soil nutrient utilization rate have emerged one after another. In addition, problems such as unreasonable fertilization and excessive soil utilization cannot be effectively suppressed, resulting in serious damage to the soil aggregate structure. Soil permeability and soil water suction become poor, soil water retention and storage capacity and soil cation exchange capacity decrease, which is not conducive to crop growth

Abstract

The invention discloses a microbial improver for improving a soil aggregate structure, and application thereof in soil improvement treatment. Functional microbial agents are Bacillus amyloliquefaciensand Bacillus velezensis, have the effect of promoting crop growth, and can prevent diseases and promote growth while improving soil. Activated humic acid, decomposed tobacco stem and tobacco powder,tobacco stem and tobacco powder activated carbon, clay minerals and the functional microbial agents are used as raw materials to prepare the soil improver for soil improvement and treatment, the pH value of the soil is always kept stable; the permeability of the soil can be improved, the water retention and storage capacity of the soil is enhanced, the cation exchange capacity of the soil is increased, finally, the purposes of improving the soil structure, improving the physicochemical properties, improving the soil fertility, keeping water and soil and improving the contaminated soil are achieved, and good environmental conditions are provided for growth and development of crops and microorganisms and high and stable yield of the crops.

Description

technical field [0001] The invention belongs to the technical field of microbial preparation, and in particular relates to a microbial modifier for improving soil aggregate structure and application thereof. Background technique [0002] The reason why the aggregate structure is dubbed the best soil structure is because the aggregate structure plays an important role in coordinating the balance of soil water, fertilizer, air, heat, bacteria and other aspects. However, in recent years, due to the intensification of soil acidification, the problems of soil compaction, salinization, and the reduction of soil nutrient utilization rate have emerged one after another. In addition, problems such as irrational fertilization and excessive soil utilization cannot be effectively suppressed, resulting in serious damage to the soil aggregate structure. Soil permeability and soil water suction become poor, soil water retention and storage capacity and soil cation exchange capacity decreas...
