A kind of soil biological activator and preparation method thereof

Abstract

A soil biological activator and a preparation method thereof, wherein the biological activator uses agricultural by-products as the main raw material, is inoculated with composite strains of Saccharomyces cerevisiae, Lactobacillus pentosus, Bacillus natto and plant nitrogen-fixing bacteria, and adopts liquid submerged fermentation It is made by cell dissolution technology; the obtained fermentation product contains less live bacteria, so the product has a long storage time and stable use effect. The soil biological activator of the present invention is rich in polypeptides, polysaccharides, vitamins, organic acids, biological enzymes and mineral elements, and provides highly active carbon sources and growth factors for soil microorganisms, which can activate soil microorganisms for a long time and increase the aerobic activity of soil microorganisms. The quantity and type of bacteria and soil actinomycetes can increase the activity of soil enzymes; it can promote the growth of plant roots, improve the photosynthetic efficiency of leaves, and increase crop yield.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a soil biological activator and a preparation method thereof. Background technique [0002] Soil is the foundation of agricultural production, and healthy soil is a necessary condition for growing high-quality agricultural products and obtaining high yields. However, since the 1990s, excessive input of chemical fertilizers, a serious imbalance in the structure of fertilizer use, and an excessively high multiple cropping index have led to problems such as decline in soil fertility, soil compaction, soil acidification, severe soil-borne diseases, and degradation of soil biological properties in China. The soil problem needs to be solved urgently! [0003] The traditional method of supplementing organic fertilizers is limited by local resources, and the labor intensity is high, the amount of application is large, and the effect is slow; problems such as root burn and root-knot ne...

AI Technical Summary

Problems solved by technology

There are many types of high-content functional bacterial fertilizers on the market, but they have the following disadvantages: ①The use conditions of this type of product are harsh, and the effect is often poor due to the low survival rate of foreign functional bacteria after use; ②The number of effective viable bacteria decreases with storage time, Affect the efficacy; ③The registration threshold of functional bacterial fertilizer is low, the quality is uneven, and improper use can easily destroy the ecological balance of the soil
