Soil biological activator and preparation method thereof

Abstract

The invention relates to a soil biological activator and a preparation method thereof. The biological activator is prepared by taking agricultural byproducts as main raw materials, inoculating compound strains of saccharomyces cerevisiae, lactobacillus pentosus, bacillus natto and plant nitrogen-fixing bacteria and adopting liquid deep fermentation and bacterial dissolution technologies; and the obtained fermentation product contains few viable bacteria, so the storage time of the product is long and the use effect is stable. The soil biological activator contains rich polypeptide, polysaccharide, vitamin, organic acid, biological enzyme and mineral elements, provides high-activity carbon source and growth factors for soil microorganisms, can activate the soil microorganisms for a long time, increases the number and the varieties of soil microorganism aerobic bacteria and soil actinomycetes, improves the soil enzyme activity, and can promote the growth of the plant root system, improvethe photosynthetic efficiency of leaves and increase the yield of crops.

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
