Efficient biological bacterial fertilizer and preparation method

Abstract

The invention discloses efficient biological bacterial fertilizer and a preparation method. The efficient biological bacterial fertilizer comprises fermentation microbial strains, function microbial strains, enzymic preparations, shale, rice bran, chitosan, plant ash, bone meal, mushroom dregs, discarded tobacco leaves and livestock manure proportionally. The preparation method includes cultivating microbial strains into the fermentation microbial strains; mixing the fermentation microbial strains with the shale, the rice bran, the plant ash, the bone meal, the mushroom dregs, the discarded tobacco leaves and the livestock manure proportionally and adding water to the mixture to adjust the water content to 50%; adding the function microbial strains, the enzymic preparations and the chitosan after fermentation, and smashing, screening, inspecting, packaging and warehousing an obtained fermented material. The efficient biological bacterial fertilizer is rich in beneficial microorganisms and medium trace elements, soil organic matter content and soil micro-ecological environment are improved, continuous cropping diseases of plants are also improved, plant growth is promoted, crop yield is increased, pest and disease damage is reduced, crop quality is improved and cost is saved.

Description

technical field [0001] The invention relates to the technical field of biological agriculture, in particular to a high-efficiency biological bacterial fertilizer and a preparation method thereof, which are mainly used in organic agricultural production and soil physical and chemical improvement, increasing soil organic matter, and increasing soil microbial content. The most essential and remarkable feature of the high-efficiency biological bacterial fertilizer is that it is a living and living fertilizer, which is a biological bacterial fertilizer produced by industrialized cultivation and fermentation of one or several beneficial microorganisms. The fertilizer increases the yield of crops through the life activities of microorganisms contained in it, but it is not limited to increasing the supply level of plant nutrients, but also includes the secondary metabolites produced by them, such as the stimulating effect of hormones on plants . Promote the absorption and utilization...

Problems solved by technology

3. Nutrient imbalance, serious accumulation of nitrate, serious lack of trace elements

4. Soil acidification intensifies, PH changes too much, long-term application of chemical fertilizers accelerates soil acidification

Some organic fertilizers that have appeared in recent years are purely decomposed and fermented products, which cannot satisfy functional research such as disease resistance, replantation resistance, and heavy metal degradation effects, and have no substantial effects on nitrogen fixation, phosphorus dissolution, and potassium dissolution. breakthroughs, are stuck in a single function

[0003] At present, the existing technology simply ferments fermented strains and organic materials to produce organic fertilizers. It has no functions of nitrogen fixation, phosphorus dissolution, and potassium dissolution, and has no effect of insect and disease resistance. Its trace elements and growth factors are insufficient, reducing soil fertility. The characteristics of the insignificant effect of heavy metals
