Three-acid mixed fermentation bio-organic fertilizer and preparation method of fertilizer as well as application of fertilizer in tobacco planting

Abstract

The invention discloses a three-acid mixed fermentation bio-organic fertilizer which uses rapeseed dregs, bean pulp, fulvic acid and fermentation microorganism bacterium agents as raw materials, the raw materials are fermented and then the fermented raw materials are mixed with a functional microorganism bacterium agent and microelement chelate powder to form a novel bio-organic fertilizer which is rich in fulvic acid, amino acid, linoleic acid and other organic acids and function microbial flora, is high in fertilizer efficiency and strong in activity, and is obviously superior to common organic fertilizers in the aspects of improving soil and improving the crop resistance, yield and quality. The functional microorganism bacterium agent is prepared in the preparation process of the bio-organic fertilizer, and the functional microorganism bacterium agent is high in survival rate in the fertilizer and high in effectiveness compared with those of common bactericide. After being applied to tobacco planting, the bio-organic fertilizer can be used for promoting formation of aroma substances in tobacco, improving the tobacco quality and increasing the yield of the tobacco.

Description

technical field [0001] The invention relates to the field of biological fertilizers, in particular to a biological organic fertilizer and its preparation method and application in tobacco planting. Background technique [0002] my country is the world's largest consumer of chemical fertilizers. Chemical fertilizers play an irreplaceable role in my country's agricultural production. However, long-term and excessive application of chemical fertilizers will inevitably bring about a series of hazards such as environmental pollution, soil degradation, and decline in the quality of agricultural products. A large number of studies have shown that bio-organic fertilizers can fertilize soil, improve soil structure, increase soil enzyme activity, etc., and can effectively compensate for the damage caused by excessive use of chemical fertilizers to soil. At present, due to the different raw materials and production and fermentation methods of bio-organic fertilizers on the market, thei...

AI Technical Summary

Problems solved by technology

[0009] At present, bio-organic fertilizers focus on the function of functional microorganisms, ignoring the effect of organic fertilizers on improving soil and providing nutrients to crops, resulting in low humus, nutrients and other effective components in organic fertilizers, and the fertilizer efficiency of bio-organic fertilizers is not fully utilized.

However, bio-organic fertilizers also have certain deficiencies in the production process, mainly because most of the bacterial agents used in the fermentation process are broad-spectrum bacterial agents, which are not targeted to different organic materials, making the fermentation efficiency low and the fermentation cycle short. Long, low-quality decomposed products

In addition, due to the inconsistency in the production process and strain sources of bio-organic fertilizers, after the functional strains are inoculated into the fertilizer, the number of effective bacteria is low, easy to inactivate, and poor in functionality.
