Multiple-effect liquid fertilizer and preparation method and application thereof

Abstract

The invention discloses multiple-effect liquid fertilizer and a preparation method and application thereof. The multiple-effect liquid fertilizer is prepared from, by mass, 50%-60% of small molecule organic carbon liquid, 10%-25% of nitrogenous substances, 5%-9% of phosphorus containing substances, 12%-20% of potassic substances, 5% of water-soluble silicon and 1%-8% of passivator, and the sum of the content of all the components of the liquid fertilizer is 100 percent. The liquid fertilizer can be used for preventing and curing soil-borne diseases and promoting growth of crop root systems. Waste liquid containing rich organic matter is adopted, organic carbon small molecule liquid is obtained through degradation, passivator which can passivate toxins, accumulated in soil, of the soil-borne diseases and basic N and P and K nutrition needed by crops are added, passivating of the toxins secreted by the soil-borne diseases is achieved, and growth of infection bodies of the soil-borne diseases is inhibited; meanwhile, growth of plant root systems is promoted, and stress resistance of the crops is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a preparation method and application of a multi-effect liquid fertilizer which can passivate plant pathogen toxins, inhibit pathogen infection, improve crop stress resistance, and promote plant root growth. Background technique [0002] In agricultural planting and production, with the unreasonable use of chemical fertilizers and continuous cropping of land, the soil micro-ecological environment deteriorates, and pathogenic bacteria and their secreted toxins accumulate in the soil, resulting in increasingly serious soil-borne diseases. [0003] For a long time, people have used a large number of chemical pesticides to prevent and control plant soil-borne diseases. On the one hand, they have destroyed the number of beneficial microorganisms, and on the other hand, they have increased the resistance of plant pathogens. In addition, pathogenic toxins are also one of ...

AI Technical Summary

Problems solved by technology

[0004] At present, the prevention and control of soil-borne diseases can only achieve good results by inhibiting the growth of pathogenic bacteria, or inactivating plant pathogenic toxins, or improving crop disease resistance.

[0005] 201010264889.6 A method of preventing and controlling plant soil-borne diseases is to use a kind of beneficial microorganisms in the prepared organic fertilizer to secrete special organic substances in the plant roots to inhibit the contact between soil-borne diseases and the roots to achieve the control effect, but the present invention does not consider the existing Plant pathogenic toxins, organic fertilizers can not meet the N\P\K and other nutrients needed for plant growth

However, it cannot provide nutrients during the growth period of crops, and after the organic fertilizer is applied to the soil, it will take a certain time for microbial degradation, which cannot guarantee the effective prevention and control of soil-borne diseases
