Problems solved by technology

However, the carrier used in the bio-organic-inorganic liquid fertilizer disclosed in this document has a weak ability to release beneficial bacteria after absorbing the bacterial liquid, which makes it difficult for the liquid fertilizer to provide enough beneficial bacteria to maintain the normal growth of crops.
[0007] To sum up, the existing technology has not yet solved the problem of how beneficial microorganisms can survive in the high-salt environment of compound fertilizers, the survival and reproduction of microorganisms after they are applied to the soil, and the coordination and synergy between microorganisms and compound fertilizers

Abstract

The invention provides a microbial compound fertilizer containing double-layer envelopes. The microbial compound fertilizer comprises a core layer, a first envelope layer and a second envelope layer; the core layer comprises compound fertilizer, the first envelope layer is organic carbon coated on the surface of the compound fertilizer, and the second envelope layer is microorganism coated on the surface of the organic carbon, wherein the mass ratio of the core layer to the first envelope layer to the second envelope layer is 10-5000:1-5:0.01-110. The microbial compound fertilizer containing double-layer envelopes enables microorganism to survive in high salinity environment in the early growth stage, increases the survival rate of microorganism entering the soil, prolongs reproduction time and achieves coordinative synergism of microorganism and the compound fertilizer.

Description

technical field [0001] The invention belongs to the field of biological fertilizers, and in particular relates to a microbial compound fertilizer containing a double-layer coating. Background technique [0002] Bio-organic fertilizer is a kind of fertilizer produced by inoculating some beneficial microorganisms on the basis of traditional organic fertilizers. The large amount of organic matter and beneficial microorganisms contained in bio-organic fertilizers can improve soil structure, restore soil microbial flora, inhibit the spread of harmful microorganisms, and maintain soil ecological balance. In addition to containing the macroelements and trace elements necessary for the growth and development of crops, bio-organic fertilizers also contain microbial metabolites and a large number of active beneficial microorganisms, which can not only promote crop growth, but also enhance crop disease resistance, increase crop yield, and improve the quality of agricultural products. ...
