Problems solved by technology

[0004] But, the method for above-mentioned chelation conditioning modified inorganic compound fertilizer generally has the following problems: 1) in the chelation reaction process, the reactor wall and the stirring paddle are easy to accumulate material, resulting in difficulty in blanking; 2) after The compound fertilizer after chelation modification is likely to cause serious material blockage in the material making machine, affecting normal production, and at the same time, it is easy to cause the material particles produced by the material making unit to loosen and stick together into blocks, which makes it difficult to spray liquid bacteria normally. ; 3) After the compound fertilizer after the chelation modification is mixed with the bacterial agent, the bacterial classification survival rate is still less than 3%

Abstract

This invention discloses a method to increase the culture survival rate in microorganism compound fertilizer which contains the following steps: (1) weighing a certain amount of inorganic fertilizer, glacial acetic acid, dimethylformamide and acetone and putting them in the reaction vessel. Stirring the mixture for a while under the temperature of 45oC- 50oC; (2) adding a certain mass ratio of polyethylene glycol 400, polycaprolactone and carboxymethylcellulose. Stirring them under a constant temperature and making them react for a while (3) adding a certain mass ratio of cyclohexane. Stopping temperature control and stirring. Cooling it down naturally to room temperature and discharging the material. The method to increase the culture survival rate in microorganism compound fertilizer provided by this invention has very simple technology operation and can effectively enhance the culture survival rate in microorganism compound fertilizer.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, and in particular relates to a method for improving the survival rate of strains in microbial compound fertilizers. Background technique [0002] Microbial compound fertilizer is a new type of biological compound fertilizer. The existing research results show that it has a very broad application prospect, which can improve the efficiency of chemical fertilizer use, reduce environmental pollution, increase yield and improve crop quality. It is compounded by compound fertilizer and bacteria. This compound fertilizer not only contains a large number of living microorganisms, but also contains one or more plant nutrients. It can not only stimulate crop growth through biological effects, improve fertilizer efficiency, but also provide exogenous nutrients to crops. [0003] Microbial compound fertilizer is composed of inorganic compounds such as urea, monoammonium phosphate, potassium chl...
