Bacillus mucilaginosus bacterial fertilizer for farm onsite fermentation and applications thereof

Abstract

The invention relates to a bacillus mucilaginosus bacterial fertilizer for farm onsite fermentation, a preparation method thereof and applications thereof. The bacterial fertilizer comprises the following raw materials: bacillus mucilaginosus powder, colistin sulfate, natamycin, methionine, leucine, corn flour, soybean cake powder, fructose, disodium hydrogen phosphate, potassium chloride, and brown sugar. The colistin sulfate and natamycin in the bacterial fertilizer can inhibit the growth of fungi (such as pathogenic fungi, yeast, etc.) and gram negative bacteria (such as colibacillus, salmonella, etc.) during the fermentation process. The spore germinator (leucine, fructose, and methionine) can rapidly promote the germination of spores of bacillus mucilaginosus and improve the germination rate of spores. The provided bacterial fertilizer can be applied to the onsite fermentation and propagation in a simple and crude farm. The required equipment is simple. The using amount of bacterium is little. The cost is low. The fermentation broth obtained through onsite fermentation has the advantages of high content, good activity and few contaminating bacteria. The bacterial fertilizer can decompose potassium, prevent disease, promote growth, increase output, and improve product quality. The effect is stable.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a jelly-like bacillus bacterial fertilizer applied to on-site fermentation in farms and a preparation method and application method thereof. Background technique [0002] The average content of potassium in the earth's crust is 2.6%, and its abundance ranks fourth among all elements contained in the earth's crust. The soil potassium content is generally between 0.04-3.0%. According to the existing form, it is divided into water-soluble potassium, exchangeable potassium, non-exchangeable potassium and mineral potassium. The content and exchange of each form of potassium determine the potassium supply capacity of the soil. 90% of the potassium in the soil exists in the crystal structure of potassium-containing minerals such as mica and feldspar, and can only be absorbed and utilized by crops after being released from the crystal structure after a long weathering process.

AI Technical Summary

Problems solved by technology

[0008] The second is that the early stage of spore germination takes a long time, usually 4 hours before the spores will start to germinate. At this time, due to the large-scale reproduction of yeast and lactic acid bacteria in the "activation" solution, the pH drops rapidly, which can already inhibit the germination and reproduction of spores. , thus greatly affecting the germination of spores

[0009] The third is that the high-nutrient medium is also susceptible to infection of Escherichia coli, the original plant pathogenic bacteria and other harmful bacteria, resulting in poor effects after application and still have side effects

[0010] However, there has not been disclosed so far a jelly-like bacillus fertilizer that can better control miscellaneous bacteria and promote rapid germination of spores and is applied to on-site fermentation and propagation of farms.
