Bacillus megaterium bacterial fertilizer for onsite fermentation in farm and applications thereof

Abstract

The invention relates to a bacillus megaterium bacterial fertilizer for onsite fermentation in a farm and applications thereof. The bacterial fertilizer comprises the following raw materials: bacillus megaterium powder, colistin sulfate, natamycin, inosine, lysine, corn flour, soybean cake powder, disodium hydrogen phosphate, potassium chloride, and brown sugar. The bacillus megaterium bacterial fertilizer can be applied to onsite fermentation and propagation in a farm. 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 (inosine and lysine) can rapidly promote the germination of spores of bacillus megaterium and improve the germination rate of spores. The provided preparation 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 microorganisms. The bacterial fertilizer can decompose phosphorus, 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 Bacillus megaterium bacterial fertilizer applied to on-site fermentation in farms and its application. Background technique [0002] The average content of phosphorus in the earth's crust is about 0.122%. During the process of soil formation, phosphorus migrates to a certain extent. With the progress of soil formation, the content of phosphorus in the soil also decreases. The phosphorus content of most soils in my country is between 0.043% and 0.046%, so the phosphorus content in the soil is relatively deficient. Since phosphorus is one of the 16 nutrient elements necessary for plant growth and development, crops mainly absorb phosphorus in chemical forms such as phosphate, while phosphorus in soil mainly exists in the state of fixed minerals, accounting for about 70% of the total phosphorus content. %, so the content of water-soluble inorganic phosphate ions in the soil p...

Problems solved by technology

[0006] 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. , thereby greatly affecting the germination of spores;

[0007] 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

[0008] However, there has not been disclosed so far about a Bacillus megaterium bacterial fertilizer that can better control miscellaneous bacteria and promote rapid germination of spores, which is applied to on-site fermentation and propagation of farms.
