Granular biological organic fertilizer

Abstract

The invention relates to a microbial fertilizer, in particular to a granular biological organic fertilizer. The preparation method is as follows: selecting azotobacter chrococcum, phosphate-solubilizing bacteria including bacteria megaterium and pseudomonas sp and a potassium-releasing bacterium circulans; carrying out amplification culture; adopting grass carbon for adsorption; carrying out airing and placing the products into capsules to prepare a granular bacterial agent; then sterilizing chicken manures and humic acid and grinding urea and monoammonium phosphate into powder with a grinder; adding water to the chicken manures, urea, monoammonium phosphate, potassium chloride, humic acid and zinc sulfate and stirring the mixture uniformly to prepare the granular organic fertilizer and finally mixing the prepared bacterial agent capsules with the organic fertilizer in a weight ratio of 1:10. The number of the active viable count in the fertilizer is ensured and the microbial fertilizer has prominent effect of self-decomposing the nutrients in the soil and especially effectively utilizes the phosphorus and potassium resources in the soil. After the fertilizer is applied to the corns for growth, the yield of the crops can be steady or increased, the beneficial microorganisms in the soil are increased and simultaneously the contents of available nitrogen, available phosphorus, available potassium and soil organic matters in the soil can be improved to some extent.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a granular bio-organic fertilizer. Background technique [0002] "Shanxi Agricultural Sciences" No. 4, 2010, "A Preliminary Discussion on the Combination and Survival of Microbial Strains in Granular Biological Fertilizers" Liu Xiaofeng, Hong Jianping, Xie Yinghe (School of Resources and Environment, Shanxi Agricultural University, Taigu, Shanxi 030801) In this article, A biological compound fertilizer is introduced, which is a new type of fertilizer produced by inoculating effective microorganisms on the basis of organic and inorganic compound fertilizers. In the process, through the life activities of microorganisms, organic matter and minerals are decomposed to release nutrients, and bacterial fertilizers or microbial activators are used to improve the growth and nutritional conditions of soil and crops, which can quickly mature the soil, fix nitrogen in the air, participate in the tr...

Problems solved by technology

[0003] However, the specific types of nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solubilizing bacteria, and other technical solutions are not given, which affects the understanding and implementation of technical personnel

And its actual fertilization implementation effect is also not perfect enough, unsatisfactory.
