Preparation method of organic microbial fertilizer

Abstract

The invention discloses a preparation method of an organic microbial fertilizer. The organic microbial fertilizer comprises by weight, 26-35 parts of livestock and poultry night soil, 13-18 parts of sweet potato flour, 10-17 parts of wheat middling, 25-40 parts of straws, 30-40 parts of peat soil, 25-35 parts of weathered coal, 10-15 parts of mushrooms, 10-15 parts of algae, 12-16 parts of freshwater mussel powder, 20-30 parts of wood chips, 5-10 parts of honey, 1-2 parts of composite vitamins, 1-3 parts of composite amino acids, 5-8 parts of potassium polymetaphosphate, 1-2 parts of trace elements, 7-13 parts of potassium mineral powder, 10-16 parts of phosphate rock powder, 1-2 parts of humic acid, 5-8 parts of ammonium sulfate, 12-15 parts of borax, 3-7 parts of zinc sulfate, 5-8 parts of sodium carbonate and 7-10 parts of fatty acid acetic anhydride. The preparation method well solves the disadvantages of long fermentation period, and short viability time, activity insufficiency and difficult preservation of bacterial strains, The organic microbial fertilizer meets nutrition required by growth of crops, improves soil environment, has two purposes, and well promotes the sustainable healthy development of Chinese agriculture production.

Description

technical field [0001] The invention relates to the field of crop fertilizers, in particular to a method for preparing organic microbial fertilizers. Background technique [0002] With the continuous development of China's economy and the improvement of people's material living standards, people have put forward higher requirements for the safety and quality of agricultural products. "Green" and "organic" products are increasingly becoming people's choices for healthy living. For a long time, in order to achieve a simple and direct increase in crop production and income, we have been adopting an extensive development method, that is, the simple use of chemical fertilizers is the main method, and we only pay attention to the production and not to the protection and improvement of the soil environment. Although chemical fertilizers have brought us a lot of economic benefits to a certain extent, their limitations and destructiveness are becoming more and more prominent. For ex...

Problems solved by technology

Although chemical fertilizers have brought us a lot of economic benefits to a certain extent, their limitations and destructiveness are becoming more and more prominent. For example, long-term use of chemical fertilizers will destroy the acid-base balance of the soil, causing soil compaction, eutrophication, and Water retention, fertilizer retention and air permeability become poor. At the same time, the long-term excessive use of chemical fertilizers has also caused serious damage to the structure and growth environment of microorganisms in the soil.

Nowadays, the effect of chemical fertilizers on crop growth is becoming weaker and weaker due to factors such as the damage of chemical fertilizers to the soil and the dependence of crops on chemical fertilizers
