Preparation method of organic microbial fertilizer

Abstract

The invention discloses a preparation method of organic microbial fertilizer. 26-35 parts of livestock and poultry manure, 13-18 parts of sweet potato powder, 10-17 parts of clear flour, 25-40 parts of straw, 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 mussel powder, 20-30 parts of wood chips, 5-10 parts of molasses, 1-2 parts of multivitamins, 1-3 parts of compound amino acid, 5-8 parts of potassium polymetaphosphate, 1-2 parts of trace elements, 7-13 parts of potassium ore powder, 10-16 parts of phosphorus ore 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 are taken.. The preparation method of the organic microbial fertilizer is used to effectively overcome the defects that the organic microbial fertilizer is long in fermentation period, short in strain survival time, insufficient in activity and not easy to preserve. The organic microbial fertilizer has the advantages of improving the soil environment while providing the nutrition needed by the growth of crops, thus obtaining double benefits, and accordingly well promoting the sustainable and healthy development of the agricultural production in China.

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
