Description
Technical Field
The invention relates to the technical field of fertilizer production, in particular to a method for producing an organic fertilizer by fermenting shrimp shells with microorganisms.
Background
EM (Effective Microorganisms) is composed of about 80 kinds of Microorganisms, and the EM was successfully studied by professor bijia phf of Youki university, Japan, in 1982 and put on the market in 80 years. The EM is a microbial preparation which is compounded by 10 microorganisms which are more than 80 and mainly comprise photosynthetic bacteria, lactic acid bacteria, saccharomycetes and actinomycetes. The action mechanism is to form competition of the EM bacteria and the pathogenic microorganisms for nutrition, and the EM bacteria are easy to survive and reproduce in the soil, so the EM bacteria can quickly and stably occupy the ecological status in the soil, and form a dominant community of beneficial microorganisms, thereby controlling the reproduction of the pathogenic microorganisms and the attack on crops. Is the development direction of ecological agriculture, and is more beneficial to the sustainable development of agriculture.
chitin, also called chitin and chitin, is insoluble in alkali and other organic solvents, and is also insoluble in water. In nature, it is widely found in shells of crustaceans such as lower plants, fungi, shrimps, crabs and insects, cell walls of eubacteria, and the like. The meclozine is widely applied to agricultural production, and can improve the yield and quality of crops and improve the capability of the crops in resisting diseases and pests and resisting adverse environments.
Carbonaceous material, mainly of plant and/or animal origin, which is applied to the soil to provide plant nutrition as its main function. Is prepared from biological substances, animal and plant wastes and plant residues, eliminates toxic and harmful substances in the biological substances, and is rich in a large amount of beneficial substances, including: various organic acids, peptides and rich nutrient elements including nitrogen, phosphorus and potassium. The fertilizer not only can provide comprehensive nutrition for crops, but also has long fertilizer efficiency, can increase and update soil organic matters, promote microbial propagation, improve the physical and chemical properties and biological activity of soil, and is a main nutrient for green food production.
