Traditional Chinese medicine living bacterium film-coated sustained and controlled release composite microorganism fertilizer and preparation method thereof

Abstract

The invention relates to the technical field of agricultural fertilizer and in particular relates to traditional Chinese medicine living bacterium film-coated sustained and controlled release composite microorganism fertilizer and a preparation method thereof. The traditional Chinese medicine living bacterium film-coated sustained and controlled release composite microorganism fertilizer is prepared by taking traditional Chinese medicines and microorganism flora as raw materials through a vegetable oil film coating technology. According to the fertilizer provided by the invention, the releaseof the fertilizer can be effectively controlled, and the fertilizer efficiency and the utilization rate of the fertilizer are improved; a product contains various traditional Chinese medicine components and contains rich active substances including alkaloid, terpenoids, phenols, flavonoids, medium and trace elements and the like; the product has insect-prevention and disease-resisting effects andcan be used for promoting healthy growth of crops and greatly improving the immunity and stress resistance of the crops; traditional Chinese medicine residues have relatively abundant nutritional functions and contain rich nutrients including macro-elements including nitrogen phosphorus potassium, medium and trace elements, microorganism flora, matched traditional Chinese medicine organic mattersand the like; the requirements of the crops on the nutrients are comprehensively met; and meanwhile, an active enzyme and a secondary metabolite, which are generated by the composite microorganism flora, have the properties of adjusting the potential of hydrogen of soil, improving the soil environment, degrading the pesticide residues, activating the activity of the soil and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a slow-controlled release compound microbial fertilizer coated with living Chinese medicine bacteria and a preparation method thereof. Background technique [0002] The application of chemical fertilizers has made an important contribution to the improvement of my country's grain production. However, in recent years, the problem of unscientific and irrational application of chemical fertilizers has become increasingly prominent. The average utilization rate of chemical fertilizers is only 20% to 35%, which leads to soil ecological balance, nutrient balance and Food security has problems, and at the same time, the loss of fertilizers has also caused environmental pollution. [0003] In February 2015, the Ministry of Agriculture issued the "Action Plan for Zero Growth in Fertilizer Use by 2020", proposing "strive to achieve zero growth in the use of chemical fertili...
