Organic enzyme fertilizer and preparation method thereof

Abstract

The invention discloses an organic enzyme fertilizer and a preparation method thereof. The organic enzyme fertilizer is characterized by comprising the following raw materials by weight percentage: 2%-5% of liquorice roots, 2%-5% of dried kudzuvine root branches and leaves, 2%-5% of dried wild chrysanthemum, 1%-2.5% of oligosaccharides, 1.5%-3.5% of dried yeast, 4-10% of moringa oleifera extractsand the balance of water. According to the invention, substances which are difficult to absorb and anti-nutritional factors in moringa oleifera leaves can be transferred into nutrient substances suchas free amino acids and small molecule polypeptides which are easily absorbed by animals. By adopting a moringa oleifera leaf fermented product as a fertilizer additive, the quality of agricultural products is improved, soil-borne diseases are inhibited, crop stress resistance is enhanced, early maturity of crop is promoted, and soil organic matter and nitrogen, phosphorus, potassium and other nutrients are directly increased; and compared with the prior art, the organic enzyme fertilizer has the characteristics of zero pollution, high utilization rate, pure nature, increased yield, enhanced crop resistance and the like.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and more specifically relates to organic enzyme fertilizers and a preparation method thereof. Background technique [0002] my country is a large agricultural country with a large population and insufficient arable land resources. It feeds 21% of the world's population with 9% of the world's arable land. my country is also the country with the largest amount of fertilizer production and use in the world, among which the production and use of nitrogen fertilizer ranks first in the world, accounting for 9% of the world's arable land but consumes 30% of the world's fertilizer; the reason is that my country's fertilizer utilization rate Relatively low; the existing fertilizers for plants are mainly: [0003] Nitrogen fertilizer: that is, chemical fertilizers with nitrogen nutrients as the main component, including ammonium bicarbonate, urea, ammonium ammonium, ammonia water, ammonium chloride, ...

Problems solved by technology

[0009] (2) Organic pollutants mainly include phthalates, nitroaromatics, polycyclic aromatic hydrocarbons and halogenated hydrocarbons, etc., and their sources are mainly sludge, crop straw, etc., and crop straw is easily affected by pesticides, weeding, etc. Pollution from pesticides and tail gas emitted by automobiles and tractors, which also indirectly affects the safety of fertilizers;

[0011] (4) Pathogenic bacteria and insect eggs are derived from the addition of untested microbial strains, which can cause human or animal infections. In the past ten years, due to the continuous expansion of new varieties of biological fertilizers, the number of production strains has increased to more than 100 at present. Unsafe factors in the use of strains a
