Production method of ecological organic fertilizer based on earthworm dung

The invention relates to a method for producing organic fertilizer, in particular to a method for producing an ecological organic fertilizer based on manure, belonging to the technical field of modern agricultural biological organic fertilizer.

Background technique

Ecological organic fertilizer refers to the use of regional organic wastes to be produced by microbial decomposition and transformation, which not only has the ability to fertilize soil, increase crop nutrient supply, increase crop yield, improve the quality of agricultural products, but also reduce soil residual fertilizers, pesticide pollution, and cleanliness. Soil, a compound organic fertilizer or a microbial organic fertilizer that improves the ecological environment. It combines the advantages of microbial fertilizer, organic fertilizer and inorganic fertilizer, and is one of the important directions for the future development of fertilizer products.

A variety of beneficial microorganisms are separately cultured under suitable culture conditions and under suitable conditions, and then mixed with a culture material (adding a part of the adsorption or dispersion carrier if necessary) in a certain ratio, which is a common method for producing ecological organic fertilizer, but the production is The method is relatively complicated and requires specific culture equipment. The microbial diversity of the fertilizer after mechanical mixing is not natural and stable. Although many people have long discovered and clarified that many microorganisms have the effect of inhibiting or antagonizing the soil-borne diseases of crops, the microorganisms entering the commodity market have few organic fertilizers, because the proliferation of antagonistic bacteria in the field requires a certain premise. Factors such as soil properties, climatic conditions, crop types, and non-target pathogens other than target pathogens can affect the effects of microbial fertilizers.

1. Current status of production of common ecological organic fertilizer in China

At present, although there are many manufacturers of ecological organic fertilizer in China, the quality of ecological organic fertilizer products is not uniform and standardized, the effect is unstable, and the safety is low. There is still no national or local ecological organic fertilizer standard, especially the quantity and structure of beneficial microorganisms in ecological organic fertilizer, and the effect of fertilizer on soil and crops. A considerable amount of ecological organic fertilizer does not have the ecological effect of regulating and improving soil micro-ecological systems or significantly increasing the comprehensive resistance of crops. 2. Development status of ecological organic fertilizer based on manure

蚯蚓 In the course of its life activities, it devours a large amount of organic matter, promotes the decomposition, transformation and (:, N cycle) of organic matter through the mechanical grinding of sand shovel and the synergy of microorganisms. The sputum is rich in bacteria, actinomycetes and Microorganisms such as fungi. Through the life activities of beneficial microorganisms in earthworms, it is possible to analyze the phosphorus, potassium and trace elements in the soil that are not available in the soil, and to use available phosphorus, potassium and trace elements; Secretion of auxin, cytokinin, gibberellin, citric acid and other plant hormones, promote crop growth, regulate crop metabolism; propagate through the rhizosphere through beneficial microorganisms, produce mucopolysaccharides, mucus secreted by plants and mineral colloids, organic colloids Combined, the formation of soil aggregate structure, improve soil fertility and water storage capacity; a large number of microorganisms in earthworms increase the number and activity of microorganisms in the soil, and enhance the microbes in the diseased soil for nutrition and energy competition with pathogenic bacteria. Strive to limit the full play of the reproductive potential of pathogens (Hu Yanxia et al 2004; Arancon et al, 2006 It has been proved that sputum manure as a seedling base fertilizer and crop topdressing can increase the seed germination rate of various crops (including grains, legumes, flowers, vegetables and other field crops) to promote their growth. , increase production and improve quality (Arancon et al, 2004).

However, a viable large-scale production method which can effectively utilize the manure to carry out organic fertilizer production has not been disclosed in the prior art.
