Abstract
The invention discloses a selenium-enriched compound microbial organic fertilizer with a humic acid coating film and a preparation method thereof. The selenium-enriched compound microbial organic fertilizer is prepared by taking fowl manure and furfural residues as main raw materials which are used as carriers of a selenium element and various types of microbial strains, and taking active carbon fine powder, amino acid chelated selenium, a special bacterium agent for composting the organic fertilizer, a JT compound microbial bacterium agent and an EM compound microbial bacterium agent as auxiliary raw materials, and spraying a coating film on product particles by adopting a humic acid based film coating agent. The preparation method comprises the following steps: preparing the main raw materials, preparing the auxiliary raw materials, preparing various types of compound microbial bacterium agents, carrying out three times of biologic fermentation processes, and carrying out subsequent processing. The selenium-enriched organic fertilizer prepared by the invention can be widely used for producing selenium-enriched agricultural products, and the content of the selenium element in the agricultural products is effectively increased; recycling and harmless comprehensive utilization of excrement of large-scale bred livestock and poultry and biomass wastes of a furfural industry is realized, so that the environmental pollution is reduced, and the breeding cost and the production cost of the furfural industry are reduced; and the social and economic benefits of enterprises are improved, and the selenium-enriched compound microbial organic fertilizer has important demonstration and popularization values.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of bio-organic fertilizer production, and in particular relates to a selenium-enriched compound microbial organic fertilizer with a humic acid coating and a preparation method thereof. [0003] Background technique: [0004] Selenium is a very rare chemical trace element with properties between metals and non-metals. Modern medical research has proved that selenium is a very important trace element necessary for human life activities. Selenium is a multifunctional life nutrient. A certain amount of selenium is extremely important for improving human immune function, anti-aging, and inhibiting the occurrence of tumors. Selenium deficiency in the human body can induce cancer, cataract, cardiovascular and other diseases. However, excessive selenium content in the body can lead to selenium poisoning. The important physiological functions of selenium on the human body have attracted more and more attent...
