Biological organic fertilizer and production technology thereof

Abstract

The invention provides a biological organic fertilizer and a production technology of the biological organic fertilizer. The biological organic fertilizer comprises the following raw materials in parts by weight: 35-45 parts of vinasse, 25-35 parts of chicken manure, 5-16 parts of mushroom dreg, 7-15 parts of rice bran powder, 7-15 parts of straw and 0.01-0.03 part of a composite microorganism inoculant. The vinasse adopted by the biological organic fertilizer is small red sorghum 0 sauced vinasse, contains higher crude fat, crude fiber, crude protein and amino acid, is easy to corrupt, can accelerate rapid reproduction and digestion treatment of microorganisms, can shorten the production time of the organic fertilizer, and can increase microorganism culture content of the organic fertilizer; and the produced organic fertilizer can realize the characteristics of high crop yield, high nutrient substance content and high disease and insect resistance by selection of culture variety and quantity and improvement of the production technology.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a bio-organic fertilizer and a production process thereof. Background technique [0002] Organic fertilizer (manure) is a type of fertilizer made from natural organic matter decomposed or fermented by microorganisms. Also known as farmyard manure in China. Its characteristics are: wide source of raw materials, large quantity; complete nutrient content, low content; slow and long fertilizer effect, it must be decomposed and transformed by microorganisms before it can be absorbed by plants; good effect of improving soil and cultivating fertilizer. Commonly used natural fertilizers include green manure, human excrement, barn manure, compost, retting manure, biogas fertilizer and waste fertilizer. [0003] At present, most of the products on the market are for composting. Composting requires near-fermentation. Its basis is the microbial agent used for fermentation, and the comp...

Problems solved by technology

For example, the patent No. CN200910169274.2 is the patent "microbial agent and organic fertilizer produced by its fermentation", and the patent No. CN200510021056.6 is the patent "biological organic fertilizer and its preparation method". However, in production practice, Especially in large-scale production, the microbial compounding ability in these prior art microbial inoculants is insufficient

Due to the raw materials for organic fertilizer fermentation, such as animal manure and plant fibrous waste, due to different sources and different batches, there are certain differences in their carbon and nitrogen content, pH value, inorganic salts, trace elements, etc. The combination cannot well adapt to the differences in raw materials in actual production, and cannot exert stable fermentation ability for variable raw material batches. The use of such microbial agents with insufficient microbial compounding ability will cause the quality of fermented organic fertilizers to be unstable, completely deviated from The original intention of organic fertilizers has been lost, and it is difficult to meet the needs of large-scale commercial production
