Problems solved by technology

In China, more than 200,000 tons of cassava distiller's grains are produced every year. However, at present, the utilization rate of cassava distiller's grains is extremely low, and only some fresh cassava distiller's grains are used to make feed, which not only causes waste of resources, but also pollutes the environment
[0004] The main components of cassava distiller's grains are: 78% of cellulose, 3% of polysaccharides, 9% of protein, and 10% of others; there are a lot of short fibers in cassava distiller's grains, which will become moldy after being piled up in the natural environment for 5 days, and After natural fermentation, when it is used as a fertilizer, experimental studies have found that its fertilizer efficiency is very low, and it is difficult to dehydrate and store after fermentation, which seriously restricts the reuse of cassava distiller's grains

Abstract

The invention relates to cassava distiller's grain organic fertilizer and a production method thereof, belonging to the technical field of fertilizer. The method comprises the steps of firstly, adding cellulase and effective microorganisms (EM) bacteria liquid into cassava distiller's grain, stirring until an obtained mixture is evenly mixed, carrying out anaerobic fermentation, and centrifuging a fermentation product; freeze-drying the obtained supernatant to obtain a material A; adjusting the pH value of the obtained precipitate residue to 6-7, then evenly mixing the precipitate residue with sugar mill filter mud, fulvic acid, zeolite powder and tobacco waste, and carrying out natural retting fermentation to obtain a material B; finally, evenly mixing the material A, the material B, magnesium sulfate, ammonium molybdate, epsilon-polylysine and potassium dihydrogen phosphate according to a certain proportion to obtain the cassava distiller's grain organic fertilizer. The cassava distiller's grain organic fertilizer is prepared by taking the cassava distiller's grain as a raw material, thus being low in production cost, reducing the environmental pollution and changing waste into valuable; the prepared organic fertilizer is obvious in yield increasing effect and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a cassava distiller's grain organic fertilizer and a production method thereof. Background technique [0002] Distiller's grains, also known as red grains, distiller's grains, dregs, etc., are the residues left after brewing rice, wheat, sorghum, etc. Distiller's grains are the direct leftovers in the brewing process. It not only contains a certain proportion of grain, which can save the concentrate for feeding cattle, but also contains rich crude protein, which is about 2-3 times higher than that of corn. It also contains various trace amounts Elements, vitamins, yeast, etc., and the content of lysine, methionine and tryptophan is also very high. [0003] Many alcohol production enterprises use cassava for alcohol production, and finally produce a large amount of cassava distiller's grains. More than 200,000 tons of cassava distiller's grains are produced in Ch...
