Production method for preparing organic fertilizer by performing aerobic composting fermentation on traditional Chinese medicine dregs

Abstract

A production method for preparing organic fertilizer by performing aerobic composting fermentation on traditional Chinese medicine dregs is characterized by comprising the following steps: firstly, pulverizing, grinding and sieving straw stalks and traditional Chinese medicine dreg powder, performing high-temperature sterilization treatment with a dilute acid solution, and drying; secondly, adjusting water content and pH value; thirdly, inoculating composite microbial inoculants and performing aerobic composting fermentation; finally, pulverizing and pelletizing the fermented traditional Chinese medicine dregs and the rice straws to prepare a fertilizer inner core, and forming a coating layer on the surface of the fertilizer inner core by taking gamma-glutamic acid and gelati as a coatingsustained-release agent to obtain the organic fertilizer prepared by performing aerobic composting fermentation on the traditional Chinese medicine dregs. The organic fertilizer provided by the invention realizes resource reasonable utilization of the traditional Chinese medicine dregs and the rice straw, is simple in fermentation process, low in cost input and easy to absorb by crops, and can promote the growth and development of the crops, increase yield, increase income and improve quality.

Description

Technical field [0001] The invention belongs to the field of fertilizers, and specifically relates to a production method for preparing organic fertilizers by aerobic composting of traditional Chinese medicine residues. Background technique [0002] Chinese traditional Chinese medicine enterprises produce up to 665,000 tons of plant-based Chinese medicine residues each year, of which about 10-15,000 tons are produced in our province. Traditional Chinese medicine residues generally have a high water content and belong to the category of wet materials. They are rich in a large amount of easily degradable sugars and small molecular organic compounds. They are easily decomposed by microorganisms if they are stacked in a natural environment for a long time. If they are not properly disposed of in time, It will pollute the natural environment and form irreversible losses. This situation is particularly serious in summer. Due to the high temperature in summer, it is easy to breed anaero...

Problems solved by technology

Traditional Chinese medicine dregs generally have a high water content and belong to the category of wet materials. They are rich in a large amount of easily degradable sugars and small molecular organic compounds. They are easily decomposed by microorganisms when they are piled up in the natural environment for a long time. If they are not properly disposed of in time, It will cause pollution to the natural environment and cause irreparable losses. This situation is particularly serious in summer. Due to the high temperature in summer, it is easy to breed anaerobic microorganisms, so that the surrounding areas of the stacking point are smelly, mosquitoes and flies are everywhere, Sewage crossflow poses a serious threat to human health
