Method of producing organic fertilizer by utilizing fag-end of extracted camptothecine

Abstract

The present invention aims that by using the excellent bacteria strain screened from Camptotheca acuminata leaf or seed in different rot degree as strain for production, the residue after camptothecine extraction is air dried, alcohol evaporated, mixed with wheat bran, cane sugar, calcium sulfate, urea and water, and fermented at high temperature to form organic fertilizer capable of being utilized by plant. The present invention can eliminate the environmental pollution caused by the residue after camptothecine extraction.

Description

Technical field [0001] The invention belongs to a method for preparing organic fertilizers from waste residues in the field of biological fertilizers, and particularly relates to fermenting waste residues extracted from camptothecin into organic fertilizers by means of microorganisms. Background technique [0002] Since Indian scholar Edward Howard started modern composting in 1925, it has been widely used in the composting of garbage, human excrement, sewage sludge, leaves or straw and some other organic waste. However, most of these wastes are used to prepare fertilizers without adding any microbial preparations, and the highest temperature of the pile is only 45°C, and the primary fermentation starts to cool down prematurely, which is far from meeting the harmless requirements of high-temperature fertilizer production; From the point of view of its physical properties, the waste wood fiber in the pile without microbial preparations has not been completely decomposed, and ...

Problems solved by technology

However, most of these wastes are used to prepare fertilizers without adding any microbial preparations, and the highest temperature of the pile is only 45°C, and the primary fermentation starts to cool down prematurely, which is far from meeting the harmless requirements of high-temperature fertilizer production; From the point of view of its physical properties, the waste wood fiber in the pile without microbial preparations has not been completely decomposed, and flies and other insect eggs will be bred prematurely, and odor will be produced, which will pollute the environment.

And the cycle is long, the fermentation process is not easy to control

The existence of these shortcomings seriously restricts the fast and effective treatment of these wastes, and it is urgent to improve this

[0003] With the vigorous development of the pharmaceutical industry, especially in the production of herbal medicines, a large amount of waste residues will inevitably be produced, and there are certain toxicity in the waste residues, but the treatment of these waste residues is still blank. Putting it in the environment will inevitably cause serious pollution to the environment. The waste residue produced after camptothecin extraction is one of them. There is still a certain amount of camptothecin in this waste residue. Camptothecin is harmful to people, animals and plants Toxic effects, if left untreated, will not only cause resource waste but also cause environmental pollution, it is imperative to properly deal with it

However, there is no precedent for its effective treatment
