Preparation method of mosquito eradication preparation special for livestock and poultry breeding houses

Abstract

The invention discloses a preparation method of a mosquito eradication preparation specially used for livestock and poultry breeding houses, which belongs to the technical field of biological preparations compounded by microorganisms and enzymes and is characterized by comprising a fermentation process, a pretreatment process, an extraction process, a separation process and compounding of the mosquito eradication preparation. The preparation method of a mosquito eradication preparation specially used for livestock and poultry breeding houses has the beneficial effects that the environment-friendly mosquito killer is formed by compounding the mosquito killing streptomyces fermentation liquor and the enzyme, mosquito larvae can be effectively killed, the survival rate of mosquitoes is reduced, the enzyme can effectively decompose organic pollutants in the environment, the environment-friendly mosquito killer plays a role in deodorizing a breeding house while killing mosquitoes, and therefore breeding of the mosquitoes is further reduced; and streptomyces mosquito eradication thalli are separated from fermentation liquor, odor caused by spoilage of the streptomyces mosquito eradication thalli is avoided, the streptomyces mosquito eradication thalli are subjected to wall breaking treatment by utilizing chitinase, then separation is performed, the problem of loss of effective components caused by separation of the streptomyces mosquito eradication thalli from the fermentation liquor is avoided, and meanwhile, the problems of difficulty in filtration and activity reduction caused by wall breaking are solved.

Description

Technical field: [0001] The invention belongs to the technical field of biological preparations compounded by microorganisms and enzymes, and more specifically relates to a preparation method of a mosquito-killing preparation specially used in livestock and poultry breeding pens. Background technique: [0002] In livestock and poultry breeding pens, due to the existence of septic tanks, drainage ditches, water ponds, water tanks, etc., and some organic waste such as excrement and scattered feed of livestock and poultry cannot be cleaned up in time, it is very easy to breed mosquitoes. It affects environmental sanitation, and mosquito bites may also spread diseases and endanger the health of livestock, poultry and farmers. [0003] In order to get rid of mosquitoes well, there are currently many means, such as installing blue light mosquito lamps or spraying mosquito repellent drugs, but installing blue light mosquito lamps is more effective for moths, and less effective for ...

Problems solved by technology

[0002] In livestock and poultry breeding pens, due to the existence of septic tanks, drainage ditches, water ponds, water tanks, etc., and some organic waste such as excrement and scattered feed of livestock and poultry cannot be cleaned up in time, it is very easy to breed mosquitoes. Affects environmental sanitation, and mosquito bites may also spread diseases, endangering the health of livestock, poultry and farmers

[0003] In order to get rid of mosquitoes well, there are currently many means, such as installing blue light mosquito lamps or spraying mosquito repellent drugs, but installing blue light mosquito lamps is more effective for moths, and less effective for mosquitoes. In order to provide better effect, it is necessary to add blue light The number of mosquito lamps will inevitably affect the lives of livestock and poultry; and spraying mosquito repellent drugs has certain safety hazards
