Abstract
The invention relates to a method for preparing mosquito eradication granules by virtue of wheat straws, belongs to the field of mosquito prevention, and aims to overcome the shortcoming that diseases such as asthma are probably induced by substances harmful to human bodies in smoke produced by combustion of a conventional mosquito eradication substance. The method comprises the following steps of mixing and stirring carbonized wheat straw pellets and quisqualis indica in a sealing manner, adding absolute ethyl alcohol, permethrin, silica gel and lactic acid, adding carbon dioxide, and performing stirring, filtering and air-drying. The method is simple and convenient to operate, and the mosquito eradication granules have remarkable mosquito eradication effects, and are nontoxic and harmless to human bodies after being combusted.
Description
Technical field
The present invention relates to a kind of method utilizing wheat stalk to prepare killing mosquitoes particle, belong to insect protected field.
Background technology
The annual summer harvest in recent years and when the autumn and winter, always has the stalks such as a large amount of wheats, corn to burn in field, creates a large amount of heavy smog, not only become the bottleneck problem of rural environmental protection, even become the arch-criminal of bringing disaster to urban environment.Especially, after wheat harvest, a large amount of wheat straws is had to pile up between field or in courtyard.Such one is hold fire hazardous; Two is that wheat straw chance rain can go rotten, and contaminated environment, affects health.So wheat stalk industrialization used, can be used as the raw material etc. of insulation material, paper pulp raw material, all kinds of light weight board and packaging material.These comprehensive utilizations, have not only transformed a large amount of waste straw, have eliminated potential environmental pollution, and had good economic benefit, achieve the circulation of natural matter and energy.
General mosquito to start to occur annual April, reaches activity peak to mid or late August.Mosquito can propagate various diseases, and as Anopheles sinensis propagates malaria, Culex tritaeniorhynchus, Culex pipiens pallens propagate encephalitis, and Aedes aegypti, aedes albopictus propagate dengue fever, and Anopheles arthropophagus propagates filariosis etc., very harmful to the mankind.The entomologist Da Liai covering Billy's dust centre of research and development says, mosquito can tell some molecule that human cellular activity produces well, the lactic acid produced when the carbonic acid gas produced during as breathed and strenuous exercise, and the material of some people secretion is more than others.Therefore, those secretions and breathe vigorous people, just more easily become the target of mouth under mosquito.
Summary of the invention
The technical problem that the present invention mainly solves: contain many harmful materials in the cigarette of the substance combustion of current killing mosquitoes, likely bring out the drawback that the diseases such as asthma mostly are, provide a kind of method utilizing wheat stalk to prepare killing mosquitoes particle, wheat stalk particle after charing and fruit of Rangoon creeper's mixing are sealed stirring by the method, add absolute ethyl alcohol, permethrin, silica gel, after lactic acid, stir after adding carbon dioxide again, filter, air-dry, the method preparation method is simple, easy to operate, killing mosquitoes Be very effective, and it is harmless to human non-toxic after burning.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
(1) get wheat stalk to put into cracker and pulverize, be ground into 10 ~ 30 order particles, obtained particle is put into water, add the phosphoric acid solution that mass fraction is 80 ~ 85% more wherein, its addition is 15 ~ 18% of wheat stalk particle quality, soak 12 ~ 15min, then filter, filtered fluid is collected for subsequent use;
(2) above-mentioned filtrate is put into retort and carry out charing 2 ~ 3h, temperature is set to 450 ~ 500 DEG C, is then taken out by the wheat stalk particle after charing, is cooled to 28 ~ 35 DEG C, washing is carried out 2 ~ 4 times with the filtered fluid collected by above-mentioned steps, then by its natural air drying;
(3) the wheat stalk particle after air-dry is put into container, add the fruit of Rangoon creeper wherein, its addition is 40 ~ 50% of wheat stalk particle quality, seal slow heating to it to stir simultaneously, every 10min heats up 3 DEG C, when being warming up to 55 ~ 60 DEG C, stops heating up, insulation 40 ~ 50min, is then taken out and is cooled to room temperature;
(4) the wheat stalk particle obtained by step (3) is put into container, add absolute ethyl alcohol wherein to flood wheat stalk particle, add the permethrin of Wheat Straw granular mass 5 ~ 9%, add the silica gel of Wheat Straw granular mass 8 ~ 10% and add the lactic acid of Wheat Straw granular mass 7 ~ 10%, airtight container, carbonic acid gas is used to remove the gas of internal tank, keep temperature 55 ~ 60 DEG C, stir 30 ~ 35min, then filter, the wheat stalk particle natural air drying after filtration.
Application method of the present invention: the mosquito grabbing 100 work, puts in closed mosquito net, then mosquito particle the present invention prepared burns, and puts into mosquito net, quiet put one hour after, open mosquito net, find the mosquito that almost do not survive, except mosquito rate reaches 99%.
The invention has the beneficial effects as follows:
(1) the method manufacture craft is simple, and easy to operate, cost is low;
(2) the particle killing mosquitoes Be very effective that the method is obtained, and human body is safe from harm, natural safety.
