A kind of biopesticide of killing aphids and compound method thereof
Technical field
The invention belongs to biological technical field, be specifically related to a kind of biopesticide and compound method of killing aphids.
Background technology
Aphid Species is various, and the world known about more than 4700 plants, and China just about has 1100 kinds.Its fertility is extremely strong, can breed 20-30 generation every year, and often huge for reproductive number.China, as large agricultural country, is extensively subject to the infringement of aphid simultaneously.But along with the development of agricultural industry, the hope green consumption that people are urgent again, the requirement particularly for the primary industry such as fruit, vegetables is strict especially.Many just because of Aphid Species, so the vegetation type of harm is also many.Current country carries out Green China, certainly also comprise urban afforestation, but aphid endangers for the view plant of urban afforestation equally huge.At present, the agricultural chemicals that people use is commonly chemical pesticide.Although the insecticidal effect of most phosphoramidite chemical agricultural chemicals is high, but easily cause more serious consequence in the normal region of chemical pesticide that uses, such as chemical pesticide residual harm people and animals, the poisoning that strong cytotoxic chemical agricultural chemicals causes, the pest resistance to insecticide often using chemical pesticide to cause strengthens.The variety of problems brought based on agriculturally using chemical pesticide, people start urgent to wish the not only material benefit of a kind of economy, effective nonhazardous but also the agricultural chemicals of environmental protection, improve agricultural product security sexual valence value.
Summary of the invention
The object of the present invention is to provide that a kind of insecticidal effect is high, with low cost, biopesticide killing aphids technology to environment and person poultry harmless.Use the method can greatly improve extensively by the agricultural product income effect of aphid insect damage, and ensure to reduce agriculturally to the pollution of environment.
The technical thought that the present invention takes is: by utilizing the symbiotic relation between aphid and ant, adds nontoxic camphor tree stem-leaf extract (camphor) and drive away ant in agricultural chemicals, makes it to remove symbiotic relation thus protection natural enemy of aphid; Reducing aphid immunocompetence by adding ash leachate destruction aphid surface protection tissue (triglyceride) in agricultural chemicals, providing nutrient to plant growth, Promoting plant growth simultaneously; By utilizing white muscardine fungi, parasitic relation between green muscardine fungus and aphid, in agricultural chemicals, add selectivity strong and to the broken ring aphid body tissue of the entomophagous parasite bacterium (white muscardine fungi, green muscardine fungus) of person poultry harmless, and make aphid dead; By utilizing saccharomycetic respiration principle, in agricultural chemicals, adding saccharomycete and a small amount of glucose, making saccharomycete decompose the honeydew of dead aphid body tissue and aphid secretion.The parts by weight wherein preparing each raw material needed for killing aphids biopesticide are: camphor 3-4 part, ash leachate 10-15 part, white muscardine fungi powder 0.2-0.3 part, green muscardine fungus powder 0.3-0.4 part, yeast powder 0.05-0.08 part, glucose pulvis 5-8 part.
A biopesticide compound method for killing aphids, comprises the following steps:
(1) the camphor tree branches and leaves in period short of rain in autumn are got, put into mortar after shredding to grind, steam distilled method is used after abundant grinding, the steam of camphor and camphor oil that has obtained is entered the dish type cooler of many rings again through wireway, the mixture of camphor and camphor oil and water can be obtained, by leaving standstill rear layering, remove camphor and the camphor oil mixture of gained after moisture, entered multiple method of steaming again and collected distillate under the condition of 155-200 DEG C, the crystalline solid of separating out after the distillate now collected cooling was crystallized camphor;
(2) get ash fully to mix with water, mixed weight ratio is 1: 1, and ash, after entering circadian immersion, filters gained supernatant and is leachate;
(3) white muscardine fungi powder, green muscardine fungus powder and yeast powder is taken by the weight of each component, mix adding pulvis without the white muscardine fungi powder activated, green muscardine fungus powder and yeast powder with biopesticide, obtain Mixed Microbes pulvis I, guarantee under the dry condition, avoid bacterial classification at medication front activating;
(4) take a small amount of glucose as above-mentioned actication of culture basic material by the weight of each component, glucose is made pulvis;
(5) crystallized camphor of gained, ash leachate, Mixed Microbes pulvis I, glucose pulvis are stirred by after the mixing of each component weight.Parts by weight are: camphor 3-4 part, ash leachate 10-15 part, white muscardine fungi powder 0.2-0.3 part, green muscardine fungus powder 0.3-0.4 part, yeast powder 0.05-0.08 part, glucose pulvis 5-8 part.
White muscardine fungi (Beauveria bassiana) in the present invention is stored in China typical culture collection center, and preservation bacterium number is CGMCC 3.03574.Green muscardine fungus (Metarhizium anisopliae) is stored in China General Microbiological Bacterial Strains Managing center, and preservation bacterium number is CGMCC 3.03676.Saccharomycete (Trichosporon capitatum) is stored in China typical culture collection center, and preservation bacterium number is CCTCC AY93140.Above bacterial classification is all bought in Hunan Yuyuan Biology Technology Co., Ltd.
Advantage of the present invention is:
1, avirulence: the camphor that the present invention adds, ash leachate, glucose pulvis all to people and animals' nonhazardous effect, not only substantially increase the insecticidal effect of medicine, but also provide nutrient, Promoting plant growth for plant.
2, nonstaining property: the camphor that the present invention adds is also volatile while playing desinsection anthelmintic action in the environment, can not cause harmful effect to environment; Ash leachate is alkalescent mixture, and its main component is potash, agriculturally not only can be used as concentrated fertilizer but also also having the effect of preventing damage by disease and insect, also can not produce harmful effect to environment; Glucose pulvis main component is glucose, for the respiratory raw material of most of microbe, the a small amount of glucose added in this agricultural chemicals is as saccharomycetic activation basic material, and after saccharomycete activation, the end product of decomposition glucose is carbonic acid gas and water, on environment also without impact; The Mixed Microbes added is the strong microorganism of selectivity, on environment also without impact.
3, noresidue: each component of agricultural chemicals, after medication, is all decomposed by the microorganisms or is absorbed by plants, without secondary products, microorganism when without also can natural death when parasitic source, to plant noresidue.
4, high efficiency: the present invention kills aphid mainly through the parasitization of white muscardine fungi and green muscardine fungus, belong to Biocidal method, meanwhile camphorating, mentioned microorganism can be assisted to colonize in smoothly in aphid body after ash leachate, thus reach the object of efficient killing aphids.
