Three-dimensional biological control method for plant diseases and insect pests of tobacco planting
The invention discloses a three-dimensional biological control method for plant diseases and insect pests of tobacco planting. The three-dimensional biological control method has the advantages that the technological methods of plant essential oil, natural enemy insect releasing, insect sex attractants, solar insecticidal lamps, champak board trapping and killing and the like are combined to achieve three-dimensional control over the pests in the tobacco planting process, and the control effect on tobacco black shanks, tobacco brown leaf spots and myzus persicae is excellent; organic chemical pesticides are not needed to be used for controlling the pests in tobaccos, using of chemicals is greatly reduced, influences of the chemicals on the quality of the tobaccos are reduced, and pollution to the environment is reduced. 1. A tobacco plant pests three-dimensional biological method for preventing and treating, characterized in that the method comprises the following steps: Preventing fungus diseases, disease monitoring, pest control; for prevention and treatment of the fungus diseases including soil treatment, the foliage. 2. Tobacco cultivation method for preventing dimensional biological pests and diseases according to Claim 1, characterized in that the stated pest control comprises the following steps: the release of natural enemy insects; trapping harmful insects. 3. Tobacco cultivation method for preventing dimensional biological pests and diseases according to Claim 2, characterized in that the disease monitoring comprises the following steps: detecting spore catching use of tobacco daejon in pathogenic bacteria, the laboratory pathogenicbacteria of the types and quantity, and then draw up tobacco plant disease control strategy. 4. Tobacco cultivation method for preventing dimensional biological pests and diseases according to Claim 3, characterized in that the soil treatment comprises: in tobacco seedling transplant the daejon 12-15 days, the thyme essential oil, chamomile essential oil mixed after dilution add 1300-1500 times of the intermediate to the tobacco, tobacco use each strain 300 ml essential oil diluent; the foliage including: in tobacco seedling transplant the daejon 22-30 days, the thyme essential oil, chamomile essential oil mixed after dilution add 1000-1200 times tobacco leaf sprayed, using ethereal oil diluent per mu 30-40kg. 5. Tobacco cultivation method for preventing dimensional biological pests and diseases according to Claim 4, characterized in that the natural release of the insect comprises the following steps: (1) when the tobacco seedlings after transplant to the field, is placed in the tobacco field with stiff aphis blade, each week 600 head stiff aphis /mu, sustained 2-3 week, for the successful states the stiff aphis parasitic stiff aphis granarium virus; (2) placing stiff aphis 2-3 times, stop placed stiff aphis , release virus cheng Feng of the detached, the detached per week cheng Feng release virus 400 head/mu, sustained 3-4 week. 6. Tobacco plant pests according to Claim 5 three-dimensional biological method for preventing and treating, characterized in that the trapping harmful insects comprising the following steps: (1) when the tobacco seedlings after the transplantation, the tobacco daejon in placing each mu 6-8 a yellow, 6-8 plurality of blueboard; (2) when the tobacco seedlings after transplant to the field, is the tobacco daejon each mu 1 table solar disinsecting lamp; (3) when the tobacco seedlings after transplant to the field, is the tobacco daejon each mu 2 borne trap a, the sex of the borne trap includes insects, said insect sex attractant includes active material: cis-9-hexadecenoic acetate, cis-9-sixteen carbon olefine aldehyde , chitosan oligosaccharide. 7. Tobacco cultivation method for preventing dimensional biological pests and diseases according to Claim 6, characterized in that in the insect sex: cis-9-hexadecenoic acetate, cis-9-sixteen carbon olefine aldehyde , the weight ratio of chitosan oligosaccharide 2-7.5: 3.5-8.5 the [...] 1-1.5. 8. Tobacco cultivation method for preventing dimensional biological pests and diseases according to Claim 7, characterized in that the thyme essential oil and chamomile essential oil mass ratio is 1.3-1.4 the [...] 2.7-3.2.
