Embodiment 1

[0016] Flue-cured tobacco intercropping experiment

[0017] Test site: Impression Tobacco Village, Shilin County, Yunnan Province

[0018] The experiment was divided into two groups: flue-cured tobacco single cropping area; flue-cured tobacco and sweet basil intercropping area. The soil and terrain conditions of the two groups of test sites are similar, with an area of ​​about 1 mu.

[0019] (1) Flue-cured tobacco monoculture area

[0020] Tobacco seedlings were transplanted in mid-May, and a row of flue-cured tobacco was planted in each ridge. The width of the ridge was 1.2m, and the distance between plants was 0.5m. No pesticide was applied, and fertilization was carried out according to conventional management methods.

[0021] (2) Intercropping area of ​​flue-cured tobacco and sweet basil

[0022] The sweet basil is transplanted at the end of April, and the tobacco seedlings are transplanted 20 days later. Plant according to the "1+1" pattern, and plant a row of sweet ...

Abstract

The invention discloses a method using sweet basil to control flue-cured tobacco plant diseases and insect pests. The method includes the steps of changing a monoculture method of flue-cured tobaccos, firstly transplanting the sweet basil 20 days before transplanting of the flue-cured tobaccos, and planting one row of sweet basil and one row of flue-cured tobaccos. Through adoption of growth habit difference between the sweet basil and the flue-cured tobaccos, the sweet basil has specific aromatic odor, and volatile constituents of the rosemary have a bactericidal effect and can eliminate the plant diseases and insect pests. In addition, the sweet basil is less in the plant diseases and insect pests, so the sweet basil can enable the incidence of the plant diseases and insect pests of the flue-cured tobaccos to be reduced. Through intercropping between the sweet basil and the flue-cured tobaccos, the method can be used for controlling occurrence of various plant diseases and insect pests of the flue-cured tobaccos, reducing usage amount of pesticide, and achieving the purposes of maintaining ecological balance and reducing insect control cost.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of flue-cured tobacco diseases and insect pests, and in particular relates to a method for controlling flue-cured tobacco diseases and insect pests by using sweet basil. Background technique [0002] Flue-cured tobacco is one of the important economic crops in our country. In the production process of flue-cured tobacco, tobacco diseases and insect pests are common problems affecting its growth. Chemical pesticides are the most commonly used methods in production practice. However, with the promotion of organic tobacco planting, no pesticides are required in the production process of flue-cured tobacco. Therefore, how to reduce the impact of diseases and insect pests on flue-cured tobacco without using pesticides is a key issue. Problems we need to solve. [0003] Sweet basil is a 1-year herbaceous plant belonging to the genus Ocimum of Lamiaceae. The whole plant has a strong fragr...
