Embodiment 1

[0016] Flue-cured tobacco intercropping test

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

[0018] The experiment is divided into two groups: the flue-cured tobacco monoculture area; the flue-cured tobacco and lavender intercropping area. The soil and topography of the two groups of test sites are comparable, with an area of ​​about 1 mu.

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

[0020] Transplanting tobacco seedlings in mid-May, planting a row of flue-cured tobacco per ridge, ridge width 1.2m, plant spacing 0.5m, do not apply any pesticides, fertilize according to conventional management methods.

[0021] (2) Flue-cured tobacco and lavender intercropping area

[0022] Lavender transplanting time is mid-April, and tobacco seedlings will be transplanted 30 days later. Plant according to the "1+1" model, plant a row of lavender and then plant a row of flue-cured tobacco. Lavender ridge width is 0.5m, plant spacing is 0.3m; flue-cured tobacco ridge wi...

Abstract

The invention discloses a method using lavender 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 lavender 30 days before transplanting of the flue-cured tobaccos, and planting one row of lavender and one row of flue-cured tobaccos. Through adoption of growth habit difference between the lavender and the flue-cured tobaccos, the lavender has specific aromatic odor, and volatile constituents of the lavender have a bactericidal effect and can eliminate the plant diseases and insect pests. In addition, the lavender is less in the plant diseases and insect pests, so the lavender can enable the incidence of the plant diseases and insect pests of the flue-cured tobaccos to be reduced. Through intercropping between the lavender 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 flue-cured tobacco diseases and insect pests control, and specifically relates to a method for controlling flue-cured tobacco diseases and insect pests by using lavender. Background technique [0002] Flue-cured tobacco is one of the important economic crops in my country. In the production process of flue-cured tobacco, tobacco diseases and insect pests are universal problems that affect its growth. In production practice, more methods are used to prevent and control chemical pesticides. However, with the promotion of organic tobacco planting, it is required not to use pesticides in the production process of flue-cured tobacco. Therefore, how to reduce the impact of pests and diseases on flue-cured tobacco without applying pesticides? The problem we need to solve. [0003] Lavender belongs to the genus Lavender of the Lamiaceae family. It was a very common vanilla in Roman times. It was called "after vanilla" ...
