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 lemongrass 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 between flue-cured tobacco and lemongrass

[0022] The lemongrass is transplanted in early May, and the tobacco seedlings are transplanted 10 days later. Plant according to the "1+1" pattern, that is, plant a row of lemongra...

Abstract

The invention discloses a cured tobacco pest and disease damage control method by means of cymbopogon flexuosus. Single cultivation method of cured tobacco is changed, the cymbopogon flexuosus are transplanted first 10 days earlier than cured tobacco transplanting, and the cymbopogon flexuosus and the cured tobacco are planted in lines in an alternate mode. Growth habit differences between the cymbopogon flexuosus and the cured tobacco are utilitzed, the cymbopogon flexuosus have a special fragrant smell, the volatile components of the cymbopogon flexuosus has an effect of sterilization and can drive away pest and disease damages, and pest and disease damages of cymbopogon flexuosus are small, and therefore the pest and disease damage incidence rate of the cured tobacco can be lowered. According to the cured tobacco pest and disease damage control method by means of the cymbopogon flexuosus, by means of interplanting of the cymbopogon flexuosus and the cured tobacco, occurrences of various pest and disease damages of the cured tobacco are controlled, the usage amount of pesticides is reduced, and therefore the purposes of keeping ecological balance and reducing pest control cost are achieved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco planting, and in particular relates to a method for controlling flue-cured tobacco diseases and insect pests by using lemon grass. 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] Lemongrass is a perennial herbaceous plant in the grass family. Fresh grass or dried plant leaves and stems have a strong lemon fragrance. Citronella grass is co...
