Embodiment 1

[0047] Embodiment 1 A kind of method for comprehensive prevention and control of various tobacco diseases

[0048] Tobacco and mint are intercropped in fields with high incidence of viral diseases. The contents of TMV, CMV and PVY in tobacco strains were detected by realtime fluorescent quantitative PCR (realtime fluoresce quantitative polymerase chain reaction, q-PCR) technology. Compared with the control group (non-intercropping, tobacco monocropping), the killing effect of peppermint root exudates on the virus in tobacco field soil was analyzed.

[0049] 1. Experimental materials

[0050] Common tobacco (flue-cured tobacco) variety K326 was provided by our laboratory. The species of mint is spearmint, a plant of the Labiatae family. Purchased from Lvyong Seedlings Co., Ltd., the selection of materials refers to the "Dictionary of Chinese Medicine" (edited by Jiangsu New Medical College, 1975). Healthy flue-cured tobacco seeds and peppermint seeds were sown in healthy su...

Embodiment 2

[0124] The flue-cured tobacco and mint seedlings were transplanted to the field. The variety of flue-cured tobacco is Cuibi No. 1. The variety of mint is peppermint. The flue-cured tobacco is planted in rows, and 2 rows of mint are planted for every 2 rows of flue-cured tobacco. The distance between two adjacent rows of flue-cured tobacco (row spacing) is 1.5m, and the distance between two adjacent flue-cured tobacco plants (plant distance) in each row of flue-cured tobacco is 0.6m. The distance between each row of mint and the adjacent row of flue-cured tobacco is 0.4m, and the distance between two adjacent mint plants in each row of mint is 25cm. The cultivation density of flue-cured tobacco is controlled at 1000 plants / mu. No pesticides are applied during the growth of the tobacco plants, and the moisture content of the tobacco field soil is kept at 65%. The remaining operations are equivalent to field tobacco leaf production.

Embodiment 3

[0127]The flue-cured tobacco and mint seedlings were transplanted to the field. The variety of flue-cured tobacco is Honghua Dajinyuan. The variety of mint is peppermint. The flue-cured tobacco is planted in rows, and 2 rows of mint are planted for every 3 rows of flue-cured tobacco. The distance between two adjacent rows of flue-cured tobacco (row spacing) is 1.0m, and the distance between two adjacent flue-cured tobacco plants (plant distance) in each row of flue-cured tobacco is 0.2m. The distance between each row of mint and the adjacent row of flue-cured tobacco is 0.2m, and the distance between two adjacent mint plants in each row of mint is 20cm. The cultivation density of flue-cured tobacco is controlled at 1000 plants / mu. No pesticides are applied during the growth of the tobacco plants, and the moisture content of the tobacco field soil is kept at 70%. The remaining operations are equivalent to field tobacco leaf production.

Abstract

The invention discloses a method for comprehensively controlling various cigarette diseases. By means of the beneficial allelopathy of mint and flue-cured tobacco, diseases and insect pests are effectively reduced, the soil physical and chemical properties can be effectively improved, the soil fertility is regulated, the continuous cropping barrier can be weakened, on the premise of not damaging the farmland ecological environment and the existing planting function, the morbidity and damage degree of tobacco TMV, CMV and PVY can be remarkably lowered, meanwhile, the yield and quality of flue-cured tobacco are improved, and the method is ecologic, safe and free of toxin and contamination; in addition, intercropping of mint and flue-cured tobacco can sufficiently utilize land, the total value of crops is increased, the income of farmers is increased, the planted mint can also be used for extracting essential oil or being adopted as mint seasonings and the like, and remarkable social benefits, ecological benefits and economic benefits are achieved. The method is easy to implement, economical and not high in management technology requirement, and has the good application and popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation. Specifically, it relates to a method for comprehensive prevention and control of various tobacco diseases. Background technique [0002] In recent years, the occurrence of tobacco virus diseases is on the rise, seriously affecting the quality and yield of tobacco leaves. Reduce the income of tobacco farmers and reduce their enthusiasm for growing tobacco. Tobacco field soil carrying virus is one of the main ways of transmission of tobacco virus disease. The chemical disinfection method commonly used in agriculture is likely to cause soil salinization and aggravate soil compaction. It is of great significance to develop green and environment-friendly toxic soil remediation technology in production. [0003] In human production activities, farmland soil is often polluted by various toxic and harmful substances, such as: pesticide pollution, crude oil pollution, pathogenic microorgan...
