Embodiment 1
[0045] Embodiment 1 A kind of planting method that improves flue-cured tobacco yield and quality
[0046] Tobacco and garlic are intercropped and planted 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 monoculture), the killing effect of garlic root exudates on the virus in tobacco field soil was analyzed.
[0047] 1. Experimental materials
[0048] Common tobacco (flue-cured tobacco) variety K326 was provided by our laboratory. The variety of garlic (Allium sativum) is white garlic, a plant of the lily 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). Sow healthy flue-cured tobacco seeds and garlic seeds in he...
Embodiment 2
[0124] The flue-cured tobacco and garlic seedlings were transplanted to the field. The variety of garlic is purple garlic. Plant flue-cured tobacco in rows, and plant 2 rows of garlic for every 2 rows of flue-cured tobacco. The distance between two adjacent rows of flue-cured tobacco (row spacing) is 0.8m, and the distance between two adjacent flue-cured tobacco plants (plant distance) in each row of flue-cured tobacco is 0.7m. The distance between each row of garlic and the adjacent row of flue-cured tobacco is 0.3m. The distance between two adjacent rows of garlic is 24cm, and the distance between two adjacent plants of garlic in each row is 32cm. No pesticides are applied during the growth of the tobacco plants, and the moisture content of the tobacco field soil is kept at 63%. The remaining operations are equivalent to field tobacco leaf production.
[0125] This example can simultaneously and effectively kill the TMV, CMV and PVY viruses in the soil of the tobacco fie...
Embodiment 3
[0127] The flue-cured tobacco and garlic seedlings were transplanted to the field. The variety of garlic is white garlic. Plant flue-cured tobacco in rows, and plant 2 rows of garlic for every 3 rows of flue-cured tobacco. The distance between two adjacent rows of flue-cured tobacco (row spacing) is 0.7m, and the distance between two adjacent flue-cured tobacco plants (plant distance) in each row of flue-cured tobacco is 0.8m. The distance between each row of garlic and the adjacent row of flue-cured tobacco is 0.4m. The distance between two adjacent rows of garlic is 25cm, and the distance between two adjacent plants of garlic in each row is 25cm. 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.
[0128] This example can simultaneously and effectively kill the TMV, CMV and PVY viruses in the soil of the tobacco fiel...
