为了探寻适合贵州市贵定县烟区地膜井窖式烟苗移栽的最佳烟苗素质,比较了不同素质烟苗地膜井窖式移栽对烤烟生长发育及烟叶质量的影响。结果表明,适合当地的地膜井窖式小苗移栽最佳烟苗素质要具备剪叶1~2次、苗龄45-60 d、茎高4~8 cm、功能叶4~7片/株。该结果为当地全面推广烤烟地膜井窖式移栽提供了技术支撑。
In order to explore the best tobacco seedling quality suitable for the transplanting of cellar tobacco seedlings in the tobacco planting area of Guoding County, Guizhou Province, the effects of mulching cellar transplanting with different quality tobacco seedlings on the growth and the quality of flue-cured tobacco were compared. The results showed that the best quality of seedlings for cellar seedlings transplanting should be cut 1-2 times a year, 45-60 days seedling age, 4-8 cm stem height and 4-7 functional leaves per plant. The results provide a technical support for the local popularization of tobacco film cellar transplanting.
