[Method] The effects of different transplanting dates and transplanting methods on yield and quality of fluecured tobacco were studied by field plot experiment with K326 as the main cultivated variety. [Result] The transplanting method could advance the transplanting date of tobacco seedlings, and achieve the effects of benefiting the growth of tobacco plants, improving the economic characteristics of tobacco leaves, coordinating the chemical components, and improving the smoking quality of tobacco leaves. [Conclusion] Generally, it is appropriate to transplant tobacco seedlings on February 25 by the covered well celluar method.展开更多
