摘要
盆栽试验和大田试验的结果证明;叶面喷洒烟草多效灵,能够明显促进烟草生长,提高烟草光合性能,改善烟叶内在化学成份,使上中等烟叶比例、单叶重、均价、级指提高,从而显著地增加烟草产量,明显地改善烟叶品质,提高经济效益.
The results of the green house and field experiments on tobacco nutritive andvigorous solution(TNVS)research show that foliar application of TNVS obv-iously improves the growth,photosynthetic property and chemical componentsof tobacco,and heightens the weight,grade,price and grade index of tobaccoleaves.As a result,both the yield and the economic effectiveness of flue-curedtobacco are significantly increased.
