1988年采用土培和田间试验结果表明,在本试验条件下,施用钾肥不仅能促进烟草生长发育,提高烟叶产量,还能改善烟叶内在及外观品质,主要体现在烟叶中钾、可溶性糖含量和施木克值及中上等烟比例等均明显提高,但不同种类钾肥对烤烟的生长发育,产量及外观品质的效应均无显著差异,仅炳叶中氯离子含量随氯化钾用量的增加而上升,K_2O/Cl~-比例则随之而降低。
The results of soil culture and field experiments in 1988 showed that under the experimental conditions, the application of potassium fertilizer can not only promote the growth and development of tobacco, increase the yield of tobacco leaves, but also improve the intrinsic and appearance quality of tobacco leaves, mainly in the content of potassium, soluble sugar and The value of Shi Mukai and the ratio of middle and upper tobacco were significantly increased, but the effect of different types of K fertilizer on the growth, yield and appearance quality of flue-cured tobacco had no significant difference, only chloride content in Bingbing with the increase of potassium chloride However, the ratio of K2O / Cl ~ - decreases.
