| 摘 要： | 土壤水分过多或过少均使烟叶的产量下降,水分过多使烟叶糖分含量增加,总氮和烟碱含量下降,干旱则使糖的含量下降,总氮和烟碱含量增加.土壤水分对k(+)、CI(-)的含量影响不显著.烤烟栽培中保持伸根、旺长、成熟各期土壤相对持水量为60%、80%、60%有利于产质的形成

| Abstract: | Excessive soil moisture and drought reduce yield. Excessive soil moisture produces flue-cured tobaccos of in-creased carbohydrate content and a lowered percentage of nicotine, total ni-trogen.drought produces flue-cured tobaccos of decreased sugar content and inereased nicotine, total nitrogen. Every phase, the shotrer period soil moisture treatment has no significant affects on K+ and cl- content.The soil moisture proper culturing are that, root elongation phase 60%, rapidly development phase 80%, ripening phase 60% |
