不同打顶留杈方法对早花烟株产量及质量性状的影响

探讨不同打顶留权方法对早花烟株产量及质量性状的影响。以烤烟品种云烟97为材料，采取留权叶位与打顶方式双因子设计，打顶方式为扣心打顶、现蕾打顶和初花打顶，留权叶位为倒一叶、倒二叶和倒三叶，以不打顶作为对照（CK），共设10个处理。结果表明，现蕾打顶倒二叶留权烟株生长发育良好，平均产量、产值、均价、中上等烟比例最高，外观质量良好，化学成分更趋于协调，感官质量总分最高。现蕾打顶倒二叶留权有效降低早花对烟株的影响，是出现早花现象后对烟株产量和质量的有效弥补措施。...

Summary:探讨不同打顶留权方法对早花烟株产量及质量性状的影响。以烤烟品种云烟97为材料，采取留权叶位与打顶方式双因子设计，打顶方式为扣心打顶、现蕾打顶和初花打顶，留权叶位为倒一叶、倒二叶和倒三叶，以不打顶作为对照（CK），共设10个处理。结果表明，现蕾打顶倒二叶留权烟株生长发育良好，平均产量、产值、均价、中上等烟比例最高，外观质量良好，化学成分更趋于协调，感官质量总分最高。现蕾打顶倒二叶留权有效降低早花对烟株的影响，是出现早花现象后对烟株产量和质量的有效弥补措施。

flue-cured tobacco; premature flowering; topping; remaining branch
The effects of different method of topping and remainning branch on yield and quality character of premature flowering tobacco was studied. Test taking was flue-cured tobacco variety Yunyan 97, adopt the remaining branch leaf position and topping two factor design, topping at deduct heart topping, flower-bud appearing and early flowering topping, remaining branch leaf position leaf, two leaf was inverted, inverted trefoil, not topping as control, a total of 10 treatments. The results showed that squaring topping two remaining branch leaf tobacco plant growth was good, average yield, production value, average price, classy smoke scale maximum,
