摘　　要：以‘云烟85’为参试品种,研究随着打叶数量的逐渐增多,烤烟的综合性状所呈现的不同规律。结果表明,株高、节距、叶片长宽、单叶重均与打叶数成正相关,随着打叶数量的逐渐增加,茎围、产值、上等烟比例均呈现先升高后降低二次曲线的变化规律。综合分析认为,云南省广南县以打掉下部3片底脚叶和上部1片顶叶的处理,产量稳定,等级质量结构最优,产值最高。This experiment took ＇Yunyan 85＇ as the tested flue-cured tobacco variety, the removed leaf number were studied with the gradually increasing, the comprehensive characters of flue-cured tobacco by showing the different rules. The result showed that, plant height, leaf length and width, pitch, single leaf weight were related with removed leaf number. With the removed leaf number gradually increasing, stem girth, output value and proportion of high grade leaves showed increased first and then decreased as the two curve equation. Integrated various factors were derived that the handle of removed the lower 3 and upper 1 leaves of flue-cured tobacco in Guangnan of Yunnan Province showed stable yield, quality grade of the structure optimization, maximum output value.
