为明确郴州市桂阳县烟稻复种连作烟田中云烟 87 的适宜留叶数,设计留叶数 13～20 片的 8 个处理,研究了不同留叶数对烤烟农艺性状、叶面积指数、株型、干物质以及氮磷钾养分积累与分配的影响.结果表明:随着打顶留叶数的增加,烤烟株高增加,氮、磷积累量减少,叶面积指数、干物质积累量、钾积累量呈先增加后减少的趋势;留叶数 13～14 片的株型为短筒型,留叶数 15～18 片的株型为筒型,留叶数 19～20 片的株型为鼓型;留叶数过少会造成烟株矮小,影响中、下部烟叶发育;留叶数过多会降低烟田的叶面积指数,影响烟叶产量和品质.重点考虑烟株和烟叶的干物质量,认为在桂阳烟区稻茬烤烟云烟 87 的留叶数以 17...

This study aims to determine the appropriate number of leaves remained of'Yunyan 87'in the field with rice-tobacco rotation in Guiyang,Chenzhou,Hunan.Eight treatments with 13-20 leaves remained were designed.The agronomic traits,leaf area index(LAI),plant architecture,and accumulation and distribution of dry matter,nitrogen,phosphorus,and potassium of flue-cured tobacco in different treatments were measured,on the basis of which the optimum number of leaves remained was determined.The results showed that with the increase in the number of leaves remained,the flue-cured tobacco presented increa...
