| 摘 要： | 目的]为探明不同基追比(基肥和追肥比例)氮肥形态对烤烟产质的影响。方法]在云南保山烟区,采用大田小区研究法,根据硝态氮和氨态氮在基肥和追肥中所占比例,设置6个处理,研究不同处理对烤烟农艺性状、经济性状及品质的影响。结果]就农艺性状、经济性状而言,处理T3(基肥硝态氮40%+铵态氮60%,追肥硝态氮60%+氨态氮40%)、处理T4(基肥硝态氮60%+氨态氮40%,追肥硝态氮40%+铵态氮60%)效果最好;就烟叶大量元素、微量元素而言,各处理间差异均不显著。结论]处理T3和T4有利于烤烟植株对矿质营养元素的吸收和干物质积累,内在化学成分较协调。

| Abstract: | Objective]The research aimed to study the effects of different nitrogen form ratio （ basic fertilizer and topdressing fertilizer） on yield and quality of flue-cured tobacco. Method]Field plot method was adopted in Baoshan tobacco growing area in Yunnan Province. According to the different proportions of the nitrogen forms（ the nitrate nitrogen and ammonia nitrogen） in the basic fertilizer and the topdressing,six different treatments were designed to research the effects on agronomic characters,economic characters and quality of flue-cured tobacco. Result]As far as agronomic trait and economic trait,the effects of the treatment T3 （ basic fertilizer： nitrate nitrogen 40% ＋ ammonium nitrogen 60% ,topdressing fertilizer： nitrate nitrogen fertilizer 60% ＋ ammonia nitrogen 40% ） and T4 （ basic fertilizer： nitrate nitrogen 60% ＋ ammonia nitrogen 40% ,topdressing fertilizer： nitrate nitrogen fertilizer 40% ＋ ammonium nitrogen 60% ） were the best. As far as major elements and trace elements in the tobacco leaves,there weren’t significant differences. Conclusion]The treatment T3 and T4 were benefit to the absorption of mineral nutrition elements and the accumulation of the dry matter in flue-cured tobacco,whose intrinsic chemical components were coordinated. |
