| 摘 要： | 采用田间试验,于2010年在湖南龙山研究了不同氮肥施用量对K326烤烟品种的生长发育、产质量及抗病性的影响.结果表明:随着氮肥用量的增加,K326的长势越好,烟叶产量也越高,但其产值随施氮量的增加呈现先升后降的趋势,总的来看,施氮量以98.25kg/hm2时产值最高,而氮肥用量对烤烟的抗病性没有明显影响.

| Abstract: | Field experiment of tobacco variety K326 was implemented under 5 different N application amount levels in Longshan county of Hunan Province in 2010.The results showed that tobacco grew better and the yield also increased with the increasing of N application amount.However,output value showed a raising-decreasing state with increasing of N application amount.Generally,it was optimal for tobacco variety K326 when N application amount was 98.25 kg/hm2,and N application amount showed no relation with resistance of flue-cured tobacco. |
