摘要
以云烟99为试验材料,探索了不同氮素水平(施纯氮3.65、4.25,4.85,5.45,6.05 kg/667m^(2))对烟株农艺性状、烟叶干物质累积及钾含量的影响。结果表明:施纯氮5.45 kg/667m^(2)能改善各时期烟株的农艺性状,并在团棵期、旺长期和成熟期提高烟株干物质积累量以及烟叶、烟株和初烤烟叶中的钾含量。
Using Yunyan 99 as material,the effects of various nitrogen levels(pure nitrogen 54.75,63.75,72.75,81.75,90.75 kg/hm^(2))on the agronomic characteristics,dry matter accumulation and potassium content of tobacco were studied.The results showed that T3(pure nitrogen 81.75 kg/hm^(2))could significantly improve the agronomic characteristics of tobacco plants at each growth stage,increase the dry matter accumulation of tobacco plants at the resettling and root-extending stage,vigorously growing stage and maturity stage,and raise potassium content in tobacco leaves,plants and raw flue-cured tobacco.
