摘要
研究表明，烤烟施肥方法的不同显著影响烟株生长发育动态和烟叶品质；烤烟施肥技术还具有明显的地域性。在皖北烟区，采用一次性单行条施全部氮肥易于导致在旺长前地上部分生长过旺，烤后下部叶前后半片厚度差异明显。若在烤烟生长前期供水充足，肥料淋溶损失严重，肥效降低，大田后期明显无后劲。而氮肥采用基施与追施相结合，基肥采用单株定量环穴施肥，并与剪叶育苗技术、“移栽旱地培土”技术相配套，更利于提高烟叶品质，烟叶内在总糖、烟碱等主要成份达到了目前消费需求的指标。
The effect of available nitrogen level in soil after transplant on tobacco leaf growth,development and quality,was obvious. There was an obvious endemicity in fertilizer practice in different ecological environment. In the north of Anhui,total nitrogen fertilizer applied at transplanting with the 'One band'method increase slightly early tobacco leaf growth and the differences in thickness between the base and the top of the lower leaves cured.If more water for the crop in five weeks after transplanting was supplied the losses of nitrogen increased,and fertilizer efficiency reduced.The combination method of nitrogen fertilizer application including the basal dressing and the topdressing was good for leaf quality and,total sugar and nicotine content in leaf was fit for consumer's needs.
