摘要
经过连续的肥料试验表明，氮、磷、钾用量对产量作用的主效应为N＞K＞P，对产值影响的主效应为K＞P＞N。在皖西中等肥力的土壤上，烤烟适宜的氮肥用量为82．5-97．5kg/hm2，N:P2O5：K2O为1：1．2：2～2.5。
The continuous fertilizer tests showed that the main effect of the amounts of N, P andK manure for the yield and ontpat value of the flue-curred tobacco was N>K>P and K>P>N,respectivity. The west part in Anhui,the proper level of N manure was 82. 5~97. 5kg/hm2,theproportion f N, P2O5 and K2O was 1: 1. 2: 2~2. 5.
