摘　　要：为改变河北蔚县烟区传统施肥方法,明确适宜的施肥量,为卷烟工业企业提供稳定优质的原料,以龙江911烤烟品种为材料,进行了不同氮磷钾施用量对烤烟生长发育和产质量的影响。结果表明,不同施肥量对烤烟生长发育、化学成分和经济性状有显著的影响;不同施肥量主要在烟株的旺长期对株高和茎围发挥作用,叶数不受影响;烟碱含量和氮肥施用量呈正相关,化学成分总体呈高糖低碱状态。结合经济性状的表现,河北蔚县烟叶最佳施肥组合为施用纯氮52.5 kg/hm^(2)、P 2O 552.5 kg/hm^(2)、K 2O 157.95 kg/hm^(2)。With the flue-cured tobacco variety Longjiang 911 as the material,the study was conducted on the effects of different application rates of nitrogen,phosphorus and potassium on the growth and production quality to change the traditional empirical fertilization method in Yuxian County,Hebei Province,define the appropriate fertilization rate,and provide stable and high-quality raw materials for the cigarette industry.The results indicated that different fertilization rates had significant effects on the growth and development,chemical composition and economic characteristics of flue-cured tobacco;different application rates mainly played their roles in plant height and stem girth during the flourishing stage of tobacco plants,and the number of leaves was not affected;nicotine content was positively correlated to the application rate of nitrogen fertilizer,and the overall chemical composition took on status of high glucose and low alkalinity.In combination with the performance of economic traits,the optimal fertilization combination for tobacco leaves in Yuxian County,Hebei was equivalent to 52.5 kg/hm^(2)of pure nitrogen,52.5 kg/hm^(2)of P 2O 5 and 157.95 kg/hm^(2)of K 2O.
