摘　　要：研究了不同施氮水平对华烟06的农艺性状、化学成分、产量、产值的影响。结果表明,增加施氮量可以促进华烟06的株高、叶片数、最大叶面积等农艺性状的生长,但施氮量过多效果并不明显;淀粉、可溶性总糖含量随施氮量的增加而下降,烟碱含量随施氮量的增加而升高;化学成分及协调性表现为中部叶以中、高氮水平较适宜,上部叶以低氮较适宜;产量、产值和均价则以中氮处理最好。从农艺性状、化学成分等综合比较来看,新品系华烟06在清远烟区的适宜施氮量为165 kg/hm2。Effects of different nitrogen levels on agronomic characters, chemical compositions, yield and production values of Huayan06 were studied. The results showed that plant height, number of leaves and the biggest leaf area were promoted under increasing nitrogen, but effects were not obvious under too much nitrogen. Contents of starch and total soluble sugar decreased with adding nitrogen, but that of nicotine increased. Chemical compositions and coordination of middle leaves under middle or high nitrogen were suitable, but those of upper leaves were suitable under low nitrogen. The yield, production values and average price were best under middle nitrogen. From comprehensive comparison of agronomic characters and chemical compositions, the suitable nitrogen of the new variety Huayan06 in Oinavuan was 165 kg/hm2.
