摘　　要：为探讨河池烟区种植云烟202最佳施氮量,研究了不同氮肥水平对云烟202生长发育、经济性状、内在质量的影响。结果表明:当氮肥施用量在75.0kg/hm2和112.5kg/hm2水平时有利于烟株生长发育,当施用量在75.0kg/hm2和37.5kg/hm2水平时烟叶品质较优。云烟202在河池烟区适宜的氮肥施用水平为75.0kg/hm2。In order to find the optimum nitrogen fertilizer rate on tobacco variety Yunyan202 in Hechi region, the effects of different rate of nitrogen fertilizer on the growth, yield and quality of Yunyan202 were studied. The results showed that the application levels of nitrogen at 75.0kg/hm^2 and112.5kg/hm^2 could enhance the growth and yield of tobacco plants; the application levels of 75.0kg/hm^2 and112.Skg/hm^2 could improve the quality of tobacco leaves. Therefore, the suitable application level of nitrogen was 75.0kg/hm^2 for Yunyan202 in Hechi region.
