摘　　要：以云烟87中等施氮水平为对照,研究新引烤烟品种云烟207适宜的施氮水平。结果表明:与云烟87相比,当施氮水平为75~105 kg/hm^2时,云烟207整体生长势强,经济性状较好,烟叶外观质量综合指数提高4.2%,但化学成分协调性稍欠且生育期延迟。综合来看,在保障正常生长发育和烟叶产质量的基础上,以施氮量105.0 kg/hm^2左右较有利于云烟207在曲靖烟区的优质适产。Taking Yunyan 87 as the contrast, suitable application nitrogen levels of new flue-cured tobacco variety Yunyan 207 was studied. The results showed that, compared with Yunyan87, the growing of Yunyan 207 was stronger, and the economic traits were better,tobacco leaves appearance quality index increased by 4.2%. However, the chemical composition of the coordination was less impressive,and growth period was longer. Illustrating N application around 105.0 kg/hm2 is conducive and high-quality for Yunyan 207 which can get a good economic characters and improve tobacco leaves quality on the basis of normal growth and development.
