摘　　要：采用叶面喷施钛肥的方法,研究了不同的喷施时期对白肋烟生长过程中田间农艺性状、调制后的物理特性及化学成分的影响,结果表明:喷施钛肥能够提高烟株大田生育期间的干物质积累速率,改善白肋烟的田间农艺性状,提高调制后烟叶的填充值、单叶重和厚度,减小叶片的长宽比和含梗率;改善了烟叶化学成分的协调性,提高烟叶含糖量、糖碱比、氮碱比和钾氯比,降低烟碱含量。综合分析表明在白肋烟打顶当天叶面喷施钛肥,最有利于白肋烟生长发育及其品质的提高。Through spraying titanium（Ti） fertilizer on the leaf surface of Burley tobacco plants,the effects of different spraying dates on the field agronomic traits,the physical properties and major chemical compositions of flue-cured leaves of Burley tobacco were studied.The results indicated that spraying Ti fertilizer on the leaf surface could enhance the dry matter accumulation rate of tobacco plants in the whole growth period in the field,improve its field agronomic traits,increase the filling value,single-leaf weight and leaf thickness after being modulated,reduce the length-width ratio and stem content of leaves,improve the harmony of the main chemical compositions of tobacco leaves,increase the sugar content,sugar-nicotine ratio,nitrogen-nicotine ratio and potassium-chlorine ratio in tobacco leaves,and decrease the nicotine content.Synthetic analysis indicated that spraying Ti fertilizer on the leaf surface on the day of topping was most beneficial to the improvement of the growth,development and quality of Burley tobacco.
