Effects of Spraying Ti Fertilizer on Leaf Surface on Growth,Development and Quality of Burley Tobacco
Year: 2011
Type: article
Abstract: 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.
