摘要
Abstract
To study the effect of nitrogen type and amount on the growth and quality of flue-cured tobacco, a field experiment was carried out in Guiyang county, Chenzhou city, in 2017. 7 nitrogen fertilizer types and dosage tests were carried out with Yunyan 87 as the material. The results showed that all nitrogen treatments compared with no nitrogen fertilizer treatment had better performance in plant height, maximum leaf length, width and maximum leaf area than those without nitrogen treatment. In the total sugar and reducing sugar, the trend from the lower leaves to the upper leaves increased first and then decreased. To a certain extent, the nitrogen application level increased the potassium level of tobacco leaves showed an upward trend. The change trend of potassium and chlorine in tobacco leaves was lower leaves＞ middle leaves＞ upper leaves. The level of nitrogen application was 90 kg·hm-2, and the proportion of upper middle class tobacco and yield of flue-cured tobacco increased significantly. There was no significant effect on the average price of tobacco leaf after baking. Compared with potassium nitrate, ammonium nitrate can improve the economic characters of flue cured tobacco leaves.关键词
