川南烟区打顶方式对初烤烟叶产质量的影响
Effects of Topping Modes on Yield and Quality of Flue-cured Tobacco in Southern Sichuan
摘要
Abstract
To explore the reasonable tobacco group structure,effects of six topping modes on yield and quality of flue-cured tobacco were studied. The results showed that the topping mode on early flowering or full flowering period and 20~22 leaves were optimal under southern Sichuan ecoclimatic. Compared with the traditional method,the economic properties of flue-cured tobacco of optimization mode such as average price,the proportion of superior,output value were greatly improved;appearance quality was better;total sugar content increased by 27.8%,potassium content increased by 7.9%,nicotine content decreased by 20.46%,intrinsic chemical compositions were to coordinate;the aroma quality got purer,aroma quantity became more,and the use value increased.关键词
