摘要:
中、上等烟叶量和烟叶化学成分是反映烤烟品质的二个主要的方面.打顶时期和单株留叶数是影响烤烟品质的主要农艺因素.现蕾和现蕾前打顶留20叶,中、上等烟叶率稳定在80%左右;现蕾和现蕾前打顶,增施氮肥提高中、上等烟叶量.烟叶中烟碱和糖的含量可变性较大,全氮、钾等含量可变性较小.打顶早、留叶数较少时.烟碱和全氮含量较高;留叶较多时增施氮肥,有使烟碱含量增高趋势.含糖量以现蕾打顶处理的较高,与施氮量、密度不呈相关趋势.早打顶、较少留叶可提高烟叶含钾量.本试验条件下.N(90)水平现蕾留20叶打顶为烤烟优质丰产优化组合.
Abstract:
The weight of middle-superior leaves and the composition of chemical material are two principal indicators of the leaf quality in flue-cured tobacco. The main factors influencing the weight of middle-superior leaves are the topping time and the leaf number. The steady percentage of middle-superior leaves was about 80% when topped in budding with 20 leaves. The content of nicotine showed variability and the total nitrogen varies less with the various topping time and leaf number. The content was higher with earlier topping and less leaf number. The content of sugar was higher by topping in budding but not showed correlation with the nitrogen applied or plant population. It showed higher coment of potassium with earlier topping and less leaf number. The results showed that the best benifit was provided by N90-20 leaves and topping at budding.
