摘要
[目的]为提高江西烟叶质量、彰显江西烤烟风格特色、提高烟叶工业可用性提供理论依据。[方法]通过大田试验,研究了不同饼肥用量和施氮量对烤烟农艺性状、根系干重、经济性状、烟叶外观质量和烟碱含量的影响。[结果]在目前施肥水平(142.5 kg/hm2)基础上减少施氮量,可以有效改善烟叶外观质量和中上部烟碱;在同等施氮量(131.25 kg/hm2)的基础上,增施饼肥可以改善烟株的农艺性状、经济性状,提高烟叶的外观品质,协调烟叶的烟碱含量。[结论]在4个处理中,总体以施氮131.25 kg/hm2,穴施450 kg/hm2饼肥效果最佳。
[ Objective] The research aimed to provide the theoretical basis for the improvement of the quality of Jiangxi flue-cured tobacco leaves, manifesting the style and characteristics of Jiangxi flue-cured tobacco, and the improvement of the industrial availability. [ Method ] The effects of different application amounts of secdcake fertilization and nitrogen fertilizer on the agronomic characters, root dry weight, eco- nomic traits, appearance quality and nicotine content of tobacco leaves were studied. [ Result ] Decreasing nitrogen fertilizer application a- mount under the current fertilization level （ 142.5 kg/hm^2 ） could effectively improve appearance quality of tobacco leaves and the nicotine content in middle and upper leaves, increasing seedcake fertilization at the same level of fertilization （ 131.25 kg/hm^2 ） could improve the ag- ronomic characters and economic characters of tobacco plants, enhance the appearance quality and harmonize the content of nicotine of tobacco leaves. [ Conclusion] Among 4 treatments,when 131.25 kg/hm^2 nitrogen in total and 450 kg/hm^2 seedcake fertilization in small holes were applied, the result was the best.
