环神农架地区烤烟施肥技术研究

Study on Balanced Application Technique of Tobacco Around Shennongjia Area

为给环神农架地区烤烟生产中的施肥提供理论参考，在环神农架地区2003--2008年烤烟施肥问题的相关试验资料及调查结果搜集整理的基础上，分析了该地区烤烟施肥上存在的主要问题，并结合试验与调查结果提出：环神农架地区烤烟氮肥用量应控制在82．5～97．5kg／hm^2，氮、磷、钾比例以1：1．2：3为宜，应重视有机肥和微肥的合理施用。

The main problem in tobacco application was analyzed based on summarizing the relative test data and investigation results in tobacco application from 2003 to 2008 around Shennongjia area. The paper puts forward the nitrogen application amount is 82.5 to 97.5 kg/hm^2, the appropriate ratio of nitrogen, phosphorus and potassium should be 1 ： 1.2 ： 3 and the organic and micro-element fertilizer should be reasonably used in tobacco cultivation around Shennongjia area.
