腾冲市北部烟区蚕豆前作烤烟氮肥减施试验

Experiment of reducing nitrogen fertilizer application on flue-cured tobacco in former broad bean in the tobacco-growing areas in the north of Tengehong City

对于蚕豆前作的烟田土壤,如按常规用量进行施肥,则易导致肥力过足,影响烟叶品质。为探究蚕豆前作烟田的适宜施肥量,在云南省腾冲市开展试验,共设置7个施肥处理,结果表明T1处理减氮10%的综合表现最佳,在生育期、农艺性状、烤后烟叶的外观品质、经济性状等方面均有稳定表现。
