摘要
为明确湘西州烟区种植绿肥的适宜还田量，研究了箭舌豌豆不同还田量对烤烟农艺性状、经济性状及烟叶物理特性、化学成分的影响。结果表明：绿肥翻压还田能提高烤烟农艺性状和经济性状，适宜的还田量能提高烟叶物理特性，促进烟叶化学成分协调。研究认为湘西州烟区绿肥还田量在20000-30000kg·hm-2较适宜，以绿肥还田量22500kg·hm-2最佳。
The effects of different amount of green manure returned to field on agronomic traits, economic traits, leaves＂ physical characteristics and chemical composition of flue-cured tobacco were studied by field experiment. The results showed that returning green manure could improve the agronomic traits, economic traits of flue-cured tobacco; suitable amount of green manure could improve leaves＂ physical characteristics and chemical composition of flue-cured tobacco. It considered that the 20 000 -30 000 kg· hm-2 of manure returning was more appropriate, the 22 500 kg· hm-2 of manure returning was best.
