摘　　要：采用田间小区试验的方法探讨了施用70%化肥条件下不同光叶紫花苕子翻压量对烤烟生长发育以及烟叶产量、产值和化学成分含量的影响。结果表明,翻压适量的绿肥能够促进烟株的生长,尤其是叶片的开片;增加烟叶的SPAD值;提高烟株干物质积累量及烤后烟叶的产量,改善烟叶的化学品质。当翻压22 500 kg/hm2绿肥时,烟叶的产量、产值和上等烟比例最高,分别比常规施肥对照处理增加了14.9%、12.5%和25.0%,烟叶中、下部叶的钾含量以及中、上部叶的烟碱含量明显增加,其化学成分协调性与常规施肥对照处理相当。总之,在施用70%化肥的条件下,翻压绿肥量以22 500 kg/hm2为宜。Field experiment was carried out to study the effect of different burying amount of Vicia Villosa on growth, yield, quality and chemical composition of flue-cured tobacco when applying 70% chemical fertilizer. The result showed that burying green manure could promote tobacco plant growth, especially leaf development, increase leaf SPAD value, improve dry matter accumulation and leaf yield, and improve tobacco chemical quality. When burying green manure at rate of 22 500 kg/ha ,the leaf yield, economic value and ratios of first-class leaf were the highest, and compared with the control, which were respectively increased by14.9%, 12.5% and 25.0%. K content of middle leaf and low leaf, and nicotine of top leaf and middle leaf obviously increased, The harmony of chemical composition equaled the control. It suggested that burying green manure at this rate was advisable when applying 70% chemical fertilizer.
