摘　　要：以云烟87为材料,研究了翻压不同生物量的光苕对植烟土壤性状的影响。结果表明:翻压光苕可提高土壤水解氮、速效磷、速效钾、有机质的含量,翻压量越多,效果越明显。土壤微生物数量也随光苕翻压量的增加而不同程度的增加。在该试验的条件下,光苕翻压的生物量在18 000 kg/hm2左右时效果相对较好。In order to reveal the effects of different model of Vicia villosa green manure turning under on soil improvement. Taking Yunyan 87 for material, we used the method of field test of Vicia villosa green manure and inorganic fertilizer, and study on the effect of different biomass of Vicia villosa green manure turning under on soil improvement. The results showed that Vicia villosa green manure turning under can improve the content of hydrolysable nitrogen, available phosphorus, available potassium and organic matter in soil, and the effects are significantly and it increased withed the amount of green manure turning under. The amount of microorganism in soil were improved with the adding of amount of turning under. From the plant growth, economic benefit improving and tobacco growing soils modified angle, the amount of Vicia villosa green manure turning under which was controlled about 18 000 kg/hm^2 is comparatively better.
