摘　　要：为明确绿肥作物在改良土壤和提高肥力方面的作用,通过3年田间定位试验,研究了不同种类绿肥多年翻压对植烟土壤理化性状的影响。结果表明,3年翻压绿肥的土壤容重降低1.71%-23.87%,土壤有机质、全氮、全磷、全钾、碱解氮、速效磷和速效钾含量（质量分数）分别提高3.73%-8.76%,1.40%-3.50%,31.37%-38.24%,1.24%-5.15%,1.50%-23.70%,660.98%-833.72%和335.83%-783.75%,土壤p H整体变化不大。禾本科绿肥尤其是冬牧70对土壤容重和有机质含量的影响较大,豆科绿肥对土壤全氮、全磷、全钾、碱解氮、速效磷、速效钾含量的影响较大,其中光叶紫花苕对土壤全氮和全磷含量影响最大,紫云英对土壤全钾、碱解氮、速效磷、速效钾含量影响最大。To clarify the function of green manure crops in soil improvement and fertility increasing, the effects of different green manure crops ploughing back on the physical and chemical properties of tobacco planting soils were studied with a field experiment at fixed locations. The results showed that after green manure ploughing back for 3 consecutive years, soil bulk density reduced by 1.71%-23.87%, and the contents of organic matter, total N, total P, total K, alkaline hydrolytic N, available P, available K in soil increased by 3.73%-8.76%, 1.40%-3.50%, 31.37%-38.24%, 1.24%-5.15%, 1.50%-23.70%, 660.98%-833.72%, 335.83%-783.75%, respectively; the pH of soil did not change greatly in general. Gramineous green manure, especially Dongmu-70 Rye, affected soil bulk density and organic matter content obviously; leguminous green manure affected the contents of total N, total P, total K, alkaline hydrolytic N, available P, available K in soil obviously, notably Vicia villosa affected the contents of total N and total P in soil and Milk vetch affected the contents of total K, alkaline hydrolytic N, available P and available K in soil more significantly.
