摘  要:[目的]以玉溪烟区连作多年的植烟土壤为研究对象,探究不同品种绿肥掩青对植烟土壤理化性质及后茬烤烟生长、产量和品质的影响,为玉溪烟区连作烟田的土壤保育确定最佳冬种绿肥种类提供参考依据。[方法]设置田间随机区组排列试验,于前茬烤烟收获后开展肥田萝卜、大麦、光叶紫花苕、黑麦草及冬闲对照5种田间小春种植模式,于下茬烤烟种植前90 d收割、掩青,探讨不同绿肥翻压对土壤理化性状及烤烟生长、产量和品质的影响。[结果]与冬闲田对照相比,不同绿肥品种掩青对土壤容重的影响不明显,肥田萝卜掩青下土壤pH的降幅较大,禾本科绿肥大麦掩青对提高土壤有机质含量最优,豆科绿肥光叶紫花苕对水解氮和有效磷有较好的促进作用;0~10 cm土层,禾本科绿肥黑麦草掩青对提高土壤有效钾效果较好,10~20 cm土层,大麦则对土壤有效钾有更好的促进作用;4种绿肥对烤烟生长发育均有不同程度的促进作用,其促进效果为大麦>黑麦草>光叶紫花苕>肥田萝卜,大麦掩青还田后的烤烟田间长势相对较好、根系活力最优,烟叶产量最高、化学成分更为协调,评吸质量更佳,与对照相比其产量、产值分别提高15.2%、19.7%,钾含量提高了22%,评吸总得分提高了6.56%。[结论]不同绿肥种植和掩青改善了连作烟田土壤理化性状,有效培肥土壤,优化土壤环境,对促进烤烟根系生长发育,增加植株干物质,提高烟叶产量、产值效果明显,尤其以大麦种植掩青效果更为显著。[Objective]Taking the continuous tobacco soil in Yuxi tobacco area for many years as study object,the influence of different varieties of green fertilizer turning over on the physical and chemical properties of soil and the growth,yield and quality of the flue-cured tobacco was explored,which provided a reference for the soil conservation of the continuous tobacco field in Yuxi area.[Method]A field randomized block arrangement experiment was conducted to carry out five field planting patterns,including radish,barley,Vicia villosa,ryegrass and winter fallow,after the previous flue-cured tobacco harvest.The harvest and green cover were conducted before the next flue-cured tobacco planting to explore the effects of different green manure tillage on soil physical and chemical properties and the growth,yield and quality of flue-cured tobacco.[Result]Compared with the control of winter fallow field,the effect of different green manure varieties on soil bulk density was not obvious.The soil pH in the fertile field decreased greatly under the cover of radish.Barley,the green manure of gramineous family,was the best for improving the content of soil organic matter.Vicia villosa,the green manure of leguminous family,had a better promotion on hydrolyzed nitrogen and available phosphorus.In 0-10 cm soil layer,the ryegrass had maximum available potassium increment,and in 10-20 cm soil layer,barley had better promoting effect on available potassium.Four kinds of green manure could promote the growth and development of flue-cured tobacco to varying degrees,with the promotion effect order of barley>ryegrass>vicia villosa>radish.The flue-cured tobacco field after barley covering green and returning to the field had relatively good growth momentum,the best root activity,the highest yield of tobacco leaves,more coordinated chemical composition,better smoking quality.The yield and output value increased by 15.2%and 19.7%,the potassium content increased by 22%,and the total score of sensory evaluation increased by 6.56%,respectively,
