摘　　要：连续3年采用绿肥-烟-稻轮作田间定位试验与室内分析相结合的方法,研究绿肥还田对提高土壤肥力和烟叶产量、品质及后茬作物晚稻产量的作用,取得良好效果。绿肥还田其养分释放可明显提高土壤速效氮磷钾养分含量,促进烤烟植株对土壤养分的吸收利用,显著提高烟叶产量。且改善烟叶品质,其烟叶外观表现为结构疏松,成熟度好,光泽强,颜色均匀,杂色少。3年结果统计,黑麦草区烟叶平均产量为2644kg/hm2,油菜区烟叶平均产量为2626kg/hm2,分别比对照增产14.6%、14.1%。上、中等烟叶比例分别为92.1%、93.6%,烟叶内在化学成分接近或达到优质烟叶标准。后茬作物晚稻分别比对照增产43.2%、29.6%。Continuously three years usage of the method which unifies the Green Manure-Tobacco-Paddy Rice Crop Rotation Field Localization Experiment and the Room Analyzes, we researched green manure return field＇ s abilities to enhance the soil fertility, the leaf tobacco yield quality and the latter-stubble late rice yield and obtained good effects. The green manure return field＇ s nutrient release significantly enhanced the soil available nutrient of nitrogen phosphorus potassium nutrient content, promoted flue-cured tobacco adult plant＇ s absorption of soil nutrient, and increased the leaf tobacco yield. Moreover, it improved leaf tobacco quality, made its appearance of loose structure, good maturity, strong gloss, even color and little variedness. Three years statistics showed the perennial ryegrass area leaf tobacco average yield was 2644 kg/hm2, the rape area leaf tobacco average yield was 2626 kg/hm2, and the productions were 14.6% and 14.1% higher than comparison, respectively. There were 92.1% and 93.6% of high and medium leaf tobacco, respectively. The leaf tobacco intrinsic chemical composition closed or achieved the high quality leaf tobacco standard. The latter-stubble late rice productions were 43.2% and 29.6% higher than comparison, respectively.
