摘　　要：2006～2007年连续两年采用烤烟-绿肥轮作田间试验与室内分析方法,研究绿肥还田对土壤培肥和烤烟产量、品质的作用,取得良好效果。绿肥还田明显提高土壤有效磷钾养分含量。土壤速效磷以油菜区>黑麦草区>CK;土壤速效钾以黑麦草区>油菜区>CK。绿肥还田显著提高烟叶产量,改善烟叶品质。黑麦草区、油菜区分别比对照烟叶增产13.7%、16.4%,上、中等烟叶比例达90%以上。With tobacco-green manure crop rotation field experiments and indoor analysis for two consecutive years from 2006 to 2007,the effects of returning application of green manure on soil fertility and the yield and quality of tobacco were investigated and the good results were achieved.Green manure return to field could significantly improve the contents of soil phosphorus and potassium.The soil phosphorus content changed in order of the rape ryegrass CK,and soil potassium content changed in order of ryegrass rape CK.Green manure return to field could significantly increase tobacco yield and improve the quality of tobacco.The tobacco yield of ryegrass and rape were respectively 13.7% and 16.4% higher than that of CK,and the ratios of top-tobacco and middle-tobacco in manure treatments reached 90 percent.
