Abstract
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.
