Abstract
A field experiment was carried out in the Southwest of Hubei to study the effect of green manure and nitrogen levels on nutrient accumulation and quality of tobacco.The results showed that overturning vetch markedly promoted N,P,K absorption by tobacco,increased vegetative yield of tobacco,and improved fertilizer efficiency.Yield and production value could markedly be decreased under overturning wheat and reducing nitrogen 45.0 kg per ha.Overturning green manure accelerated K content of top leaf and below leaf by 0.20 percentage point and 0.16 percentage point,decreased K content of middle leaf by 0.15 percentage point.K content of tobacco by overturning vetch was higher than by overturning wheat.Overturning wheat reduced sugars contents of top leaf and middle leaf,and increased sugars content of below tobacco leaf.Overturning green manure improved tobacco quality,especially depressed the contents of nicotine and chlorine of top leaf and middle leaf,and increased K content.
