Effects of Complexed Application of Rapeseed Cake and Compound Fertilizer on Quality and Yield of Tobacco

This study explored the effects of rapeseed cake as the base fertilizer and different application time of compound fertilizer on yield and quality of tobacco.The results indicated that rapeseed cake and the tobacco compound fertilizer together used as base fertilizer,compared with only rapeseed cake used as base fertilizer and the rapeseed cake used as the base fertilizer first,the tobacco compound fertilizer used after transplanting 30 d the growing situation in the field was better.The chlorophyll comparative content,net photosynthetic rate,water use efficiency,the yield and production value were also higher.The chemistry coordination was also relatively better.
