(2) Organic fertilizer could decrease the sugar content of themiddle and upper leaves, reduce the total nitrogen and nicotine content of upper leaves, improve the quality oftobacco, organic fertilizer could make its chemical composition tend to be more coordination, more consistent the requirements of highquality tobacco. (3) Organic fertilizer could improve the ratio of upper-tobacco leaves, improve tobacco yieldand value, the yield was increased by 3.2%~10.85%, the value was increased 937.95~12598.2 yuan/hm2.
