Abstract: Using Yunyan 87 as the experimental variety, the fertilizer efficiency comparison test was carried out in Xia village, Yimen town, Huili county, Liangshan prefecture. The results showed that the new leaf fertilizer had no significant effect on botanical characters and main growth period of flue-cured tobacco, but had obvious effect on agronomic characters （stem circumference, leaf area, plant height）. After applying leaf fertilizer, the stem circumference, plant height and leaf area of flue-cured tobacco were larger than those of conventional fertilization control （CK2）; There were significant differences in total sugar between upper, middle and lower leaves of flue-cured tobacco, but there were no significant differences in total nitrogen, nicotine, chlorine and potassium between flue-cured tobacco leaves and CK2, which could improve the quality of flue-cured tobacco leaves but not significantly, and could increase the yield, the output value and the proportion of middle and upper class tobacco leaves.

Key words: new leaf fertilizer, tobacco, growth and development, yield, quality
