Abstract: A field experiment was carried out to study the effects of three application rate of conventional specialty compound fertilizer for tobacco and three application rate of organic}norganic compound fertilizer on the growth,yield and quality of flue-cured tobacco. The results showed that reducing base fertilizer application have some influence on the growth yield and quality of tobacco. Compared to the conventional nitrogen application rate treatments,the leaf number in the day before harvest decreased 1一2 pieces, the maximum leaf width and the maximum leaf area in the day before harvest decreased 9%一11%and 9%一31%,the yield, output value and commercial grade of flue}ured tobacco decreased 3%一9%, 5%一10 % and 1%一4%,respectively, in the reducing base fertilizer application treatments. Compared to the conventional amount of N,the amount of total sugar and reducing sugar decreased 1%一22% and 2%一23 %,respectively , in the reducing base fertilizer application treatments;The organic}norganic compound fertilizer treatments have advantages in the agronomic characters,chemical quality, out-put value and commercial grade of tobacco,compared to the conventional specialty compound fertilizer treatments.Compared to the conventional specialty compound fertilizer treatments,the leaf number in the day before harvest increased 2一3 pieces,the tobacco plant height and average leaf size in the day before harvest increased 12%一18% and 13%一14%,the content of petroleum ether extract increased 1%一15%,the yield,output value and commercial grade of flue}ured tobacco increased 4%一6%,6%一8 % and 3%一7%,respectively,in the organicgnorgan is compound fertilizer treatments. In conclusion comprehensive benefit in the yield,output value,the organic}norganic compound fertilizer could lead to a better and quality of tobacco,with less inorganic nitrogen input.

Key words: Organic-inorganic compound fertilizer, Tobacco leaf, Chemical quality
