Abstract
Yunyan 85,a flue-cured tobacco variety,was fertilized with different nitrogen amounts and sources to study the effects on its growth,yield and quality.The results showed that the agronomic characters,leaf area index,chlorophyll content,photosynthetic rate,yield and quality reduced with the disease of nitrogen amount,lower nitrogen amount(4.0kg/667m2) was not beneficial to plant growth,yield and quality of Yunyan 85,the mixed organic and inorganic nitrogen could obviously promote growth of Yunyan 85 compared with only organic nitrogen or inorganic nitrogen under the same nitrogen amount.The optimum application amount of nitrogen for the highest economic benefit of Yunyan 85 was 5.2kg/667m2 pure nitrogen(4.2kg/667m2 inorganic nitrogen + 1.0 kg/667m2 organic nitrogen)in the experiment.
