Study on Optimum Fertilization Mode for Burnt-sweet-aroma-style Flue-cured Tobacco
摘要
Abstract
The optimum fertilization mode for burnt-sweet-aroma-style flue-cured tobacco variety Yunyan 97 was studied through field test by adopting three-factor quadratic D-saturate optimal design.The results showed that the application rate of nitrogen,phosphorus and potassium fertilizer mainly affected the yield,output value and sensory quality of flue-cured tobacco.Under the condition that the output value exceeded 40000 yuna/hm2,the optimal fertilizer application rates were N 91.60～ 100.78kg/hm2,P2O5 177.40 ～ 193.17 kg/hm2,and K2O 212.38～ 247.75 kg/hm2.Under the condition that the score of sensory quality evaluation exceeded 75,the optimal fertilizer application rates were N 88.80～ 101.00 kg/hm2,P2O5 189.21 ～ 205.80 kg/hm2,and K2O 236.27 ～ 269.89 kg/hm2.Comprehensively considering the aroma-style characteristics and sensory quality of tobacco leaf,we thought that the optimum fertilizer application rates for burnt-sweet-aroma-style flue-cured tobacco in Yibin city of Sichuan province were N 91.60～100.78 kg/hm2,P2O5 189.21～ 193.17 kg/hm2,and K2O 236.27～247.75 kg/hm2.关键词
