烤烟新品种鄂烤2号的适宜施氮量研究

Study on Suitable Nitrogen Amount of Flue-cured Tobacco Variety Ekao No.2

2015年和2016年,对湖北省自育的烤烟新品种鄂烤2号在清江流域和环神农架地区设点试验,探讨了不同氮肥施用量对其农艺性状、经济性状和品质性状的影响。结果表明,鄂烤2号施氮量在环神农架地区以82.5~90.0 kg/hm^2为宜,在清江流域以90.0~97.5 kg/hm^2为宜,其产量、产值、均价、上等烟率和上中等烟率相对较高,化学成分适宜,感官质量表现较好。

In2015and2016,new flue-cured tobacco variety Ekao No.2from Hubei province were demonstrated inQingjiang area and around Shennongjia area,and the effects of different application rate of nitrogen fertilizer on agronomictrait,economic character and quality traits of Ekao No.2were investigated.The results showed that,the application rate of nitrogen fertilizer with82.5-90.0kg/hm2around Shennongjia area and90.0-97.5kg/hm2in Qingjiang area were appropriate for Ekao No.2,and the yield,output value,average price,the proportion of top tobacco and medium leal tobacco was relatively higher,the contents of main chemical components were hannonious,and the quality of tobacco sensoiy evaluation was better.
