徽县烤烟新品种适应性研究

Study on the Adaptability of New Varieties of Flue-cured Tobacco in Hui County

为筛选出适宜徽县烟区生态条件的烤烟新品种,在徽县烟区以秦烟96为对照,对2个烤烟品种云烟99、云烟100的生物学性状、抗病性、经济性状、外观质量进行了观察分析。试验结果表明,云烟99经济性状表现最好,产值(51829.93元/hm^2)和均价(22.83元/kg)最高;株型为腰鼓型,主脉稍粗,大田生长势强、整齐一致,分层落黄好,性状稳定,易烘烤,原烟外观质量好;较对照的发病率和病情指数低,抗病性较强。初步确定云烟99适宜在徽县烟区推广种植。

In order to screen out new flue-cured tobacco varieties suitable for the ecological conditions of tobacco-growing areas in Hui county,the biological characteristics,disease resistance,economic characters and appearance quality of Yunyan 99 and Yunyan 100 were investigated and analyzed compared with the control of Qinyan 96.The results showed that the economic performance of Yunyan 99 was the best,and its output value(51829.93 yuan/hm^2)and average price(22.83 yuan/kg)were the highest.The Yunyan 99 plant was a waist drum type,the main vein was slightly thick,the field growth was strong,uniform,the layering was good,the traits were stable,easy to bake,and the appearance quality of the original smoke was good,its incidence and disease index were lower,and the disease resistance was stronger than that of CK.It is preliminarily determined that Yunyan 99 is suitable to popularize and plant in the tobacco area of Hui county.
