烤烟新品种云烟85在安徽烟区的主要性状表现

于1999年对皖北烟区5个市(县)种植的烤烟新品种云烟85的产量、质量和抗病性进行了调查,并与当地的当家品种NC89进行了比较.2001年又调查了不同饼肥用量对云烟85的产量和质量的影响.结果显示:云烟85的产量与NC89相当,产值比NC89增加1069.95～4080.00元/hm2,均价和上等烟比例也都高于NC89,均价增幅为0.48～1.20元/kg,上等烟比例增幅为2.0～17.0个百分点,其原烟外观质量、化学成分和评吸鉴定结果均优于NC89;增加饼肥用量能够进一步改善云烟85的烟叶质量.云烟85抗黑胫病能力比NC89强,但对气斑病和烟草脉斑病的抗性较差,在生长前期有畸型株发生.因此,在生产中应增施磷钾肥以减轻气斑病的危害,并适当增加饼肥的用量以提高烟叶质量,同时要加强烟草脉斑病的预防和蚜虫防治工作.

Main Character of Tobacco Variety--Yunyan 85 in Anhui

The yield,quality and resistance of new flue-cured tobacco variety-Yunyan 85,which was planted in 5 cities(counties)of northern Anhui and NC 89,dominant variety in 1999,was used as CK,were investigated.The influence on yield and quality under the condition of different application amount of cake fertilizer was investigated in 2001.The results indicated that the yield of Yunyan 85 nearly equaled to NC 89's; its productive value increased 71.33～272.0 yuan/hm 2 more than NC 89's; rate of slap-up tobacco leaves was higher than NC 89's and so was its average price that increased 0.48～1.20 yuan/kg,the rate of slap-up tobacco leaves increased 2.0～17.0 percent; the complexion of its leaves,the chemical component and the smoking result outclassed NC 89.The tobacco leaves quality of Yunyan 85 could be improved by increasing the application amount of cake fertilizer.Yunyan 85 has stronger resistance to black shank,but its resistance to weather-fleck and PVY was weak.Some abnormal plants were found in earlier growth period.Therefore,phospho-potash fertilizer should be increased in order to increase the resistance,the amount of cake fertilizer should be properly increased to improve the quality and the prevention and cure to PVY & aphids must be intensified.
