为了研究烤烟新品种湘烟3号和湘烟4号在湖南烟区的生态适应性及配套施肥技术,在株洲茶陵县以K326为对照品种进行了品种示范试验。结果表明:从生育期、农艺性状、抗病性及经济性状等综合指标来看,湘烟3号的大部分指标均超过了对照品种或与对照相似,综合评价较高;在试验所设的施肥水平下,产量品质较为稳定,其中以10 kg/667 m2的施氮水平最适宜,烤后原烟产量为145.43 kg/667 m2,产值达2 722.45元/667 m2,上等烟比例42.41%,上中等烟比例为95.9%;该品种适宜在湖南地区推广种植。而湘烟4号大部分经济性状指标低于对照品种K326,建议继续进行示范试验。
In order to study the ecological adaptability of Fanyan 3 and Xiangfan 4 in Hunan tobacco area and the matching fertilization techniques, a variety demonstration experiment was conducted in Kuling County of Zhuzhou. The results showed that most indexes of Xiangyan No.3 were more than those of the control varieties or similar to the control, and the comprehensive evaluation was high. According to the comprehensive indexes of growth period, agronomic traits, disease resistance and economic traits, Under the fertilization level, the yield and quality were stable. Among them, nitrogen fertilizer application rate of 10 kg / 667 m2 was the most suitable, yield of roasted tobacco was 145.43 kg / 667 m2, output value was 2 722.45 yuan / 667 m2, the ratio of superior tobacco was 42.41% , The proportion of medium-sized tobacco is 95.9%; the variety is suitable for planting in Hunan. However, the index of most economic traits of Xiang 4 was lower than that of the control K326, and it is suggested to continue the demonstration experiment.
