为了探讨烟草新品系YX012在湘南植烟区的特征特性,2014年在湖南省常宁市以K326和云烟87为对照,进行了对比试验。结果表明,与对照K326和云烟87相比较,从株叶型、农艺性状、经济性状和烟叶的外观质量等综合因子看,YX012表现最好。其植株较高(103.7 cm),茎围最大(9.5 cm),节距最大(5.13 cm),有效叶适中,单叶重适宜,单产较高,达185.7 kg/667m2,产值最高,达4 410.8元/667m2(按照当年收购价),中上等烟比例较大,为97.1%。
In order to explore the characteristics of tobacco new line YX012 in southern Hunan tobacco planting areas, comparative tests were conducted in 2014 in Changning, Hunan with K326 and Yunyan87 as control. The results showed that compared with the control K326 and Yunyan 87, YX012 showed the best performance in terms of plant leaf type, agronomic traits, economic traits and appearance quality of tobacco leaves. The plant was higher (103.7 cm) and the stem was the largest (9.5 cm) with the largest pitch (5.13 cm). The effective leaves were moderate and the single leaves were suitable. The yield was 185.7 kg / 667m 2 and the highest value reached 4 410.8 Yuan / 667m2 (according to the purchase price of the year), a larger proportion of upper-middle-class smoke was 97.1%.
