安徽自育烤烟新品种(系)在皖南适宜施氮量的筛选

Screening of Suitable Nitrogen Application Amount for New Varieites( Lines) of Flue-cured Tobacco Cultivated in Southern Anhui Province

[目的]研究安徽自育烤烟新品种(系)在皖南的适宜施氮量。[方法]以K326为对照,采用裂区设计对烤烟新品种(系)FYV13、安烟2号和安烟1号进行了不同施氮量的试验,考察不同施氮量对其主要植物学性状、农艺性状、经济性状、产量、原烟外观质量的影响。[结果]FYV13、安烟2号和K326以120 kg/hm2氮处理综合表现较好;而安烟1号以105 kg/hm2氮处理综合表现较好。4个品种间差异显著,FYV13综合表现好于安烟1号、安烟2号和K326,安烟1号和安烟2号综合表现相近,好于对照K326。[结论]该研究为烤烟新品种(系)FYV13、安烟2号、安烟1号的大面积推广提供理论依据。

[Objective ] To research the suitable nitrogen application amount for new varieites （ lines ） of flue-cured tobaccos cultivated in southern Anhui Province. [ Method] With variety K326 as the control, test was carded out on the the nitrogen app｜ication amount for three new varieites （lines） of flue-cured tobacco, which were FYV13, Anyan 1 and Anyan 2. Effects of nitrogen application amount on the major botanical characters, agronomic characters, economic chracters, yield and appearance quality of raw tobacco were investigated by split plot de- sign. [Result] FYV13, Anyan 2 and K326 showed better comprehensive performance in 120 kg/hm- nitrogen treatment; while Anyan 1 showed better comprehensive performance in 105 kg/hm2 treatment. Differences between the four varieties （lines） were significant. Compre- hensive performance of FYV13 was better than those of Anyan 1, Anyan 2 and K326. Among them, Anyanl and Anyan 2 had similar compre- hensive performance, which were better than that of control K326. [ Conclusion] This research provides theoretical basis for the large-scale ex- tension of vafieites （lines） FYV13, Anvan 1 and Anvan 2.
