摘要 [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。

Abstract [Objective] To research the suitable nitrogen application amount for new varieites (lines) of fluecured tobaccos cultivated in southern Anhui Province. [Method] With variety K326 as the control, test was carried out on the the nitrogen application amount for three new varieites (lines) of fluecured 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 design. [Result] FYV13, Anyan 2 and K326 showed better comprehensive performance in 120 kg/hm2 nitrogen treatment;while Anyan 1 showed better comprehensive performance in 105 kg/hm2 treatment. Differences between the four varieties (lines) were significant. Comprehensive performance of FYV13 was better than those of Anyan 1, Anyan 2 and K326. Among them, Anyan1 and Anyan 2 had similar comprehensive performance, which were better than that of control K326. [Conclusion] This research provides theoretical basis for the largescale extension of varieites (lines) FYV13, Anyan 1 and Anyan 2.

品種在烤烟生产中起着非常重要的作用[1],不同的品种具有不同的产质量潜能[2],这种潜能的发挥与该品种所种植的生态条件和栽培措施有关,而施氮量是栽培措施中非常重要的因素[3-4],肥力的多少直接影响着烤烟的生长发育、经济性状和内在品质[5-6]。鉴于此,该研究在皖南烟区进行试验,研究不同施氮量对烤烟主要植物学性状及农艺性状、经济性状、产量、原烟外观质量的影响。
