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 flue-cured 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 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 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 large-scale extension of varieites (lines) FYV13,Anyan 1 and Anyan 2.
