摘要:

探究施氮量和种植密度对烤烟大竖把直把种子油产量及脂肪酸成分的影响,为降低种子油成本提供栽培技术参考。本研究采用裂区试验设计,在3个施氮量(90.0、135.0、180.0 kg·hm-2)和3个种植密度(18 180、22 230、27 780株?hm-2)条件下比较了烤烟大竖把直把的农艺性状、种子产量性状、种子油产量以及种子油脂肪酸成分。结果表明,烤烟大竖把直把的农艺性状受施氮量影响,种子产量、种子油产量总体上随施氮量和种植密度的增加而增加,不同处理的种子油脂肪酸成分一致,但含量略有差异。要获得高产优质的大竖把直把种子油,其最佳施肥量为纯氮180.0 kg·hm-2,种植密度27 780株·hm-2,此时种子产量达2 325.15 kg·hm-2,种子油产量达962.60 kg·hm-2,且总脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸、亚油酸、油酸含量都处于较高水平。

Abstract:

This study aimed to investigate the effects of nitrogen application rate and planting density on seed oil yield and fatty acid composition of flue-cured tobacco Dashubazhiba,providing cultivation technical references for reducing the cost of its seed oil. A split-plot design was adopted,and the agronomic traits,seed yield traits,seed oil yield,and fatty acid composition of the seeds were compared under three nitrogen application rates(90.0,135.0,180.0 kg·hm-2)and three planting densities(18 180,22 230,27 780 plants per hectare). The results showed that the agronomic traits of Dashubazhiba were affected by nitrogen application rate,while seed yield and seed oil yield increased with increasing nitrogen application rate and planting density. The fatty acid composition of seed oil remained consistent across different treatments,but their contents showed slight variations. To obtain high-yield and high-quality seed oil of Dashubazhiba,the optimal nitrogen application rate was 180.0 kg·hm-2 and planting density was 27 780 plants per hectare. Under these conditions,seed yield reached 2 325.15 kg·hm-2,seed oil yield reached 962.60 kg·hm-2,and the contents of total fatty acids,monounsaturated fatty acids,polyunsaturated fatty acids,linoleic acid,and oleic acid were all at relatively high levels.

Key words: seed oil yield, nitrogen application rate, planting density, fatty acid, tobacco
