| 摘要: |
| 选取5个油菜品种,连续2年在合肥巢湖市进行了不同收获时间及不同收获方式(联合收获、分段收获)的菜籽含油量及蛋白质含量的测定。结果表明:在适收期前后4~5天内所有试验品种菜籽的含油量及蛋白质含量稳定性均大于95%;方差分析可知收获方式对多数品种的菜籽含油量和蛋白质含量影响不显著,但中双11对收获方式和收获时间则较为敏感;同时也出现分段收获比联合收获的菜籽含油量低,含蛋白质量高的普遍现象。因此大部分油菜品种在适收期内不管采用联合收获还是分段收获,菜籽含油量及蛋白质含量保持稳定。 |

| Abstract: |
| In order to understand the effects of different harvest periods and methods on the oil and protein contents of rapeseed, five rapeseed varieties were chosen as materials and directly seeded in Hefei, Anhui province for two years.The rapeseeds were harvested at different time points during the suitable harvest periods by combination and two-stage harvesting methods separately.The results showed that rapeseed oil and protein contents were not changed significantly before and after 4-5 days during suitable harvest periods, and the stabilization was over 95%.Harvest methods influenced oil and protein content, but the effect was not significant for most varieties of rapeseed except zhongshuang11.Although harvest methods had no significant influence on oil and protein content, it provided a change trend that the oil content of combine harvest rapeseed was a little lower than two-stage harvest rapeseed.The oil and protein contents in rapeseed maintained stable when it was harvested during suitable periods. |
