采用油菜早熟品种C868、202研究其播种期对产量和产量构成的影响。结果表明,10月10日、20日和30日3个播种期的产量差异显著,以播种期为10月10日的产量最高,其次是播种期为10月20日。因此,湘中及以北地区的早熟油菜在10月20日之前播种可获得较高的产量。

The paper studies the effect of different sowing date on rape yield and its component with the early maturing vari- ety of rape C868 and 202. The result was shown as follow：there was significant difference of rape yield among three sowing date with 10th October,20th October, and 30th October,the highest yield was the sowing date with 10th October, and the next was 20th October. Consequently, the paper suggested that suitable sowing date of early maturing rape in the region of mid ＆ northern in the Hunan province was before 20th October, which...
