在天水市半干旱山区研究了不同播期对白菜型冬油菜品种天油8号生长及产量的影响，结果表明，随着播期的推迟，越冬率降低，成熟期提前，花期和生育期缩短；分枝数、单株有效角果数、角果长度、角粒重和千粒重逐渐减少。不同播种期间产量差异极显著，以8月22日播种的产量最高，为2486.62 kg/hm2，9月2日以后播种的减产显著。

The effect of Brassica napus variety Tianyou 8’s different sowing dates on its growing and yield was studied in the semi-arid mountainous regions of Tianshui city . The results shows that,with the delayed sowing,winter rate decreased,the early maturity, flowering and fertility shortening;The number of branches,pods per plant,pods length,pods grain weight and thousand kernel weight decreased . The yield difference is significant during the different sowing,the yield of August 22 is highest,reaches 2 486.62 kg/hm2,the yield of after the September 2nd decreased significantly.
