摘　　要：为确定不同熟期油菜品种的适宜播期,以早熟品种"1358"、中熟品种"中双11号"和晚熟品种"浙双8号"为材料,在长沙地区进行分期播种试验。结果表明:早熟油菜品种"1358"具有很好的耐迟播性,适宜的播期为10月中下旬;中晚熟品种在4个播期内均以9月30日和10月15日播种的产量最高,适播期为9月下旬到10月上中旬。In order to determine the suitable sowing date of rapeseed varieties with different mature period, an interval so- wing experiment was conducted with early-maturing variety ＂1358＂, medium-maturing variety ＂Zhongshuang No. 11＂ and late - maturing variety ＂Zheshuang No. 8＂ as materials in Changsha region. The results showed that the early - matu- ring variety ＂1358＂ had good resistance to late sowing, and its suitable sowing date was middle and late October. The highest yield of medium - and late-maturing varieties was gained in 30th September and 15th October, so their suitable sowing date was from late September to early and middle October.
