摘要
研究了播期对油菜"两优586"生育、产量及抗性的影响。结果表明:在江西宜春,"两优586"的最佳播期为10月8日,适宜播期为10月1日～10月15日,产量可达1792.50～1929.75kg/hm2,生育期适中(190d左右),单株有效角果数较多,为345个左右,且抗性较强,发病率低于15%,倒伏率低于10%。
The effects of sowing date on the growth, yield and resistance of rapeseed 'Liangyou586' were studied. The results indicated that in Yichun city the best sowing date for 'Liangyou 586' was October 8th, and the proper sowing date was from October 1st to October 15th. When 'Liangyou 586' was sown at above proper dates, it had higher yield (1 792.50～1 929.75kg/hm2), moderate growth and developmental duration (190 days or so), more effective pods per plant (about 345) and stronger resistance (the incidence of disease below 15%, the lodging rate under 10%).
