摘要
通过在不同海拔的油莱种植区域内安排田间试验，采用随机区组排列，分析播期与苗龄对油研10号产量的影响。结果表明，海拔高度不同，油研10号获得高产时播期的时间和苗龄的天数都有所不同。不同海拔地区的不同播期对油研10号的最终产量结果影响很大，增产达极显著水平；而不同的苗龄对油研10号的植株群体和个体，结果也表现出很大的差别，对后期产量的影响很大。根据油研10号在3个不同海拔的油莱种植区域内获取高产可得出：播期在高海拔（1200m以上）油菜种植区域为9月10日左右；中海拔（750～1000m）油菜种植区域为9月15日左右；低海拔（750m以下）油菜种植区域为9月20日前。苗龄控制在30～35d。
The field experiments of rape planting were conducted via random block rank in different altitudes. The effects of seeding date and seeding age were analyzed on yield of Youyan No. 10. The results showed that the seeding date and seeding age varied in different altitudes to achieve high yields. Various seeding date makes the significant contribution to the ultimate output and various seeding age also plays an important role in the communities and individuals of Youyan No. 10. According to the high yield results in 3 rape-planting regions of different altitudes,the seeding date is about on September 10 in the high altitudes（morn than 1 000 meters） ,September 15 in medium altitudes（750 - 1 000 meters）, September 20 in low altitudes （less than 750 meters） and the seeding age ranges from 30 to 35 days.
