摘要
冬油菜在宁夏的抗寒性、越冬性及生产潜力研究表明：冬油菜在宁夏是可以安全越冬的，不同品种越冬返青率在72．5％-81．8％；陇油8号的产量最高，为2845．5kg／hm^2，其次为陇油6号，产量为2728．5kg／hm2。冬油菜复种的玉米、水稻等农作物可完全成熟，且可获得较高产量。冬油菜不同轮作模式实现了宁夏2年3茬作物收获，可充分利用自然资源，提高复种指数。冬油菜在宁夏具有广阔的发展前景。
Studies of cold resistance, overwintering and production potential of winter rape in Ningxia showed that： It can safely live through the winter. Over wintering rate of different species are 72.5%-81.8%. The yield of ＇Longyou No.8＇ is 2 845.5 kg/hm2,which is the highest among all, then followed by ＇Longyou No.6＇ with yield of 2 728.5 kg/hm2. Winter rape multiple cropping of corn, rice and other crops can be fully mature, and can get higher yield. Different rotation patterns of winter rape is achieved three-crops within two years in Ningxia, which can make full use of natural resources, increase multiple cropping index. Winter rape in Ningxia has a broad development prospects.
