| 摘 要： | 目的]研究不同施肥模式对旱区春油菜（Brassica napusL.）生长特性的影响,为旱作区春油菜高产高效生产提供技术支撑。方法]针对青海省旱区春油菜种植中常规农户施肥存在的问题,设计了高产高效、再高产和再高产高效3种施肥模式,并设常规农户施肥模式和不施肥为对照。其中,高产高效施肥模式为：基肥,129.00 kg/hm2N＋90.00 kg/hm2P2O5＋55.50 kg/hm2K2O＋1 260.00 kg/hm2有机肥。再高产施肥模式为：基肥,103.50 kg/hm2N＋90.00 kg/hm2P2O5＋55.50 kg/hm2K2O＋1 260.00 kg/hm2有机肥＋0.540 kg/hm2硼肥＋11.100 kg/hm2硫肥;追肥,34.50 kg/hm2N。再高产高效施肥模式为：基肥,151.50 kg/hm2N＋75.00 kg/hm2P2O5＋45.00 kg/hm2K2O＋1 695.00 kg/hm2有机肥＋0.036 kg/hm2硼肥＋0.740 kg/hm2硫肥。再高产高效施肥模式采用的种植方式为垄膜沟植,其他施肥模式及对照采用露地种植。结果]与常规农户施肥模式和不施肥处理相比,3种施肥模式下春油菜的有效分枝能力较强,角果数增多,千粒重相对较高,产量和水分利用效率增加显著;与常规农户施肥模式相比,高产高效、再高产和再高产高效3种施肥模式增产率分别为13.10%、25.00%和30.95%,水分利用率分别增加9.31%、25.24%、48.77%。结论]在旱作区,对常规农户施肥模式进行调整,通过平衡施肥可以充分发挥作物施肥的增产潜力。
