| 摘 要： | 目的]研究钾肥用量对油菜产量、生物学特性及钾肥利用效率的影响。方法]以零水平为对照,设置9个钾肥用量水平,在云南9个不同生态类型的油菜产区组织3次重复的单因素随机区组联合大田试验。结果]云南油菜适量施用钾肥能够提高籽粒产量,钾肥用量为150-180kgK2O/hm2时,油菜产量可达到3983-4151kg,比K0对照增产4.7%-9.1%,并在K165处理处出现产量峰值;每施用K2O1kg,可增加油菜籽粒产量559kg,纯利润达到1229元/hm2,产投比达到1:1.95,钾肥偏生产力达到31.32kg/kgK2O,钾肥农学利用率达到3.7kg/kgK2O;施钾可促使油菜健壮生长,具有增果实、增粒、促进籽粒充实的作用。结论]云南油菜钾肥高产高效生产的适宜推荐范围为150-180kg K2O/hm2。但综合考虑产量和效益等因素,云南省适宜K2O施用量在73.9kg/hm2左右,陇川、玉龙和临翔产区及条件类似产区应适当增加到100kg/hm2左右较为合理。
