[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。
[目的]研究鉀肥用量對油菜產量、生物學特性及鉀肥利用效率的影響。[方法]以零水平為對照,設置9箇鉀肥用量水平,在雲南9箇不同生態類型的油菜產區組織3次重複的單因素隨機區組聯閤大田試驗。[結果]雲南油菜適量施用鉀肥能夠提高籽粒產量,鉀肥用量為150-180kgK2O/hm2時,油菜產量可達到3983-4151kg,比K0對照增產4.7%-9.1%,併在K165處理處齣現產量峰值;每施用K2O1kg,可增加油菜籽粒產量559kg,純利潤達到1229元/hm2,產投比達到1：1.95,鉀肥偏生產力達到31.32kg/kgK2O,鉀肥農學利用率達到3.7kg/kgK2O;施鉀可促使油菜健壯生長,具有增果實、增粒、促進籽粒充實的作用。[結論]雲南油菜鉀肥高產高效生產的適宜推薦範圍為150-180kg K2O/hm2。但綜閤攷慮產量和效益等因素,雲南省適宜K2O施用量在73.9kg/hm2左右,隴川、玉龍和臨翔產區及條件類似產區應適噹增加到100kg/hm2左右較為閤理。

[Objective] This study aimed at investigating the effects of consumption of potassium fertilizer on production and biological characteristics of rape and utilizing efficiency of potassium fertilizer.[Method] Taking 0 kg/hm2 as control,nine consumptions of potassium fertilizer were designed for the experiment using single factor randomized block design with three replications and field experiment in nine rape-producing areas with different ecological types in Yunnan Province.[Result] Appropriately applying potassium fertilizer in Yunnan Province could improve the rapeseed production,the rape production could achieve 3 983-4 151 kg when applied 150-180 kg/hm2 of K2O,which had increased by 4.7-9.1% compared with the control and attained the peak in K165 treatment.When applied 1 kg of K2O,the rapeseed production could enhance 559 kg,the net profit could reach 1 229 yuan/hm2 and the partial productivity of potassium fertilizer could attain 31.32 kg/kg K2O and 3.7 kg/kg K2O,respectively.Applying potassium fertilizer could promote the growth of rape and increase rapeseed production.[Conclusion] The recommended optimal consumptions of potassium fertilizer with high production and high efficiency for rape in Yunnan Province were ranged between 150 and 180 kg K2O/hm2.However,comprehensively considering production and efficiency factors,the consumption of potassium fertilizer in Yunnan Province was around 73.9 kg/hm2,which should be appropriately increased to around 100.0 kg/hm2 in Longchuan,Yulong,Linxiang and other producing areas with similar conditions.
