摘　　要：连续3年的田间试验研究了磷钾肥配合施用对油菜、玉米养分吸收和产量的影响。试验结果表明:在施用氮肥的基础上合理配施磷钾肥有利于养分的协调供应,增加了油菜、玉米植株的养分含量和吸收量,从而显著提高了油菜、玉米的产量。三季油菜、玉米平均产量均以处理P90K120最高,分别达到了1968.7kg/hm^2和4912.7kg/hm^2。The field experiment was carried out to study the effect of combination of phosphorus iertilizer and potassium fertilizer on maize, rapeseed nutrient uptake and yield for three years. The results indicated that combined application of phosphorus fertilizer and potassium fertilizer on the base of nitrogen fertilizer application were beneficial to provide the balanced nutrient, increased nutrient content and nutrient uptake in maize and rapeseed .The average yield of three seasons showed that maize and rapeseed can obtain the highest yield as the phosphorus fertilizer application was 90kg/hm^2 and the potassium fertilizer application was 120kg/hm^2.
