摘　　要：钾、锌肥与氮肥配施对油菜产量的盆栽试验结果表明 :钾、锌肥与氮肥的合理配施可以明显地增加油菜产量。产量的增加主要是由于三种肥料的合理配施增加了叶绿素含量 ,从而提高了油菜的光合效率 ;促进了油菜对营养元素的吸收。钾、锌肥只有在一定氮肥用量的基础上才能充分发挥其增产效果。Pot experiment of effect of combined K,N and Zn fertilizer on the yield was carried out. The results showed combined application of K,Zn,N in proper ration increased the yield of Chinese cabbage significantly.The yield increase was resulted from the increace of chlorophyll content and photosynthesis and uptake of element nutrients under optimal application of N, K, Zn. Under the condition of middle and high amount of N Fertilizer,the efficiency of K and Zn have been enhanced significantly.
