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。
The results of pot experiment on yield of rapeseed with potassium, zinc fertilizer and nitrogen fertilizer showed that rational application of potassium, zinc fertilizer and nitrogen fertilizer could obviously increase the yield of rapeseed. The increase of yield was mainly attributed to the increase of chlorophyll content by the rational allocation of three kinds of fertilizers, which increased the photosynthetic efficiency of rapeseed and promoted the absorption of nutrient elements in rapeseed. Potassium, zinc fertilizer only in a certain amount of nitrogen on the basis of the full effect of its production.
