摘要
钾肥试验表明,青海地区虽然钾肥含量高,但还是难以满足带状玉米的需要,如果要增加带状玉米产量还得补充钾,且钾肥的最佳施量是300kg.hm-2。
Through potash fertilizer experiment, it was showed that though the soil in Qinghai is lull of potash, but it is not enough for the growth of the belts crop field of maize. So in order to have a good harvest,it is necessary to increase application potash. And the optimum application potash volume was 300kg·ha^-1.
