Abstract

Through potash fertilizer experiment,it was showed that though the soil in Qinghai is full 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.
