摘要
通过玉米“3414”试验,以N、P、K为试验因子,以玉米产量为目标函数,确定忻府区旱地最佳氮、磷、钾配比。试验结果是:最佳施肥纯量为:N是138.15kg/hm2,P2O5是100.65kg/hm2,K2O是145.35kg/hm2,最佳施肥量对应的产量是9694.35kg/hm2。
In this paper, based on the experiment on corn “3414”, with nitrogen, phosphorus and potassium as the experimental factors, and with the yield of maize as objective function, we determined the optimal ratio of nitrogen, phosphorus and potassium, in the dry land of Xinfu district. The result shows that the optimal fertilization amount of nitrogen was 138.15kg/hm2, P2O5 was 100.65kg/hm2 and K2O was 145.35kg/hm2, and the yield accordingly was 9694.35kg/hm2.
