摘　　要：通过"3414"回归最优设计原理设置的青稞肥效试验结果,获得肥料效应函数方程,由此数学模型得出理论氮、磷、钾最佳施肥量,分析出本试验区的最佳施肥量为N:150.45kghm-2,P2O5:105.6kghm-2,K2O:126kghm-2,此时产量可达5328.75kghm-2。Based on optimal regression design pricinple, 3414 Fertilizer experiments on highland barley were carried out, the fertilizer effect function equation were obtained, from the math model optimum fertilizer amount of N, P and K in theory were got, that is N： 150. 45Kgha^-1, P2O5 ： 105. 6kg ha^-1, K2O 126kg ha^-1, yield could reach 5328.75kg ha^-1.
