在晋西北砖窑沟流域设置了饱和D——最优设计的田间试验,建立了糜子施肥数学模型。通过对模型分析,探讨了糜子的肥料效应,提出了糜子不同产量的经济最佳施肥量。
A field experiment of saturated D - optimal design was set up in the brick kiln valley of northwestern Shanxi Province, and a mathematical model of the fertilization of millet was established. Through the analysis of the model, the effect of fertilizer on the millet was discussed, and the optimal economic fertilizer amount for the different yield of millet was proposed.
