Abstract: In this paper, with millet ＂Datong 34＂ as the material, the effects of different fertilization ratio on yield,economic characters of millet and the soil nutrient were obtained through the ＂3414＂ test. In the current millet production, phosphorus was the main factor restricting the production in local soil. we must apply enough pure phosphorus of 8~12 kg/667m~2. After successive years of application, nitrogen in the soil had reached a certain ability to supply, so it was enough to fertilizer pure nitrogen needed for the production, pure nitrogen of 5~10 kg/667m~2 should be applied. More fertilizer will cause too strong vegetative growth to reduce production. The content of available potassium in sandy loam soil was still low, and it should be applied to pure potassium of 2 kg/667m~2.
