摘　　要：在云南自然条件下,采用二次饱和D-最优设计,从播种量、施磷量和行距3个因素对苜蓿的产量影响做了分析。结果表明,三者对产量的重要性依次为施磷量>播种量>行距,获得苜蓿高产的最优组合为播种量22.8kg/hm2、施磷量63kg/hm2、行距36cm,苜蓿第2年孕蕾期的累计干物质产量最大为21.53t/hm2。Alfalfa,as a pasture of high quality,plays a very important role in milk producing. To investigate the effects of the amount of sowing seed （X1）, the quantity of phosphate fertilizer （X2） and row spacing （X3） on alfalfa yield, the experiment was carried out in the nature condition of Yunnan Province with the design of two times saturation design. The results showed that X2 was the most important for the yield followed by X1 and X3 and when X1, and X2 were 22.8kg/hm2 and 63kg/hm2 respectively and X3 was 36cm, the highest total dry matter yield was gained at 21.53t/hm2.
