中文摘要：

以紫花苜蓿品种＂三得利＂为试材,采用完全随机区组试验设计,研究了氮、磷、钾不同水平组合对紫花苜蓿生产性能的影响。结果表明：施肥对紫花苜蓿生产性能均有一定的促进作用,且磷钾肥对紫花苜蓿生产性能的促进作用比氮肥对其促进作用更为显著。综合分析,在山东青岛地区紫花苜蓿的建议施肥用量为：氮肥可不施用,磷肥100～150kg/hm2,钾肥100kg/hm2。

英文摘要：

Taking the alfalfa variety ＇Sandeli＇ as material,the effect of different combinations of nitrogen, phosphorus and potassium ratios on the production performance of alfalfa were studied using a completely random design. The results showed that fertilizer had a promotion on the production performance of ＇Sandili＇, while phosphate and potassium fertilizers could significantly promote the production performance of ＇Sandili＇, and no obvious differences were observed with the application of nitrogen fertilizer. Integrated considered, no nitrogen, 100 -150 kg/hm2 phosphorus and 100 kg/hm2 potassium chloride were proposed to fertilize for the production of ＇Sandili＇ in Qingdao,Shandong province.
