摘　　要：在天山畜牧昌吉生物工程有限责任公司榆树沟良种繁育基地,土壤较瘠薄,盐碱较重的地段,进行了苜蓿配合施肥试验。结果表明:配合施肥可提高杂花苜蓿干草产量,过磷酸钙与硫酸钾配合施用干草产量最高为15 860.80 kg/hm2,高于对照36.81%;同时也提高了苜蓿粗蛋白含量,改善了苜蓿品质。尿素,过磷酸钙及硫酸钾配合施用时,前两茬草粗蛋白含量分别为19.12%和19.90%,高于对照的17.4%和12.8%;提高了苜蓿种植的经济效益,尿素与过磷酸钙配合施用时效果最好,净增1 826.55元/hm2。The experiment was carried out in Yushugou Seed Production Base of Thanshan Changji Biological Engineering Company,its＇ soil was poor and salinealkali content was higher. The results showed that com- bined fertilization could elevate hay yield of Medicago varia cv. Xinmu No. 1. The highest hay yield （15 860.80 kg/ hm^2 ） was gained when fertilizing Ca （H2PO4 ） z and K2 SO4, higher 36.81% than CK. Meanwhile, crude protein content and quality of hay were also improved. When fertilizing urea,Ca（H2PO4 ）2 and KzSO4, crude protein content of the first two cuts were 19.12% and 19.90% ,which were increased by 17.4% and 12.8% when compared with CK. Economic benefit was also elevated,and among which, combination of urea and Ca（H2 PO4 ）2 was the best,its＇ net benefit was 1 826.55 yuan/hm^2.
