摘　　要：在瘠薄、盐碱较重的地段,进行苜蓿不同时期施肥试验,结果表明,不同时期施肥,对苜蓿产量、密度及品质均有提高的作用,夏施效果较春施好;除硫酸钾外均可提高苜蓿种植的经济效益,均可提高土壤有效养分含量。The experiment on different fertilizing period of alfalfa in the bare and salt-alkali field was carried out. The results showed： yield, density, quality of alfalfa had a distinct improvement in different fertilizing period, and effect of fertilizing in summer was better than that in spring. Expect K2SO4, others could improve economic benefit of planting alfalfa; all fertilizers could increase content of available nutrient in soil.
