中文摘要	通过荒地和苜蓿地土壤养分、土壤胡敏酸热解特性和红外光谱特征的比较,研究了灰漠土上种植苜蓿培肥对土壤养分和土壤有机质特性的影响.结果表明,种植苜蓿可以增加土壤有机质、全N和碱解N的含量,但速效磷和速效钾含量则下降,土壤pH不变.苜蓿地胡敏酸的脂肪族侧链较多,胡敏酸较年轻,而荒地胡敏酸侧链较少,胡敏酸相对较老.苜蓿地胡敏酸的脂族性强于荒地.种植苜蓿培肥后土壤胡敏酸变得简单化和年轻化.
英文摘要	The effects of soil fertilization to gray desert soil nutrients and organic matter characteristics were studied through comparing soil nutrients,soil humic acid pyrolytic and IR characteristics between soils from uncropped and alfalfa fields.The results showed that soil organic matter,total N and available N increased,and available P and available K decreased,and soil pH didn’t change after planting alfalfa.The fatty lateral chain of humic acid from alfalfa field was much more than that from uncropped field.The fatty characteristics of soil humic acid from alfalfa field was stronger than that from uncropped field.The soil humic acid from alfalfa field was simpler and younger than that from uncropped field.
