摘　　要：选择天津市蓟县、西青和大港的荒地土壤和耐盐碱的4种野生植物(猪毛菜、草木樨、艾蒿和补血草)进行盆栽试验。植株生长5个月后,测定土壤的各项理化指标。结果显示:4种植物均大大降低土壤总盐量,猪毛菜可以不同程度地降低土壤中CO23-、SO24-和有效磷;补血草对降低土壤SO24-和水溶性钙较有效;草木樨和艾蒿可以明显增加土壤有效氮含量。综合分析表明,这4种野生耐盐植物对改良盐碱地土壤效果明显。In order to study the effects of salt and alkali soils improvement with plants, in the pot test, four kinds of wild plants （Salsola collina P. ,Melilotus suaveolens L. , Artemisia argyi L. ,Limonium bicolor K. ）were cultivated in salt and alkali softs selected from the wastelands of Dagong district, Jixian county and Xiqing of Tianjin city. After growing five months, tested several kinds of Soil physiologicai index. The results showed that： four cultivation of the soil after planting, EC of three waste lands decreased significantly. S. coUina can dropped the content of CO3^2- ,SO4^2- and availabili- ty P in varying degrees, and L. bicolor can make content of SO4^2- and Ca2＋ in soil decreased efficiently, M. suaveolens and A. argyi can make content of availability N in soil increased effectively. Comprehensively analysis showed that it was efficient to use four kinds of wild plants to improve salt and alkali soils.
