摘　　要：以位于山东半岛最东端的荣成市成山镇成山林场盐渍土为研究对象,开展了耐盐碱植物单叶蔓荆(Vitex trifolia)、大叶胡颓子(Elaeagnus macrphylla)、沙滩黄芩(Scutellaria strigillosa)、砂引草(Messerschmidia sibirica)、肾叶打碗花(Calystegia soldanella)、烟台补血草(Limonium franchetii)、白茅(Imperata cylindrica)和裸地(对照)处理的脱盐效果试验,通过测定土壤总盐含量,评估种植耐盐碱植物对重盐渍土盐分的影响。结果表明,不同植物的脱盐效果不同,脱盐率排序为单叶蔓荆(60.0%)>大叶胡颓子(58.4%)>烟台补血草(52.3%)>白茅(50.6%)>沙滩黄芩(49.4%)>砂引草(41.6%)>肾叶打碗花(33.4%)。7种耐盐碱植物对土壤盐度均有一定的降低作用。Taking the saline soil of Chengshan Forest Farm in Chengshan Town,Rongcheng City,the easternmost end of Shandong Peninsula as the research object,the saline-alkali-tolerant plant Vitex trifolia,Elaeagnus macrphylla,Scutellaria strigillosa,Messerschmidia sibirica,Calystegia soldanella,Limonium franchetii and Imperata cylindrica and bare land(control)treatment were used to evaluate the effects of planting saline-alkali-tolerant plants on salinity of heavy saline soil by testing the total salt content in soil.The results showed that different plants had different desalting effect,desalination rate sorting for simple V.trifolia(60.0%)>E.macrphylla(58.4%)>L.franchetii(52.3%)>I.cylindrica(50.6%)>S.strigillosa(49.4%)>M.sibirica(41.6%)>C.soldanella(33.4%).7 kinds of salt-tolerant plants has certain reducing effect on soil salinity.
