Base on the results of soil salt content and survival rate of trees at two thousands sample points in ten plots in Hetao irrigation region,the relations among saline-alkali land type,soil salt content,forestation tree species and their survival rate have been anlyzed.
以内蒙古河套灌区磴口县哈腾套海苏木至乌拉特前旗苏独仑农场10个样地2 000多个样点土壤含盐量的测定和林木成活率的调查结果为依据,分析了盐碱地类型、土壤含盐量与造林树种及其成活率的关系,结果表明:河套灌区12个造林树种中,不同树种在不同盐碱地类型和土壤含盐量条件下表现不同,胡杨、枸杞、沙枣、柽柳、白刺等可在多种盐碱土类型上生长,且在较高的土壤含盐量条件下能正常生长;同一树种在不同类型的盐碱地及土壤含盐量条件下表现也不一致,成活率在各种盐碱土上一般表现为硫酸盐盐土>氯化物盐土>苏打型盐土;根据耐受土壤含盐量上限将12个树种划分为弱度耐盐、中度耐盐和强度耐盐3类,耐受盐量上限分别为<1。
