通过对分布在我国塔里木盆地的塔里木沙拐枣(Calligonum roborovskii A.Los.)居群的土壤特征进行分析。结果表明:塔里木沙拐枣居群土壤颗粒粒级组成较粗,属于砂土组的粗砂土类型;pH值在8.09-8.88之间,呈碱性;养分和有机质含量普遍较低;不同生境塔里木沙拐枣居群土壤颗粒、土壤盐分、土壤养分之间都存在不同程度的变异;根据土壤特征(土壤粒径、土壤盐分、土壤养分),将塔里木沙拐枣生境土壤划分为两种类型。
The soil characteristics of the population of Calligonum roborovskii A.Los. Distributed in the Tarim Basin in China were analyzed. The results showed that: the jujube population was dominated by coarse grained soil, belonging to the coarse sand type of sand group. The pH values ranged from 8.09 to 8.88, and were alkaline. The contents of nutrients and organic matter were generally low. According to the soil characteristics (soil particle size, soil salinity and soil nutrient), the soil of A. jujubaensis in Tarim Desert was divided into two types .
