摘要
土壤水溶性全盐是土壤理化性状的重要指标,对绿化植物的成活率有直接影响。由于城市绿化工程的需要,采集了56份土样,通过对其水溶性全盐量分析,系统研究了残渣法测定的土壤含盐量与水土比为5∶1电导率之间的关系。结果表明,水土比为5∶1的电导率与土壤全盐量之间都呈极显著正相关关系。
Water-soluble total salt in soil is an important index of soil physical and chemical properties, and has a direct impact on the survival rate of green plants. Due to the need of urban greening project, 56 soil samples were collected in this experiment. Using residue-analysis method, the relationship between soil salinity and water soil ratio of 5：1 was studied systematically by analyzing the water -soluble total salt content. The results showed that there was a very significantly positive correlation between the conductivity of water soil ratio of 5 ： 1 and the total salt content of soil.
