| 摘 要： | 文章选择12种土类共57个不同土体为研究对象,分析了土壤的基本理化性质(pH、有机质、速效磷、阳离子代换量和粘粒含量)和土壤中铜、镉全量.利用SPSS13.0统计软件预测了土壤铜、镉的植物可利用性与土壤理化性质的相关模型,发现土壤中镉的植物可利用态含量与土壤中全镉、有机质、速效磷和阳离子代换量呈正相关,与土壤pH呈负相... |

| Abstract: | Physicochemical properties including pH,organic matter(OM),available phosphorus content,CEC and clay content as well as total Cu and Cd of 57 soil samples which belonged to 12 soil types were analyzed.Statistical model for phytoavailability of Cu and Cd in different soils with soil physicochemical properties was predicted by using SPSS 13.0 software.Results indicated there was positive correlation between Cd phytoavailability and parts of physicochemical properties including total Cd,OM,available phosphorus... |
