摘要：

通过有代表性的16种中国土壤的外源铜的西红柿毒害试验,发现淋洗(使用模拟的人工雨水滤洗定量的土壤样品)可以显著提高有机碳和盐分含量较高的土壤的毒性阈值。土壤pH是影响西红柿铜毒性阈值最重要的因子。基于土壤pH和有机碳含量的两因子回归方程能够很好地预测淋洗和非淋洗土壤上铜对西红柿生物量50%抑制的毒性阈值(EC50),且相关性均达到了80%以上。当考虑到黏粒含量或阳离子交换量对EC50的影响时,对于非淋洗和淋洗土壤来说,回归方程的决定系数R2分别提高到了0.862和0.891。本试验结果证明了利用土壤性状(土壤pH,有机碳含量以及黏粒含量或阳离子交换量)可以较好地预测土壤中外源铜对西红柿生长的毒性阈值。
