| 摘 要： | 研究了日光温室菜地土壤盐分、PH、重金属的垂直分布特征,并对耕层0～25cm的相关项目进行评价。结果表明,土壤盐分大致趋势是上层高于下层,而露地则与之相反;PH值上层低于下层,且耕层0～25cmPH值随种植年限的增加呈下降趋势;不同重金属在各层分布差异较大,0～25cm含量高的是汞、铬,100～150cm含量高的是铅、镉,砷在各层差异不大。

| Abstract: | The paper researches on the vertical distribution character of soil salinity,PH value and heavy metal.It shows that: the content of soil salinity of upper layer is higher than that of subsoil;the PH value of upper layer is lower than of subsoil;there is big difference of different heavy metals at different soil level,for example,the content of mercury and chromium is the highest in 0～25cm soil,the content of lead and cadmium is the highest in 100～150cm soil. |
