采用4种提取剂提取广西某受重金属污染的蔗田土壤中有效态Cu、Zn、Pb和Cd。结果表明：各提取剂对土壤有效态Cu、Zn、Pb和Cd的提取量顺序为HNO3＞HOAc＞CaCl2＞NaNO3；土壤重金属Cu、Zn、Pb、Cd任意两个元素的提取率间呈现极显著的相关性。
採用4種提取劑提取廣西某受重金屬汙染的蔗田土壤中有效態Cu、Zn、Pb和Cd。結果錶明：各提取劑對土壤有效態Cu、Zn、Pb和Cd的提取量順序為HNO3＞HOAc＞CaCl2＞NaNO3；土壤重金屬Cu、Zn、Pb、Cd任意兩箇元素的提取率間呈現極顯著的相關性。

Four kinds of extractants were chosen to extract the available Cu , Zn, Pb and Cd from the soil of a heavy-metal-polluted sugarcane field in Guangxi .The results showed that the sequence of four extractants according to the extraction contents of a -vailable Cu, Zn, Pb and Cd in the soil was HNO 3>HOAc>CaCl2>NaNO3.There was a very significant correlation between the ex-traction rates of any two elements among Cu , Zn, Pb and Cd.
