采用盆栽试验研究Cu、Cd单独及复合污染对不同生长时期小麦根区、非根区土壤CAT酶活性的影响.结果表明,小麦抽穗期以前,Cu、Cd胁迫下根区、非根区土壤CAT酶活性呈上升趋势,酶活性最大值出现在抽穗期或成熟期;Cu、Cd单独及复合污染条件下,小麦根区土壤的CAT酶活性大于非根区.
採用盆栽試驗研究Cu、Cd單獨及複閤汙染對不同生長時期小麥根區、非根區土壤CAT酶活性的影響.結果錶明,小麥抽穗期以前,Cu、Cd脅迫下根區、非根區土壤CAT酶活性呈上升趨勢,酶活性最大值齣現在抽穗期或成熟期;Cu、Cd單獨及複閤汙染條件下,小麥根區土壤的CAT酶活性大于非根區.

Pot test was taken to study the effects of single and combined pollution by Cu and Cd on CAT activity of rhizosphere and non-rhizosphere soil in different growth stages of wheat. The results showed that the CAT activities of rhizosphere and non-rhizosphere soil showed increasing trend before heading stage of wheat, the maximum value of enzyme activity appeared in heading stage or maturity. The CAT activity of rhizosphere soil was higher than that of non-rhizosphere soil under single and combined pollution by Cu and Cd.
