  • 摘要: 选用观赏植物吊兰进行盆栽试验,研究了吊兰对Cd的耐性、高浓度Cd胁迫对土壤酶活性以及土壤有效态Cd含量的影响.结果表明,随着Cd浓度的不断提高,脲酶活性显著下降.过氧化氢酶和蔗糖酶活性在Cd浓度为10 mg·kg-1的时候均达到了顶峰,而土壤磷酸酶活性则在Cd浓度为50 mg·kg-1的时候最大.4种土壤酶对重金属的敏感顺序为:脲酶> 磷酸酶> 蔗糖酶>过氧化氢酶.吊兰对Cd具有很强的耐性,在1500 mg·kg-1 Cd胁迫浓度范围内,吊兰对Cd的耐性指数均大于50%.土壤有效态Cd与土壤Cd添加量和土壤酶活性呈显著相关性,可将土壤有效态Cd含量和土壤酶活性这两类指标作为镉污染土壤的评价指标.
    Abstract: The effects of cadmium exposure on Chlorophytum comosum growth, concentration of available Cd in soil and soil enzyme activities were studied. The results showed that urease activity decreased significantly with increasing Cd concentration, while the activities of catalase and invertase reached their peaks when Cd concentration was 10 mg穔g-1, and phosphatase activity reached the maximum when Cd concentration was 50 mg穔g-1. The sensitivity order of the four soil enzymes was urease>phosphatase>invertase>catalase. C. comosum had very strong tolerance for Cd. The tolerance index of C. comosum was higher than 50% at the Cd concentration up to 1500 mg穔g-1. The available Cd concentration correlates more closely to the concentration of added Cd and soil enzyme activities. Therefore, the available Cd concentration and soil enzyme activity can be used as indicators in the evaluation of cadmium-contaminated soils.

摘要: 选用观赏植物吊兰进行盆栽试验,研究了吊兰对Cd的耐性、高浓度Cd胁迫对土壤酶活性以及土壤有效态Cd含量的影响.结果表明,随着Cd浓度的不断提高,脲酶活性显著下降.过氧化氢酶和蔗糖酶活性在Cd浓度为10 mg·kg-1的时候均达到了顶峰,而土壤磷酸酶活性则在Cd浓度为50 mg·kg-1的时候最大.4种土壤酶对重金属的敏感顺序为:脲酶> 磷酸酶> 蔗糖酶>过氧化氢酶.吊兰对Cd具有很强的耐性,在1500 mg·kg-1 Cd胁迫浓度范围内,吊兰对Cd的耐性指数均大于50%.土壤有效态Cd与土壤Cd添加量和土壤酶活性呈显著相关性,可将土壤有效态Cd含量和土壤酶活性这两类指标作为镉污染土壤的评价指标.
