| 摘 要： | 以干旱区绿洲土壤为供试土壤,采用盆栽试验研究外源Ni污染对芹菜生长的影响及在芹菜中的富集迁移。结果表明：外源Ni的添加在低质量分数下能够促进芹菜的生长,达到一定临界值后,则出现明显的毒害作用;随着土壤中Ni的添加质量分数的增加,芹菜体内的Ni含量也随之增加。统计分析表明对芹菜根部和地上部吸收累积Ni贡献最大的均为铁锰氧...

| Abstract: | Soil samples were collected from the arid oasis region and the characteristics of transfer and enrichment of Ni in soil-celery system through pot experiments were studied.The results showed that lower concentrations of Ni could promote the growth of celery,but it appeared obvious toxicity when reached a certain level.With the increase of concentrations of Ni added into the soil,the concentrations of Ni in celery roots and leaves also increased.Statistical analysis showed that Ni of Fe-Mn oxide-bound and car... |
