中文摘要	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化态和碳酸盐结合态; 芹菜通过根系吸收的Ni主要存在于根系组织中, 根部富集能力明显大于地上部, 外源Ni的添加明显抑制了其在芹菜体内的迁移能力。
英文摘要	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 carbonate-bound form had the greatest contribution to Ni accumulation in celery overground part and root.Ni absorbed through the root mainly existed in root organization and the ability of enrichment in root was significantly greater than in overground part.The adding of Ni significantly inhibited its migratory ability in cerely.
