| 摘 要： | 以干旱区绿洲土为供试土壤,用芹菜(Apium graveolens)做指示植物,通过模拟盆栽试验,研究了土壤Cd、Zn、Ni复合污染对芹菜生长及重金属吸收积累的影响.结果表明:(1)低浓度的Cd、Zn、Ni重金属复合处理在一定程度上可促进芹菜根、茎叶的生长,重金属复合作用增强时,即Cd、Zn、Ni浓度增大时,毒害作用逐...

| Abstract: | The pot experiments were carried out to investigate the effects of heavy metals(Cd,Zn,and Ni) on the growth and heavy metals accumulation in celery(Apium graveolens) when grown in the arid oasis soil.The results showed that(1) Cd,Zn and Ni complex pollution stimulated growth of root and shoot of celery when in the set range of low concentration,but inhibited when concentration of Cd,Zn and Ni at a high level.(2) In the arid oasis soil,the accumulation of Cd,Zn,Ni by celery increased with the increase of Cd,... |
