摘　　要：为探讨植物种苗对水体中锌的吸收效应,采用实验室内培养方法,选择了玉米等7种作物种苗为受试品种,研究了不同植物对锌的吸收。结果表明,除棉花外,各类作物在5 d内可使水体中锌含量明显降低,黑芝麻、玉米、水稻植物幼苗的根中分别积累了高达19.8、18.8、15.9mg.g1,地上部茎叶中积累了8.2、10.1、7.1 mg.g1的锌。提出选择具有"超量积累倾向"的作物种苗进行环境水体中锌污染的植物修复。Seven crop seedlings have been selected as testing cuhivars to study the uptake effect of Zn in the water, which are cultivated in the lab. The result syowed that at 5 days the concentration of Zn decreased apparently. The accumulations of Zn in the root of sesame, corn and rice seedling are 19. 8, 18. 8 and 15.9 mg/g respectively. After the comparison and discussion of the result, crop siblings that has the ability of accumulation can be used as measures of plant rehabilitation for Zn pollution in the water.
