摘要： 石灰炉渣废弃地中Pb、Cu、Zn、Cd重金属有效态含量均高于临近对照土壤，其炉渣淋出液对绿豆、蚕豆、玉米3种植物种子发芽率无影响，但均抑制其发芽势和下胚轴伸长，根长抑制率达30%~50%以上，对敏感种子黄豆的发芽率、发芽势（4d）影响明显，摸拟盆栽一个月苗期，4种植物试验组在总叶面积、株高、生物量方面均低于对照组；生理生化测定，4种植物其体内抗逆性保护物质脯氨酸(PRO)和膜过氧化产物丙二醛(MDA)含量试验组均高于对照组。试验表明：重金属是石灰炉渣废弃地植物定居、生长、繁殖的主要协迫因子之一。

Abstract: All the contents of Extractable heavy metal like Pb, Cu, Zn and Cd in limestone slagged wasteland are higher than those in contrapositive soil nearby. The slag filtrate has no effect on seed germination rate of Mung beans, Broad beans and Corns but restrains their germination vigor and protraction of hypocotyls with root restraint rate exceeding 30-50%; While it has an apparent effect on germination rate and germination vigor of sensitive seeds like Beans with P=0.05. Simulate to plant the 4 different seeds in pot for a month, Test groups have a lower data in total leaf area, plant height and weight but a much higher content of protective materials like PRO and MDA in biochemical mensuration experiment compared with CK group. The experiment indicates that High content of heavy metal is one of the main restraining factor that affects the settlement, growth and reproduction of plants on limestone slagged wasteland.
