摘要: 通过水培实验和土培实验,研究了铜陵铜尾矿对5种豆科植物种子萌发和幼苗生长的影响.结果表明,五种豆科植物种子在尾矿浸提液中均能萌发,但萌发率比对照组低,而且浸提液对种子萌发产生一定的阻滞作用,酸化尾矿浸提液对种子萌发初期的吸胀吸水有促进作用.尾矿与土壤5种不同改良方式的基质试验也发现铜尾矿对种子萌发存在着阻滞作用.其中大豆、赤豆、赤小豆在70d内未发现死苗现象.

Abstract: Through solution culture and soil culture experiments,effects of Tongling copper mine tailings on seed germination and seeding growth of five legumes species were studied in this paper.The results showed that the seeds of five legumes species could germinate in the normal and acidified tailings extracted solution,but germination percentage was lower than that under control.It indicated that tailings extracted solution had inhibition effect on seed germination,however,acidified tailings extracted solution promoted absorbing water of the seeds in early stage.In five amelioration substrates between tailings and soils,the tailings also inhibited seed germination of the five species.No dead seedlings of Glycine max, Phaseolus angularis, P.calacaratus were found within 70 days.
