Abstract
The heavy metal Cd seriously affects the growth and development of humans, animals and plants, at the same time, it has the characteristics of wide sources and easy delivery. In this paper, the effects of Cd contaminated soil remediation by biodegradable organic phosphonic acids HEDP, BHMTPMPA, HDTMPA and ATMP on the germination characteristics of plants were studied. The results showed that when the concentration of organic phosphonic acid HDTMPA was 4%, the germination characteristics of Zinnia elegans Jacq. are the best among the four organic phosphonic acids, the germination rate, germination potential, germination index, vigor index, root length, bud length and seedling dry weight were 62%, 25.1, 11.8, 41.3, 1.8 cm, 3.5 cm and 158 mg respectively.
