摘要

Some kinds of compound soil conditioners (i.e.,Fe_1,Fe_2,Fe_3 and Fe_4) were made from materials including zero-valent iron, sulfur and calcium hydroxide according to a certain weight proportion of them. And a soil-pot trial was conducted to test effects of using those soil conditioners on vegetable yield, contents of cadmium and plumbum in vegetable, and the available contents of cadmium and plumbum in soils. Results indicated that, applying those soil conditioners could increase vegetable's yield, and decrease the contents of cadmium and plumbum in vegetables, enhance soil's pH, but reduce the available contents of Cd and Pb in soils to a certain extent. Among them, the effects of treatment "PS+CF+Fe_4" were relatively the best, it could increase vegetable's yield by 48.54%, decrease the contents of cadmium and plumbum in vegetables by 51.15%～71.31% and 10.63%～68.68%, respectively, and enhance soil's pH by 42.03%, but reduce the available contents of Cd and Pb in soils by 18.01% and 41.04%, respectively. Consequently, this kind of soil conditioner (Fe_4) has a good application prospect in the field of soils, which were suffered from the contaminated by heavy metals Cd or Pb.
