摘要: 用OECD方法,在红壤、黄潮土、黄褐土上进行了混合稀土对水稻、油菜、大豆相对出苗率影响的试验.从LC50(半致死浓度)值看,在供试条件下,稀土对水稻的毒性最小,稀土在黄褐土上对作物的毒性也较小,而稀土对黄潮土上的大豆以及红壤上的油菜的毒性则较大.

Abstract: The effects of rare earth elements(REEs) on the relative seedling ratio of three crops(rice,rape and soybean)in three soil(red soil,yellow fluvo aquic soil and yellow cinnamon soil)were studied according to OECD method,and the LC50 were obtained. Toxicity effect of REEs on rice was minimum among the crops tested. The toxicity on crops in yellow cinnamon soil was lower, whereas on soybean in yellow fluvo aquic soil and on rape in red earth were higher.
