1.
The effects of rare earth on the growth of three crops (rice, rape, soybean) in three kinds of soils (red soil, yellow fluvo-aquic soil, yellow cinnamon soil) were studied by organization for economic co operation and development (OECD) method, and the EC50 (median growth concentration) values were obtained.
从半效应浓度 (EC5 0 )值看 ,在供试条件下 ,混合稀土对红壤上水稻和油菜以及黄潮土上大豆生长量的抑制作用较大 ,毒性相对也较强。
