摘要: The effectiveness of two kinds of magnesium oxide (MgO) materials, commercial MgO (2250kgha− 1) and a material derived from MgO and magnesium silicate minerals named 'MgO-SH-A'(2250 and 4500kgha− 11), in suppression of uptake and accumulation of cadmium (Cd) into grain of winter wheat (Triticum aestivum L. cv. Ayahikari) was examined in a Cd-contaminated alluvial paddy field under annual rice–wheat rotational system. The MgO materials were mixed into the plough-layer soil only once prior to the preceding rice …
