Pot experiments were carried out to study effects of different organic materials,lime and their combinations on wheat growth and cadmium(Cd) uptake by above-ground portions of the wheat plant.Results indicated that wheat grain yield was significantly increased with an increase in amounts of pig manure added,and significantly decreased with an increase in amounts of lime,while other treatments did not cause significant differences of Cd in grain yields.The highest rate of pig manure(Z4) or lime+low rate pig ...
