摘　　要：土壤镉污染是当前南方稻田面临的一大难题。从介绍镉胁迫对水稻的影响入手,总结了目前报道的土壤调节剂种类、土壤调理剂对水稻产量与镉积累的影响及机制、不同土壤调理剂的效果比较等方面的研究进展,同时就土壤调理剂的后续研究提出了研制新型土壤调节剂、降低土壤调节剂的生产成本与价格、明确土壤调节剂的适宜用量、加强土壤调理剂与农艺措施的结合、强化土壤调理剂的周年及长期应用效果研究等5个研究方向。Cadmium pollution is a major problem in paddy soils of south China.Soil conditioners are playing a positive role in reduing heavy metal absorption of crops and ensuring food security.This paper has reviewed the research progress on soil conditioner types,their effects on rice yield and cadmium accumulation,the action machanism and their efficacy differences.Accordingly,we propose to develop new types of soil conditioners,reduce the production cost and price of soil conditioners,clarify the appropriate dosage of soil conditioners,enhance the combined application of soil conditioners and agronomic measures,strengthen annual and long-term application effects of soil conditioners in the future research.
