针对太湖流域稻麦农田土壤磷库出现富集，从而磷素流失加速导致太湖地区水体环境污染负荷加重的事实，综述了近几十年来太湖流域稻麦轮作农田因长期施用磷肥导致土壤磷库盈余的现状以及环境风险。从节约磷资源和保护水环境的角度，提出了既能满足作物磷素营养需求，又不造成农田土壤磷素过量积累的科学施磷方案建议。

There are increasing concerns over water eutrophification in the Taihu Lake Watershed. This paper reviewed phosphorus accumu-lation from long-term fertilization and environmental risks in rice/wheat rotation farmland in this region. An application plan of phosphorus fertilizer was thus proposed that meets crop growth without causing soil phosphorus excess accumulation.
