嘉兴地区水稻土磷素状况与环境效应评估

Paddy Soil Phosphorus Status and Its Environmental Effects Evaluation in Jiaxing Area

对我国高产水稻区嘉兴地区典型水稻土进行了磷素状况测定及环境效应评估⒚结果表明，流行的磷肥管理实践已造成水稻土磷素的积累；发现水稻土的树脂磷指标可以反映出与水体环境相关的土壤生物性有效磷水平⒚此外，还就高磷水稻土磷素潜在的迁移流失的可能途径进行了探讨；

The phosphorus status of the typical paddy soil and its environmental effects were studied in Jiaxing of Zhejiang Provence,the high yield rice production area in China.The results showed that the nowadays phosphorus managment practices which were popular in this area had contributed to the paddy soil phosphorus accumulation and that the paddy soil Resin P index can be used to indicate the soil alga available phosphorus level.The potential phosphorus transport loss processes in the high level phosphorus paddy soils and the necessity of further study on the paddy soil phosphorus loss mechanism and related factors were also discussed.
