| 摘 要： | 通过土柱淋溶模拟实验研究不同施磷水平对磷素淋失的影响.结果表明,随着施磷量的增加,淋洗液TP、DTP浓度和累积淋失量均呈递增趋势,各时间段测定的TP、DTP浓度均与施磷量呈极显著的正相关(r值范围0.848**-0.995**),TP、DTP的累积淋失量与施P量之间亦呈极显著的正相关(r分别为0.963**和0.962**),施磷提高了各土层土壤的Olsen-P含量,说明增施磷肥是导致地下水磷污染的重要原因.

| Abstract: | An indoor simulating experiment was conducted with repacked soil columns for studying the effect of phosphate fertilizer application on phosphorus leaching in vegetable soils.Results showed that the concentration and accumulation of TP and DTP in the leachates increased with the increase of phosphate fertilizer applied.The concentration of TP and DTP at each time point had extremely significant positive correlation to the amount of phosphorus application(r range 0.848**-0.995**).The total amount of TP and DTP also had extremely significant positive correlation with the amount of phosphorus application(r=0.963**,0.962**).Phosphorus application increased the content of Olsen-P in every layers of soil.It was indicated that phosphorus applied in an excessive amount would cause the groundwater pollution. |
