摘要

[目的] 研究不同施肥模式对太湖流域农田蔬菜产量及土体氮磷流失与营养累积的影响

为太湖流域农业面源污染防治和治理提供科学依据。[方法] 以太湖流域农田土体蔬菜地为研究对象

采用田间径流池法进行不同施肥模式的田间小区试验。[结果] 与常规施肥相比

优化施肥可减少地表径流氮磷流失量;有机肥的施用能有效抑制地表径流氮流失;与对照地相比

其他几种施肥处理均可使蔬菜植株氮、磷、钾素累积量增加。[结论] 优化施肥可使研究区蔬菜产量提高31%

可使作物肥料利用率提高27%。

Abstract

[Objective] The effects of different fertilization patterns on vegetable yield

loss of soil nitrogen

phosphorus and nutrition accumulation in farmlands of Taihu Lake basin were researched to provide scientific evidences for the prevention and control of agricultural non-point source pollution in Taihu Lake basin. [Methods] A field experiment was conducted in runoff pools constructed on typical vegetable land with six fertilization treatments in the Taihu Lake basin. [Results] Discharges of nitrogen and phosphorus in treatment of optimal fertilization were reduced in comparison with the one of chemical fertilization. Nitrogen

phosphorus

and potassium in all fertilization patterns were measured accumulated in vegetables as compared with the one of no fertilization. [Conclusion] Optimal fertilizer can increase vegetable yield and utilization ratio of nitrogen fertilizer by 31% and 27%

respectively.
