摘　　要：为探讨肥料增效剂和植物篱对大豆-萝卜间作体系土壤氮磷淋失的影响,设置肥料增效剂和植物篱共7个处理,对氮磷淋失特征进行研究。结果表明,7种管理措施中,化肥减量40%+植物篱+稀释200倍罗壳素处理对TN、NO3-淋失控制效果最佳,削减率分别为56.18%、57.34%;化肥减量40%处理对NH4+、TP淋失控制效果最佳,削减率分别为48.67%、47.85%。肥料增效剂和植物篱有利于控制大豆-萝卜间作体系的氮磷淋失风险,可为保障地下水安全、实现农业清洁生产提供理论依据与技术支撑。In order to understand the influence of fertilizer synergist and hedgerows on soil nitrogen and phosphorus loss in soybean-radish intercropping system,seven treatments of fertilizer synergistic agent and hedgerow were set up to study the characteristics of nitrogen and phosphorus leaching. The results showed that among the 7 management measures,the treatment of fertilizer reduction by 40%+hedgerow +dilution 200 times fertilizer synergist had the best control effect on TN and NO3-leaching,with the reduction rate of 56.18% and 57.34% respectively. The treatment of fertilizer reduction by 40% had the best control effect on leaching loss of NH4+and TP,and the reduction rates were 48.67% and 47.85%,respectively.Fertilizer synergist and hedgerow are beneficial to control the risk of nitrogen and phosphorus leaching in soybean-radish intercropping system. It can provide theoretical basis and technical support for ensuring groundwater safety and realizing agricultural clean production.
