| 摘 要： | 为探讨肥料增效剂和植物篱对大豆-萝卜间作体系氮磷淋失的影响,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。

Effects of the fertilizer synergist and hedgerows on nitrogen and phosphorus loss in soybean-radish intercropping system |

| Abstract: | In order to better understand the influence of fertilizer synergist and hedgerows on 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, "fertilizer reduction by 40%+ hedgerow dilution +200 times fertilizer synergist" treatment 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. |
