摘要

通过室内土壤灌施间歇入渗试验，研究了灌施条件下波涌灌溉土壤间歇入渗硝态氮的运移与分布特性，分析了硝态氮分布与土壤含水量的关系，并与灌施条件下土壤连续入渗进行了对比，为进一步研究施肥条件下波涌灌溉土壤间歇入渗溶质运移规律奠定了基础。

Abstract

The nitrate nitrogen transport and distribution characteristics of intermittent infiltration under surge fertigation were researched based on indoor experimental data

the connection between nitrate nitrogen distribution and soil water content was founded

and contrasted with continuous infiltration. These research results have laid a foundation for further study of soil solute transfer theory and technology of surge irrigation fertilization.
