摘　　要：文章针对水肥耦合技术对土壤质量产生影响进行简单概括,指出膜下滴灌水肥耦合技术可以减轻土壤板结,调控土壤温度、pH值、全盐含量、微生物数量,减少硝态氮淋溶等,从而对作物根系附近的土壤水气协调造成影响。In this paper, a simple summarization of effect of water and fertilizer coupling technology on soil quality. The drip-irrigation technique can reduce the soil-caking compaction, regulate soil temperature, pH, total salt and microbial quantity, and reduce nitrate leaching, thus affecting the soil water and gas coordination near the crop roots.
