摘　　要：马铃薯作为保证国家粮食安全的第4大粮食作物,对水肥需求量较大,水肥成为制约马铃薯可持续发展的重要因素。膜下滴灌水肥调控技术可通过合理的水肥配施达到节水、节肥和水肥高效利用目的,在实现马铃薯高产优质的同时,提高作物根层土壤酶活性,稳定土壤肥力。综述了膜下滴灌水肥调控对马铃薯产量、品质、水肥利用和根层土壤酶活性的影响,旨在为马铃薯水肥调控技术的推广和应用提供重要借鉴和参考。As the world's fourth largest food crop to ensure national food security,potato has a large demand for water and fertilizer,and water and fertilizer have become an important factor limiting sustainable development of potato.Under film-mulched drip irrigation water and fertilizer regulation technology can achieve water and fertilizer conservation,improve water and fertilizer use efficiency,through reasonable water and fertilizer application.Besides,it can also enhance soil enzyme activity in root layer of crop,and stabilize soil fertility,while achieving high potato yield and quality.A study was conducted to examine effect of film-mulched drip irrigation on potato yield,quality,water and fertilizer usage,and soil enzyme activity in root layer.Objective of this investigation was to offer valuable insights for advancement and implementation of potato water and fertilizer regulation technology.
