Legume–wheat intercropping may simultaneously improve soil quality and resource-use efficiency, but its regenerative performance under deficit irrigation remains insufficiently quantified. Methods A two-year field experiment was conducted during 2021\u002F22 and 2022\u002F23 in El-Minia Governorate, Middle Egypt, using a split-plot design with three replications. Three irrigation regimes—100%, 85%, and 70% of crop evapotranspiration (ETc)—were evaluated in combination with sole wheat and wheat intercropped with faba bean, pea, or fahl clover. Soil organic matter, available N, P, and K, soil pH, Soil Quality Index (SQI), crop yield, land equivalent ratio (LER), water equivalent ratio (WER), and change in water use (DWU) were assessed. Results All legume–wheat intercropping systems significantly improved soil organic matter and available macronutrients relative to sole wheat. Faba bean–wheat generally produced the greatest improvements in soil properties and SQI. The beneficial effects of intercropping persisted under severe deficit irrigation (70% ETc). Pea–wheat achieved the highest total LER (1.39) and WER (1.26), together with the highest wheat grain yield and a DWU of -20.48%. Conclusion Legume–wheat intercropping enhanced soil quality, land-use efficiency, and water-use efficiency under deficit irrigation. The results demonstrate that integrating legumes with wheat can provide a practical regenerative strategy for improving productivity and resilience of wheat-based systems in water-limited environments.","背景 土壤退化与水资源短缺是干旱和半干旱地区可持续谷物生产的主要限制因素。豆科作物-小麦间作可能同时改善土壤质量和资源利用效率，但其在亏缺灌溉条件下的再生性能仍缺乏充分的定量评估。方法 于2021\u002F22和2022\u002F23年度在埃及中部明亚省开展了一项为期两年的田间试验，采用裂区设计，设三次重复。评估了三种灌溉制度——分别为作物蒸散量（ETc）的100%、85%和70%——与单作小麦及小麦分别与蚕豆、豌豆或埃及三叶草间作的组合。测定了土壤有机质、速效氮、磷、钾、土壤pH、土壤质量指数（SQI）、作物产量、土地当量比（LER）、水当量比（WER）以及水分利用变化量（DWU）。结果 与单作小麦相比，所有豆科作物-小麦间作系统均显著提高了土壤有机质和速效大量元素含量。蚕豆-小麦间作通常在改善土壤性质和SQI方面效果最佳。间作的有益效应在严重亏缺灌溉（70% ETc）条件下依然持续。豌豆-小麦间作实现了最高的总LER（1.39）和WER（1.26），同时小麦籽粒产量最高，DWU为-20.48%。结论 豆科作物-小麦间作在亏缺灌溉条件下提高了土壤质量、土地利用效率和水分利用效率。结果表明，将豆科作物与小麦整合可为水资源受限环境中提高小麦种植系统的生产力和韧性提供一种实用的再生策略。",null,"Frontiers in Sustainable Food Systems","2026-09-09T00:00:00Z","论文",10,false,76,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},16,22,17,13,8,1,"两年田间试验量化了亏缺灌溉下豆科-小麦间作的土壤改良与资源利用效率提升，数据扎实、结论可靠，对干旱半干旱区小麦可持续生产有参考价值。",[25],{"name":10,"url":6},[27,28,29,30,31],"小麦","土壤健康","节水灌溉","间作套种","豆科绿肥",0,"10.3389\u002Ffsufs.2026.1923296",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":41,"direction":45,"ingested_from":47},"W7212074132",[37,39],{"name":38,"orcid":9},"S.A.H.
