Biofilm biofertilizer (BFBF) can improve soil organic matter and nutrient content without compromising yield, but its effect on plant water use and grain quality under restricted irrigation remains untested. This study evaluated BFBF's effect on rice water consumption under progressively limited irrigation. Methods A 3-month pot experiment used wetland (At 314) and dryland (Bg 251) rice varieties under two fertilizer practices, chemical fertilizer (CF, 340 kg NPK ha −1 ) and BFBF (225 kg NPK ha −1 + 2.5 L BFBF ha −1 ), and three water treatments (flooded, 100% field capacity, 65% field capacity), in a three-factor factorial completely randomized design ( n = 3). Total water usage, water use efficiency (WUE), net assimilation rate (NAR), relative growth rate (RGR), yield components, macronutrients (carbohydrates, proteins, lipids), and heavy metal content were recorded; significance was assessed via three-factor ANOVA (variety × fertilizer × water) with Tukey’s HSD test ( p \u003C 0.05). Results Total water use was significantly reduced under BFBF only in the wetland variety (ca. 12% under flooded, 10% at 100% field capacity, and no reduction at 65% field capacity). Grain Cd and Pb fell by 34 and 81%, respectively, under BFBF. Carbohydrate, protein, and lipid contents, Fe and Zn concentrations, and yield components were unaffected by fertilizer practice, varying only by variety and\u002For water treatment. BFBF increased NAR and RGR by ca. 33 and 7%, respectively, across all water treatments. Overall, BFBF matched full-rate CF for yield and nutritional composition while reducing water use and heavy-metal accumulation under dryland, water-limited conditions. Conclusion Collectively, these results position BFBF as a candidate drought-resilience strategy for rice cultivation, reducing water demand and heavy-metal accumulation without compromising grain yield or quality, particularly for dryland, water-limited conditions. Multi-season field trials are needed to confirm these responses at scale.","引言 水稻（Oryza sativa L.）栽培中的持续淹水在气候变化背景下对可持续农业和粮食安全构成挑战。生物膜生物肥料（biofilm biofertilizer，BFBF）能够在不影响产量的前提下提高土壤有机质和养分含量，但其在限制灌溉条件下对植物水分利用和稻米品质的影响尚未得到验证。本研究评估了BFBF在逐步限制灌溉条件下对水稻耗水量的影响。方法 采用为期3个月的盆栽试验，选用湿地品种（At 314）和旱地品种（Bg 251），设置两种施肥方式——化肥（chemical fertilizer，CF，340 kg NPK ha⁻¹）和BFBF（225 kg NPK ha⁻¹ + 2.5 L BFBF ha⁻¹），以及三种水分处理（淹水、100%田间持水量、65%田间持水量），采用三因素析因完全随机设计（n = 3）。记录总用水量、水分利用效率（water use efficiency，WUE）、净同化速率（net assimilation rate，NAR）、相对生长速率（relative growth rate，RGR）、产量构成因素、大量营养素（碳水化合物、蛋白质、脂质）及重金属含量；通过三因素方差分析（品种 × 肥料 × 水分）结合Tukey's HSD检验评估显著性（p \u003C 0.05）。结果 仅在湿地品种中，BFBF显著降低了总用水量（淹水条件下约降低12%，100%田间持水量下约降低10%，65%田间持水量下无降低）。BFBF处理下稻米Cd和Pb分别降低34%和81%。碳水化合物、蛋白质和脂质含量、Fe和Zn浓度及产量构成因素不受施肥方式影响，仅随品种和\u002F或水分处理变化。在所有水分处理下，BFBF使NAR和RGR分别提高约33%和7%。总体而言，BFBF在产量和营养组成方面与全量化肥相当，同时在旱地、水分受限条件下减少了用水量和重金属积累。结论 综合来看，这些结果表明BFBF可作为水稻栽培中应对干旱的候选策略，在不影响籽粒产量或品质的前提下降低水分需求和重金属积累，尤其适用于旱地、水分受限条件。仍需多季田间试验以在规模化条件下验证这些响应。",null,"Frontiers in Sustainable Food Systems","2026-09-11T00:00:00Z","论文",10,false,75,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},15,21,18,13,8,1,"盆栽试验证实生物膜菌肥在限水条件下可减水降镉铅且不减产，属有数据支撑的节水抗逆新结论，但仅为单季盆栽研究，产业级影响有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"水稻","节水灌溉","抗旱育种","生物膜菌肥","重金属阻控",0,"10.3389\u002Ffsufs.2026.1819208",{"doi":33,"openalex_id":35,"authors":36,"venue":10,"cited_by_count":32,"oa_url":6,"card":51,"direction":55,"ingested_from":57},"W7212303356",[37,39,41,43,46,49],{"name":38,"orcid":9},"Chamudika Gunawardhana",{"name":40,"orcid":9},"Aravindi Epa",{"name":42,"orcid":9},"Sidath Ekanayake",{"name":44,"orcid":45},"Mahesh Premarathna","https:\u002F\u002Forcid.org\u002F0000-0002-6127-3956",{"name":47,"orcid":48},"Gamini Seneviratne","https:\u002F\u002Forcid.org\u002F0000-0003-1562-4097",{"name":50,"orcid":9},"Saman Seneweera",{"tldr":52,"method":53,"finding":54,"direction":55,"opportunity":56},"盆栽试验表明生物膜菌肥可降低水稻耗水与重金属积累，且不减产。","3个月盆栽三因素试验，2品种×2施肥×3水分，测耗水、生长、产量与品质。","菌肥使湿地稻耗水降约12%，籽粒镉铅降34%和81%，产量品质与全量化肥相当。","农业绿色发展与碳","可开展多季田间验证，并探究菌肥节水降镉的微生物机制与区域适配性。","openalex","2026-09-13T23:30:07.401817Z"]
