transition, yet sustained adoption remains a persistent challenge under single-governance models. Methods This study constructs a theoretical analysis framework based on the Stimulus-Organism-Response (SOR) theory. Utilizing the Ordered-Probit model, mediation effect model, and fuzzy-set Qualitative Comparative Analysis (fsQCA), and drawing on micro-survey data from 332 tea farmers in Fujian Province, China, this study explores the statistically associated mechanisms and pathways through which the statistical interaction and configurational patterns of the “proactive government + efficient market” are related to farmers’ sustained adoption intention of biopesticide technologies. Results The findings reveal the following: (1) The statistical interaction term of “proactive government + efficient market” shows a significantly positive associated with farmers’ sustained adoption intention of biopesticide technologies, and its estimated synergistic pattern exhibits a nonlinear gain of “1 + 1 > 2” in the regression model. (2) Perceived value statistically mediates the relationship between the statistical interaction of proactive government and efficient market and farmers’ sustained adoption intention of biopesticide technologies, accounting for 20.60% of the total association, and there are significant differences in the mediating roles of the three sub-dimensions. The mediating role of perceived social value is the strongest (33.33%), followed by perceived economic value (15.32%), while perceived ecological value does not serve as a significant mediator. (3) Neither a proactive government nor an efficient market is a necessary condition associated with farmers’ high and sustained adoption intention of biopesticide technologies. The configuration pathways associated with farmers’ high and sustained adoption intention of biopesticide technologies can be categorized into three types: the government - market synergy pathway, the government incentive pathway driven by the market, and the market guidance pathway supported by the government. Discussion It is essential not only to support the incentive role of the proactive government and improve the guiding role of the efficient market but also to construct a dual-wheel-driven synergy mechanism of “proactive government + efficient market” from a collaborative perspective and to enhance the cultivation of farmers’ perceived value, thereby supporting the sustained adoption intention of green production technologies among farmers.","引言 绿色农业生产技术的采用与农业绿色转型密切相关，但在单一治理模式下，持续采用仍然是一项长期挑战。方法 本研究基于刺激—有机体—反应（SOR）理论构建理论分析框架，运用有序Probit模型、中介效应模型和模糊集定性比较分析（fsQCA），并基于中国福建省332户茶农的微观调查数据，探讨“有为政府+有效市场”的统计交互与组态模式同农户生物农药技术持续采用意愿之间统计关联的机制与路径。结果 研究发现如下：（1）“有为政府+有效市场”的统计交互项与农户生物农药技术持续采用意愿显著正相关，其估计的协同模式在回归模型中表现出“1+1>2”的非线性增益。（2）感知价值在有为政府与有效市场的统计交互同农户生物农药技术持续采用意愿之间起统计中介作用，占总关联的20.60%，且三个子维度的中介作用存在显著差异。感知社会价值的中介作用最强（33.33%），其次是感知经济价值（15.32%），而感知生态价值未起显著中介作用。（3）有为政府和有效市场均不是农户生物农药技术高持续采用意愿的必要条件。与农户生物农药技术高持续采用意愿相关的组态路径可归纳为三种类型：政府—市场协同路径、市场驱动的政府激励路径，以及政府支持的市场引导路径。讨论 不仅要支持有为政府的激励作用、提升有效市场的引导作用，还应从协同视角构建“有为政府+有效市场”的双轮驱动协同机制，并提升培育……","Frontiers in Sustainable Food Systems","2026-10-01T00:00:00Z",78,{"impact":127,"substance":17,"depth":18,"authority":128,"freshness":48,"relevant":21,"comment":186},"基于福建332户茶农微观数据，用SOR框架与fsQCA揭示政府市场协同促进生物农药持续采纳的机制，方法扎实、结论有政策参考价值，但属区域样本研究，影响力限于细分领域。",[188],{"name":182,"url":179},[26,190,191,192,193],"生物农药","农户采纳行为","政府市场协同","茶叶种植",{"code":195,"slug":196,"name":197,"path":198,"parent_code":146},"F4","crop-protection","农药与绿色防控","\u002Ftopic\u002Finputs-equipment\u002Fcrop-protection",[],{"status":83,"locked":13,"version":33,"method":34,"evidence":201},{"candidates":202,"agricultural_evidence":42},[203,208],{"code":195,"score":20,"supported":42,"title":204,"abstract":205,"tags":207},[],[206],"农药",[190],{"code":38,"score":21,"supported":13,"title":209,"abstract":210,"tags":211},[],[],[26],[213,214],"福建 茶农 生物农药","政府市场协同 农户采纳","福建茶农生物农药-3999","10.3389\u002Ffsufs.2026.1880869",{"doi":216,"openalex_id":218,"authors":219,"venue":182,"cited_by_count":115,"oa_url":179,"card":231,"direction":235,"ingested_from":237},"W7215104563",[220,222,224,226,228],{"name":221,"orcid":8},"Xuan Zhang",{"name":223,"orcid":8},"Han Chen",{"name":225,"orcid":8},"Kaibin Zhuo",{"name":227,"orcid":8},"高彦净",{"name":229,"orcid":230},"Jinxiong Ji","https:\u002F\u002Forcid.org\u002F0009-0001-0626-9014",{"tldr":232,"method":233,"finding":234,"direction":235,"opportunity":236},"基于SOR理论，用332户福建茶农数据揭示政府与市场协同促进生物农药持续采纳的机制与路径。","SOR框架、Ordered-Probit、中介模型与fsQCA，332份茶农微观","政府与市场协同呈“1+1>2”非线性增益，感知价值中介20.60%，形成三类组态路径。","农业绿色发展与碳","可探究感知生态价值中介失效原因，并将组态路径用于不同作物与区域的绿色技术推广验证。","openalex","2026-10-02T23:30:10.121006Z",{"id":240,"title":241,"url":242,"summary":243,"summary_zh":244,"content":8,"source_name":182,"source_url":242,"published_at":245,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":246,"score_detail":247,"sources":249,"tags":251,"primary_topic":256,"secondary_topics":262,"classification":263,"search_phrases":287,"slug":290,"view_count":21,"doi":291,"paper":292,"created_at":312},3818,"Economic and environmental correlates of EU food trade: no evidence of an emission-oriented sourcing pattern","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1923165","Introduction This paper examines the environmental dimension of EU food trade with third countries over the period 2010–2021, asking whether bilateral trade patterns show evidence of an emission-oriented sourcing pattern consistent with the food neo-colonialism and ecologically unequal exchange hypotheses. Methods A theoretically consistent structural gravity model is estimated by Poisson pseudo-maximum likelihood (PPML) with a full set of exporter-by-year, importer-by-year and country-pair fixed effects, controlling for multilateral resistance and time-invariant bilateral confounders. A second-stage regression relates the estimated country-year effects to country-specific economic and environmental characteristics. Inference is based on clustered standard errors and a pair-level bootstrap. Results The first stage provides evidence of a Linder-type effect on the export side: the more alike two partners are in labour productivity, the larger the food flows between them. In the second stage, increases in a country’s own labour productivity show the strongest and most robust association with both its capacity to export food and its propensity to import it, while partner-country research and development intensity is positively associated with EU exports and negatively with EU imports. The environmental variables, by contrast, carry little explanatory power: neither partner agricultural greenhouse gas emissions per capita nor the partner’s renewable-energy share is significantly associated with either trade direction. The only significant environmental term is the dissimilarity in agricultural emissions per capita on the export side over the full period, and it enters positively — EU exports rise as partners become less alike in emissions. Because the measure is an absolute difference, it does not reveal whether partners have higher or lower emissions than the EU, and it therefore provides no support for an emission-oriented export pattern. Discussion The evidence shows no emission-oriented sourcing pattern in EU agri-food trade. Because the analysis relies on territorial rather than embodied emissions and on a single aggregate food category, it is not a direct test of the food neo-colonialism hypothesis; it does, however, indicate that economic characteristics, labour productivity and research intensity, are more robustly associated with EU agri-food trade than any of the environmental indicators considered here. For sustainable food systems, this strengthens the case for embedding consumption-based emission monitoring and sustainability conditionality in the external dimension of the European Green Deal and the Farm to Fork Strategy.","引言 本文考察了2010—2021年期间欧盟与第三国食品贸易的环境维度，旨在探究双边贸易模式是否呈现出与食品新殖民主义和生态不平等交换假说相一致的高排放导向采购模式。方法 本文采用理论一致的结构引力模型，通过泊松伪最大似然法（PPML）进行估计，并纳入完整的出口国—年份、进口国—年份及国家对固定效应，以控制多边阻力和不随时间变化的双边混杂因素。第二阶段回归将估计得到的国家—年份效应与国家特定的经济与环境特征相关联。推断基于聚类标准误和对级自助法。结果 第一阶段提供了出口侧林德型效应的证据：两个伙伴在劳动生产率上越相似，它们之间的食品流动规模越大。在第二阶段中，一国自身劳动生产率的提高与其出口食品的能力和进口食品的倾向均表现出最强且最稳健的关联，而伙伴国研发强度与欧盟出口正相关，与欧盟进口负相关。相比之下，环境变量的解释力甚微：伙伴国人均农业温室气体排放量和伙伴国可再生能源份额均与任一贸易方向无显著关联。唯一显著的环境项是全时段出口侧人均农业排放的相异性，且其系数为正——当伙伴国在排放上差异增大时，欧盟出口上升。由于该指标为绝对差值，它无法揭示伙伴国排放量高于还是低于欧盟，因此不能为高排放导向的出口模式提供支持。讨论 证据表明，欧盟农食贸易中不存在高排放导向的采购模式。由于分析依赖的是领土排放而非隐含排放，且仅使用单一综合食品类别，因此并非对食品新殖民主义假说的直接检验；然而，它确实表明，经济特征——劳动生产率和研发强度——与欧盟农食贸易的关联比本文所考察的任何环境指标都更为稳健。对于可持续食品系统而言，这强化了","2026-09-29T00:00:00Z",74,{"impact":87,"substance":17,"depth":18,"authority":128,"freshness":48,"relevant":21,"comment":248},"结构引力模型实证欧盟农食贸易与排放脱钩，方法扎实、结论有政策含义，但属学术论文、影响面偏窄，可作精选备选。",[250],{"name":182,"url":242},[26,252,253,254,255],"农业碳排放","可持续农业","欧盟农业","农产品贸易",{"code":257,"slug":258,"name":259,"path":260,"parent_code":261},"B7","protected-horticulture","设施园艺与植物工厂","\u002Ftopic\u002Fhorticulture\u002Fprotected-horticulture","B",[],{"status":83,"locked":13,"version":33,"method":34,"evidence":264},{"candidates":265,"agricultural_evidence":42},[266,272,277,282],{"code":257,"score":52,"supported":42,"title":267,"abstract":268,"tags":271},[],[269,270],"温室","greenhouse",[],{"code":38,"score":273,"supported":13,"title":274,"abstract":275,"tags":276},2,[],[],[253,26],{"code":278,"score":21,"supported":13,"title":279,"abstract":280,"tags":281},"E5",[],[],[255],{"code":283,"score":21,"supported":13,"title":284,"abstract":285,"tags":286},"H4",[],[],[252],[288,289],"欧盟 农食贸易 碳排放","农业碳排放 农产品贸易 可持续农业 欧盟农业","欧盟农食贸易碳排放-3818","10.3389\u002Ffsufs.2026.1923165",{"doi":291,"openalex_id":293,"authors":294,"venue":182,"cited_by_count":115,"oa_url":242,"card":307,"direction":235,"ingested_from":237},"W7214785359",[295,298,301,304],{"name":296,"orcid":297},"Dušan Steinhauser","https:\u002F\u002Forcid.org\u002F0000-0003-0708-9020",{"name":299,"orcid":300},"Anabela Luptáková","https:\u002F\u002Forcid.org\u002F0000-0003-1577-6891",{"name":302,"orcid":303},"Vladyslav Bato","https:\u002F\u002Forcid.org\u002F0009-0002-6131-4436",{"name":305,"orcid":306},"Elena Kašťáková","https:\u002F\u002Forcid.org\u002F0000-0003-4215-4836",{"tldr":308,"method":309,"finding":310,"direction":235,"opportunity":311},"检验2010–2021年欧盟食品贸易是否存在排放导向采购模式，结论为无证据支持。","结构引力模型PPML估计，含出口国-年、进口国-年与国家对固定效应及二阶段回归。","劳动生产率与研发强度比环境指标更能解释欧盟农食贸易，无排放导向采购证据。","可引入隐含排放与细分品类数据，检验食品新殖民主义假说并衔接碳足迹核算。","2026-09-30T23:30:07.461079Z",{"id":314,"title":315,"url":316,"summary":317,"summary_zh":318,"content":8,"source_name":182,"source_url":316,"published_at":319,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":320,"score_detail":321,"sources":324,"tags":326,"primary_topic":331,"secondary_topics":336,"classification":343,"search_phrases":396,"slug":399,"view_count":21,"doi":400,"paper":401,"created_at":423},3767,"Alfalfa-mediated phytoremediation and soil restoration for sustainable cereal and fruit crop production: a review of roles, detoxification mechanisms, nitrogen enhancement, and agroecological integration","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1963157","Soil contamination by heavy metals, petroleum hydrocarbons, and excessive agrochemical inputs, coupled with declining soil fertility, poses a major threat to sustainable cereal and fruit production and global food security. This review synthesizes evidence from peer-reviewed studies published between 2000 and 2026 to evaluate the multifunctional role of alfalfa ( Medicago sativa L.) as a biological soil engineer for phytoremediation, soil restoration, and sustainable agricultural intensification. The reviewed evidence indicates that alfalfa can contribute to the remediation of contaminated soils through phytoextraction, phytostabilization, and rhizosphere-mediated degradation of organic pollutants, while simultaneously improving soil fertility through biological nitrogen fixation (BNF). Its deep and extensive root system can enhance soil structure, aggregation, water-holding capacity, and soil organic carbon, while promoting beneficial microbial communities, nutrient cycling, and suppression of soil-borne pathogens. In cereal-based systems, these processes may reduce contaminant bioavailability, decrease dependence on synthetic fertilizers, and improve the productivity and resilience of subsequent crops. In fruit-based systems, including orchards and perennial cropping systems, alfalfa can provide additional benefits through intercropping or cover-cropping, including nitrogen inputs, improved soil moisture conservation, enhanced soil biological activity, and potential economic returns. However, the accumulation of contaminants in alfalfa biomass remains an important food- and feed-safety concern, highlighting the need for rigorous contaminant monitoring and appropriate biomass management. Emerging approaches, including targeted microbial inoculation, biochar amendments, intercropping strategies, and gene-editing technologies, may further improve remediation efficiency and agroecosystem sustainability. Overall, integrating alfalfa into cereal- and fruit-based production systems represents a promising nature-based approach for restoring degraded soils, improving soil resilience, reducing external inputs, and supporting sustainable crop production. Future research should prioritize long-term, multi-site field studies to evaluate remediation performance, contaminant mass balances, plant–microbe interactions, biomass safety, and the long-term productivity of cereal and fruit production systems.","重金属、石油烃和过量农用化学品投入造成的土壤污染，加之土壤肥力下降，对可持续的谷类与水果生产及全球粮食安全构成重大威胁。本综述综合了2000年至2026年间发表的同行评审研究证据，评估紫花苜蓿（Medicago sativa L.）作为生物土壤工程师在植物修复、土壤恢复和可持续农业集约化中的多功能作用。所综述的证据表明，紫花苜蓿可通过植物提取、植物稳定和根际介导的有机污染物降解促进污染土壤的修复，同时通过生物固氮（BNF）提高土壤肥力。其深而广泛的根系能够改善土壤结构、团聚体、持水能力和土壤有机碳，同时促进有益微生物群落、养分循环并抑制土传病原菌。在谷类作物系统中，这些过程可降低污染物的生物有效性，减少对合成肥料的依赖，并提高后茬作物的生产力和韧性。在水果系统中，包括果园和多年生种植系统，紫花苜蓿可通过间作或覆盖作物提供额外效益，包括氮输入、改善土壤保水、增强土壤生物活性以及潜在的经济回报。然而，紫花苜蓿生物量中污染物的积累仍是一个重要的食品和饲料安全问题，凸显了严格污染物监测和适当生物量管理的必要性。新兴方法，包括定向微生物接种、生物炭改良、间作策略和基因编辑技术，可能进一步提高修复效率和农业生态系统可持续性。总体而言，将紫花苜蓿纳入谷类和水果生产系统，代表了一种有前景的基于自然的途径，用于恢复退化土壤、提高土壤韧性、减少外部投入并支持可持续作物生产。未来研究应优先开展长期、多地点田间研究，以评估修复性能、污染物质量平衡、植物–微生物相互作用、生物量安全性以及谷类和水果生产系统的长期生产力。","2026-09-28T00:00:00Z",80,{"impact":18,"substance":322,"depth":18,"authority":19,"freshness":48,"relevant":21,"comment":323},21,"系统综述紫花苜蓿在污染土壤修复与农田可持续生产中的多功能作用，对绿色农业与土壤治理有参考价值，但属综述类论文，非重大突破。",[325],{"name":182,"url":316},[26,327,328,329,330],"生物固氮","紫花苜蓿","土壤修复","重金属污染",{"code":332,"slug":333,"name":334,"path":335,"parent_code":139},"A7","forage-cropping","饲草与耕作制度","\u002Ftopic\u002Ffield-crops\u002Fforage-cropping",[337],{"code":338,"slug":339,"name":340,"path":341,"parent_code":342},"H2","soil","土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil","H",{"status":83,"locked":13,"version":33,"method":34,"evidence":344},{"candidates":345,"agricultural_evidence":42},[346,354,362,369,376,380,384,390],{"code":338,"score":347,"supported":42,"title":348,"abstract":349,"tags":353},19,[339],[350,351,339,352],"土壤","根际","rhizosphere",[329,330],{"code":332,"score":18,"supported":42,"title":355,"abstract":357,"tags":361},[356],"alfalfa",[358,359,360,356],"间作","苜蓿","intercropping",[328],{"code":363,"score":364,"supported":42,"title":365,"abstract":366,"tags":368},"C4",7,[],[367,359],"饲料",[328],{"code":370,"score":52,"supported":42,"title":371,"abstract":372,"tags":375},"A8",[],[373,374],"粮食安全","food security",[],{"code":142,"score":20,"supported":42,"title":377,"abstract":378,"tags":379},[],[154],[327],{"code":38,"score":20,"supported":42,"title":381,"abstract":382,"tags":383},[],[253],[26],{"code":385,"score":162,"supported":42,"title":386,"abstract":387,"tags":389},"F2",[],[388],"基因编辑",[],{"code":391,"score":162,"supported":42,"title":392,"abstract":393,"tags":395},"H6",[],[394],"农业生态",[],[397,398],"紫花苜蓿 土壤修复 重金属","苜蓿 间作 果园 固氮","紫花苜蓿土壤修复重金属-3767","10.3389\u002Ffsufs.2026.1963157",{"doi":400,"openalex_id":402,"authors":403,"venue":182,"cited_by_count":115,"oa_url":316,"card":418,"direction":235,"ingested_from":237},"W7214674081",[404,406,408,410,412,414,416],{"name":405,"orcid":8},"E.
