Precision agriculture technologies can help reduce farmer private costs by identifying low-yielding areas, thereby minimizing foregone revenue. This study estimates the opportunity cost of such precision conservation on 29 commercial fields in Michigan, USA, using fine-scale yield maps collected between 2020 and 2024. We employ spatial regression models and Monte Carlo simulations to account for spatial heterogeneity and price variability. Results show that under a corn-soybean crop rotation, precision conservation improves profitability in 22 of 29 fields, indicating potential for adoption without government subsidies.","摘要 保护性耕作实践能带来公共环境效益，但相关的私人成本主要由农民承担。精准农业技术有助于通过识别低产区域来降低农民的私人成本，从而最大限度地减少放弃的收入。本研究利用2020年至2024年间收集的精细尺度产量图，估算了美国密歇根州29块商业农田上此类精准保护性耕作的机会成本。我们采用空间回归模型和蒙特卡洛模拟来处理空间异质性和价格波动。结果表明，在玉米-大豆轮作下，精准保护性耕作提高了29块农田中22块的盈利能力，表明无需政府补贴也具备采用潜力。",null,"Land Economics","2026-10-02T00:00:00Z","论文",10,false,80,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,14,8,1,"基于2020-2024年29块商业田块精细产量图，量化精准保护性耕作的机会成本，结论显示多数田块无需补贴即可盈利，对智慧农业落地与农业绿色政策有参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30],"智慧农业","农业遥感","精准农业","保护性耕作","产量地图",{"code":32,"slug":33,"name":34,"path":35,"parent_code":9},"A","field-crops","大田作物","\u002Ftopic\u002Ffield-crops",[],{"status":38,"locked":14,"version":39,"method":40,"evidence":41},"partial","2026-10-22.2","rules",{"candidates":42,"agricultural_evidence":45,"reason":83},[43,50,58,65,72,78],{"code":44,"score":20,"supported":45,"title":46,"abstract":47,"tags":49},"I1",true,[],[28,48],"precision agriculture",[26,28],{"code":51,"score":52,"supported":45,"title":53,"abstract":54,"tags":57},"A3",6,[],[55,56],"玉米","corn",[],{"code":59,"score":52,"supported":45,"title":60,"abstract":61,"tags":64},"A4",[],[62,63],"大豆","soybean",[],{"code":66,"score":52,"supported":45,"title":67,"abstract":68,"tags":71},"A7",[],[69,70],"轮作","crop rotation",[],{"code":73,"score":74,"supported":45,"title":75,"abstract":76,"tags":77},"H8",4,[],[29],[29],{"code":79,"score":21,"supported":14,"title":80,"abstract":81,"tags":82},"I3",[],[],[27],"一级领域明确，二级方向需要细分",[85,86],"密歇根 精准保护性耕作 机会成本","精准农业 产量地图 玉米大豆轮作","密歇根精准保护性耕作机会成本-4234",0,"10.3368\u002Fle.103.2.110525-0095r1",{"doi":89,"openalex_id":91,"authors":92,"venue":10,"cited_by_count":88,"oa_url":102,"card":103,"direction":109,"ingested_from":110},"W7215722779",[93,96,99],{"name":94,"orcid":95},"Seo Woo Lee","https:\u002F\u002Forcid.org\u002F0009-0000-4165-9520",{"name":97,"orcid":98},"Scott M.

农提〔202 6〕110 号\n\n王春雨 委员：\n\n您提出的关于 加快推广应用“北斗+智慧农业”的建议 的 提案 收悉，现答复如下：\n\n一、关于 立足政策赋能牵引，强化规范标准设计\n\n**一是强化政策引领。**省农业农村厅先后印发了《辽宁省“人工智能+农业”三年行动方案（2025-2027 年）》和《辽宁省“数据要素×现代农业”实施方案（2024—2026 年）》提出强化农业智能装备创新应用，鼓励生产主体采用北斗辅助驾驶系统、田间作业监测终端、农业设施物联网监测与控制系统等数字化工具，提升精准作业水平。同时推进大田种植精准化，推广“北斗+智慧农业”模式，开展无人农场试点。\n\n**二是完善补贴支持。**2024 年，省农业农村厅印发《关于印发辽宁省加力支持农业机械报废更新补贴工作实施细则的通知》（辽农机〔2024〕203 号），将农用北斗辅助驾驶系统纳入农机报废更新补贴范围。为进一步加大支持力度，又印发了《关于实施好 2025 年农业机械报废更新补贴政策的通知》（辽农机〔2025〕80 号），明确报废并新购置农用北斗辅助驾驶系统，在《实施细则》确定的补贴额基础上，按 50%提高报废补贴标准。有效降低了经营主体应用北斗智能装备的成本。\n\n下一步，省农业农村厅将联合有关部门持续强化政策引导，推广北斗终端农机广泛应用，鼓励服务主体采用北斗导航等数字化工具。并持续优化补贴政策，积极研究北斗智能装备和应用补贴，推动政策红利精准直达生产一线。\n\n二、关于锚定核心技术创新，加强示范案例推广\n\n**一是强化北斗产业培育。**省工信厅组织沈阳、盘锦两市成功入选工业和信息化领域首批北斗规模应用试点城市名单，指导盘锦市召开北斗规模应用试点工作部署会，推动北斗创新应用，拓展北斗应用广度和深度。截至目前，沈阳、盘锦两市在各领域共完成 1 万余台\u002F套北斗独立定位应用。\n\n**二是坚持试点先行，梯次推进示范推广。**2024 年，省农业农村厅在农业农村部指导下，率先在铁岭市昌图县启动“北斗+智慧农业”玉米试点，依托两家规模化农机合作社完成 4.3 万亩示范任务，验证了北斗技术在东北黑土区玉米种植中的增产可行性，形成了核心技术框架。2025 年，在昌图玉米试点基础上，拓展至盘锦市大洼区布局水稻试验示范，探索“北斗+智慧农业”在我省水稻主产区的技术适配模式，积累稻区精准作业经验，形成了玉米、水稻双作物技术储备。\n\n下一步，省农业农村厅将联合有关部门推动“北斗+智慧农业”玉米水稻产量品质协同提升技术集成示范，以昌图、大洼为核心引领，有力带动全省粮食产能稳中有升。\n\n三、关于构建立体发展模式，丰富应用场景设计\n\n**一是**我省高度重视智慧农业立体发展。“十四五”期间，全省建设 1 个国家数字农业区域创新分中心（东北）和 5 个国家数字农业创新应用基地，累计培育省级智慧农业应用基地 105 个，改造提升 500 家智能化标准化畜牧养殖场，创建 19 个国家级海洋牧场，助推智慧农业场景落地。\n\n**二是**省科技厅会同省农业农村厅等单位加快农业领域智能装备应用，推动农用无人机技术在大田作物生产高质量发展中发挥重要作用。围绕大田作物农用无人机精准作业，开展“天-空-地”一体化作物养分遥感诊断、植保无人机作业精准调控、植保无人机作业方法与标准等关键技术攻关，探索可复制易推广的农用无人机精准作业新模式。\n\n**三是**省数据局会同省农业农村厅，在全省范围内广泛征集现代农业等领域“数据要素×”典型应用场景。连续两年举办“数据要素×现代农业”赛事，赛题由 3 个扩大到 8 个，参赛团队由 66 支扩大到 84 支，推动以赛促学、以赛促用、以赛促建，积极营造数字化转型的良好氛围。\n\n下一步，省农业农村厅将联合有关部门，聚焦智慧农业领域，加强北斗导航技术创新和产业链协同，推进智能农机、农业机器人、无人机等高端装备研发应用，为农业产业发展提供支撑。\n\n感谢您对全省农业农村发展的关心，希望继续对“三农”工作给予支持。\n\n联 系

satellite-derived crop canopy anomalies into regional production signals is critical for agricultural monitoring. However, standard anomaly indicators assume a stable, direct coupling between greenness and production, ignoring phenological shifts, sub-seasonal cropping dynamics, and harvested acreage fluctuations. I evaluate the validation boundaries and expected conditions of a pixel-level, day-of-year (DOY)-first Leaf Area Index (LAI) Z-score anomaly indicator with a leave- year-out baseline (2003–2022) across five contrasting global breadbaskets: Australia, Indo-Gangetic Plains (IGP), North China Plain (NCP), US Corn Belt, and Ukraine. The analysis shows that DOY- first standardization reduces temporal composite timing mismatches, though coupling with regional statistics varies systematically. Retrospective validation reveals that direct canopy-yield coupling remains robust exclusively in rainfed Australia (Pearson’s r = 0.90), where yield variability dominates production variance (explaining 90% of variance) and moisture stress limits canopy development. In contrast, three interpretation boundaries are identified: (1) greening trend-sensitivity in the IGP, where detrending reduces the association to r = 0.53; (2) temporal representativeness bias in the double-cropped NCP, requiring crop-calendar windowing to recover the wheat signal (r = 0.51); and (3) area-shock-sensitivity in Ukraine (where harvested area contractions explain 78% of production variance), decoupling canopy vigor from production (r = 0.40). Furthermore, the LAI Z-score provides a more interpretable canopy-response measure than the Vegetation Condition Index (VCI) in dense canopies where NDVI saturates. These validation levels are synthesized into a prototype diagnostic decision framework to support indicator configuration in operational monitoring systems.","将卫星反演的作物冠层异常转化为区域产量信号对农业监测至关重要。然而，标准异常指标假定绿度与产量之间存在稳定、直接的耦合关系，忽略了物候偏移、次季节作物动态以及收获面积波动。我评估了一种像元级、以年积日（DOY）为首要标准化维度的叶面积指数（LAI）Z分数异常指标在五个对比鲜明的全球粮仓——澳大利亚、印度河-恒河平原（IGP）、华北平原（NCP）、美国玉米带和乌克兰——的验证边界与预期适用条件，该指标采用留一年基线（2003—2022年）。分析表明，以DOY为首要标准化维度可减少时间合成时相不匹配，但其与区域统计数据的耦合关系存在系统性差异。回顾性验证显示，冠层与产量的直接耦合仅在雨养条件下的澳大利亚保持稳健（Pearson's r = 0.90），该地区产量变异性主导产量方差（解释90%的方差），且水分胁迫限制冠层发育。相比之下，识别出三个解释边界：（1）IGP的绿度趋势敏感性，去趋势后关联性降至r = 0.53；（2）双季种植的NCP的时间代表性偏差，需按作物日历开窗以恢复小麦信号（r = 0.51）；（3）乌克兰的面积冲击敏感性（收获面积缩减解释78%的产量方差），导致冠层活力与产量解耦（r = 0.40）。此外，在NDVI饱和的密集冠层中，LAI Z分数提供了比植被条件指数（VCI）更具可解释性的冠层响应度量。这些验证层级被综合为一个原型诊断决策框架，以支持业务化监测系统中的指标配置。","Preprints.org","2026-10-19T00:00:00Z",65,{"impact":198,"substance":256,"depth":17,"authority":52,"freshness":20,"relevant":21,"comment":257},21,"预印本提出按年积日标准化的LAI异常指标，并在五大农业区验证其适用边界，方法有新意但尚未经同行评审，属细分领域进展。",[259],{"name":252,"url":249},[26,261,262,263,264],"遥感","作物监测","产量估测","叶面积指数",{"code":32,"slug":33,"name":34,"path":35,"parent_code":9},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":268},{"candidates":269,"agricultural_evidence":45,"reason":83},[270,275,279,283],{"code":139,"score":52,"supported":45,"title":271,"abstract":272,"tags":274},[],[143,273],"wheat",[],{"code":51,"score":52,"supported":45,"title":276,"abstract":277,"tags":278},[],[55,56],[],{"code":79,"score":140,"supported":14,"title":280,"abstract":281,"tags":282},[],[],[263,262,264,261],{"code":44,"score":21,"supported":14,"title":284,"abstract":285,"tags":286},[],[],[26],[288,289],"LAI Z-score 作物监测","遥感 作物产量 估测","LAIZ-score作物监测-5404","10.20944\u002Fpreprints202610.1707.v1",{"doi":291,"openalex_id":293,"authors":294,"venue":252,"cited_by_count":88,"oa_url":249,"card":298,"direction":303,"ingested_from":110},"W7222967882",[295],{"name":296,"orcid":297},"Xiaolong Song","https:\u002F\u002Forcid.org\u002F0000-0002-2106-6629",{"tldr":299,"method":300,"finding":301,"direction":109,"opportunity":302},"验证了按年积日标准化的LAI Z-score冠层指标在五大农业区的适用边界。","用2003–2022年留一年基线，在五个全球粮仓区做LAI DOY标准化与产量相","仅雨养澳大利亚冠层-产量强耦合(r=0.90)，其余区域受趋势、物候和面积冲击影响而解耦。","可发展融合物候窗口、去趋势与收获面积因子的分区自适应冠层异常指标诊断框架。","农业人工智能与决策模型","2026-10-20T23:30:40.675672Z",{"id":306,"title":307,"url":308,"summary":309,"summary_zh":310,"content":9,"source_name":311,"source_url":308,"published_at":312,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":313,"score_detail":314,"sources":317,"tags":319,"primary_topic":323,"secondary_topics":324,"classification":325,"search_phrases":373,"slug":376,"view_count":88,"doi":377,"paper":378,"created_at":434},5314,"A data‐driven image extraction and analysis pipeline for plant phenotyping in controlled environments","https:\u002F\u002Fdoi.org\u002F10.1002\u002Fppj2.70116","Abstract Advances in automation, imaging, and artificial intelligence have enabled large‐scale plant phenotyping, but image analysis remains a critical bottleneck for crop improvement and biological discovery. We developed an integrated multispectral phenotyping framework using imagery from the Texas A&M AgriLife Automated Precision Phenotyping Greenhouse and expanded plant growth and phenotyping (PGP v2) data across maize ( Zea mays L.), cotton ( Gossypium hirsutum ), rice ( Oryza sativa ), and sorghum ( Sorghum bicolor L.). The pipeline integrates pseudo‐red‐green‐blue composite image generation, plant detection and segmentation, image stitching, vegetation‐index analysis, texture analysis, morphological trait extraction, and temporal comparison of image‐derived features to quantify changes in plant structure, spectral reflectance, and texture over time. Among the evaluated segmentation approaches, segment anything model (SAM) v3 provided the highest and most consistent accuracy across diverse crop structures, although it required greater computational time than classical methods. Segment anything model for long sequences (SAM2Long)maintained plant‐instance associations across vertically stacked frames, while scale‐invariant feature transform–based stitching reconstructed plant mosaics when individual plants extended beyond a single field of view. For each plant and imaging date, the pipeline generated an 863‐dimensional feature vector spanning vegetation indices, spectral statistics, texture descriptors, and morphological traits. The framework was evaluated through two case studies: treatment‐level temporal analysis of mutagenized sorghum lines and cold‐stress phenotyping of maize using a separate imaging system. In both studies, the extracted features supported statistical and multivariate analyses of phenotypic variation and enabled separation of plants based on treatment‐ or stress‐related responses. The combined dataset and workflow provide structured, automated, and well‐documented phenotypic analysis across multiple crops, experimental settings, and imaging systems for controlled‐environment plant science and crop improvement.","摘要　自动化、成像和人工智能的进步使得大规模植物表型分析成为可能，但图像分析仍然是作物改良和生物学发现的关键瓶颈。我们利用德克萨斯农工大学农业生命科学自动化精准表型温室（Texas A&M AgriLife Automated Precision Phenotyping Greenhouse）的图像，开发了一个集成多光谱表型分析框架，并扩展了玉米（Zea mays L.）、棉花（Gossypium hirsutum）、水稻（Oryza sativa）和高粱（Sorghum bicolor L.）的植物生长与表型分析（plant growth and phenotyping，PGP v2）数据。该流程整合了伪红绿蓝合成图像生成、植物检测与分割、图像拼接、植被指数分析、纹理分析、形态性状提取以及图像衍生特征的时间比较，以量化植物结构、光谱反射率和纹理随时间的变化。在评估的分割方法中，segment anything model（SAM）v3在不同作物结构下提供了最高且最一致的准确性，尽管其所需计算时间多于经典方法。面向长序列的segment anything model（SAM2Long）在垂直堆叠帧之间维持了植物实例关联，而基于尺度不变特征变换（scale-invariant feature transform）的拼接在单株植物超出单一视野时重建了植物拼接图。对于每株植物和每个成像日期，该流程生成了一个863维特征向量，涵盖植被指数、光谱统计量、纹理描述符和形态性状。该框架通过两个案例研究进行了评估：诱变高粱品系的处理水平时间分析，以及使用独立成像系统对玉米进行的冷胁迫表型分析。在这两项研究中，提取的特征支持了表型变异的统计分析和多变量分析，并能够根据处理或胁迫相关响应区分植物。合并的数据集和工作流程为受控环境植物科学和作物改良提供了跨多种作物、实验设置和成像系统的结构化、自动化且记录完善的表型分析。","The Plant Phenome Journal","2026-10-18T00:00:00Z",81,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":315,"relevant":21,"comment":316},9,"该研究提出一套面向多作物的自动化多光谱表型分析流程，方法新颖、数据规模可观，对智慧育种与受控环境植物科学研究具有较高参考价值。",[318],{"name":311,"url":308},[26,130,320,321,322],"图像分割","表型组学","多光谱成像",{"code":32,"slug":33,"name":34,"path":35,"parent_code":9},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":326},{"candidates":327,"agricultural_evidence":45,"reason":83},[328,333,338,345,352,359,364,369],{"code":216,"score":52,"supported":45,"title":329,"abstract":330,"tags":332},[],[219,331],"rice",[],{"code":51,"score":52,"supported":45,"title":334,"abstract":335,"tags":337},[],[55,336],"maize",[],{"code":339,"score":52,"supported":45,"title":340,"abstract":341,"tags":344},"A5",[],[342,343],"高粱","sorghum",[],{"code":346,"score":52,"supported":45,"title":347,"abstract":348,"tags":351},"A6",[],[349,350],"棉花","cotton",[],{"code":353,"score":52,"supported":45,"title":354,"abstract":355,"tags":358},"B7",[],[356,357],"温室","greenhouse",[],{"code":165,"score":244,"supported":45,"title":360,"abstract":361,"tags":363},[],[362],"artificial intelligence",[130,320],{"code":79,"score":74,"supported":45,"title":365,"abstract":366,"tags":368},[],[367],"multispectral",[322],{"code":44,"score":21,"supported":14,"title":370,"abstract":371,"tags":372},[],[],[26],[374,375],"Texas A&M 自动化表型温室","玉米 高粱 多光谱表型","TexasAM自动化表型温室-5314","10.1002\u002Fppj2.70116",{"doi":377,"openalex_id":379,"authors":380,"venue":311,"cited_by_count":88,"oa_url":308,"card":429,"direction":109,"ingested_from":110},"W7222893982",[381,383,386,389,392,394,396,399,402,405,408,411,414,417,420,423,425,427],{"name":382,"orcid":9},"Fahimeh Orvati Nia",{"name":384,"orcid":385},"Joshua Peeples","https:\u002F\u002Forcid.org\u002F0000-0001-7861-7789",{"name":387,"orcid":388},"Seth C.

This study evaluates a feature-level fusion workflow that integrates Sentinel-2 optical indices and Sentinel-1 SAR backscatter for crop-type mapping in Candipuro District, Lumajang, East Java, Indonesia. Sentinel-2 surface reflectance and Sentinel-1 IW data acquired in June–July 2023 were harmonised in Google Earth Engine to a common 10 m pixel grid, so that all comparison maps were evaluated on the same spatial support. The optical component comprised NDVI, NDBI, and NDWI, whereas the radar component used the VH\u002FVV polarisation ratio. A DEM was used only to characterise the mountainous setting and to assist terrain interpretation, and was not included as a predictor in the classifier. The stacked feature image was classified using a Random Forest model trained with 101 field-survey ground control points representing eight land-cover\u002Fcrop-related classes. Accuracy was assessed using 393 stratified random validation points. The fused-image classification achieved an overall accuracy of 93% and a kappa coefficient of 0.90. The fusion workflow yielded richer thematic differentiation than the optical-only comparison scenarios, particularly for water bodies, sugarcane, and shrubland. However, class-level results reveal substantial uncertainty for corn fields and moderate confusion in built-up and water classes. Therefore, the present workflow should be interpreted as a site-specific, single-date proof of concept rather than a fully transferable operational solution. The results indicate that Sentinel-1\u002FSentinel-2 feature fusion is promising for crop-type mapping in cloud-prone mountainous landscapes, while future work should incorporate multi-temporal phenology, richer vegetation indices, SAR texture features, uncertainty mapping, and broader field sampling.","在湿润的热带山区，准确的作物类型制图面临持续云覆盖、崎岖地形和破碎的小农户地块等挑战。本研究评估了一种特征级融合工作流，该工作流整合了Sentinel-2光学指数与Sentinel-1 SAR后向散射数据，用于印度尼西亚东爪哇省卢马姜县坎迪普罗区的作物类型制图。2023年6月至7月获取的Sentinel-2地表反射率和Sentinel-1 IW数据在Google Earth Engine中统一至共同的10 m像元网格，以确保所有对比制图均在相同的空间支撑上进行评估。光学组分包括NDVI、NDBI和NDWI，雷达组分则使用VH\u002FVV极化比值。DEM仅用于表征山区环境并辅助地形解译，未作为预测变量纳入分类器。堆叠特征影像采用随机森林模型进行分类，该模型以101个野外调查地面控制点进行训练，代表八个土地覆盖\u002F作物相关类别。精度评估使用393个分层随机验证点。融合影像分类的总体精度达到93%，Kappa系数为0.90。与仅光学对比方案相比，融合工作流产生了更丰富的专题区分能力，尤其在水体、甘蔗和灌木地方面。然而，类别层面的结果揭示了玉米田存在较大不确定性，建成区和水体类别存在中等程度的混淆。因此，本工作流应被解读为特定站点的单日期概念验证，而非完全可迁移的业务化方案。结果表明，Sentinel-1\u002FSentinel-2特征融合在多云山区景观的作物类型制图中具有前景，未来工作应纳入多时相物候、更丰富的植被指数、SAR纹理特征、不确定性制图以及更广泛的野外采样。","Engineering
