indices are widely used to assess potato crop performance and estimate yield. However, whether their biological interpretation remains consistent across cultivars and growth stages is rarely examined. This study investigated how the relationships between UAV-derived multispectral and thermal canopy indicators and potato yield changed during crop development under contrasting irrigation in two cultivars with contrasting maturity classes (Anouk and Celandine). UAV surveys were conducted in July and August, and canopy metrics were related to final yield and tuber traits. The relationship between NDVI and yield differed markedly between cultivars and growth stages. In the early-maturing cultivar Anouk, July NDVI showed a strong positive correlation with yield ( r = 0.87, p = 0.002), whereas August NDVI was not informative. In the late-maturing cultivar Celandine, the relationship reversed from a positive correlation in July ( r = 0.56) to a strong negative correlation in August ( r = −0.80, p = 0.009), indicating that greater late-season canopy greenness was associated with lower yield. Exploratory LOOCV Random Forest models achieved the highest yield prediction accuracy using July features for Anouk ( R 2 = 0.72) and August features for Celandine ( R 2 = 0.47), while multi-temporal features provided similar predictive performance. Greater temporal declines in NDVI were associated with higher yield in both cultivars, consistent with the change in canopy greenness acting as a phenological indicator of the transition from vegetative growth to tuber bulking. These results demonstrate that the interpretation of UAV-derived vegetation indices is strongly dependent on cultivar maturity and growth stage. A single UAV acquisition may therefore provide misleading assessments of crop performance when canopy phenology is not considered. Rather than serving as fixed proxies for yield, canopy vegetation indices should be interpreted within cultivar-specific and temporal contexts when used for potato monitoring and agronomic decision-making.","摘要 单期无人机植被指数被广泛用于评估马铃薯作物表现和估算产量。然而，其生物学解释在不同品种和生育期之间是否保持一致，鲜有研究加以检验。本研究探讨了在两种成熟性类别不同的品种（Anouk和Celandine）中，不同灌溉条件下，无人机获取的多光谱与热红外冠层指标与马铃薯产量之间的关系在作物发育过程中如何变化。无人机调查于7月和8月进行，并将冠层指标与最终产量及块茎性状进行关联分析。NDVI与产量之间的关系在品种和生育期之间差异显著。在早熟品种Anouk中，7月NDVI与产量呈强正相关（r = 0.87，p = 0.002），而8月NDVI则不具有指示意义。在晚熟品种Celandine中，该关系由7月的正相关（r = 0.56）转变为8月的强负相关（r = −0.80，p = 0.009），表明后期冠层绿度越高与产量越低相关。探索性留一交叉验证（LOOCV）随机森林模型在使用Anouk的7月特征（R² = 0.72）和Celandine的8月特征（R² = 0.47）时取得了最高的产量预测精度，而多时相特征提供了相似的预测表现。两个品种中NDVI随时间下降幅度越大均与产量越高相关，这与冠层绿度变化作为从营养生长向块茎膨大转变的物候指示相一致。这些结果表明，无人机获取的植被指数的解释强烈依赖于品种成熟性和生育期。因此，在未考虑冠层物候的情况下，单次无人机采集可能对作物表现作出误导性评估。冠层植被指数不应作为产量的固定替代指标，而应在品种特异性和时间背景下加以解释，方可用于马铃薯监测和农艺决策。","Potato Research","2026-10-20T00:00:00Z","论文",79,{"impact":18,"substance":150,"depth":17,"authority":19,"freshness":114,"relevant":21,"comment":151},22,"该研究揭示UAV-NDVI与马铃薯产量的关系随品种熟期和生育阶段而反转，对智慧农业遥感监测具有实质方法学与决策参考价值。",[153],{"name":145,"url":142},[155,156,157,158,159],"智慧农业","马铃薯","产量预测","遥感","作物表型",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":163},{"candidates":164,"agricultural_evidence":45},[165,171,178,184],{"code":31,"score":166,"supported":45,"title":167,"abstract":169,"tags":170},15,[168],"potato",[156,168],[156],{"code":172,"score":20,"supported":45,"title":173,"abstract":174,"tags":177},"H3",[],[175,176],"灌溉","irrigation",[],{"code":179,"score":20,"supported":45,"title":180,"abstract":181,"tags":183},"I3",[],[182],"multispectral",[157,159,158],{"code":185,"score":21,"supported":14,"title":186,"abstract":187,"tags":188},"I1",[],[],[155],[190,191],"UAV NDVI 马铃薯 产量","马铃薯 品种 生育期 遥感","UAVNDVI马铃薯产量-5561",0,"10.1007\u002Fs11540-026-10161-5",{"doi":194,"openalex_id":196,"authors":197,"venue":145,"cited_by_count":193,"oa_url":203,"card":204,"direction":210,"ingested_from":211},"W7223067378",[198,201],{"name":199,"orcid":200},"Jiangsan Zhao","https:\u002F\u002Forcid.org\u002F0000-0003-3916-7388",{"name":202,"orcid":8},"Jaroslaw S.

日专家组对冀研谷3号百亩单产提升示范田实打实收测产，亩产 431.5 公斤，较对照田增产 13.2%，亩节本增效 269.2 元。冀研谷3号是面向冀中南夏谷区选育的高产广适夏谷中熟品种，抗烯禾啶除草剂，适配麦茬夏播两熟制茬口。","藁城是谷子传统种植区和天然富硒小米优势产区，“藁城宫米”于2020年获中国国家地理标志证明商标，是河北省名优农产品区域公用品牌。区域公用品牌的持续壮大离不开优质专用品种的稳定支撑。藁城区此前已联合谷子所筛选培育出“宫米一号”专用品种。随着产业规模扩大和市场需求多元化，藁城宫米品种谱系需持续扩充。围绕这一目标，2026年，谷子所、农机所联合石家庄市农业技术推广中心，在藁城留章建立500亩试验基地，涵盖品种展示、宽窄行穴播、条播精量播种、中耕除草、叶面肥“一喷多促”及单产提升技术。\n\n藁城地处冀中南夏谷区，小麦收获后麦茬夏播是主要种植模式，对品种提出特殊要求：生育期要适配小麦—谷子两熟制时间窗口，抗除草剂能力要解决麦茬地杂草压力大的问题，品质要满足宫米加工对籽粒外观和食味的要求。冀研谷3号正是面向这一需求选育的夏谷中熟品种，高产广适，抗烯禾啶除草剂。以冀研谷3号为载体开展品种筛选与配套技术验证，旨在为宫米品牌储备“优质+专用+适播”的后备品种资源。基地采用搭载北斗导航系统的播种机，在谷子生长中后期，实施“一喷多促”技术，通过无人机一次喷施，同步实现防病治虫、促灌浆、促籽粒增重等多重效果。冀研谷3号百亩单产提升示范田自6月21日播种以来，从种到收实施精细管理，条播精量播种配合飞防“一喷多促”，形成了“良种+良法+良机”的技术组装模式。9月29日，专家组对冀研谷3号进行实打实收测产。示范田亩产431.5公斤，较对照田增产13.2%，亩节本增效269.2元。\n\n藁城留章示范田的院地联合实践，为宫米产业集群建设提供了可复制的工作路径。品种筛选的持续深化、配套技术的集成落地、科研院所与推广机构协同机制的有效运转，正在为这一目标提供从品种到技术、从田间到品牌的系统性支撑。","河北省农林科学院
