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":86,"substance":87,"depth":88,"authority":89,"freshness":20,"relevant":21,"comment":90},16,22,18,14,"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。",[92],{"name":81,"url":78},[94,26,95,96,97],"智慧农业","产量预测","遥感","作物表型",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":13,"version":39,"method":40,"evidence":101},{"candidates":102,"agricultural_evidence":44},[103,108,115,121],{"code":31,"score":16,"supported":44,"title":104,"abstract":106,"tags":107},[105],"potato",[26,105],[26],{"code":109,"score":73,"supported":44,"title":110,"abstract":111,"tags":114},"H3",[],[112,113],"灌溉","irrigation",[],{"code":116,"score":73,"supported":44,"title":117,"abstract":118,"tags":120},"I3",[],[119],"multispectral",[95,97,96],{"code":122,"score":21,"supported":13,"title":123,"abstract":124,"tags":125},"I1",[],[],[94],[127,128],"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":131,"openalex_id":133,"authors":134,"venue":81,"cited_by_count":130,"oa_url":140,"card":141,"direction":147,"ingested_from":148},"W7223067378",[135,138],{"name":136,"orcid":137},"Jiangsan Zhao","https:\u002F\u002Forcid.org\u002F0000-0003-3916-7388",{"name":139,"orcid":8},"Jaroslaw S.

摄\n\n该中心副主任彭焕介绍，根结线虫是潜藏于土壤中、破坏力极强的“隐形害虫”，可侵染3000余种植物，包括粮食、蔬菜等各类农作物。作物根系被根结线虫侵染取食后，会形成大小不一的根瘤根结，严重削弱作物根系吸收水肥的能力，造成植株生长衰弱、产量锐减。这一虫害也是影响新疆农作物稳产提质的重要原因。\n\n以往防治根结线虫，主要依靠化学类药剂。而长期施用化学药剂，不仅会让根结线虫逐渐产生抗药性，造成药效减退，还会给土壤带来负担。因此农业生产迫切需要高效环保的替代防控技术。RNA干扰技术是极具潜力的绿色防控手段，它能够精准“关闭”该害虫的关键基因，只针对靶标害虫起效，不会伤害其他生物。但该技术的活性物质在土壤中极易被分解，致使这项技术长期停留在实验室阶段，难以应用到大田生产中。\n\n此次科研团队突破技术应用瓶颈，从基因层面筛选出根结线虫的关键靶标基因MEKK-3，该基因只作用于根结线虫，对其他生物安全无害。团队搭建起该活性物质的规模化生产工艺，还采用星形聚阳离子纳米材料为有效成分打造一层“保护外壳”。相当于给药剂穿上防护外衣，使其埋入土壤后不易被分解。经过改良，根结线虫对药剂有效成分摄取量提升42.3%，基因沉默效果提高1.9倍，幼虫死亡率提升24.2%。\n\n温室试验结果显示：单纯施用活性药剂45天后，作物根部根结数量可减少56.6%；将纳米载体与药剂搭配使用，对根结线虫的防治效果提升至78.4%。科研人员探明其中机理：该关键基因被抑制后，根结线虫抵御外界胁迫、维持生存的生理通路遭到破坏，最终无法正常发育，导致死亡。\n\n彭焕介绍，这套新技术打通了从害虫靶点筛选、机理解析、规模化生产到温室试验验证的完整技术链条，证实MEKK-3基因可用于防控多种根结线虫，为研发安全广谱的新型RNA生物农药铺平了道路。他表示，未来该技术落地应用后，能够减少化学农药使用，守护耕地土壤健康，助力新疆农业绿色高质量发展，也为国内土传病虫害的绿色治理提供重要技术储备。","中国农业科学院西部农业研究中心\u002F新疆日报(2026-10)",87,{"impact":202,"substance":203,"depth":88,"authority":89,"freshness":18,"relevant":21,"comment":204},24,23,"国家级科研机构攻克RNA干扰大田应用瓶颈，数据详实、技术链条完整，具备行业示范价值，值得进入每日精选。",[206],{"name":199,"url":196},[26,208,209,59,210],"RNA干扰","根结线虫","生物农药",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[213],{"code":56,"slug":214,"name":215,"path":216,"parent_code":217},"crop-protection","农药与绿色防控","\u002Ftopic\u002Finputs-equipment\u002Fcrop-protection","F",{"status":38,"locked":13,"version":39,"method":40,"evidence":219},{"candidates":220,"agricultural_evidence":44},[221,225,229,235],{"code":56,"score":89,"supported":44,"title":222,"abstract":223,"tags":224},[59],[59],[208,210,59],{"code":31,"score":20,"supported":44,"title":226,"abstract":227,"tags":228},[26],[],[26],{"code":230,"score":50,"supported":44,"title":231,"abstract":232,"tags":234},"B7",[],[233],"温室",[],{"code":236,"score":21,"supported":13,"title":237,"abstract":238,"tags":239},"H8",[],[],[59],[241,242],"中国农科院西部中心
