Research in Food Science》，影响因子7.7。“科技赋能产业的魅力，是帮企业用更聪明的方式赚钱。”王颖解释道。\n\n![Image

供图\n\n聚焦良种攻关，筑牢产业根基。 在午汲镇南白石村新品种示范基地，冀杂金苗5号、冀杂金苗6号等“金苗”系列品种长势喜人。据河北省农林科学院谷子研究所研究员张婷介绍，这两个品种利用春夏谷融合育种技术培育，兼具春谷的优良食味和夏谷的除草剂抗性。目前，冀杂金苗5号已列为邯郸市及武安市“一县一品”主导品种，冀杂金苗6号则凭借强抗逆性，成为太行山浅山丘陵区的适生主力品种。\n\n集成绿色技术，探索旱作模式。

Stage and Cultivar Influence the Interpretation of UAV-Derived NDVI for Potato Yield Assessment","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs11540-026-10161-5","Abstract Single-date UAV vegetation 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",{"impact":132,"substance":17,"depth":19,"authority":270,"freshness":177,"relevant":21,"comment":300},"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。",[302],{"name":296,"url":293},[261,49,304,305,306],"产量预测","遥感","作物表型",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":14,"version":40,"method":41,"evidence":310},{"candidates":311,"agricultural_evidence":46},[312,317,324,330],{"code":32,"score":69,"supported":46,"title":313,"abstract":315,"tags":316},[314],"potato",[49,314],[49],{"code":318,"score":45,"supported":46,"title":319,"abstract":320,"tags":323},"H3",[],[321,322],"灌溉","irrigation",[],{"code":325,"score":45,"supported":46,"title":326,"abstract":327,"tags":329},"I3",[],[328],"multispectral",[304,306,305],{"code":281,"score":21,"supported":14,"title":331,"abstract":332,"tags":333},[],[],[261],[335,336],"UAV NDVI 马铃薯 产量","马铃薯 品种 生育期 遥感","UAVNDVI马铃薯产量-5561","10.1007\u002Fs11540-026-10161-5",{"doi":338,"openalex_id":340,"authors":341,"venue":296,"cited_by_count":120,"oa_url":347,"card":348,"direction":354,"ingested_from":355},"W7223067378",[342,345],{"name":343,"orcid":344},"Jiangsan Zhao","https:\u002F\u002Forcid.org\u002F0000-0003-3916-7388",{"name":346,"orcid":8},"Jaroslaw S.
