山东禹城冬小麦水氮耦合试验区厘米级无人机多光谱影像（2019年）

中国科学院禹城农业综合试验站长期开展冬小麦水氮耦合试验，以获取不同水、氮条件下的冬小麦植株，从而研究水、氮对冬小麦生长的影响。2019年，在冬小麦田间管理的关键期拔节期，我们基于四旋翼无人机获取了无人机多光谱影像，并进行拼接、几何校正等处理，形成研究区无人机影像数据，空间分辨率达厘米级，可为冬小麦长势监测、种植行识别、杂草监测、断垄监测等研究提供数据支撑。

The Yucheng Comprehensive Agricultural Experimental Station of the Chinese Academy of Sciences has long conducted winter wheat water-nitrogen coupling experiments to collect winter wheat plant samples under different water and nitrogen conditions, so as to investigate the effects of water and nitrogen on winter wheat growth. In 2019, during the jointing stage, a critical period for winter wheat field management, we acquired multispectral imagery via a quadrotor unmanned aerial vehicle (UAV), and performed post-processing procedures including image mosaic and geometric correction to generate a UAV image dataset of the study area with centimeter-level spatial resolution. This dataset can provide data support for studies including winter wheat growth status monitoring, crop row detection, weed monitoring, broken ridge monitoring and other relevant research.
