新疆石河子棉花氮肥梯度试验区厘米级无人机多光谱影像（2018年）

2018年我们和新疆农垦科学院棉花研究所的相关研究人员合作，在新疆石河子市布设了棉花梯度试验，以获取不同氮素营养条件下的棉花植株，从而研究氮素对棉花生长的影响。在棉花田间管理的关键期盛蕾期，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，可为棉花长势监测、种植行识别、杂草监测、断垄监测等研究提供数据支撑。

In 2018, we collaborated with researchers from the Cotton Research Institute of the Xinjiang Academy of Agricultural Reclamation Sciences to conduct a cotton gradient experiment in Shihezi City, Xinjiang, to collect cotton plants under different nitrogen nutrition conditions for studying the effects of nitrogen on cotton growth. During the peak squaring stage, a critical period for cotton field management, we acquired multispectral imagery using a quadrotor unmanned aerial vehicle (UAV), and performed processing including image stitching and geometric correction to generate the UAV image dataset of the study area, with a centimeter-level spatial resolution, which can provide data support for research on cotton growth monitoring, crop row identification, weed monitoring, missing row monitoring and other related studies.
