The Dataset for Crop Phenology of Winter Wheat and Summer Maize in The Alluvium Plain of the Old Yellow River From 2008 to 2022

The farmland ecosystem of the Huanghuai Plain primarily cultivates winter wheat and summer maize, which have played a crucial role in ensuring national food security. To grasp the key phenological period of primary crops precisely is of great significance for estimating crop yield, improving the level of agricultural production management, and preventing agricultural meteorological disasters. The dataset integrates ecological observation data on the phenology of different crops in a two-cropping winter wheat-summer maize continuous cropping system in the alluvial plain of the Old Yellow River over the past 15 years (2008-2022). It mainly includes information on observation plots, winter wheat phenological period data, and summer maize phenological period data. It will serve as a valuable resource for regional agricultural quantitative remote sensing, crop growth model simulation, agricultural climate change research, and decision-making in agricultural production and management.
