Crop growth monitoring with remote sensing is an important task of crop condition monitoring, which can provide real-time information for field management, and provide evidences for early yield estimation. In order to better study the suitability of different remote sensing methods for monitoring crop growth, the paper introduces the domestic and overseas operational applications of crop growth monitoring with remote sensing, and summarizes the applications of multi-spectral remote sensing data, hyper-spectral remote sensing data and microwave remote sensing data. Then, this paper makes a comment on the monitoring methods with remote sensing index and the monitoring methods in terms of combining remote sensing data and crop growth model. At last, the key research tasks in the future are pointed out, including the operational technology of remote sensing data of high spatial resolution and high spectral resolution, the technology research and development of cooperative monitoring crop growth with multi-spectral remote inversion parameter method, the technology research of ensemble forecast based on remote sensing information and crop growth model, and the research and development of operational system of crop growth monitoring on global scale.
