A rapid monitoring and discrimination method for drought conditions in summer maize based on chlorophyll content includes: 1) Obtaining multi-spectral imagery through UAV multi-payload low-altitude remote sensing technology and measuring chlorophyll content on the ground. Additionally, calculating vegetation indices including Normalized Difference Vegetation Index (NDVI), Soil-Adjusted Vegetation Index (SAVI), and Renormalized Difference Vegetation Index (RENDVI). 2) Selecting vegetation indices and constructing regression equations with measured chlorophyll content during different growth stages. The regression equation with the highest correlation for each growth stage is chosen as the optimal model equation for that particular stage. 3) Using the optimal model equations to retrieve chlorophyll content for each period and determining thresholds for chlorophyll content across different drought levels through calibration. 4) Calculating the required vegetation indices from real-time multi-spectral imagery of the field under test, retrieving chlorophyll content, and comparing it with the established thresholds to assess the real-time drought level.

Aspects of the present disclosure relate to a control method for reporting information, a control device for reporting information, and a storage medium. The method can include recording, in response to an action of network reselection of a terminal device, reselection information of the network reselection, and determining whether the reselection information meets a preset condition, and disabling the function of the terminal device to report the reselection information if it is determined that the reselection information meets the preset condition. In this way, the power consumption caused by the reporting of the reselection information when the terminal device performs over network reselection may be prevented, thereby saving the power of the battery of the terminal device.
