Abstract

The invention provides a crop growth period judgment method and device, electronic equipment and a storage medium, and relates to the technical field of agricultural remote sensing. The crop growth period judgment method comprises the following steps: acquiring a crop label, canopy spectral reflectivity, canopy temperature, air temperature and canopy height; determining a canopy temperature difference based on the canopy temperature and the air temperature; and judging the growth period of the current crop based on the crop label, the canopy spectral reflectivity, the canopy temperature difference and the canopy height. According to the crop growth period determination method and device, the electronic equipment and the storage medium provided by the invention, the crop growth period is determined based on the canopy spectral reflectivity, the canopy temperature, the air temperature and the canopy height near-earth remote sensing data, and the crop growth period is rapidly and accurately determined by fully utilizing the advantage of rapid and efficient data acquisition of the existing remote sensing technology.

Description

technical field [0001] The invention relates to the technical field of agricultural remote sensing, in particular to a method, device, electronic equipment and storage medium for judging the growth period of crops. Background technique [0002] The growth period refers to the growth stage of a certain typical developmental characteristic of crops from sowing to maturity, and is an important symbol reflecting the growth and development process of crops. instructive. Based on growth period observation, the growth status and development speed of crops can be grasped. Therefore, growth period determination plays a key role in crop quality assessment, nutritional diagnosis, yield estimation, low temperature stress, water and fertilizer rationing, variety selection, and agricultural time monitoring. [0003] In traditional agriculture, the growth period is mainly judged by manual observation. The manual observation method relies on the observers to enter the field, and according...
