Irrigation decision-making method and device and electronic equipment

The invention relates to the technical field of irrigation, and provides an irrigation decision-making method and device and electronic equipment. The irrigation decision-making method comprises the following steps: acquiring a multispectral image and ground penetrating radar data of each planting block in a target planting area; extracting a vegetation index of each planting block based on the multispectral image of each planting block; inputting the vegetation index and the ground penetrating radar data of each planting block into a soil available water consumption prediction model to obtain a soil available water consumption prediction result of each planting block output by the soil available water consumption prediction model; based on the soil available water consumption prediction result of each planting block and the meteorological data of the target planting area in the future preset time period, determining the residual soil available water consumption of each planting block in the future preset tim
