Abstract

The embodiment of the invention provides a method and system for predicting the transpiration of greenhouse crops. The method comprises the steps of acquiring greenhouse environment parameters and animage of a target crop, Acquiring a target crop parameter based on the image of the target crop; Inputting the greenhouse environment parameters and the target crop parameters into a pre-trained random forest model, and outputting a predicted value of a target crop transpiration amount; Wherein the random forest model is obtained through training by using a random forest algorithm based on greenhouse environment parameter samples and target crop parameter samples. According to the embodiment of the invention, the greenhouse environment parameters are obtained in real time; meanwhile, greenhouse crop parameters are obtained in an image processing mode; Therefore, the environmental parameters and the crop parameters are used as input parameters of the random forest algorithm, the data set istrained through the random forest algorithm, prediction of the crop transpiration amount is completed, data acquisition is convenient, arrangement is simple, the environmental parameters and the cropparameters are comprehensively considered, and the transpiration amount prediction precision is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of solar greenhouse irrigation, and more specifically, to a method and system for predicting transpiration of greenhouse crops. Background technique [0002] Crop transpiration is an important physiological function of crops. Transpiration is the process of losing water from the surface of living crops in the form of water vapor to the atmosphere. It can be divided into cutin transpiration and stomatal transpiration. Among them, stomatal transpiration is the most important mode of crop transpiration. Transpiration is of great significance to crops. The pulling force generated by transpiration is the main driving force for crops to absorb water and transport water. It can accelerate the efficiency of inorganic salt transport to the upper part, reduce the temperature of crop objects, and enable leaves to perform photosynthesis under strong light. without causing burns. [0003] In the f...
