Taking the intelligent management of farmland water and fertilizer as the research object,this paper constructs a high-precision visual sensing water and fertilizer machine.The high-precision visual sensing technology is used to obtain the crop growth state parameter image.Based on the super-pixel image segmentation technology,the complex crop growth state image feature vector is extracted.The image is segmented by the fuzzy clustering algorithm.The growth state is predicted according to the pixel value statistical results of the target image.Combined with the environmental parameter information,the soil conductivity EC and pH prediction model in the irrigation process is constructed.The test results show that the water and fertilizer integrated machine control system can effectively predict the water and fertilizer demand of crops,improve the precision of fertilizer mixing in the irrigation process,save irrigation water consumption,improve production efficiency,and reduce labor costs.
