Research on the Application of Digital Twin Technology in Water-saving Irrigation for Hillside Orchards: Achieving Precision Management Based on UAV 3D Modeling and Intelligent Algorithms

Abstract

This paper aims to investigate the application of digital twin reality models in water-saving irrigation for hillside orchards. By constructing digital twin models of orch ards, precision and intelligent management of irrigation systems are achieved. Taking a kiwifruit orchard in the Karst mountainous region of Guizhou as the research object, this study utilizes unmanned aerial vehicles (UAVs) and 3D modeling to construct a site model of the study area. By integrating precipitation data over the past five years and the water storage patterns during the kiwifruit growth cycle, the irrigation strategies of the target orchard are analyzed. On this basis, the construction methods, application process, and effect evaluation of digital twin reality models in water-saving irrigation for hillside orchards are elaborated . Experimental results indicate that digital twin reality models can significantly enhance the precision and efficiency of orchard irrigation, effectively improving water use efficiency of fruit trees without compromising photosynthetic efficiency, thereby providing robust support for the sustainable development of hillside orchards.
