Technical Analysis and Benefit Evaluation of Intelligent Transformation of Drainage and Irrigation Systems in High-standard Farmland Construction
Abstract：Research on intelligent transformation technology of drainage and irrigation systems in high-standard farmland, aiming to address issues such as coarse traditional farmland monitoring and low irrigation efficiency. This study proposes a multi-source data fusion three-dimensional monitoring network and a LoRa/NB-IoT hybrid networking scheme. Based on an improved SWAP model and root water uptake function, a nonlinear irrigation decision-making algorithm is constructed, and a precise irrigation control system is developed. A three-dimensional water level monitoring network and fuzzy neural network drainage control technology are designed, reducing the time for waterlogging elimination to 4.2 hours. The integrated water and fertilizer management system improves total nitrogen productivity to 58.7 kg/kg through ion electrodes and multi-objective optimization. Application results show that the technology saves 23.6% water, achieves a water use efficiency of 1.82 kg/m³, and has an investment payback period of 3.8 years, providing an effective solution for water-saving and efficiency enhancement in modern agriculture.
