Abstract In view of the current situation of water resources shortage in China and the low effective utilization rate of agricultural irrigation water. To improve the efficiency and efficiency of agricultural irrigation water, accelerate the research and development and promotion of high-tech intelligent agricultural equipment, and reduce the proportion of agricultural input and agricultural water use. The nume-rical simulation and orthogonal model tests were combined, a four-factor and three-level orthogonal test optimization scheme was formulated, and the performance of the new micro-pipe turbine at the design flow point was calculated for 9 different schemes, and verified by physical model test. The results show that the pressure pulsation in the turbine is mainly affected by the blade passing frequency and the passing frequency of the guide vanes. Under the design flow rate, the optimized output of the turbine is 6.30 W, and the efficiency is 85.13%, which are respectively increased by 32.35% and 2.58% when compared with the preliminary design scheme. At the same time, the front-end and terminal systems of the intelligent agricultural internet of things have been developed, and a comprehensive agricultural Internet of things intelligent management system has been established that integrates self-generation, environmental monitoring, remote control, condition early warning, and growth status analysis, which greatly facilitates users. Intelligent planting and breeding technology provides a practical solution.
