摘　　要：水肥一体化是将灌溉与施肥融为一体的一种节水农业技术,借助管道灌溉系统,将由固体肥料或液体肥料配兑而成的肥液适时、适量地输入到农作物根部土壤,保证农作物对水分和养分的需求。水肥一体化技术的实现对提高水、肥利用效率、减少环境污染具有重要的意义。针对水肥灌溉一体化技术控制实施过程中具有的非线性和不确定性,结合PLC控制系统稳定、可靠的特点,将模糊控制技术应用到水肥一体化控制设备,提高水肥一体化灌溉施肥机的水肥利用效率,实现水肥一体化自动精准灌溉施肥。仿真结果表明精准灌溉施肥模糊控制技术的应用达到了水肥一体化设备对高效施肥的要求,实现水肥的同步管理和高效利用。The integration of water and fertilizer is a kind of agricultural water-saving irrigation and fertilization technology integration, with the help of pipe irrigation system, by solid fertilizer or liquid fertilizer blending into liquid fertilizer timely and appropriate input to ensure the demand of crop root soil, water and nutrient of crops. The integration of water and fertilizer technology is of great significance to improving the efficiency of water and fertilizer utilization and reducing environmental pollution. Based on the nonlinear and irrigation control technology with integration of the implementation process and the uncertainty, combined with the characteristics of PLC control system is stable and reliable, the fuzzy control technique is applied to integrate water and fertilizer control equipment, improve the integration of water and fertilizer irrigation and fertilizing machine utilizing efficiency, realize the integration of water and fertilizer automatic precise irrigation fertilization. The simulation results show that the application of fuzzy control technology in precision irrigation and fertilization achieves the requirement of high efficiency fertilization by water and fertilizer integration equipment, and realizes synchronous management and efficient utilization of water and fertilizer.
