微灌水肥作业自动化智能控制系统研究

针对我国农业用水利用效率不高、化肥过量施用导致环境恶化等问题，研制开发一套适合东北地区玉米微灌水肥一体化作业的自动化智能控制系统，介绍了田间信息采集、施肥决策和智能控制施肥3个模块的功能、工作原理。实际应用结果表明，该系统实现化肥减量施用10%～12%，化肥利用率提高5%～6%，对提高水肥资源利用率具有重要意义。 

Research on Automatic Intelligent Control System of Micro Irrigation Water and Fertilizer Operation

Aiming at problems of low utilization efficiency of agricultural water and environmental deterioration caused by excessive application of chemical fertilizer in China，a set of automatic intelligent control system of micro irrigation water and fertilizer integrated operation was researched and developed which was suitable for corn planting in northeast China.Function and working principle of three modules of field information collection，fertilization decision-making and intelligent fertilization control were introduced.Practical application results showed that this system reduced fertilizer application by 10%～12% and increased fertilizer utilization by 5%～6%.It was of great significance to improve utilization rate of water and fertilizer resources.
