内蒙古东部寒区水稻田自动控制灌溉系统研究

Study on Automatic Control Irrigation System of Paddy Field in Cold Region of Eastern Inner Mongolia

水稻产业已经成为内蒙古自治区东部寒区主要产业之一,受水土资源分布不均、水资源短缺等因素影响,水稻产业发展受到限制。为提高当地灌溉管理水平和灌溉水利用效率,根据内蒙古东部寒区特点制定科学节水灌溉制度,并将自动化、信息化技术引入田间,形成水稻田自动控制灌溉系统,完成灌溉任务。结果表明,在相同气候条件和农业种植条件下,自动控制灌溉比常规灌溉的灌水量降低37.3%,水分生产率提高28.8%。水稻田自动控制灌溉技术显著减少人力资源,节水效果十分显著。未来还需要进一步开发灌溉预报模型和灌溉决策模型,提高灌溉用水决策的科学性,形成智慧灌溉系统。

Rice industry has become one of the main industries in the cold eastern region of Inner Mongolia Autonomous Region.In order to improve the local irrigation water management level and the utilization efficiency of irrigation water,a scientific water-saving irrigation system was formulated according to the characteristics of the cold region in eastern Inner Mongolia,and automation and information technology was introduced into the field to form an automatic control system for paddy fields and complete the irrigation task.The results showed that under the same climate conditions and agricultural planting conditions,the irrigation volume of automatic control irrigation decreased by 37.3%and water productivity increased by 28.8%compared with conventional irrigation.The automatic control irrigation technology of paddy field greatly reduces human resources and has remarkable effect on water saving.Further development of irrigation forecasting model and irrigation decision-making model is needed to improve the scientific nature of irrigation water decision-making and form an intelligent irrigation system.
