| Abstract: |
| 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. |
