Description

Technical Field

[0001] The present invention relates to the field of mountain water resource management and agricultural irrigation, and in particular to an irrigation area water storage control system for slope planting and a water storage dynamic control method. Background Art

[0002] The sufficient supply of water in all stages of slope crop planting directly affects the fruit yield and quality. At present, the agricultural irrigation water in mountainous areas is mainly groundwater. Excessive development of groundwater will inevitably destroy the ecological balance. Some areas collect rainwater as an irrigation source, but rainfall has a strong seasonal factor and it is difficult to meet the long-term needs of crops. In addition, most mountainous areas use flood irrigation and furrow irrigation for irrigation, which is bound to waste water resources.

[0003] The existing irrigation management systems have the following deficiencies:

[0004] (1) Unbalanced distribution of water resources: The irrigation strategy is single and the consideration of crop water demand is limited; there are situations where water storage is not timely and water transfer is unreasonable.

[0005] (2) Insufficient information richness: Data is mostly displayed in the form of numbers, charts, etc., lacking an intuitive and visual display of the equipment's operating status. It is difficult for users to quickly obtain the real-time working status of the equipment, and their intuitive perception of the operating equipment information is low;

[0006] (3) Lack of geographical scalability: Most of them are managed and controlled in a single, flat, small-scale operating environment. They lack the ability to adapt to complex terrain such as mountains and slopes, which limits the geographical scalability of the system and cannot display its operating status in combination with point information. Summary of the invention
