AI Technical Summary
In existing technologies, the area ratio of field ditches within irrigation and drainage units fails to effectively combine water quantity and quality coupling, resulting in severe nitrogen and phosphorus loss from paddy fields and failing to fully utilize the ecological purification function of ditches.
By acquiring data on paddy fields, ridges, and ditches, water volume and carrying capacity are calculated, and the area of ditches is adjusted to achieve a balance between hydraulic load and carrying capacity, preventing nitrogen and phosphorus loss and utilizing the natural purification capacity of ditches.
It has reduced nitrogen and phosphorus loss from paddy fields, enhanced the ecological purification function of ditches in rice-growing areas, and provided a high-standard method for ecological farmland construction.
