Core Viewpoint - The irrigation work in the Hetao Irrigation District has commenced, aiming to ensure a solid foundation for the spring sowing of 2026 by adhering to strict water management principles [1] Summary by Sections Irrigation Work Initiation - The opening of the North Main Canal's inlet gate marks the start of the autumn irrigation work in the Hetao Irrigation District, with an initial flow rate of 100 cubic meters per second [1] Water Management Principles - The autumn irrigation follows principles of strict total control, precise irrigation, efficient watering, and prevention of water reuse, with a total irrigation area planned to exceed 4.3 million acres and total water usage strictly controlled within 950 million cubic meters [1] Irrigation Scheduling - The irrigation management employs a refined model based on "time gradient + soil type," with early autumn irrigation scheduled from October 15 to 25 at an average quota of 140 to 150 cubic meters per acre, and late autumn irrigation from November 1 to 20 at a reduced quota of 110 to 120 cubic meters per acre [1] Special Considerations for Soil - For moderately to heavily saline-alkali land, the quota is set at 150 cubic meters per acre, balancing salt leaching, moisture retention, and water-saving needs [1] Resource Allocation and Efficiency - The irrigation district optimizes water resource allocation, prioritizing water supply for grain planting areas, and promotes models like "Party branch-led water management cooperatives" and "one shovel for irrigation" to enhance irrigation efficiency [1] Monitoring and Data Collection - A total of 120 soil moisture monitoring points and 80 soil salinity monitoring points have been established in the irrigation district to continuously collect data, aiding in the precise prediction of spring irrigation needs for 2026 and dynamic optimization of water supply plans [1]
