Core Viewpoint - The article discusses the importance of spring irrigation in ensuring agricultural productivity, highlighting various measures taken across regions to secure water resources and improve irrigation efficiency through advanced technologies like digital twin technology. Group 1: Spring Irrigation Measures - Spring irrigation is crucial for ensuring crops receive adequate water after winter, especially in regions experiencing low rainfall [2][3] - In Shaanxi, local authorities are prioritizing water supply for irrigation by managing reservoir water levels and reducing power generation water releases [2] - Hebei's irrigation system utilizes a network of canals to deliver water efficiently, creating a "10-minute irrigation circle" for farmers [2] Group 2: Water Resource Management - The Yellow River Water Resources Commission has increased the outflow from the Xiaolangdi Reservoir to meet irrigation demands, raising the flow from 750 cubic meters per second to 1300 cubic meters per second [3] - Nationally, over 9500 key reservoirs hold more than 4800 billion cubic meters of water, which is nearly 10% more than the same period last year, supporting irrigation needs [3] Group 3: Smart Irrigation Technology - The Weishan Irrigation District in Shandong has implemented a water demand prediction model that enhances irrigation efficiency by analyzing crop water needs [4][5] - The smart irrigation system allows for precise water management, resulting in an average water savings of nearly 30 cubic meters per acre and a yield increase of 20% compared to similar districts [5] Group 4: Modernization and Upgrades - The Ministry of Water Resources plans to invest over 100 billion yuan in modernizing more than 1300 irrigation districts, significantly improving irrigation capacity and water-saving practices [6] - The effective utilization of irrigation water has increased, with the irrigation area reaching 1.075 billion acres, producing 77% of the country's grain [6] Group 5: Ongoing Construction Projects - New irrigation projects are underway, such as the Jiangxiang Irrigation District in Anhui and the modernization of the Qinglongxia Irrigation District in Ningxia, which will enhance water-saving rates and increase grain production [7]
