Core Viewpoint - The article emphasizes the importance of water management in agriculture, highlighting advancements in irrigation systems across various regions in China to ensure food security and enhance agricultural productivity [1][4]. Group 1: Water Management and Irrigation Systems - The total area for spring irrigation in China this year is approximately 43 million acres, with summer irrigation being carried out in an orderly manner [1]. - The irrigated area of arable land in China has exceeded 108 million acres, with a gradually improving irrigation and drainage engineering system [1][4]. - The modernized irrigation systems, such as the Jiaokou Pumping Station in Shaanxi, have significantly improved water delivery efficiency, achieving a maximum flow rate of 39.5 cubic meters per second [3]. Group 2: Agricultural Productivity - The Jiaokou irrigation area has cumulatively diverted 11.8 billion cubic meters of water, resulting in an increase of 15 billion kilograms of grain production [4]. - In Henan, the average yield of summer grain is reported at 1,490 pounds per acre, with irrigation practices improving water efficiency [7]. - The investment of 658 million yuan in the People's Victory Canal irrigation area is expected to reduce water usage from 90 cubic meters to 70 cubic meters per acre while increasing grain yield from 595 kilograms to over 656 kilograms per acre [8]. Group 3: Technological Advancements - The introduction of digital technologies in irrigation management, such as real-time monitoring and automated control systems, has enhanced water management efficiency in the Anhui province [9][10]. - The digital twin technology is being promoted to improve irrigation supply efficiency and effectiveness, with ongoing trials in 49 pilot areas [11][12].

Group 1 - The article discusses the drought situation in China, highlighting measures taken in various summer grain-producing regions to mitigate the impact of drought [1][2][3] - Jiangsu province has implemented advanced irrigation techniques, including automated monitoring systems and smart irrigation, which have significantly improved water efficiency and crop yield [1][3] - In Jiangsu, a total of 13.1 billion cubic meters of water has been diverted this year, which is double the amount compared to the same period in the last five years [1] Group 2 - In Gansu province, artificial rainmaking operations have been conducted extensively, resulting in some areas receiving over 10 millimeters of rainfall, which has allowed farmers to begin planting crops [2][4] - Efforts to enhance water efficiency include modernizing irrigation channels and maintaining water supply infrastructure, which has improved water delivery capacity by 40% in certain areas [3][5] - The Central Meteorological Observatory forecasts that the drought conditions may persist, emphasizing the need for ongoing monitoring and potential artificial rainmaking to alleviate drought impacts during the summer harvest [5]

Core Points - The spring irrigation work in the province has officially commenced, with the opening of the dam at the Erfang Canal, marking a significant step in agricultural water management [1] - The provincial water resources department has organized a comprehensive irrigation supply guarantee meeting to ensure accountability and effective water management strategies [1] Group 1 - The effective irrigated area in the province is nearly 26.1 million acres, including 8.91 million acres of rice, 1.97 million acres of facility agriculture, and 15.21 million acres of irrigated land [1] - A "100-day repair campaign" has been initiated to restore seven irrigation facilities damaged last year, ensuring all repairs are completed before the spring irrigation [1] - Over 2,500 pump stations have been inspected and maintained, with timely repairs on water gates and dredging of irrigation channels to ensure efficient water delivery [1] Group 2 - As of May 1, the total water storage in 37 large reservoirs reached 15.7 billion cubic meters, which is 3.89 billion cubic meters more than the average for the same period [2] - The total water storage in 76 medium-sized reservoirs was 984 million cubic meters, exceeding the average by 223 million cubic meters [2] - By May 8, a total of 5.68 million acres of farmland had been irrigated, utilizing 225 million cubic meters of water [2] - A dynamic monitoring system for soil moisture, water conditions, and agricultural needs has been launched to ensure precise water management during the peak irrigation period [2]
