Grasp the water for spring irrigation to help the grain harvest -- first-line experience of spring cultivation and irrigation in the middle reaches of the Yangtze River

2023-03-01

At present, it is an important time to prepare for irrigation in spring. In the middle reaches of the Yangtze River, such as Jiangxi and Hunan, which suffered a severe drought last year, can the demand for water for spring irrigation be met this year? How can the local government seize the agricultural season, do a good job in spring irrigation, and lay a solid water conservancy foundation for the summer harvest? In recent days, reporters have interviewed this. The reservoir water storage is generally good and effective to ensure the spring irrigation water demand. Since the winter of 2022, the precipitation in China is generally low. Can the reservoir water storage in the Yangtze River basin guarantee the spring irrigation water demand? Before going to Jiangxi and other major grain provinces for research, the reporter walked into the door of the Ministry of Water Resources.

Liu Shiping, a reporter from the Xinhua News Agency, said, "In the middle reaches of the Yangtze River, which suffered from severe drought last year, there have been three strong rainfall processes since February this year. The accumulated precipitation is 80 mm, nearly 60% higher than the same period of the year. The water level of the main stream and two lakes in the middle reaches of the Yangtze River has risen significantly, and the low water level in the river has been greatly improved." Wang Zhangli, deputy director of the Department of Flood and Drought Disaster Prevention of the Ministry of Water Resources, said that the reservoir water storage in the middle reaches of the Yangtze River is generally good, It is unlikely that a large-scale drought will occur this year, but there may be insufficient irrigation water in some areas. In Wuhan, Hubei Province, Chen Guiya, deputy chief engineer of the Yangtze River Water Conservancy Commission of the Ministry of Water Resources, told reporters that the drought in the middle and lower reaches of the Yangtze River has been basically alleviated due to the early rainfall, which is conducive to the storage of water in the reservoir and the guarantee of water for spring irrigation. Chen Guiya said that as of 8:00 on February 24, the water storage capacity of reservoirs in the upper and middle and lower reaches of the Yangtze River was 26.2 billion cubic meters and 16.6 billion cubic meters respectively, which could meet the water supply along the Yangtze River, including irrigation water demand. However, the water level in the main stream of the middle reaches of the Yangtze River, Poyang Lake and Dongting Lake is still low. The local water conservancy departments have planned ahead, coordinated all kinds of water sources, formulated water supply plans, and prepared for ensuring the water supply for spring irrigation.

Liu Shiping, a reporter from Xinhua News Agency, took a photo to strengthen the construction, management and protection of irrigation areas to ensure the demand for water for spring irrigation. Large and medium-sized irrigation areas are the main battlefield of food production. It is essential to do a good job in infrastructure construction and irrigation canal maintenance of large and medium-sized irrigation areas. The reporter saw in the Ganfu Plain Irrigation District, the largest irrigation district in Jiangxi Province, that at the construction site of the Gangqian Water Control Project, the "Fourteenth Five-Year Plan" modernization transformation project in the irrigation district, hundreds of construction workers were working intensively. The inverted siphon body, which replaced the aqueduct for water conveyance and irrigation, had been connected, and many excavators and bulldozers were carrying out the earthwork and block stone backfilling operation of the inverted siphon body. "We will strive to realize the water supply of the inverted siphon project in June this year and bring the project benefits into play ahead of time," said Gong Laihong, deputy director of the Ganfu Plain Water Conservancy Project Management Bureau. After the completion of the Gangqian Water Conservancy Project, the irrigation area of farmland will be improved by 639000 mu.

Liu Shiping, a reporter from the Xinhua News Agency, shot that in order to do a good job in spring irrigation this year, the Ganfu Plain Irrigation District started the maintenance of engineering facilities and dredging of channels very early. According to Yang Fangfu, chief engineer of Ganfu Plain Water Conservancy Project Management Bureau, the irrigation area of Ganfu Plain irrigation area is 1.193 million mu,
