Hebei Gu'an: high standard farmland water saving and efficiency

"originally, earth ridges and ditches were used to irrigate the land, which was a waste of water and time, using a sprinkler and an intelligent machine well room, and equipped with a smart electric card, but now it can be done by one person." Ning Guojiang, a large grain grower in Xianggongzhuang Village, Lilangdian Township, Gu'an County, Hebei Province, pointed to the self-propelled sprinkler irrigation machine in the field and said to the reporter, "Sprinkler irrigation saves 2/3 of water per mu than flood irrigation, and it is well irrigated. The sprinkler irrigation machine can irrigate 6 mu of land in 4 hours. if you have to hire four more people, you will have to pay 100 yuan per person per day.

Ningguojiang has planted 150 mu of wheat, and the construction of high-standard farmland has brought him a lot of convenience. Not only the sprinkler irrigation machine enjoys the project subsidy of comprehensive agricultural development, but also the wheat planted is a water-saving variety introduced and popularized from the Chinese Academy of Agricultural Sciences, which only needs 2 watering during the growth period, which is less than that of the traditional varieties. After the land is leveled, large plots of land are used for cultivation, and the ridges and ditches that have been knocked out can grow wheat, and each mu of land can increase the sown area of one point of land. In the past, the yield of wheat was less than 800jin per mu, but now it can reach 1100 jin.

Gu'an is the first batch of national agricultural comprehensive development project counties, which undertakes the task of building high-standard farmland with drought and waterlogging, high and stable yield. Take the Lilangdian Township project area where Ningguojiang is located as an example, because there is no external surface water, irrigation water uses shallow groundwater. Before that, there were 209 motor wells with a depth of about 100 meters, due to insufficient depth, insufficient water output, and uneven distribution. And most farmland have unreasonable slopes to varying degrees, resulting in difficulties in irrigating land and serious waste of water resources. In addition, the content of organic matter in farmland soil is low, which affects the local grain yield.

Since 2014, the local comprehensive agricultural development has been intensified. Through land preparation, dredging in gullies and ponds, supporting road, bridge, culvert, sluice irrigation and drainage facilities, and the construction of farmland forest network, farmland infrastructure has been improved, land output rate and water resources utilization rate have been increased. Today, walking through the project area, you can see neat rows of shelterbelts, high-standard intelligent computer-controlled rooms everywhere, and straight and wide machine paths. In line with the comprehensive agricultural development, the local area has also organized and promoted practical techniques such as water-saving and efficient planting of wheat and high-efficiency cultivation models in the field.

Yin Yanjun, deputy director of the Gu'an County Agricultural Comprehensive Development Office, said that building high-standard farmland, strengthening soil improvement and farmland renovation, and promoting water-saving and efficiency-increasing technologies can effectively increase grain production capacity. So far, 20, 000 mu of high-standard farmland has been built, a number of key agricultural industrialization projects have been supported, grain production capacity has been increased by 45 million jin, and farmers' annual income has increased by more than 52 million yuan. After the improvement of medium-and low-yield fields, it has attracted many large families to transfer land, and the land rent has risen from 400 yuan per mu to more than 900 yuan per mu.
