Xinhuanet, Zhengzhou, March 10 (Fan Zuoyan and Dan Wenqing) After the beginning of spring, most of the winter wheat in the north is in the greening period, and "spring irrigation" is an important agricultural activity at this stage.

Recently, a precision irrigation technology developed by the Institute of Farmland Irrigation of the Chinese Academy of Agricultural Sciences entered the "trial period" and was put into use for the first time at the Chinese Academy of Agricultural Sciences base in Qiliying Town, Xinxiang County.

  "Just look at the screen and tap the remote control device with your finger, and the crops in the field can be irrigated precisely." Chen Zhen, a researcher at the Institute of Farmland Irrigation, Chinese Academy of Agricultural Sciences, said that the system combines drones, Internet of Things, self-propelled Combined with new agricultural technologies such as sprinklers, modern irrigation systems are used to carry out precise and efficient management of field water and fertilizer, and to realize digitalization and intelligence of agricultural irrigation information.

  "Because the moisture content of different plots is different, the 86 sprinklers on the sprinkler can be set to different flow rates, and the irrigation can be precisely variable according to the needs of the crops." Chen Zhen said that this technology saves water and fertilizer, and has low labor costs. The development direction of water efficient irrigation technology provides important support for promoting agricultural production, efficiency and industrial development.

He said that in the future, the system will be gradually put into the market to effectively help Henan increase grain production and income.

  As the only research institution specializing in drip irrigation and sprinkler irrigation technology in the country, precise irrigation has been the goal of the institute for more than 60 years.

As early as 1990, the former director Jia Dalin proposed to improve the utilization rate and efficiency of agricultural water use and take the road of water-saving agriculture, which is the fundamental way to increase grain production in the long run.

  Today, a new generation of scientific researchers such as Chen Zhen is focusing on the research and development of new agricultural technologies, making more and more "black technologies" appear in the Central Plains, and the grain yield per mu has also risen from 100 to 200 catties in the 1950s and 1960s. of thousands of pounds.

  Huang Xiuqiao, senior chief scientist of the water-saving and high-efficiency irrigation technology and equipment team of the Institute of Farmland Irrigation, Chinese Academy of Agricultural Sciences, said that in the next step, the team will shoulder the national water-saving agricultural technology and equipment research and development mission, inherit the scientific research spirit of the older generation of scientists of the irrigation institute, and focus on agriculture with one hand. Tackle key issues in water-saving technology, focus on the transformation of water-saving technology and equipment achievements, and help revitalize the development of water-saving agriculture in rural areas in the new era.
