The ＂grain＂ policy of big countries ｜ Smart irrigation New technical achievements ＂bright eyes＂ help increase grain production and income

CCTV News:The reporter learned from the research institution specializing in drip irrigation and sprinkler irrigation technology in China — — According to the research institute of farmland irrigation of China Academy of Agricultural Sciences, this year, China has popularized and applied the new intelligent irrigation technology in Henan, Shandong, Hebei and other major grain producing areas, with a total area of more than 10 million mu, which has promoted the local grain income.

Not long ago, the wheat in Xinxiang Comprehensive Experimental Base of the Institute of Farmland Irrigation of China Academy of Agricultural Sciences ushered in a concentrated harvest period. Judging from the yield, the average yield per mu is about 600 kg by using traditional irrigation methods, but after using intelligent irrigation technology, the yield per mu can reach 700 kg, an increase of about 15%.

Transshipment by farmland irrigation research institute Division:From the perspective of water-saving effect, after adopting drip irrigation technology, water will be saved by 20%— 30%, and this year’s effect is even better, reaching more than 30%.

Such a good water-saving effect can not be achieved without the precise variable irrigation system used since the spring pipe. As early as April this year, the reporter recorded the "bright eye" performance of this intelligent system in the field.

Fan Yongshen, a researcher at the Institute of Farmland Irrigation, China Academy of Agricultural Sciences:Large sprinkler has the characteristics of automatic walking and even irrigation.

The researchers told reporters that the water flow speed of 68 sprinklers on the sprinkler can be automatically adjusted according to the water demand in different regions.

Marco, Institute of Farmland Irrigation, China Academy of Agricultural Sciences:The precision variable irrigation system mainly uses unmanned aerial vehicle to obtain the prescription map of field irrigation, and the prescription map can be automatically fed back to the large sprinkler. When the sprinkler goes to each position, it can accurately control the opening of the sprinkler, including the speed of the sprinkler, and realize the precise control of variables.

Guo Zhimin, a farmer in Xinxiang County, Henan Province:I can use my mobile phone to control the operation process of the whole sprinkler. Compared with the traditional flood irrigation in our family, one acre of land can save water by 20-mdash; 30 square meters.

This new intelligent irrigation technology has been popularized and applied in Henan, Shandong, Hebei and other major producing areas this year, covering an area of more than 10 million mu.

Zhou Guomin, Director of farmland irrigation research institute:Smart irrigation system will produce more agricultural products with the least amount of water, and make greater contributions to ensuring national water security and food security.
