小麦耗水量大,生长期基本处于旱季,用水几乎是靠灌溉解决。北京又是缺水地区,因此,粮食作物产业技术体系创新团队自成立以来,一直以节水为突破口,在小麦生产中因苗因墒管理和喷灌施肥技术等项目上取得了丰硕的成果。“千斤村”走上节水高效路房山区窦店村是北京市粮食生产的高产典型,2011年,在北京市农业技术推广站技术示范带动下,窦店村100公顷小麦667米2产超过500千克,自此,窦店村成了全市标杆性的千斤村。但是,高产的获得离不开水肥的投入,每667米2常年用水投入要200米3、养分投入需要45.00千克。为了进一步挖掘小麦节水省肥的潜力,树
Water consumption of wheat is large, the basic growth period in the dry season, water is almost rely on irrigation. Beijing is also a water-scarce region. Therefore, since its establishment, the innovation team of technology system of grain crop industry has taken water saving as a breakthrough point and achieved fruitful results in the wheat production due to the management of soil moisture and sprinkler irrigation and fertilization technologies. “Guijin village ” embarked on water-saving and efficient road Fangshan Dou Doucun is Beijing’s high-yielding food production typical, in 2011, Beijing Agricultural Technology Extension Station Technology Demonstration Driven, Doudian village 100 hectares of wheat 667 m 2 Producing more than 500 kilograms, since Dou Dian Cun became the city’s benchmark jack village. However, high-yield access is inseparable from the input of water and fertilizer, every 667 m 2 annual water input to 200 m 3, nutrient input requires 45.00 kg. In order to further tap the potential of saving water and fertilizer, trees
