陕西省黄龙县地处黄土高原丘陵沟壑区,平均海拔1 100 m,属温带大陆性半湿润季风气候,耕地土层深厚,质地疏松,通透性好,适宜玉米种植。全县常年粮食种植面积18万亩,其中玉米达14万亩,是全县第一大粮食作物。2009年实施玉米高产创建以来,累计建设万亩示范片13个,千亩方20个,百亩公关田30个,总面积14万亩。通过几年政策的扶持,新技术的示范,玉米“四化一高”(品种良种化、耕作机械化、除草化学化、施肥配方化和合理增高种植密度)技术的推广,各项关键配套增产措施的应用,高产创建活动取得了显著成效。
Huanglong County, Shaanxi Province is located in the hilly and gully regions of the Loess Plateau, with an average elevation of 1 100 m. It belongs to a temperate continental semi-humid monsoon climate. The arable land has a deep soil layer with loose texture and good permeability and is suitable for corn planting. The county perennial grain planting area of 180000 acres, of which 140000 acres of corn, is the county’s largest food crop. Since the establishment of high-yield corn in 2009, a total of 13,000 mu demonstration plots have been built, 20 of which are mu-mu and 30 of which have a total area of 140,000 mu. Through years of policy support, demonstration of new technologies, popularization of corn technology, popularization of farming, mechanization of farming, herbicidal and chemical transformation, fertilization formulation and reasonably increasing planting density, the key supporting facilities The application of stimulation measures and high-yield creation activities have achieved remarkable results.
