小麦、玉米是华北地区的主要粮食作物,种植制度以套种为主。套种小麦主要有:七尺半畦小麦—玉米—豆类三种三收,四尺半至六尺畦小麦—玉米两茬套种两种种植形式。其主要优点是土地和光能的利用率高,能够争取季节,错开农时,有利于夏粮和秋粮的平衡增产。本地区机械化种植冬小麦生产中普遍采用筑埂、撒化肥、旋耕、播种、镇压等作业分段进行的机械化工艺,由于机组需要五次进地作业,要求配备的机具数量多、能源消耗多、成本高、
Wheat and corn are the staple food crops in North China. The planting system is dominated by intercropping. The intercropping wheat mainly includes three types of three-cropping wheat, corn-bean three-crop, four-foot-half-six-heel wheat-corn two-cropping in two planting forms. Its main advantage is the high utilization rate of land and light energy, can win the season, stagger the agricultural period, is conducive to the balanced increase of summer grain and autumn grain. Mechanized planting winter wheat production in the region commonly used mechanized technology, such as building 埂, sprinkle fertilizer, rotary tillage, sowing, repression and other operations segment, as the unit needs to enter into the work five times, requiring a large number of equipment, energy consumption, high cost,
