近几年,在广西百色、海南琼海、内蒙古通辽、河北吴桥、新疆霍城等全国不少市县的田间,冒出了这样一台样貌颇为奇特的农机。这台“大块头”是履带底盘,车头前挂着的灭茬器可以灭茬秸秆还田;后半身高悬着一排垂直螺旋钻头,装配有起垄清沟、施肥播种、表土平整镇压等功能,可以一次性完成传统的犁、耙、碎等作业程序。在现场可以看到,螺旋钻头启动后,垂直深旋入土下30~50厘米,将田间原本板结的地面粉碎成颗粒状,让土壤自然悬浮成垄,可直接播种作物。这种农机的耕深不仅比 In recent years, Baise in Guangxi, Hainan Qionghai, Inner Mongolia Tongliao, Hebei Wuqiao, Xinjiang Huocheng many cities and counties in the country, cropped up such a strange appearance of agricultural machinery. This “big head” is a crawler chassis, the front of the front of the stubble stubble stubble can be stubble back to straw; the rear halfway hanging a row of vertical helical drill, equipped with furrowing ditch, fertilization sowing, topsoil formation suppression and other functions , You can complete the traditional one-time plow, rake, broken and other operating procedures. At the scene, we can see that when the auger bit is started, the screw is screwed into the soil 30 to 50 centimeters in the vertical direction. The originally crushed ground in the field is crushed into a granular form, and the soil is naturally suspended into a ridge. The crops can be directly sown. The plowing depth of this kind of farm machinery is not only more than that
