内蒙古农机研究所、农机推广站和探矿机械厂共同研制成2BG-120A型谷物沟播机,于1991年11月在呼和浩特通过了内蒙古农牧业机械鉴定站的鉴定,并由内蒙古探矿机械厂投入批量生产。该机与8.8～11.0千瓦(12～15马力)小四轮拖拉机配套,可一次完成开沟、起垄、播种、种肥分施、覆土和沟底镇压6道工序。播种时把地表干土推到两侧作埂,再在湿土上开沟施肥、播籽,起到两犁探墒播种和种、肥分层的效果;垄沟与垄台有一定的高低差,垄沟易形成优化“小气侯”和集聚雨雪,有利于蓄水保墒。适合旱地、盐碱地、瘠薄地区小麦、大麦、谷子、高粱、玉米
Inner Mongolia Agricultural Machinery Research Institute, Agricultural Machinery Extension Station and Prospecting Machinery Factory jointly developed into 2BG-120A cereal ditch sowing machine, in November 1991 in Hohhot adopted Inner Mongolia Agriculture and Animal Husbandry Machinery Identification Station identified by Inner Mongolia Prospecting Machinery Factory inputs Mass production. The machine and 8.8 ~ 11.0 kilowatts (12 to 15 horsepower) small four-wheel tractor supporting, can be a complete ditching, Ridge, sowing, the kinds of fertilizer facilities, soil cover and ditch repression 6 procedures. Sowing the surface dry soil pushed to both sides of Zan, and then drenched in the wetland fertilization, sowing, played two plow soil moisture seeding and species, fertilizer stratification effect; ditch and ridge have a certain height difference , The formation of furrow easy to optimize “microclimate ” and gather rain and snow, is conducive to water storage and preservation of soil moisture. Suitable for dry land, saline land, barren land wheat, barley, millet, sorghum, corn
