内蒙古赤峰市红山区建新机械厂,经五年努力,研制成功2BF—1型手动播种施肥器,并获国家专利。该机施肥量(1～30克)、深度(1～18厘米)、播种量可调,施肥、播种、覆土既可同步一次完成,也可单项运用,能满足农艺上各种要求,与手工挖坑施肥相比。可节省化肥30％～60％,节省劳力50％,提高工效3～4倍。使用该机作业从根本上解决了手动机械施肥不能同时定 Hongshan District, Chifeng City, built a new machinery plant, after five years of hard work, the successful development of 2BF-1 type manual sowing fertilizer, and won the national patent. The amount of fertilizer (1 ~ 30 grams), depth (1 ~ 18 cm), adjustable seeding rate, fertilization, sowing, soil cover can be completed simultaneously, but also can be used individually, to meet the various requirements of agronomy, Digging compared to fertilization. Can save 30% to 60% fertilizer, labor-saving 50%, improve work efficiency 3 to 4 times. Using this machine operation fundamentally solved the manual mechanical fertilization can not be set at the same time
