近年来,生产试验证明,移栽是达到高产的一项重要措施。因此,玉米移栽技术逐渐推广,移栽的面积逐渐扩大。如山西、河南、河北等地先后经过玉米移栽获得了增产。北京郊区通过生产实践证明,移栽的玉米一般比直播玉米增产20%左右。但目前尚无移栽机具的情况下,用人工移栽,效率低、劳动强度大。为此,我所于一九七三年年初同本市朝阳区祖国农机修配厂、朝阳区农机局,实行领导、工人、技术 In recent years, production tests have proved that transplanting is an important measure to achieve high yield. Therefore, corn transplanting technology is gradually promoted, transplanting area gradually expanded. Such as Shanxi, Henan, Hebei and other places have been corn transplanting has been increased. Beijing suburbs through production practices have proved that transplanting of corn generally increased by about 20% than direct seeding corn. However, there is no transplanting equipment, the use of artificial transplanting, low efficiency, labor-intensive. To this end, I was in early 1973 with the city of Chaoyang District, the motherland farm machinery repair plant, Chaoyang District Agricultural Machinery Bureau, the implementation of leadership, workers, technology
