由于李登海在玉米育种与栽培上成绩突出,对国家贡献大,1983年,经上级有关部门批准,李登海被破格选拔为农艺师,他的身份也由一个农民转为国家正式干部。1984年,李登海又调任莱州市科委当副主任,全家人户口农转非。也正是这一年,莱州市农村实行了土地联产承包责任制,农科队的实验田已被承包到户,后邓村的农科队解散了。 Since Lee Teng-hai made outstanding achievements in maize breeding and cultivation and made great contributions to the country, Li Denghai was singled out as an agronomist in 1983 after approval by the higher authorities. His identity was also changed from a farmer to a national official cadre. In 1984, Li Denghai was transferred to Laizhou Science and Technology Commission as deputy director, the whole family accounts of farmers to non-agricultural. It was also this year that the contract responsibility system of land contract was implemented in the rural areas of Laizhou City. The experimental fields of the agricultural teams were contracted to households, and the agricultural teams in Dengcun were dissolved.
