1984年11月18日至19日,由河北省科委主持,在大曹庄农场召开了“引进大型喷灌机应用试验研究鉴定会”。参加鉴定会的有大专院校、科研、生产管理及使用等17个单位的代表共42人。这次鉴定会对大曹庄农场引进大型喷灌机的应用试验研究成果作了评价。 1978年,河北省接受了原农林部给的引进圆形喷灌机试验和测定任务。由省科委组织原省农业局农垦处,省机械所、省水科所、大曹庄农场、华北农机学院,河北农大、新乡灌溉研究所等单位成立了会战组。原省农业局农垦处为组长单位,以大曹庄农场为试验基地。当年夏季,引进美国“伐利”圆形喷灌机8台,对大曹庄农场原畦灌系统进行改造,开展大型喷灌机的应用试验研究工作。在应用试验研究中,本着“一学、二用、三改、四创”的精神,做了大量的消化
November 18, 1984 to 19, presided over by the Hebei Provincial Science and Technology Commission, held a large farm in Caozhuang “Introduction of large-scale irrigation pilot application of appraisal ”. A total of 42 representatives from 17 institutes including universities, scientific research, production management and use participated in the appraisal meeting. The appraisal will evaluate the application test results of large-scale sprinkler irrigation at Daocaozhuang Farm. In 1978, Hebei Province accepted the former Ministry of Agriculture and Forestry Department to introduce the test of circular irrigation and testing mission. By the provincial Science and Technology Commission organized the former provincial Bureau of Agriculture Reclamation Department, the provincial machinery institute, the provincial water science institute, Daocaozhuang farm, North China Agricultural Machinery Institute, Hebei Agricultural University, Xinxiang Institute of Irrigation and other units set up a battle group. Agricultural Bureau of the former provincial Bureau of Agricultural Reclamation as the unit leader, with large Caozhuang farm as a test base. In the summer of this year, 8 circular irrigation sprinklers from the United States were introduced to transform the original irrigation system in Daocaozhuang Farm and carry out experimental research on the application of large irrigation sprinklers. In the application of experimental research, in the spirit of “one study, two uses, three changes, four create ”, made a lot of digestion
