河北省大曹庄农场是农林部1978年安排引进应用国外大型喷灌机的试点之一。引进应用的目的:一是通过实践了解这种先进灌水技术装备的结构、性能、原理,仿制、创制国产大型喷灌机。二是通过较大面积的田间试验,考察大型喷灌机组在我国农业发展现阶段的适应性、可行性及其节水、增产、能耗等方面的效益,为发展喷灌宏观决策提供依据。 大曹庄农场1978年引进美国“伐利”喷灌机8台,其中电动2071型7台,水动1260型1台。到1988年已拥有喷灌机19台,后增加的机型为:国产园型喷灌机7台,平移式喷灌机2台,美制林塞800米平移式喷灌机2台。喷灌控制面积1.4万亩,占全农场耕地的73%,基本
Hebei Province, Cao Cao farm is the Ministry of Agriculture and Forestry in 1978 arrangements for the introduction of large-scale irrigation pilot application abroad one of the pilot. The purpose of the introduction of the application: First, through the practice of this advanced irrigation technology and equipment to understand the structure, performance, principles, imitation, creating large-scale domestic irrigation. The second is to test the adaptability and feasibility of large-scale sprinkler units at the present stage of agricultural development in our country and the benefits in terms of water saving, stimulation and energy consumption through a large area field experiment, and provide the basis for the development of macro-control decision-making. Large Caozhuang farms in 1978 the introduction of the United States, “cutting profits” Irrigation 8, of which 2071 Electric 7, 1260 hydrodynamic 1 Taiwan. By 1988, there were 19 irrigation sprinklers, after which 7 models were domestic garden irrigation machines, 2 shift irrigation machines and 2 American Linsei 800-meter shift irrigation machines. Irrigation control area of 14000 acres, accounting for 73% of the farmland, basic
