轻、小型移动式喷灌系统,与固定式系统相比,具有所需原材料和设备少,田间工程量小,投资少,建设速度快等优点。几年来,在各地得到了较多的应用。但是,由于配套等方面的原因在使用上存在不少问题。为探讨轻、小型机组的合理配套与使用,考核其生产能力,我们选择了4CP和华北12C喷灌机各一套进行了田间生产试验。一、试验概况: 试点选择在天津市东郊区新立村公社崔家码头大队,这是一个种植蔬菜的园田队。水源是河水,喷灌机从田边渠道中提水。两套机组的设备及布置方式见表1。
Light and small mobile sprinkler system, compared with the fixed system, with less raw materials and equipment required, the field of small quantities, less investment, construction speed and so on. Over the past few years, more applications have been around. However, there are many problems in the usage due to the matching and other reasons. In order to explore the reasonable matching and use of light and small units and assess their production capacity, we chose 4CP and one set of North China 12C sprinklers for field production test. First, the test profile: Pilot selection in the eastern suburbs of Tianjin Village Legislature Cui Jia Pier brigade, which is a plantation vegetable garden team. Water is water, irrigation machines from Tanabe channels in the water. The equipment and layout of the two units are shown in Table 1.
