摘 要:针对草坪喷灌喷洒时间短,喷洒次数多的特点,在地埋式伸缩喷灌系统上,对传统喷灌系统设计的参数进行水力学试验,调大了经济流速,使得系统中管材尺寸缩小,降低投资成本,以便在用水紧缺的广大地区,能够较快发展低成本的节水型草坪喷灌系统。经过四年试喷,在喷洒效果良好的情况下,水头损失有所增加,但水泵选用型号仍为同一型号。节约材料投资25.4%,具有明显的成本优势。As sprays time was short in lawn sprinkling irrigation and times of spray were greater,on the basis of the geography type flexible sprinkling irrigation system, research on the parameter designed to improve sprinkling irrigation system was carried out to adjust the large economic velocity of flow , make the size of pipe in the system shrink, reduce the cost of investment,for 4 years.Model number of water pump chosen was still as the same one,but it saved the 25.4% of investment. So it showed apparent superiority greatly of its cost. In order to use in water short supply area, we developed low water-saving lawn sprinkling irrigation system of cost comparatively fast.
