滴灌系统管路配置滴灌又称微喷,是一种利用微型喷头,将水一滴滴地直接送到植物根部区域,以达到灌溉效果的节水浇灌方式。滴灌系统管路配置包括主管——支管——喷灌管——滴头。大部分喷灌管的颜色为黑色,材质为碳纤维,可防止日照损坏。如果采用电磁阀来开启或关闭回路,整个自动滴灌系统则需融为一体,密不可分。为了提高绿化带和人行道内植物区、运动场所及公园景观效果,不使滴灌系统管路露出地表影响视觉和交通,通常把管路埋于地下深30厘米至50厘米。滴头则以30厘米至90厘米长的软管同支架或柱状物坚于地表,以确保向乔灌木,植被(草坪)供水。虽然地下滴灌系统成本较高,但因具有便利、耐用和节水的特点,已逐渐被大量采用并取代部分喷灌工程。它不受日照蒸腾及风等环境因素影响,据统计数据显示,节水一般可达35%至50%。实践证明,只有当滴头置于植物根部区域50%范围内,才能确保达到最理想的供水需求。地下铺设的滴灌管路需对滴头定期保养。PVC和PE管路及过滤器一般需每月固定冲洗并定期检查故障,防止植物根部因生长而堵塞滴头。对于盐碱地等特定地区,由于区域内水中含盐碱量高,若仅依靠对根部区域50%范围内给水,则明显不足。建议采用交错配置方式,以防植物根系枯死。
