摘　　要：合理布置管网是微喷带灌溉工程效益发挥的基础,结合工程实践,对微喷带单控轮灌模式(SH)、辅管轮灌模式(AP)和支管轮灌模式(BP)的布置形式和适用条件进行了分析。结果表明:SH模式单位面积投入低,结构简单,适用于小面积微喷带灌溉;AP模式既具有经济性,又兼顾了机械化作业,同时还不受种植结构调整影响,适用于面积较大的地块;BP模式系统设备使用寿命长,后期投入少,适用于大面积、规模化节水灌溉工程。Rational pipe network is the base work to bring the benefit of micro-spring hose irrigation. In this paper, the layout form and application condition of three different engineering application modes of irrigation pipe network in micro-spring irrigation, such as rotation irrigation with separate micro-spraying hose (SH), auxiliary pipe (AP), and branch pipe(BP) were analyzed combined with engineering practice. The results show that SH suites for small area for its low investment and simple construction;AP, which is not only economic, but also beneficial to mechanizing farming, has little effect on planting structure adjustment and suites for medium area; while BP, which characterizes with its longer service life and lower additional investment, suites for larger area water saving irrigation project.
