涌泉灌溉毛管长度与布设方式的确定

The Length of Branch Pipe and the Best Way to Decorate in Bubble Irrigation Engineering Design Research

涌泉灌是由微管代替滴头出流的一种灌水方式,适用于地形复杂的丘陵地区,近年来被广泛应用于果树灌溉。为此,结合山西省晋城市陵川县丈河村果园灌溉工程,介绍了在涌泉灌溉下毛管极限长度的计算方法,并且通过对同一地块下不同毛管布置形式的水头损失对比,得出结论为:在同一地块下,采用支管双向出流时,比单向出流的情况要更节水。上述结论可作为梯田果园涌泉灌溉工程设计的参考。

spring irrigation , it is by the micro-irrigation pipe instead of drop head out of the flow of a way to infuse water, it is suitable for the complex terrain of mountain region, it is widely used in fruits tree irrigation in recent years. Taking shan xi jin cheng zhang he river village orchard irrigation project as example ,it introduces the length of the capil-lary under the spring irrigation method , and based on the same plots under different cloth pipe head loss in the form of comparative analysis , obtained in the same block , using capillary two-way flow , 62 .8% less than one-way flow under the condition of the head loss of conclusion , the conclusion can be used as a mountain terraced orchard irrigation engi-neering design reference .
