摘要
针对微灌自动控制系统日益普及的现状,在分析了手动及自动控制微灌系统管网布置、轮灌组划分特点的基础上,以实际工程为例,详细分析了两种系统设计的区别,并经过系统投资比较得出,虽然自动控制微灌系统增加了自动控制设备,但由于轮灌组和灌水小区的分散布置,可以做到两种灌溉系统初始投资相近。
Based on the analysis of characteristic of pipeline net layout mode and alternate irrigation team division of manual control and automatic control drip irrigation system, the difference of design method between the two systems was studied in detail in this paper. Through comparing investment of the two systems, the author put forward that though the investment for automatic control devices was added to the automatic control system, investments of the two systems can be near the same for the dispersive layout of alternate irrigation team and irrigation unit.
