一个典型滴灌系统(图1.1)的总体规划,是确定由毛管、支管以及与其连接的干管构成的广阔的管路网。毛管和支管构成这个管路系统的基本小区。滴灌系统设计中的一个主要问题是选择最佳小区大小和数目,以使运行经济和高效率。为此,正确地选择自动化设备的种类和自动化程度是很重要的,这种设备 The general plan for a typical drip irrigation system (Figure 1.1) is to identify a vast network of pipelines consisting of capillary tubes, branch pipes, and the main pipe to which they are connected. The capillary tube and the branch pipe form the basic cell of this piping system. A major problem in drip irrigation system design is the selection of the best cell size and number to make the operation economical and efficient. For this reason, it is important to select the type and degree of automation of the automation equipment correctly
