| 滴灌系统主要由首部枢纽、管路和滴头三部分组成，图一1为滴灌系统示意图。 The drip irrigation system is mainly composed of the first hub, pipeline and emitter. Fig. 1 is the schematic diagram of the drip irrigation system. 1．首部枢纽：包括水泵(及动力机)、施肥罐、过滤器、控制与测量仪表等。其作用是 抽水、施肥、过滤，以一定的压力将一定数量的水送入干管。 1. Head hub: including pumps (and power machines), fertilizer tanks, filters, control and measurement instruments. Its function is to pump, fertilize and filter water, and to put a certain amount of water into the main pipe under certain pressure. 2．管路：包括干管、支管、毛管以及必要的调节设备(如压力表、闸阀、流量调节器 等)。其作用是将加压水均匀地输送到滴头。 2. Pipeline: including main pipe, branch pipe, capillary pipe and necessary adjustment equipment (such as pressure gauge, gate valve, flow regulator, etc.). Its function is to transport the pressurized water evenly to the dripper. 3．滴头：其作用是使水流经过微小的孔道，形成能量损失，减小其压力，使它以点滴的方式滴入土壤中。滴头通常放在土壤表面，亦可以浅埋保护。 3. Dropper: Its function is to make water flow through tiny channels, form energy loss, reduce its tianchuangd.89ix.comtianchuang.89ix.comtongfengqiw.89ix.comtongfengqi.89ix.comchuanxian.89ix.com pvcguanjian.89ix.compressure, and make it drip into the soil in a drip-by-drip manner. Droppers are usually placed on the surface of the soil and can be protected by shallow burial. |
