| 滴灌系统的组成 滴灌系统主要【压力补偿滴头】由首部枢纽、管路和滴头三部分组成。 The composition of drip irrigation system is mainly composed of the first junction, pipeline and drop head. 1．首部枢纽：包括水泵(及动力机)、化肥罐过滤器、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. The first pivot: including water pump (and power machine), fertilizer tank filter, control and measuring instrument, etc. The function is to pump water, fertilize and filter, and put a certain amount of water into the dry tube with 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 dry pipe, branch pipe, hair tube and necessary regulating equipment (such as pressure gauge, gate valve, flow regulator, etc.). The effect is to transport the pressurized water evenly to the tip. 3．滴头：其作用是使水流经过微小的孔道，形成能量损失，减小排气阀其压力，使它以点滴 的方式滴人土壤中。滴头通常放在土壤表面，亦可以浅埋保护。 3. Drop head: its effect is to make the water flow through a tiny channel, to form energy loss, and to reduce the pressure of the exhaust valve, so that it can drop into the soil in a drip manner. The dropper is usually placed on the surface of the soil and can be protected with shallow burial. 1. 水源 2. 水泵 3. 流量计 4. 压力表 5. 化肥罐 6. 过滤器 7. 干管 8. 流量调节器 9. 支管 10. 毛管 11. 滴头 12. 果树 13. 大田作物 Water source 2.

Drip irrigation system is an advanced irrigation method, a new type of low pressure water saving irrigation technique, which USES specially designed small diameter pipes with insert in advance which drip irrigation belt precision drop head, supply water and nutrient accurately crops. Since Israel knight fimm in 1965 since the invention of the technology, the application of drip irrigation belt is becoming more and more widely. It not only water, fertilizer, save labor, so as to relieve the contradictions of water, it can greatly improve the quality and yield of all kinds of crops. At the same time because of the atomizing nozzle 】 【 buried drip with most of the water pipe is buried underground, don't like flood irrigation canals, takes up a lot of arable land block built in the field more don't have special request for the terrain, to divide the 20-30 m block can also be normal application of drip irrigation belt, thus improve the utilization of land and scope of PE pipe, the output of per unit area increases. |
