| 喷灌设备发展趋势 Development Trend of Sprinkler Irrigation Equipment 喷灌设备向下列方面发展： Sprinkler irrigation equipment has been developed in the following areas: ①提高喷灌设备的综合利用率。除喷水灌溉外，还用于施化肥、洒农药、防霜冻、夏季降温、环境卫生等。 Improve the comprehensive utilization rate of sprinkler irrigation equipment. In addition to sprinkler irrigation, it is also used for fertilization, pesticide spraying, frost prevention, summer cooling, environmental sanitation and so on. ②提高喷灌均匀度和降低喷灌强度，降低能耗。如采用压力为0.2～0.25兆帕、强度为2～5毫米/小时的喷头作微喷慢灌。 (2) Improve sprinkler irrigation uniformity and reduce sprinkler irrigation intensity, and reduce energy consumption. For example, sprinklers with pressure of 0.2-0.25 MPa and intensity of 2-5 mm/h are used for micro-sprinkler slow irrigation. ③实现喷灌设备的自动化管理。如利用土壤湿度计和传感器系统，在土壤湿度变低或超过预定范围时自动开动或关闭喷灌机；根据系统内发出的故障信号，或在一个灌溉程序结束时发出的信号，使供水设备自动停机；固定式喷灌系统由程序自动控制仪操纵，实行编组轮流喷灌等。 (3) Realize the automatic management of sprinkler irrigation equipment. For example, using soil hygrometer and sensor system, the sprinkler can automatically start or close when the soil humidity becomes low or exceeds the predetermined range; according to the fault signal issued in the system or the signal issued at the end of an irrigation program, the water supply equipment can automatically stop; the fixed sprinkler irrigation system is operated by the program automatic controller, and the grouping rotation sprinkler irrigation is implemented. |
