| 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 hygiene, etc. 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, sprinkler irrigation machine can be automatically turned on or off when soil humidity becomes low or exceeds the predetermined range; water supply equipment can be automatically shut down according to the fault signal issued in the system or at the end of an irrigation program; fixed sprinkler irrigation system can be operated and implemented by a programmed automatic controller. Group rotation sprinkler irrigation, etc. |
