温室智能灌溉控制系统应用研究与展望

Application Research and Prospect of Intelligent Irrigation Control System in Greenhouse

目前,智能灌溉控制系统多采用定时控制,即达到开启时间设备工作,达到灌溉时长设备停止,在一定程度上实现了自动化灌溉,但由于作物在不同生长时期的需水量不同,灌溉控制系统难以生成与作物需求一致的灌溉方案。我国温室智能灌溉技术起步较晚,还没有大范围应用,已经采用智能灌溉的地区,其控制方式及控制策略也不同。以智能灌溉控制系统为出发点,阐述了温室智能灌溉控制系统的组成、问题等,并展望了其未来的发展趋势。

At present,intelligent irrigation control system mostly adopts timing control,that is,equipment works when it reaches start time,and stops when it reaches irrigation duration.Automatic irrigation has been realized to a certain extent.However,due to differ-ent water requirements of crops in different growth periods,it is difficult for irrigation control system to generate irrigation schemes con-sistent with needs of crops.Intelligent irrigation technology of greenhouse has started relatively late in our country,and has not been widely used,and its control mode and control strategy are different in those areas where intelligent irrigation has been used.Taking in-telligent irrigation control system as starting point,composition and problems of greenhouse intelligent irrigation control system were ex-pounded,and its future development was prospected.
