摘要
基于植物本体的检测技术由于能够实时监测植物体内的水分状态,近年来在灌溉控制系统中得到了广泛的应用。从检测方式分类、检测方法、检测参数、检测仪器以及各种检测方法优缺点等方面综述了植物本体检测技术进展。首先,针对传感器与植物有无物理接触将其分为接触式和非接触式检测;其次,针对植物本体有无物理损伤分为破坏性和非破坏性检测;再次,针对测量参数不同分为实时检测技术(植物器官的测量)和非实时检测技术(植物生理响应测量);最后,对各种方法的优缺点予以比较并指出基于植物本体的检测技术是在线灌溉控制系统未来的发展方向。
Because plant-based sensing technology can real-time monitor the plant water status,it has increasingly been used in irrigation control systems in recent years.The plant-based sensing technology is reviewed from the aspect of measurement way classification,measurement method,measurement parameters,measurement instruments,the advantages and disadvantages of the methods.Firstly,in terms of the physical contact between sensor and plant,it is classify into contract and non-contact detection.Secondly,in terms of the physical trauma to the plant,it is classify into destructive and nondestructive detection.Thirdly,in terms of the real-time measurement,it is classify into online real-time and non-real-time detection.In the end,the advantages and disadvantages of all the methods are compared,and it is indicated that the plant-based detection are the future development trend for the online irrigate control systems.
