Abstract: Chinese greenhouse has had a great development in the past five years and a lot of greenhouse manufacturers can design, manufacture and install a whole set of greenhouse and the equipment associated with it by themselves. As we have no native standards to identify the different greenhouse models, which are mostly identified by the greenhouse builders or factories, it is very difficult for greenhouse users and greenhouse managers or researchers to distinguish the difference among the greenhouses. In some cases, one type of greenhouses has several different names or models. So, it is necessary to have a ruler how to identify the greenhouse models. In this paper, based on the native plastic tunnel standard and the situation of greenhouse identification methods mostly used in China, we have put forward a ruler to identify the greenhouse, plastic tunnel and solar plastic greenhouse which is specially developed in China respectively. It will form a whole system for greenhouse identification.
