Abstract: Representing the peak of protected horticultural research and technical application, integrating the advanced achievements and pointing out the developing direction of protected horticulture, modern greenhouses can play a pioneer and demonstration role for the popularization of equipment high-tech into other facilities. Through article reference study and in situ investigation in the horticulture developed countries, the authors summed up the developing trend of world greenhouse equipment and technology based on the analysis of extension features, technique innovation and research hot points. Accompanied with the analysis of developing trend and main challenge Chinese horticulture faced to, the authors put forward suggestions such as improving the status of protected horticulture within agriculture, stepping up equipment technique application and scale, insisting on the prescience and pertinence of research work, increasing the research level of common science and all application study within the industrial chain, and changing the developing style of equipment technique, in order to provide guidance and reference for Chinese greenhouse horticultural improvement and development.
