Abstract Large scale gutter connected glass greenhouse has large monomer scale and strong ability for environment regulation.Soilless culture technology is generally adopted,which can break through the constraints of resources and environment,and greatly expand the possibility boundary of agricultural production.These greenhouses are typical representatives of modern facility planting industry and recently have been rapidly developed in China.Based on investigation of existing situation,and combined with document analysis,this paper summarized the development characteristics of large scale gutter connected glass greenhouses in recent years,such as regional distribution expanding to the central and western regions,structure standardization,equipment localization,and management digitization,etc.The paper also analyzed the existing defect sites in scientific planning and top-level design during development process,andsome problems as:key core technology and equipment mainly relying on import,low unit output rate andhigh operating cost,affecting the efficiency and sustainability of greenhouse production,etc.Besides,the paper put forward suggestions for future development,including selection of scientific and reasonable site,construction according to local conditions,moderate strict approval,amplifying research and development for key technology,reducing investment and operating cost,strengthening personal training,focusing on brand building,and enhancing ability for achieving sustainable development,etc.
