In order to solve the common problems in existing solar greenhouses such as simple equipment, poor environmental regulation and cold prevention ability, as well as low land utilization rate and labor productivity, a new type of greenhouse, the assembly type solar double effect greenhouse was built and researched. There are two kinds of structures for the assembly type of the solar double effect greenhouse: internal insulation greenhouse and external insulation greenhouse. Both the internal and the external insulation greenhouses are fully transparent greenhouses with galvanizing steel structures as framework. The main test indexes are, air minimum temperature, daily average temperature, light intensity, relative air humidity, crops yield per plant and yield per unit area. The conclusion is, the assembly type of the solar double effect greenhouse improved environmental conditions greatly, and improved the capacity of both cold and disease prevention, and increased both production and income. The research and a
