The cold air that the present invention is and external short distance is concentrated protect crop safety warming loss is kept simultaneously, is minimized it, according to crop characteristic adjust heating distance and daylighting the compound single thermoplastic materials of energy saving type of best condition of growth is embodied about Avens, in detailed installation, with most of bases of same layer interval purchase upper layer on the basis of upper, we is Dragon Boat Festival portion. Entry and exit that outside is made of major architectural, central portion, deadline are formed continuously, and above-mentioned entry and exit system will be in the first polybag that be installed on main frame, and form Dragon Boat Festival center singly lists vertical text, and above-mentioned central portion is external. It is connected with the main frame of rotating frame, so that the speed in photo-thermal portion is adjusted the height adjustment in photo-thermal portion and the open area of Inner plastic, form most starting frames. The above-mentioned deadline by by the inside for second fixed plastics being mounted in main frame, is made of effective port.
