Experimental big -arch shelter of using

The utility model discloses an experimental big -arch shelter of using, including greenhouse and shed cloth, greenhouse is extending structure, greenhouse includes a plurality of extension means thatconnect gradually, the semi -circular structure that extension means constructed for the hexagon casing extends, relative both sides face is two adjacent extension means's sharing side respectively around the middle extension means, greenhouse is constructed by the two -layer face structure that covers inside and outside front and back both ends side and the connection of sharing side. The utilitymodel discloses an experimental big -arch shelter of using can make things convenient for the realization to fold and expand very much, can directly be used for multinomial experiments such as experimental plot rain -proof, shading, accuse temperature, covers and not covers and switch the convenience between the state, can change the big -arch shelter easily between different experimental plots as required, self the suppo
