The present invention relates to a plastic greenhouse. According to the present invention, a prefabricated plastic greenhouse (1) allowing a complete opening and closing operation comprises: a left support frame (100) stood on the ground a right support frame (200) stood at a regular interval to be symmetrical to the left support frame (100) multiple arch-shaped roof frames (300) having both ends respectively coupled to the left and right support frames (100, 200) to form the structure of the plastic greenhouse, and arranged at equal intervals a connecting and fixing block (400) connected to allow the left support frame (100) and the right support frame (200) to be fixed to the ground and plastic (500) put on the outer side of each frame. The left and right support frames (100, 200) further comprise: a fixing part (600) being able to fixing both ends of each arch-shaped roof frame (300) and a first combining part (700) allowed to be fixed to the connecting and fixing block (400). The connecting and fixing block (400) further comprises: a base (410) made of concrete, a connecting frame (420), and a second combining part (430). In addition, the prefabricated plastic greenhouse (1) allowing a complete opening and closing operation can completely open and close the plastic (500) according to the demand of a user. Accordingly, the prefabricated plastic greenhouse (1) in the present invention is easily installed and maintained due to a simple structure, and can completely open and close the plastic (500) according to a cultivated crop or natural environment. Therefore, the efficiency of the prefabricated plastic greenhouse (1) is enhanced, and an optimal cultivation environment can be created according to a cultivated crop.COPYRIGHT KIPO 2016본 발명은 비닐하우스에 관한 것이다.본 발명에 따르면, 전면 개폐가 가능한 조립식 비닐하우스(1)에 있어서,지면에 세워지는 좌측 지지프레임(100)과 상기 좌측 지지프레임(100)과 일정 폭으로 대칭하여 세워지는 우측 지지프레임(200)과 상기 좌, 우측 지지프레임(100, 200)에 양 끝단이 각각 결합되어 비닐하우스의 구조를 형성하게 하는 등 간격으로 배치되는 다수개의 아치형 지붕프레임(300)과 상기 좌측 지지
