A kind of foundation structure in greenhouse is to provide the effect of a structurally stable entire greenhouse assembly of support; Combination including a cylindrical body and a plurality of fixators. Body defining has a chamber and is formed in the opening at chamber both ends, for concrete injecting chamber; The setting in fixator system parallel what body axis direction is in chamber. Fixator has the first end and second end for stretching out ontology; And pillar of the first end to combined greenhouse, and collectively form a greenhouse assembly.一種溫室之基礎結構,係提供一結構穩固的支撐整個溫室總成之作用;包括一筒狀本體和複數個固定器的組合。本體界定有一腔室和形成在腔室兩端的開口,供混凝土注入腔室;固定器係平行於本體軸線方向的設置在腔室內。固定器具有伸出本體的第一端和第二端;以及,該第一端用以組合溫室之支柱,而共同構成一溫室總成。
