The invention relates to the plantation equipment field, in particular to an elevatable grape trellis used for a terrace. The elevatable grape trellis comprises a main trellis body, an anti-adhesion cover covering the main trellis body, a basin stand support table connected to the bottom of the main trellis body and an elevating device used for elevating the main trellis body. Space limiting rods used for erecting upward growth space of leaves are arranged between the top of the main trellis body and the anti-adhesion cover. The basin stand support table is connected with the main trellis body through an adjusting connection device capable of adjusting spacing distance. The adjusting connection device comprises two vertically-arranged hanging rods fixedly connected to the main trellis body, guide rods vertically connected to a table plate of the basin stand support table, and table plate elevating parts located in guide rails and used for pulling the guide rods to slide up and down. The grape trellis used for the terrace has following beneficial effects: the grape trellis is simple in structure and high in strength; the overall grape trellis is capable of ascending and descending at the same time so that fruits are conveniently picked up, pruned and tendrils can be adjusted; meanwhile, the overall grape trellis is independent from a glass room; and tendrils are limited into the anti-adhesion cover so that the structure of the glass room is not affected.
