A hydroponic vegetable cultivation device mainly comprises a plurality of tank bodies, a plurality of cultivating shelves arranged on the tank bodies and provided with adsorption pieces, and a cover body arranged above the tank bodies. The cultivating shelves connected to each other are provided with a plurality of large-sized and small-sized brake rods which can be mutually restrained, juxtaposedly approached or opened from each other, so that the cultivating shelves can be moved along the tank bodies, and the large-sized and small-sized brake rods can be opened one by one when the cultivating shelves are moved to proper positions. A culture solution is received in the tank bodies, vegetable seeds are placed on the adsorption piece of each cultivating shelf, and the adsorption pieces of the cultivating shelves are utilized to absorb the culture solution, thus to constitute the cultivation and planting of hydroponic vegetables. In addition, the large-sized and small-sized brake rods are opened one by one by pulling the cultivating shelves according to a cultivation schedule, so that all cultivating shelves can be opened at a distance therebetween to be beneficial to the growth of the hydroponic vegetables.一種水耕蔬菜栽培裝置,主要係包含複數之槽體及置於該等槽體設有吸附件之複數個栽培架,以及置於槽體上方之罩體。其中,該等栽培架係相互連接,其設有複數相互牽制,且可相互並排靠攏或拉開之大、小制動桿,使栽培架得以沿槽體移動,且於移動至適當位置時得以將大、小制動桿逐一拉開。俾於槽體置入培養液,並於各栽培架之吸附件放置蔬菜種子,藉由吸附件吸附培養液以構成水耕蔬菜之培植栽種,且依栽種的日期將栽培架拉動使大、小制動桿逐一拉開,進而使各栽培架間拉開距離,以利於水耕蔬菜之成長。A‧‧‧槽體B‧‧‧栽培架C‧‧‧罩體1‧‧‧水平面11‧‧‧突點2‧‧‧承部22‧‧‧卡勾3、3a、3b、3c‧‧‧制動桿31‧‧‧扣持部4‧‧‧肋條41‧‧‧剖槽
