The invention is a structure improvement of a portable hydroponic vegetable cultivation device, especially a cultivation device in which a cultivation container can be easily separated from the cultivation device and taken away together with the vegetables in the cultivation container. The culture device is obliquely locked on the culture device and includes a first and second cup body for single use, the first and second cup bodies have a first and second cup wall and a first and second cup body Two cup bottoms, the second cup body is disposed below the first cup body. The bottom of the first cup has a planting hole for placing a porous carrier for cultivating vegetables. The second cup wall has a drain hole, and a drain pipe is inserted into the drain hole, so that vegetables can grow in the first cup body. Such a one-time use of the culture container can achieve the effects of simplifying harvesting, reducing the cleaning and maintenance cost of the container, and ensuring that the nutrition is not lost after the vegetables are harvested.本發明係一種便攜式水耕蔬菜培養裝置的結構改良，尤指培養容器可輕易從培養裝置上分離，連同培養容器內蔬菜一起帶走的培養裝置。該培養裝置係斜向卡定於培養裝置上，包含一次性使用的一第一、第二杯體，該第一、第二杯體具有一第一、第二杯壁及一第一、第二杯底，該第二杯體設置於該第一杯體下方。其中該第一杯底具有植栽孔，供放置培養蔬菜之多孔載體。該第二杯壁具有排水孔，該排水孔插接一排水管，使得蔬菜能成長於該第一杯體。如此一次性的使用培養容器，可達到簡化採收、降低容器清潔維護成本及確保蔬菜採收後營養不流失的功效。
