A vegetable preservation and growing case includes a thermally-insulated case body for vegetable growing or preservation. An electrical control component is electrically controlling the thermally-insulated case. A pipeline component is circularly supplying a nutrient solution to the thermally-insulated case body under an action of gravity. The preservation and growing case allows the freshness of a vegetable to be preserved for an extended period of time, has a simple structure, and is easy to maintain.
