Disclosed is a closed planting site at constant temperature and with movable planting frames, mainly comprising: a closed space (1)； an air-conditioning device (3) able to keep a constant temperature； an automatic water supply system (4) and multiple movable planting frames (2). Due to the ability of the planting frames (2) to move, the planting frames (2) can move to an aisle of the closed space (1) as required, so that planting areas (11) do not require another aisle to be additionally provided, effectively achieving an increased amount of plants grown while also being able to consider management convenience for personnel. Moreover, with the operation of the constant temperature air-conditioning device (3), the planting areas (11) and an aisle area (12) are constantly maintained within a set range of temperature difference, such that the temperature of the planting areas (11) is perfectly within a suitable environment for plant growth so as to increase the rate of plant growth.
