The present application relates to the technical field of sapling cultivation, in particular to a seedling anti-freezing device for forest cultivation, which comprises a base and a water inlet, the base is hollow and has a water storage function, the outer wall of the base is made of rubber plastic material and has a heat preservation effect, at least two heat exchange mechanisms are installed on the upper surface of the base at equal intervals in the circumferential direction, the heat exchange mechanisms extract water from the air to supplement the saplings, a supporting mechanism is installed between the heat exchange mechanisms, the bottom of the supporting mechanism is fixed to the base, the supporting mechanism supports the plastic cloth and prevents the saplings from freezing. The device effectively breaks the low-temperature-induced dormancy mechanism of the sapling root system, prevents the sapling rhizome from freezing injury and death, provides a suitable temperature environment for root development, effectively avoids soil water evaporation, continuously ensures soil moisture, promotes the growth and development of the sapling root system, and thus shortens the tree maturation period. The device can increase the light concentration to increase the temperature and avoid low temperature from inhibiting the growth of the saplings, or can reduce the light concentration to reduce the temperature and prevent high temperature from burning the saplings.
