Taking hot pepper as material，effect of the far-infrared heating film radiation on winter-spring hot pepper seedling was studied in the the greenhouse low temperature stress conditions.The results showed that the treatments of far-infrared heating film radiation promoted germination potential and germination rate significantly.Increased photosynthesis and root activity of the treatments resulted in more plant growth and root system development significantly，which helped to cultivate strong seedling.Compared with direct heating，the effects of heating with 2 cm earth covered on the far-infrared heating film radiation were better.As a result，the treatment of far-infrared heating film radiation can reduce 15 days of seedling age in hot pepper and produce remarkable economic，ecological and social benefits.
