Electric heating films have been successfully applied for heating in agricultural vegetable greenhouses, greenhouse seedling breeding, and other scenarios. They have been utilized in multiple fields, both domestically and internationally, as electric heating elements with outstanding characteristics.
In the greenhouse shed, the area without electric heating films only reaches 18°C, while the contrast within the shed is striking: the soil temperature in the region with electric heating films can reach 28°C. The root development of crops in the electric heating film area is significantly better than that in the control group, and the above-ground growth is also more vigorous.
With flexible control, electric heating film heating allows for convenient temperature adjustment, eliminating the need for personnel to manually adjust it at night. The temperature of electric heating film heating can be freely adjusted, preventing economic losses caused by freezing of greenhouse seedlings due to sudden drops in outdoor temperature, and achieving the effect of rapid temperature increase and decrease.
Crops have developed root systems when using electric heating film heating, and they can be directly transferred to outdoor environments. Compared with coal heating, seedlings harvested in the same period using electric heating film heating can be marketed 10-15 days earlier, shortening the maturation period and increasing agricultural output.
