RAISING SEEDLING DEVICE FOR ROOTING GRAFTING YOUNG TREES USING LED LIGHT SOURCE

摘要

The present invention relates to a seedling culturing device for rooting grafts using an LED light source, more specifically to: a seedling culturing device for rooting grafts using an LED light source: which uses the LED light source with easy control of wavelength and output as a light source for emitting light to grafts on a seedling tray mounted on a shelf; forms mixed light by assembling LED light sources in blue wavelength range and LED light sources in red wavelength range; removes phenomena of adventitious roots and colukua by specifically limiting the wavelength, mixture ratio, output, photosynthetic photon flux density (PPFD), etc. of the LED light source; is not influenced by a high temperature, external environment, and seasons; and is capable of producing healthy seedlings by improving the graft rootage rate and growth uniformity of plants. The seedling culturing device for rooting grafts using the LED light source comprises the following: the shelf for storing the seedling tray in which the grafts are mounted; and the light source emitting light toward the seedling tray stored on the shelf. The light source includes multiple first LED light sources emitting light in the wavelength of 640-670 nm and multiple second LED light sources emitting light in the wavelength of 430-460 nm for forming mixed light, in which the first LED light sources and the second LED light sources are formed in a combination ratio of 1.5-2:1.
