NURSERY DEVICE FOR ROOTING GRAFTED SEEDLINGS USING LED LIGHT SOURCES

摘要

The present invention relates to a seedling device for taking roots of grafts using LED light sources. More specifically, provided is a seedling device for taking roots of grafts using LED light sources, which removes adventitious root and suberization of grafts when raising seedlings, is not influenced by external environment such as high temperature and seasons, improves a root taking rate of grafts of plants and growth uniformity, and produces healthy seedlings by selecting LED light sources which can easily control wavelength and output by light sources irradiated to the grafts of a seedling tray equipped on a truck for seedlings, forming mixed light by combining a plurality of LED light sources in red and blue wavelength bands, and specifically limiting wavelength of the LED light source and photosynthetic photon magnetic flux density (PPFD), etc.
