PLANT ILLUMINATION AND CULTIVATION METHOD HAVING INSECT PROOFING EFFECT, AND ILLUMINATION APPARATUS FOR PLANT CULTIVATION

摘要

THE PRESENT INVENTION PROVIDES A PLANT ILLUMINATION AND CULTIVATION METHOD, THAT IS A CULTIVATION METHOD OF ILLUMINATING PLANTS IN A LIGHT OR LIGHTLESS ENVIRONMENT, WHEREIN REGARDING THE ILLUMINATION, EMITTED LIGHT HAS AN EMISSION PEAK WAVELENGTH IN THE GREEN TO RED REGION, AND FLASHES WITH A PREDETERMINED FLASHING PATTERN OF A LIGHT PERIOD DURATION AND A DARK PERIOD DURATION, AND REGARDING THE FLASHING, A DUTY REPRESENTED BY THE FOLLOWING FORMULA (1) IS 50% OR LESS: DUTY (%) = LIGHT PERIOD DURATION/(LIGHT PERIOD DURATION + DARK PERIOD DURATION) X 100 (1). ACCORDING TO THE PRESENT INVENTION, IT IS POSSIBLE TO PROVIDE A CULTIVATION METHOD THAT HAS AN INSECT PROOFING EFFECT SUCH AS A MOTH PROOFING EFFECT WHILE CONTROLLING FLOWERING INHIBITION OF SHORT-DAY PLANTS SUCH AS CHRYSANTHEMUM.
