phenol substance concentration of plant leaves the body of the light beam utilization and Kjeldahl nitrogen concentration control method of.

摘要

PROBLEM TO BE SOLVED: To provide a method for growing plants by individually setting a radiation time of concerning composite rays, while maintaining a concentration of phenol in the leaves of the plants as well as maintaining a concentration of Kjeldahl nitrogen administering nutrient concentration in the plants.;SOLUTION: A method for using light rays that control growing of plants is provided in which, by using devices having composite rays of blue light, green light, yellow light, and red light, the composite rays are radiated to the plants at night or in a darkness individually, separately, or simultaneously so as to let a concentration of phenol increase or decrease in the leaves of the plants as well as let a concentration of Kjeldahl nitrogen increase or decrease.;COPYRIGHT: (C)2014,JPO&INPIT
