The invention belongs to the technical field of hydroponic cultivation and soilless cultivation of plant factories, and discloses a method for measuring hydroponic cultivation of ice-leaf day flowers and a method for measuring the ratio of LED light quality, namely red light: blue light: ultraviolet light=20:5: 1; Install 3 tubes, the light intensity is 300μmol/(m 2 ·s), the period is 14h/d, and the indoor temperature is 20-22°C. The experiment was repeated 3 times, each time setting 7 kinds of light quality, red light, blue light, red light: blue light = 4:1, red light: blue light = 8:1, red light: blue light: green light = 4:1: 1, red light: blue light: ultraviolet light = 20: 5: 1, white light control; wherein the wavelength of red light is (660 ± 10) nm, the wavelength of blue light is (450 ± 10) nm, the wavelength of green light is (520 The wavelength of ±10) nm and ultraviolet light is (300±10) nm. The 18W white fluorescent lamp was selected as the light source. |
