The fan (4) provides the wind speed of 0.4-1.0 m/s, so that the heat (heat in the surrounding environment of the power supply (1) or the growth chamber) emitted by the LED lamp can be timely emitted to the surrounding environment of the growth chamber. Meanwhile, the fan (4) can update the atmosphere in the growth chamber in real time to maintain proper temperature, humidity and carbon dioxide concentration (the temperature is 23-25 ℃, the humidity is 60-90% and the carbon dioxide concentration is-500 ppm).
Through the gas sampling port (16) above the LED light source, a gas sample can be collected to carry out gas composition analysis, and the photosynthetic rate of vegetables in a certain period of time can be measured by connecting a carbon dioxide instrument, so that the growth condition of the vegetables can be judged.

On day 7, thinning to 1 plant/cultivation cup, continuing to cultivate, adjusting light intensity to 200 μmol/m2And s. On day 15 to day 35, the light intensity was adjusted to 300. mu. mol/m2/s。
During the period, the moisture content of the substrate is measured by a three-parameter sensor (9), and moisture is added from a water injection port (15), and the moisture content of the substrate is maintained within the range of 30-35% (volume ratio). The water was added 7 times in total, and 10148ml of water was consumed. During the period, the vertical rod (6) and the telescopic cover (7) are adjusted for 6 times according to the height of the plant, and the distance between the LED lamp panel (5) and the cultivation cup (10) is kept for 5cm all the time.
Fourth, on day 35, lettuce ripened and harvested. The average fresh weight of each lettuce plant is calculated to be 48.81 g/plant, the production efficiency per unit area is 139.45 g/square meter/day, and 585.70 g (12 lettuce plants) are harvested together in the whole cultivation disc (8). On day 34, the photosynthetic rate of the plants was measured to 9.77. mu. mol CO by connecting a carbon dioxide analyzer through a gas measuring port (16)2/m2/s。
