Example Embodiment
[0042] Example 1
[0043] Select tomato seeds with the same size and full grains (purchased from Xinjiang Shihezi Vegetable Research Institute), disinfect them with 3% sodium hypochlorite for 15 minutes, and then rinse them with distilled water until they are tasteless. Then place the tomato seeds evenly on a tray containing vermiculite, and sprinkle a thin layer of vermiculite on the surface of the seeds to prevent light from germinating, add appropriate moisture to the bottom of the tray and seal the plug with plastic wrap. Cultivate in an artificial culture room until germination, tear off the fresh-keeping film, and when it grows to two leaves and one heart period, transfer the tomatoes to a hydroponic tank containing 1 / 2 of the Hoagland nutrient solution, and place them in the automatic control growth room ( 15-17 hours of light, 7-9 hours of darkness, relative humidity of 55%-65%, temperature of 24℃~28℃ in daytime, 18℃~22℃ at night). After three weeks of hydroponics, selec...
