[0027] A method for lettuce seed germination, comprising the following steps:
[0028] (1) Seed selection and pre-treatment: select lettuce seeds that are plump, free from mildew, moth-eaten, and shriveled, and placed in room temperature and relative humidity of 40-50% to naturally spread out for 6 days, and often turn over when drying the seeds Try to get even and uniform sun exposure, and then dry in the shade at 25°C for 3 days in a dark environment;
[0029] (2) Seed soaking: Soak the above-mentioned pretreated seeds in water at 45°C for 5 minutes by using variable temperature soaking method, then wait for the water temperature to drop to room temperature, and continue soaking at room temperature for 36 hours;
[0030] (3) Disinfection and breaking dormancy: take the above-mentioned soaked seeds, disinfect them with a disinfectant, and then soak them in the soaking solution for 72 hours to break the dormancy state of the seeds;

Embodiment 2
[0042] A method for raising lettuce seedlings. The lettuce seeds are germinated by adopting the above-mentioned method for germination of lettuce seeds, and then the germinated lettuce seeds are moved to an outdoor greenhouse, and the seedlings are kept ventilated and at a temperature ≥ 10°C. The seedlings grow to 5 After -6cm, transplant the seedlings into the predetermined seedling bag for cultivation, and pour the nutrient solution according to the predetermined requirements, and cultivate until the seedlings emerge from the nursery.
[0043] Wherein, the shading degree of the greenhouse is 70-80%, and the height is 1.8-2.0 meters; after the seedlings are transplanted into the predetermined seedling bags for cultivation, the nutrient solution is poured every 8-12 days until the seedlings come out of the nursery, and the Gradually open the shading net of the shade shed one month before going out of the nursery to harden the seedlings.
[0044] Wherein, the nutrient solution ...
