Sprouting methods of lettuce, lettuce, etc.

Lettuce, lettuce and wheat lettuce are cultivated species of 1-2-year-old herbs of the genus Lactuca of Compositae. Originated from the Mediterranean coast of western Asia, it is a cold-resistant, cool and heat-resistant vegetable. Seeds can begin to germinate at 4 ℃, and the suitable germination temperature is 15-20 ℃. When the temperature is higher than 25 ℃, it is difficult to germinate due to water absorption of seed coat. Therefore, in summer and autumn cultivation, because the sowing time is still in the summer high temperature stage, the seed germination is often poor. The method of accelerating germination and sowing can be adopted, and it is proved by practice that the following methods have a good effect on seed germination.

The seeds are wrapped with fine gauze or bean-wrapped cloth (because the seeds are small to prevent leakage), and the seed cloth should be slightly larger according to the seed volume, so as to facilitate the seed cleaning process. Put the wrapped seeds in clean cold water and gently scrub them with your hands several times to make the seeds fresh and clean, then soak the seeds in cold water for 2-3 hours, remove and drain the excess water, wrap them with wet towels and put them into the refrigerator freezer (5-10 ℃) for 24-36 hours, remove and wash the seeds and towels, wrap them with wet towels and place them at room temperature (about 20 degrees Celsius) to accelerate germination, usually a large number of seeds can be exposed after 1-2 days.

Pay attention to the germination process, all supplies can not be touched with oil, hands can not take oil, let the seeds breathe. The function of wet towel is moisturizing, too dry does not play a moisturizing role, too wet affects seed respiration, which is not conducive to seed germination, so it is suitable for water to flow out when holding hands hard.
