Lettuce, lettuce, and oiled wheat are cultivars of 1-2 year-old herbaceous plants of the genus Compositae. Native to western Mediterranean coasts of Asia, it is a cold-tolerant, hi-cool, and heat-tolerant vegetable. The seeds can start to germinate at 4°C, and the suitable germination temperature is 15-20°C. When the temperature is higher than 25°C, germination is difficult because of seed coat water absorption difficulties. Therefore, in the summer and autumn, the seeding period is still in the high temperature stage in summer, and the seeds are often sprouted and emerged poorly. The method of germination and sowing can be adopted, and it has been proved by practice that the following method has a good germination effect.
Seeds are wrapped with fine gauze or bean hull cloth. According to the seed amount, the cloth is slightly larger to facilitate the germination process to clean the seeds. Put the wrapped seeds in clean cold water and gently scrub them several times to make the seeds fresh and clean. Then soak them in cool water for 2-3 hours, remove and drain the excess water, and wrap them in a wet towel and put them in the refrigerator freezer ( 5-10 °C) treatment 24-36 hours, take out the cleaned seeds and towels, packaged with a wet towel at room temperature (about 20 degrees) germination, generally after the first 1-2 days the seeds can be exposed in large quantities.
Note that all the supplies of the germination process cannot be oiled, and the hand cannot carry oil, allowing the seeds to breathe and breathe. The role of the wet towel is to moisturize, too dry will not achieve the moisturizing effect, and the wetness will affect the seed breathing, which is not conducive to the germination of the seed.
