Lettuce seed germination
To simply accelerate the germination of lettuce seeds, it is necessary to soak the seeds in clear water for 6-7 hours to make the seeds absorb enough water, and then put the seeds in a wet cloth and put them in an environment of 20-25℃. During this period, the seeds are washed once a day, and it takes about 3-4 days for the seeds to germinate quickly.
How long does it take for seeds to germinate?
Generally, lettuce seeds can germinate about 10 days after sowing, because lettuce seeds are not as easy to germinate as other vegetables, so it is best to germinate first, then sow, and soak in warm water first.
Direct sowing
Lettuce seeds can be sown directly, which can generally reduce the complicated procedures of transplanting, reduce the slow seedling stage of lettuce caused by transplanting, appropriately shorten the planting cycle of lettuce and harvest it in advance.
Seed collection
In order to collect lettuce seeds, it is usually to wait for lettuce to mature and let it continue to grow. When it grows higher and higher, the seeds will mature in autumn, and then the parts with seeds will be collected and planted in the next spring.
Germination process of lettuce seeds
Lettuce seeds should provide a growing environment of 15-20 degrees after sowing. When the temperature exceeds 25 degrees, the water absorption of seed coat is blocked, the germination time is delayed, and the germination is poor. If the temperature is normal, it will take about 10 days to germinate.
Lettuce seed planting
Sowing: You need to choose loose and fertile soil for sowing, mix the seeds into a pot, and then gently cover the seeds with a thin layer of soil. After putting it into the pot soil, it needs to be watered and moisturized.
Maintenance: Lettuce germinates in a short time, usually in 3-5 days. When curing, you need to water immediately to keep the soil moist, but you can't accumulate water. When the seedlings grow 5-6 true leaves, they can be transplanted.
