1, choose suitable soil, lettuce grows fast, leaves are fresh and tender, and fertile soil is needed. Choose soil with rich organic matter and good air permeability. In order to make lettuce grow better, it is best to apply fully decomposed farm manure and organic fertilizer in the soil and plant it at home. If farmyard manure and organic fertilizer are sufficient, lettuce can still grow healthily without applying chemical fertilizer.
2. Choose seeds for sowing, choose healthy and full lettuce seeds, soak them in warm water for about 10 hour before sowing, take them out and put them in an environment of 20 degrees for germination. When the seeds turn white, they can be sown. The soil moisture content of lettuce cultivation is about 90%. Sprinkle lettuce seeds evenly on it, cover it with a thin layer of moist soil, and then cover it with plastic film to keep the soil moist.
3, seedling management, lettuce seedlings, still keep the soil moist, found that drought water in time, but the amount of water should not be too large, to prevent excessive water from causing diseases and affecting root respiration.
Ensuring sufficient sunshine is more conducive to the growth of lettuce.
4. spawn in time. Lettuce seeds are small and easy to be dense when sowing. After emergence, the over-dense lettuce seedlings should be removed, and the removed seedlings can be transplanted. First, the spacing between plants should be kept at 2 cm, and then further spacing should be carried out with the growth of seedlings. When lettuce grows to more than 5 leaves, it can be transplanted. Choose high quality and strong seedlings.
Lettuce seedlings can be transplanted with equal row spacing of 20 cm, row spacing of 20 cm or row spacing of 20×25 cm.
