Lettuce planting time and method
Lettuce is a common vegetable in our life. Its stems and leaves are edible, the stems are fleshy, the taste is crisp and tender, and the market prospect is good. It is cultivated everywhere in China. So when should I choose to plant it? Let’s take a look at the timing and method of planting lettuce.
Planting time Lettuce has strong adaptability, is resistant to semi-cold, likes cold environment, and is afraid of high temperature, so it can be planted in spring and autumn. Its planting time is also selected according to the local climate temperature environment. The spring lettuce cultivation time is from April to May, and the autumn lettuce is planted in 9-10, which can be safely wintered in the Yangtze River.
Planting method 1, soil preparation and fertilization
The roots of lettuce are shallow and the absorption capacity is weak. Therefore, it is better to choose loose sandy soil. Choose a land with high topography, good drainage and dryness. Apply enough base fertilizer before planting, then deep turn and knock the soil out. Crush, then level and smooth, cover with a layer of cover to prepare for planting.
2, sowing
In order to ensure the smooth germination of the seeds, the seeds should be treated before sowing, and the seeds should be placed in water for about 6 hours, then wrapped in a wet towel to start germination. After germination, the seeds of lettuce can be sown. The seeds of lettuce are relatively small. Therefore, the soil in the environment is evenly stirred and then spread. The soil is irrigated once before planting. The average seeding is 2-3 grams per square meter. After sowing, it is covered with a shallow layer. Fine soil can be. After sowing, cover a layer of film, keep warm and moisturize to accelerate sprouting, carefully observe, when the seedlings are unearthed, immediately open the film, keep ventilation and light, and wait until the seedling grows about 3 pieces of true leaves.
3. Colonization management
In order to ensure its rapid growth and growth during planting, the spacing and spacing should be kept 25cm×30cm, watering should be carried out in time to promote the development of root system and keep the soil moist. If the planting is in the high temperature period in summer, appropriate sunshade should be taken to avoid damage to the seedlings. After applying the base fertilizer, there is basically no need to apply fertilizer. It can be combined with one or two farmer's light fertilizers when cultivating or weeding. It is also necessary to pay attention to the shallow root when cultivating. The root system is not developed, and the cultivating is too deep, which will damage it. Root system.
The above is the planting time and method of lettuce. The root system of lettuce is weak and the absorption capacity is low. Therefore, if it is fast growing, the management of fertilizer and water should be re-applied. When applying the base fertilizer, there is no need to worry about fertility in the later stage, but the water must be poured. Every time, it should not be too much, causing water accumulation.
