The latest planting time and method of lettuce

Lettuce is a common vegetable in our life, its stems and leaves are edible, the stem is fleshy, the taste is crisp and tender, and the market prospect is good. It is cultivated all over our country. So when should I choose to plant it? Let's take a look at the time and method of growing lettuce.

Planting time

Lettuce is adaptable, resistant to half-cold, likes cold environment and is afraid of high temperature, so it can be planted in spring and autumn, and its planting time should be chosen according to the local climate and temperature environment. Spring lettuce is cultivated in the open field from April to May, and autumn lettuce is planted at 9-10, which can survive the winter safely in the Yangtze River basin.

Planting method

1. Soil preparation and fertilization

Lettuce has shallow roots and weak absorptive capacity, so it is better to choose loose sandy soil, choose high-lying, well-drained and dry land, apply sufficient base fertilizer before sowing, then turn deeply, break the soil into pieces, and then flatten and fine. cover with a layer of mulch for planting.

2. Sowing seeds

In order to ensure that the seeds can germinate smoothly, the seeds should be treated before sowing, soak the seeds in clean water for about 6 hours, and then begin to germinate with a wet towel. The seeds of lettuce can be sowed after sprouting, and the seeds of lettuce are relatively small, so when sowing, the fine soil of the environment is stirred evenly and sowed. Before sowing, the soil is watered once, with an average of 2-3 grams per square meter, and a thin layer of fine soil can be covered after sowing. Cover a layer of film after sowing, keep warm and moisturize to speed up budding, observe carefully, when the seedlings are unearthed, lift the film immediately, maintain ventilation and light, and plant when the seedlings grow about 3 true leaves.

3. Planting management

In order to ensure its rapid and strong growth, we should keep the spacing and row spacing 25cm × 30cm, watering in time to promote root development and keep the soil moist. If the planting is a period of high temperature in summer, proper shading should be used to avoid damage to the seedlings. After applying sufficient base fertilizer, there is basically no need to apply fertilizer, you can apply farm light fertilizer once or twice when ploughing or weeding, and pay attention to the shallow root when ploughing, its root system is not developed, and its root system will be damaged if it is ploughed too deep.

The above are the planting time and methods of lettuce brought by pro-agricultural network. Lettuce root system is weak and absorption capacity is low, so in order to grow rapidly, fertilizer and water management should be reapplied. When applying sufficient base fertilizer, there is no need to worry about fertility in the later stage, but the water must be watered frequently, not too much each time, resulting in stagnant water.
