How to grow lettuce

Lettuce is a kind of lettuce that we come into contact with every day. Eating raw and stir-fried is a good choice. It has a broad market in our country. But growing lettuce is not as simple as farmers think. It takes a lot of energy to grow good lettuce. Let's learn how to grow lettuce with the editor.

1. How to breed

Lettuce seeds should be soaked in water for 4-5 hours before planting. Do not plant lettuce directly after soaking. Put lettuce seeds in a wetter environment so that lettuce seeds come into full contact with air to speed up germination. Wait until there are signs of rupture on the surface or a day or so can be put into the nursery. The thickness of the soil layer in the nursery can be controlled at 5-10 cm. It is best to mix some fine sand in the soil to enhance the air permeability of the soil. Cover the soil layer on the surface of the seed no more than 1 cm, generally can cover the seed, so that it can have full contact with the soil.

2. Colonization treatment

After emergence, the number of young leaves should be observed, and when most of the seedlings in the nursery have 3-4 young leaves, they can begin to transplant. When moving seedlings, try to make sure that there is soil on the young roots of lettuce, and if not, transplant immediately, so if the seedlings are far away, try to transplant the surrounding soil where the seedlings grow. Apply a little fertilizer to the planting point, and then cover the rhizome with the surrounding soil. Don't squeeze it hard, just squeeze it a little bit.

3. Planting management

The week after planting needs to be paid more attention to, which can tell whether the transplanted seedlings can survive. If the general growth of seedlings is not ideal, then it is very likely that there is a lack of fertilizer. Lettuce is more prone to diseases and insect pests, so once it is found that there is a tendency to disease or insect pests, it should be dealt with in time. If the disease is not serious at the initial stage, you can try to remove the location of the disease, if there are still such diseases, it is best to control them, and the same is true of pests.

4. Fertilizer and water

Fertilizer and water is the most important part of lettuce growth, because lettuce grows very fast, so fertilizer and water should be applied more frequently. Watering begins about a week after planting, and the later watering is controlled at about 7-10 days. According to local conditions, the number of times can be reduced when the soil is moist, and the times can be increased appropriately if it is drier, which is judged by the degree of soil drought. Organic fertilizer is recommended in the initial stage of planting, and compound fertilizer can be used if it is not available. Generally, it will be mainly potash fertilizer, because lettuce is mainly long leaves, the proportion of nitrogen, phosphorus and potassium is controlled at about 1:1:3, the amount per mu is controlled at about 40 jin, and those with poor soil fertility can be applied a little more.

These are some of the techniques for growing lettuce. I don't know how farmers know how to grow lettuce now. Want to know some questions about other aspects of lettuce, you can come to the website to inquire, more information that we do not know and other farmers to explore.
