Seedling raising techniques of lettuce

Lettuce is a common vegetable, not only lettuce, but also lettuce leaves appear on our table, which are very delicious food. Before planting lettuce, it is generally necessary to raise seedlings first, so how do lettuce grow seedlings? How can we improve the emergence rate of lettuce? How can we make lettuce seedlings grow better? Now let's learn the seedling technique of lettuce.

1. Seedbed preparation

Now lettuce can be seen on the market all the year round, that is to say, we can use different planting techniques to grow lettuce throughout the year. But with different planting techniques, its seedling raising techniques are generally the same. Before sowing, we should choose a suitable breeding site, and then sort it out. Generally speaking, the seedling land should be close to the water source, the soil permeability is good, the drainage is good, the soil is fertile and the light is sufficient. When making the seedbed, we should add enough farm manure to the soil, then mix the soil and fertilizer evenly, and finally mix the right amount of phosphorus and nitrogen fertilizer, flatten the seedbed, set up a good ditch, and wait for sowing.

2. Seed treatment

There are many varieties of lettuce now, so we have to choose the right one according to the location and planting season. For example, queens and emperors of the United States, Olympia of Japan, and so on, these are excellent varieties. If you keep your own seeds, you should dry them before sowing, which can play a role in sterilization. Secondly, if we want to improve the budding rate of seeds, we can also soak the seeds in water for four or five hours, and then put them in a suitable environment for sprouting. Generally, the seeds will show budding points in two or three days, and then we can sow seeds.

3. Scientific sowing

Water the seedling bed before sowing, then sprinkle a layer of fine soil, then spread the treated lettuce seeds evenly on the seedbed, and finally cover the seeds with a thin layer of fine soil with a little humidity to cover the seeds. If the temperature is too low, you can also cover the top with a layer of plastic film, or straw and the like, which can play a role in heat preservation and moisturizing. Under such circumstances, seedlings usually emerge in four or five days, so we have to remove the cover in time so as not to affect the growth of lettuce seedlings.

4. Seedling stage management

After the emergence of lettuce seedlings, then we need to cultivate the growth of seedlings and improve the resistance of seedlings as much as possible in the seedling stage. After emergence, we first need to clean up the weeds in the field, and then water them properly, but the watering at the seedling stage is usually carried out by spraying, so that the growth of the seedlings will not be affected. Then in order to promote the growth of seedlings, transplant as soon as possible, then we can also apply nitrogen fertilizer properly. In addition, for some very thin seedlings, we can pull out some properly. Finally, it is necessary to do a good job in the prevention and control of diseases and insect pests, there are also a lot of diseases and insect pests during the seedling period, so field management can not be relaxed.

Lettuce is generally planted by seedling transplanting, so today the editor only shares with you one of the bases of lettuce planting, that is, the seedling technology of lettuce. If you want to learn how to grow lettuce, or if you want to know more about planting, you can follow us.
