How to grow lettuce with a high germination rate? How to manage the seedlings?

Lettuce is a very common vegetable in daily life, and the demand in the catering market is very large, as if no matter in **, lettuce is indispensable for eating, whether it is a hot pot restaurant, a barbecue restaurant or a home-cooked dish is essential. Therefore, if growers go to plant lettuce, the economic benefits are also good, but many people will not have a high germination rate when planting lettuce. If you want to improve the germination rate of lettuce, you must first choose a better variety, and then find a way to urge, after the sprout lettuce seedlings grow, remember to water frequently, and pay attention to the prevention and control of pests and diseases.

Now a lot of lettuce is actually grown in the greenhouse, if in terms of time, lettuce is most suitable for germination in spring and autumn, the temperature at this time is more suitable, the temperature required for the germination of lettuce is about 15 22 degrees. If the temperature exceeds 30 degrees Celsius in summer, lettuce is prone to non-germination. Therefore, if the average grower grows lettuce, it is best to sow it in October, which can improve the seedling emergence rate.

And if you want to improve the germination rate of lettuce, you must soak and germinate, so as to ensure that all lettuce seedlings emerge. Before choosing lettuce seeds, be sure to choose those particles that are relatively full, and the size of the seeds should be more symmetrical, first put the seeds in a clear water to soak for about three or four hours, the amount of water can be slightly more, 1 2 cm higher than the seeds. The germination of any kind of seeds is inseparable from water, and after these seeds have fully absorbed the water, they can be fished out and dried, and then wait for germination.

Lettuce is actually different from other vegetables, and it can also germinate in a low temperature environment, so you can first put the seeds in a bag, and then put them in the refrigerator to refrigerate, the approximate temperature is about 5 10 degrees, and it can also germinate. During the period of lettuce germination, remember to take it out and wash it with water once a day, and then continue to germinate. After 4 to 5 days of repeating this, the seeds will germinate, and then they can be taken to the ground to be planted.

After planting, it is necessary to ensure water and nutrients, so as to improve the germination rate. In the process of management, it is necessary to manage the water bill, so that they can help germinate and increase the yield.

When planting lettuce, it is necessary to plant it shallowly, and to apply a layer of mulch, so that the germination rate will be relatively high.

You can plant seeds directly, pay attention to keeping warm, lay a layer of film, and regularly manage water and fertilizer, so that you can grow better.

1. First of all, the seeding bed should be set up in a ventilated and cool place as much as possible, and black shade nets should be used for shading to reduce air temperature and ground temperature.

2. Secondly, lettuce varieties that are resistant to high temperature and pumping should be selected, and treated at low temperature.

3. Soak the lettuce seeds in cold water for 30 minutes, drain the water, put them in a sealed plastic bag, put them in the cold room of the box (about 2 3), and take them out after 2 days to sow seeds.

4. The lettuce seeds treated in this method have a neat germination rate and germination, and all seedlings can emerge 1 or 2 days after sowing.

5. Lettuce seeds need light when germinating, and germination under the dark is inhibited, which is a major feature of lettuce seed germination, and it is important to avoid sowing too deeply. Good seeds germinate 3 days after sowing at the right temperature.

Soak the prepared seeds in water for about 6 hours, then take out the seeds after scrubbing, wrap them in moist gauze and place them in a container, and put them in an environment of about 20 degrees Celsius to germinate, pay attention to keep the gauze moist, and when 80% of the seeds have been exposed, you can sow them.

Choose fertile and loose soil, sprinkle lettuce seeds evenly on top of the soil, then cover the seeds with a thin layer of soil, place them in a warm place to maintain, they will germinate in about 3 to 4 days, and when it grows 2 to 3 leaves, it is necessary to divide or intersect seedlings in time.
