Key Technical Points and Management Methods for Lettuce Seedling Raising

Lettuce is a common vegetable. What appears on our dining tables is not only the lettuce stem but also the lettuce leaves, both of which are very delicious foods. Before planting lettuce, it is generally necessary to raise seedlings first, so how are lettuce seedlings raised? How can the germination rate of lettuce be improved? How can lettuce seedlings be made to grow better? Below let us learn about lettuce seedling raising techniques together.

1. Seedbed preparation

Now lettuce can be seen on the market all year round, which means that we can now use different cultivation techniques to grow lettuce throughout the year. But with different cultivation techniques, the seedling raising techniques are largely the same. Before sowing, we should choose a suitable seedling raising site and then prepare it. The seedling raising site is generally best close to a water source, with good soil permeability, good drainage, fertile soil, and sufficient sunlight. When preparing the seedbed, we should add sufficient farmyard manure to the soil, then mix the soil and fertilizer evenly, and finally mix in an appropriate amount of phosphate fertilizer and nitrogen fertilizer. Level the seedbed and make drainage ditches, and then it is ready for sowing.

2. Seed treatment

There are now many lettuce varieties, so we should choose a suitable variety according to the location and the planting season. For example, the American Queen and Emperor, Japan's Olympia, and so on are all excellent varieties. If saving seeds yourself, the seeds should be sun-dried before sowing, which can play a sterilizing role. Secondly, if you want to improve the germination rate of the seeds, we can also carry out seed soaking treatment, soaking the seeds in water for four or five hours, and then placing them in a suitable environment for germination. Generally, in two or three days basically all the seeds will show sprouting points, and then they can be sown.

3. Scientific sowing

Before sowing, water the seedbed once, then scatter a layer of fine soil, then evenly scatter the treated lettuce seeds on the seedbed, and finally cover with a layer of fine, slightly moist fine soil to cover the seeds. If the temperature is too low, you can also cover the top with a layer of plastic film, or straw or the like, which can play a role in keeping warm and retaining moisture. Under such conditions, seedlings generally emerge in four or five days, so we should also remove the covering in time so as not to affect the growth of the lettuce seedlings.

4. Seedling stage management

After the lettuce seedlings emerge, we then need to cultivate the growth of the seedlings and improve the resistance of the seedlings as much as possible during the seedling stage. After the seedlings emerge, we first need to clear the weeds in the field, and then water appropriately, but during the seedling stage we generally water by spraying, so that it will not affect the growth of the seedlings. Then, in order to promote the growth of the seedlings and carry out transplanting as early as possible, we can also appropriately apply additional nitrogen fertilizer. Also, for some very weak seedlings, we can appropriately pull some out. Finally, it is necessary to do a good job in preventing and controlling pests and diseases. There are also many pests and diseases during the seedling stage, so field management must not be relaxed.

Lettuce cultivation is generally carried out by the method of raising seedlings and transplanting, so today the editor has only shared with everyone one basic part of lettuce cultivation, namely lettuce seedling raising techniques.
