How to prevent the lack of onion seedlings

No one wants to see a lack of seedlings when growing onions, but this is a common situation, so what are the ways to prevent this situation? Let's learn how to prevent onions from missing seedlings.

1. Land management

The first thing to do is land management, because many onion seedlings are easy to root and sprout because of these factors. This process mainly covers several aspects, such as sterilizing the land, leveling the land, raising the soil, and so on. Sterilization treatment is to eliminate some substances hidden in the soil, such as weed germs, to avoid harming the seedlings, and then plough the land into suitable plants. finally, in the appropriate fertilization and watering, the soil is more fertile, so that the factors leading to lack of seedlings in the soil will be reduced to the greatest extent.

2. Rational planting

The reasonable planting here refers to the situation that the planting depth and other aspects are up to the standard when planting, so as to avoid the seedling death caused by planting too deep or too shallow. It is better to plant onion seedlings at a depth of about 3 cm. Close the soil first to ensure that the closed soil is loose without clods. Then press the soil down some, so that the soil can be fully wrapped around the onion seedlings, so that it is not easy for the seedlings to be unable to contact the soil, which can effectively prevent the lack of seedlings.

3. Heat preservation and moisturizing

The climate is beyond everyone's control. The weather may be fine when planting, and the weather may continue to change later. In order to prevent the lack of seedlings caused by the weather, we have to do a good job of heat preservation and moisturization. If the temperature is relatively low, then it is best to use plastic film for heat preservation, especially in the open air. Secondly, if the soil is relatively dry, it can be watered after plastic film mulching, which can effectively reduce the volatilization of water and ensure the water demand of onion seedlings.

4. Reasonable elimination

There is no guarantee that the seeds of onion seedlings planted by ourselves are good, and there is no guarantee that they will grow out of good quality, but we can screen them and replace these shoddy seedlings with high-quality ones. Reasonable elimination of some substandard seedlings can effectively reduce the harm of these weak seedlings to the surrounding. Secondly, we can continue to plant new seedlings on the basis of these young goose eggs and reduce the lack of seedlings. Like some diseased seedlings, dwarf seedlings and so on are generally the primary targets for elimination, because this has a certain degree of diffusion.

These are some of the ways to prevent and cure the lack of seedlings when planting onions. If you encounter it, you should first understand what causes it, and then solve it pertinently, so that it is not easy to follow up.
