Why the newest tomatoes are not suitable for multiple seedling division

Tomato cultivation is more common, basically every household in rural areas will plant some, and in planting is the need to split seedlings, but tomatoes are not suitable for multiple seedlings, is this the reason? Below, let's take a look at the four reasons why tomatoes are not suitable for many times. Growers had better understand them first.

First, the reason why tomatoes are not suitable for multiple seedlings.

1. it is easy to form aging seedlings.

Tomato seedlings divided too many times, the root system has been unable to expand, the absorption is weak, the seedling growth will be inhibited because of insufficient nutrition supply, once the seedling growth is inhibited for too long, it will form aging seedlings.

2. Easy to hurt the root

If there are too many times of seedling division, the more serious the damage to the root system of the seedling is, and it is very easy to cause the root system of the seedling to age prematurely, and when it is serious, the normal seedling dies, so it is not suitable to divide the seedling for many times.

3. Prolong the nursery period

According to the practical production, it is proved that for each tomato seedling, due to the refining before the seedling division and the slow seedling after planting, the raising time of tomato seedlings of the same size will be extended by 5-8 days, and the extended time will be longer when the environmental conditions are not suitable. Therefore, in order to make the seedling raising time normal, it is not suitable to divide the seedlings for many times.

4. Other injuries

Seedlings are vulnerable to starvation in the process of seedling division, and seedling division during flower bud differentiation will have an adverse effect on flower bud differentiation and directly affect yield and quality.

II. Matters needing attention in dividing tomato seedlings

1. Pay attention to seedling classification

Due to irregular germination before sowing and different sowing depths, the seeds are far and close to the heat source after sowing, and the size of the seedlings is not the same. Therefore, when dividing the seedlings, it is necessary to divide the large seedlings to the south side of the greenhouse and the small seedlings to the north side of the greenhouse. The seedling hole is near the heat source, and the medium seedling is in the middle of the greenhouse.

2. Adjust the planting depth

In order to ensure the consistency of slow seedlings, the planting depth of seedlings should be adjusted when dividing seedlings. Plant deeper near the heat source, slightly past the cotyledon node; shallower away from the heat source, exposing cotyledons; and at a moderate distance from the heat source, the cotyledon nodes of the seedlings should be kept level with the ground.

3. Don't pinch the seedling stem.

The stems of seedlings are tender and easy to cause damage. The correct method of transplanting seedlings is to gently pinch the cotyledons of the seedlings with your hands and put it into the seedling hole.

The above is why tomatoes are not suitable for multiple seedling introduction, hope to help you, want to know more related knowledge, please pay attention to us.
