For those who like to eat small tomatoes, now that the weather is relatively warm, you can start to grow tomatoes at home. The small tomatoes and big tomatoes that the blue demon sprouted a few days ago have already emerged, so let's share with you the planting and management technology of tomatoes, let's plant tomatoes together! The content of this article is a bit long, read it patiently, and help you achieve tomato freedom!

1. How to choose tomato varieties?

There are many varieties of tomatoes, so what varieties should I choose? Here we only need to know 2 points to make a choice easily.

1. Fruit size

Tomatoes are divided into large tomatoes and small tomatoes, large tomatoes are mostly used as vegetables, of course, some varieties are also delicious when eaten raw, and the amount of fruit hanging from large tomatoes will be relatively less, after all, they are large. Small tomatoes, on the other hand, are mostly eaten as fruits, and there are many varieties, some of which are particularly high-yielding. First of all, determine whether you want to plant large tomatoes or small tomatoes, as for the specific variety, you can refer to the variety introduction, or choose the fruit you think is relatively good-looking, good-looking and delicious.

2. Growth limit

Tomato is also divided into limited growth and infinite growth type 2 types, limited growth type of tomato belongs to dwarf varieties, after growing to a certain height, it will no longer grow, it is more suitable for balcony small space planting, of course, the amount of hanging fruit is relatively unlimited growth type of tomato, it is much less.

Infinite growth type of tomato can continue to grow, to put it bluntly, as long as it is not raised, you can always grow fruit, the yield of the infinite growth type of tomato is very high, the fruit-bearing period is also very long, of course, the relative need for growth space will be much larger.

You can choose these two types in combination with your own planting space, the limited growth type with small growth space is preferred, and the limited growth type with large growth space is naturally more attractive.

2. Method of germination and sowing of tomato seeds

It is best for you to buy seeds to sow seeds, which is more cost-effective than buying seedlings, and seedlings, there are not many varieties to choose from, most of them are still the wrong version, and you should choose carefully. Blue Demon recommends that you sow seedlings by yourself, tomatoes are more leathery, and breeding is very simple, so the following will introduce the germination method to you.

Now the temperature in early spring is still relatively low, if the tomato seeds are sown directly, it will take about half a month to germinate, and after germination treatment, the seedlings can generally emerge in a week. The specific germination method is as follows:

1. Immersion

Put the tomato seeds in a disposable cup, pour warm water (the temperature that is not hot in the hand water) and soak for 2 hours, then remove the seeds to dry the surface moisture.

Prepare a wet paper towel or kitchen paper, wash it in clean water, and squeeze out the water, holding the paper towel tightly in your hand to prevent dripping. Then put the seeds on a paper towel, fold the paper towel, wrap the seeds, and put them in a plastic bag to tie the hole, this is mainly to maintain humidity.

2. Keep warm and moisturize

The most important thing in early spring germination is temperature, if there is a continuous heat source at home, it is much more convenient, such as an incubator for hatching chicks, but most people do not have a heat source for continuous heat at home, then you can find a small foam box, and then find a warm water bag, fill the warm water bag with warm water (the hand temperature is not hot), put the warm water bag in the foam box, and then put the seeds in, cover the lid, and then cover the outside of the foam box with a quilt or cotton clothes to reduce heat loss, so that the temperature can be kept at about 10-0 degrees, Lasts about 0 hours.

It is also said that if you put the seeds in the inner pocket of your clothes and carry them closely, you can germinate quickly, and you can also try this method if you are interested.

3. Check the white every day and sow seeds in time

Tomato germination process, to open at least once a day to observe the germination, the seeds should be sown in time, the white seeds continue to be put in the germination box, half a day the big white legs will look very similar, sowing is easier to break.

Therefore, the Blue Demon recommends that you sow seeds in time when you see the seeds exposed, and if you don't have time to plant them for the time being, it is recommended that you take them to the germination box and put them outside, but pay attention to moisturizing. If the temperature is low, the germination rate will be much slower, and it will not have much effect if you take it out in the morning and plant it in the evening.

3. Sowing method of tomato after budding

After the germinated seeds are exposed, they should be sown in time, and there are mainly the following precautions when sowing.

1. The sown soil should be loose and breathable

It is recommended to use the special soil for seedling sowing and seedling, tomato belongs to the more leather, if there is no special soil for seedlings, it is also possible to use loose and breathable general nutrient soil, but try not to use clay and heavy soil for seedlings, easy to compact.

2. The seedling container should not be too large

The container for seedling raising should not be too large, and it is recommended to use a 8 hole tray to raise seedlings, or a disposable cup, and a 0cm nutrient bowl is OK, one hole and one seed, so that it is better to manage and transplant after germination.

3. Avoid bud breakage when sowing

When sowing, the soil should be mixed with water in advance until it is slightly moist, and the soil can be formed into a clump by hand, without dripping, and it is advisable to loosen it and spread it naturally. If the soil is too wet, it is easy to suffocate the seeds, and if the soil is too dry, the seeds will not germinate smoothly.

First fill the soil in the seedling pot about 8 minutes full, and then gently put the germinated seeds on the surface of the soil, pay attention to the horizontal placement on it, the root system will naturally be rooted, the sowing action must be light, don't break the buds, especially the longer buds, you must pay attention to the fact that once the buds are broken, the seeds are useless.

After all the seeds are placed, cover with a thin layer of soil, about 5.0cm thick, and you can not see the tomato seeds.

4. Management before breaking ground after sowing

After the seeds are sown, put the variety label, find a foam box or box, put the seeded seedling pot into the box, and then find a plastic bag to cover it, and put it in a warm place where it can reach the sun, which is more conducive to heat preservation.

Generally, after sowing, on the second or third day, the seeds may break through the soil and emerge seedlings, which depends on the temperature, and before germination, it should be observed once a day.

If you find that the surface soil is dry, you should spray water in time to increase the humidity.

If you find that there are buds that have broken through the soil and emerged seedlings, you should see the sun in time to avoid the seedlings from growing.

4. Tomato seedling management

The temperature is low in early spring, and after the tomato seedlings emerge, it is still necessary to cover the film, but when there is sun during the day, the film should be opened at both ends for ventilation, and the temperature is too high if it is not windproof, and the seedlings will die of heat. A few days ago, Zhejiang soared to 30 degrees, at noon the plastic film covering the seedlings, was blown by the wind and covered again, and when I found out, the tomato seedlings were already hot and almost lying down, fortunately found in time, in time to open the wind, watering, slowly and slowly eased up, so, on a sunny day, pay special attention to the seedlings to wind this medicine.

Another point is that the temperature difference in early spring is large, the temperature is high and low, if you encounter cooling, you should pay attention to heat preservation at night, and you need to cover a layer of film outdoors, or cover an old clothes to keep warm, and it is best to get it indoors.

The management of seedlings is relatively simple, and the focus is on temperature. In terms of watering, it is necessary to properly control, small seedlings should be trained, too much water, do not use the root system to grow, and you can water once when you see that the surface soil is relatively dry.

As the seedlings grow slowly and after the true leaves are grown, the thin potassium dihydrogen phosphate fertilizer can be applied to promote root growth and strengthen the plant. Because tomatoes are easier to grow, nitrogen fertilizer should be used less in the early stage, and the main thing is to nourish roots and strengthen the trunk.
