Key points of Tomato cultivation techniques

There are four key points in tomato cultivation techniques. The first point is to sow and raise seedlings, make a good substrate before sowing and disinfect the seeds to promote germination, and cover with a thick substrate of 0.5cm after sowing. The second point is the seedling stage management, after emergence to control the temperature, water and nutrition. The third point is planting, transplanting the seedlings into the field in early September and watering the fixed value water. The fourth point is field management, which can do a good job in water and fertilizer, leaf picking, pest control and so on.

High-yield cultivation techniques of tomato:

1. Select improved varieties

A good variety is the basis of high yield. at present, there are a wide variety of tomatoes on the market, and there are many varieties, but you will find that different varieties of tomatoes have different tastes, some taste much better, and some look good. There are a variety of problems, such as poor taste, because different varieties have different effects in different areas. Therefore, we generally select seeds according to the specific conditions of the location. for example, in Hunan, we can choose varieties with strong drought resistance and disease resistance.

2. Sowing seeds at the right time

Sowing at the right time is also an important condition for high yield. because there are many varieties of tomatoes and there are some differences in climate in different parts of our country, the planting time of different varieties and different regions is different. for example, in the northeast and northwest of China, tomatoes can be planted for two seasons, and they can be sown in March and June every year. In North China, sowing begins in January and February every year, but tomatoes are basically planted in March and August every year, so you can see which region of our country you are in. Then sow seeds according to the scientific time.

3. Reasonable density

Basically, the yields of crops, fruits and medicinal materials are more or less related to the planting density, so tomatoes are the same. we have to carry out density management according to the variety selected and the fertility of the planting land. under normal circumstances, one mu of land can generally plant about 500 to 600 plants, but when the seeds are suddenly barren, we can increase the number of plants appropriately. On the other hand, the quantity is reduced under the condition of abundant soil fertility. The distance between each row is generally between 40 to 50 centimeters, and the distance between each plant is about 30 to 40 centimeters, so that the chicken facilitates later field management, and at the same time, tomato plants also have some room to stretch to facilitate photosynthesis.

4. Scientific fertilization

In addition to the base fertilizer, tomatoes need to be fertilized many times throughout the growing period. the first time is after planting. This fertilization can be carried out by using urea to promote seedlings, and when the tomato blossoms, we have to apply the second fertilizer. This time we can use potash and phosphate fertilizer, which can have an effect of promoting flowering and fruit protection. The third fertilization is, of course, when the tomato fruit expands after setting fruit. At this time, we can be divided into multiple fertilizers, because tomatoes can be harvested in batches, so we can spray a little foliar fertilizer after each harvest, which can achieve the effect of strong fruit and promote fruit ripening.

5. Pruning and pruning

Tomatoes grow a lot of side branches in the process of growth, and many people will think that more side branches means a higher rate of fruit. in fact, this is not the case. if there are too many side branches, the more nutrients they consume, although there are a lot of tomatoes, in the end, there are basically few high-quality tomatoes, so we usually prune all the extra branches and leaves, and then keep only the trunk and part of the side branches. Then the denser leaves will be removed in the fruiting place, so that the plant can better absorb nutrients and photosynthesis, at the same time, the field permeability is also better, which can also prevent a lot of diseases.

The above is the introduction of tomato cultivation techniques. I hope it will be helpful to you.
