A Full Analysis of the Key Points of Tomato Cultivation Techniques

There are four key points in tomato cultivation techniques. The first point is sowing and seedling raising: before sowing, the substrate must be prepared and the seeds must be disinfected and sprouted, and after sowing, cover with 0.5cm of substrate. The second point is seedling-stage management: after emergence, control temperature, water and nutrients well. The third point is planting out: in early September, transplant the seedlings into the open field and water them in well after planting. The fourth point is field management: do a good job with water and fertilizer, leaf pruning, and pest and disease control.

High-yield tomato cultivation techniques:

1. Choose good varieties

A superior variety is the foundation of high yield. The tomatoes on the market today are dazzlingly varied, with a great many varieties, but you will find that different varieties of tomatoes taste different. Some are much tastier, while some look good but taste poor, and there are all kinds of other problems. That is because different varieties produce different results when grown in different regions, so we generally select seeds according to the specific local conditions. For example, in the Hunan region, you can choose varieties with stronger drought resistance and disease resistance.

2. Sow at the right time

Sowing at the right time is also an important condition for high yield. Because there are now quite a lot of tomato varieties, and the climates across our country differ to some extent, different varieties and different regions have different planting times. For example, in the Northeast and Northwest regions of our country, tomatoes can be grown in two seasons, and sowing can be done in March and June each year, while in the North China region of our country, sowing begins in January and February each year. But in general regions, tomatoes are basically planted in March and August each year, so you can see which region of our country you are in and then sow according to the scientific time.

3. Reasonable density

Basically, the yield of crops, fruits, medicinal herbs and so on is more or less related to planting density, so tomatoes are the same. We should manage density according to the variety chosen and the fertility of the planting site. Under normal circumstances, one mu of land can generally plant a little over five hundred to six hundred plants, but when the soil is relatively poor, we can appropriately increase the number planted, while under conditions of relatively abundant soil fertility, reduce the number. The distance between rows is generally between forty and fifty cm, and the distance between plants is about thirty to forty cm. This makes later field management convenient, and at the same time the tomato plants also have a certain space to spread out, which is convenient for photosynthesis.

4. Scientific fertilization

In addition to the base fertilizer, tomatoes also need multiple rounds of fertilization throughout the growing period. The first is after planting out, when fertilization is needed; this fertilization can use urea to promote seedling growth. When the tomatoes flower, we need to carry out the second fertilization; this time we can use potassium fertilizer and phosphorus fertilizer, which can promote flowering and help retain fruit. The third fertilization is, of course, when the tomatoes swell after fruit set. At this time we can apply fertilizer in several rounds, because tomatoes can be harvested in batches, so after each harvest we can appropriately spray a little foliar fertilizer, which can achieve the effect of strengthening the fruit and at the same time promote fruit ripening.

5. Pruning branches and leaves

During the growth process, tomatoes will grow a great many side branches. Many people think that more side branches means a higher fruiting rate, but that is actually not the case. If there are too many side branches, then the nutrients consumed are greater. Although many tomatoes are set, in the end there are basically very few high-quality tomatoes. So we generally prune away all the excess branches and leaves, then keep only the main stem and some side branches, and then at the fruiting sites also remove the relatively densely growing leaves. In this way the plant can better absorb nutrients and carry out photosynthesis, and at the same time the field has better air and light penetration, which can also prevent many diseases.

The above is the relevant introduction to the key points of tomato cultivation techniques. I hope it is helpful to everyone.
