Latest Summer Tomato Growing Techniques and Management Methods Tutorial

Tomato is a vegetable with very high nutritional value; it can be stir-fried as a vegetable, or eaten raw in cold dishes, and so on. It is loved by many people, and when we grow tomatoes, their management work is naturally very important. Especially during the high temperature and strong light of summer, management must be strengthened. So how should tomatoes be managed in summer? Below, the editor brings you the technical management of summer tomatoes. Let's take a look!

1. High-ridge planting

Many people, when growing tomatoes through the summer, use flat-bed planting or shallow-furrow cultivation. And after planting, to avoid weed damage, they also cover with black film, but in a high-temperature and strong-light environment, the soil temperature rises very easily, and when carrying out farming operations, these are done directly on the film. This causes the plastic film to cling tightly to the ground, leading to compaction between the rows in the soil. The soil's permeability becomes worse, causing the roots' absorption of water and nutrients to be blocked, and the plant's growth also weakens as a result, reducing the speed of fruit swelling. So when growing tomatoes in summer, we must pay attention to mainly using high-ridge planting.

2. Cultivating strong plants

When growing tomatoes in summer, pay attention to controlling the amount of fruit retained. If too much fruit is retained on the lower part of the tomato plant, it will cause excessive nutrient consumption, easily dragging down the plant and affecting later flower and fruit growth, so fewer fruit should be retained. Especially on the lower part of the plant, if the plant's stem is thin and weak, then the first truss of flowers should first be removed to cultivate a strong plant. Then the amount of fruit retained can be appropriately increased; if the plant grows vigorously, then about 2 fruits can be retained on the first truss, about 3 on the second truss, and about 5 on the trusses above. However, note that the first flower of each truss should be removed and must not be pollinated.

3. Pruning and leaf removal

Many people choose to use shade netting in summer to lower the temperature, but this easily causes the plants to grow leggy, and the tomato plant stems also easily become thin and weak, so chemical growth control should be the main method. Chlorophyll, paclobutrazol, etc. can be used, and the concentration should be adjusted according to temperature changes and plant growth. In summer, unless the plant's branches and leaves are too luxuriant and have seriously affected the plant's permeability, leaves should not be removed; otherwise, try not to remove leaves. Then, after the last truss of fruit has set at the top, at least two leaves should remain above the head before topping, to shade the top fruit. Finally, the top must not be completely removed, to avoid premature aging.

4. Cooling the greenhouse

As just mentioned, summer temperatures are very high. So if growing in a greenhouse, be sure to do a good job of cooling. Temperature can be lowered through ventilation; besides this, shading and water spraying are also main cooling measures. From 10:00 to 15:00 each day, pay attention to covering with shade netting. At the same time, an appropriate amount of cooling agent can be sprayed on the greenhouse film, and water can be sprayed inside the greenhouse. If high-temperature weather continues, then small amounts of water should be poured into the furrows, and ventilation should be done well. Finally, if no plastic film is covering the ground, then after each watering a hoeing should be carried out, to avoid soil cracking due to lack of water and affecting root growth.

The above is a brief introduction to the technical management of summer tomatoes. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
