Course Management of the latest Technical methods of Tomato in Summer

Tomato is a kind of vegetable with high nutritional value, which can not only be fried as vegetables, but also can be eaten raw with cold dressing. Loved by many people, when we grow tomatoes, its management is naturally very important. Especially when it is hot and bright in summer, the management must be strengthened. So how to manage tomatoes in summer? The following editor brings you the technical management of summer tomatoes, let's have a look!

1. High ridge planting

When many people plant tomatoes in summer, they are planted in flat beds or in shallow trenches. And after planting, in order to avoid the harm of weeds, it will also cover the black film, and in the high temperature and strong light environment, the temperature in the soil is very easy to rise, and in the agricultural operation, it is carried out directly on the film. In this way, it will cause the plastic film to cling to the ground, leading to the consolidation of the soil. The permeability of the soil becomes worse, which hinders the absorption of water and nutrients by the roots, weakens the growth of the plant and reduces the rate of fruit expansion. Therefore, when we plant tomatoes in summer, we must pay attention to high ridge planting.

2. Cultivate strong trees

When planting tomatoes in summer, you should pay attention to controlling the amount of fruit left. If the lower part of the tomato plant leaves too much fruit, it will lead to excessive nutrition consumption, easy to fall, and affect the growth of flowers and fruits in the later stage, so leave less fruit. Especially in the lower part of the plant, if the stem of the plant is thin and weak, then the first panicle flower should be removed and a strong tree should be cultivated. Then appropriately increase the amount of fruit retained, and if the plant growth is strong, then the first ear can leave about 2, the second ear can leave about 3, and the upward ear can leave about 5. However, be careful to remove the first flower in each ear and do not point the flower.

3. Pruning and leafing

In order to reduce the temperature in summer, many people will choose to use sunshade net, but this can easily lead to overgrowth of plants, tomato plant stems are also easy to become thin, so chemical control should be given priority to. Chlorophyll and paclobutrazol can be used, and the concentration should be adjusted with the change of temperature and plant growth. In summer, unless the branches and leaves of the plant are too luxuriant, which has a serious impact on the permeability of the plant, you can only beat leaves, otherwise try not to do so. Then after sitting on the top of the last ear of fruit, there must be at least two leaves to hit the head to shade the top fruit. Finally, the top can not be completely removed to avoid premature senility.

4. cooling in the shed.

As I just said, the temperature in summer is very high. So if it is planted in the shed, then we must pay attention to do a good job of cooling. The temperature can be reduced by ventilation. in addition, shading and water spraying are the main measures to reduce the temperature. Pay attention to covering the sunshade net at the time of 10-15:00 every day. At the same time, an appropriate amount of cooling agent can be sprayed on the greenhouse film, and water can be sprayed in the greenhouse. If the hot weather is continuous, then small water should be poured into the ditch to do a good job of ventilation. Finally, if the plastic film is not covered, then the intertillage work should be carried out after watering to avoid the lack of water leading to soil drying and cracking and affecting the growth of the roots.

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