Management points of early flowering stage of Tomato

Tomato is a very common vegetable in China, and the planting area is getting larger and larger. When we plant tomatoes, we need to adjust our management methods according to the growing period of tomatoes. In the early flowering stage of tomatoes, management is more important. So how to manage tomatoes at the early flowering stage? The following editor brings you the key points of the management of the early flowering period of tomatoes. Let's have a look!

1. Temperature management

Temperature control is very important in the early flowering stage of tomatoes. After the tomato enters the flowering stage, the temperature should be controlled at about 25 degrees during the day and 13 degrees at night. The temperature difference between day and night should not be too small, otherwise it will affect the flowering and fruiting of tomatoes and reduce the yield and fruit quality. And tomatoes are very sensitive to changes in temperature during flowering. Especially four days before and after flowering. Must pay attention to control the temperature, the temperature must not exceed the range of 12-30 degrees, otherwise it will have a great impact on the flowering, pollination and fertilization of tomatoes.

2. Pruning and branching

Then, in the early flowering stage of tomatoes, we have to do a good job of pruning and branching. In particular, we should pay attention to the size of the first flower in the tomato plant. If the flower in the first ear is too large, it will hinder the pollination and fruit setting of other flowers, so it should be removed in time. Then, when bearing the first ear, you should pay attention to the time of forking. Not too early, if too early, it will affect the early growth of tomatoes. It should usually be knocked off when the branch grows to about 11 centimeters. Then after the first ear is seated, the strips on the upper part of the plant are removed. Be careful not to let the plant produce too many wounds, and do a good job of lifting vines at the same time.

3. Matters needing attention in dipping flowers

In the early flowering stage of tomatoes, dipping in flowers is very important. When we dip in the flower, no matter what it is, we should pay attention to adjust the concentration according to the change of temperature. And remember the flowers that have been dipped in to avoid repeated dipping. The dipping time should be early rather than late, and should be carried out in the morning of the day of flowering. And because the first flowering stage of tomatoes is usually in early spring, low temperature and high humidity can easily cause diseases. Therefore, we also need to do a good job in the prevention and control of diseases, can be dipped in the flower liquid to add an appropriate amount of hydantoin, Shijiale and other agents.

4. Fertilizer and water supply

Tomatoes expand rapidly within half a month after blooming, so be careful to make sure there is plenty of fat and water. In good weather, it can be properly watered, and then irrigated with an appropriate amount of high-potassium compound fertilizer and biological bacterial fertilizer. At this time, we should pay attention to properly raise the temperature, if the ventilation is good, then the temperature can be raised to about 28 degrees. Promote the photosynthesis of tomato and increase the accumulation of photosynthetic matter in the plant.

The above is a brief introduction to the key points of tomato early flowering management. That's all for today's introduction. This article is for reference only. I hope it can help you all.
