Where are the tomatoes from? Why does it only blossom but not bear fruit when planting?

Tomato is a very healthy vegetable with red skin and looks like an appetite. Tomatoes taste sour and sweet, both raw and cooked food have a certain flavor. Tomatoes are planted everywhere. Let's take a look at where the tomatoes come from. Why does it only blossom but not bear fruit when planting?

Where are the tomatoes from?

Tomatoes are native to South America and are widely cultivated in the north and south of China. Xinjiang is one of the most suitable regions for the growth of processed tomatoes in the world. Industrial tomatoes have high contents of red pigment and palmatine, less mold and good viscosity, so they are the best raw materials for processing tomato products. In particular, drought and little rain in Xinjiang, the occurrence of diseases and insect pests is relatively less, which is conducive to the development of pollution-free tomato products.

Xinjiang is also known as the three major centers of tomato cultivation and processing in the world, along with the River Valley of California and the Euro-Mediterranean region. Since 1998, the tomato products industry in Xinjiang has maintained a momentum of rapid development.

Second, why do tomatoes blossom but not bear fruit when they are planted?

1. Excessive vegetative growth

The plants flourish, the leaves are larger, the jointing is longer, and the stems are thick and thin. This may be due to the overgrowth of tomatoes caused by lack of rain, high temperatures or uncoordinated nutrition. As a result, the vegetative growth of tomatoes is too prosperous and the reproductive growth is insufficient, so the adjustment of tomato plants is very important to the management process of tomatoes, in which overflourishing plants have the greatest impact on tomatoes, because if the plants grow too much, it may affect the flowering and fruit setting of the plant, and then affect the yield of tomato. The reasons for this are as follows:

The light is insufficient and the temperature is too high. When the temperature is high, especially when the night temperature is high, the tomato will grow rapidly, the stem jointing is fast, the jointing is long, and it is not easy to set fruit.

Improper supply of nutrients. If the application of too much fertilizer, especially nitrogen fertilizer, will make the plant absorb too much nutrients, it is easy to grow too much.

Hormonal action. The use of quick-acting foliar fertilizer, which may contain some growth-promoting hormone, will make tomatoes grow too fast, resulting in nutritional imbalance and overgrowth of plants.

2. High temperature affects flower bud differentiation.

According to the results of the study, the high temperature encountered in the period of flower bud differentiation of tomato will affect the normal flower bud differentiation of tomato. Inflorescence abortion and fruit can not stop or can not complete normal pollination, resulting in non-stop flowers or abnormal fruit development.

How to manage the situation that tomatoes only blossom but do not bear fruit?

1. Shading and cooling measures should be taken after planting. Guard against overgrowth.

2. Some boron-containing foliar fertilizer should be sprayed before and after flowering to promote flower bud differentiation and improve fruit setting rate.

3. Reasonable watering and topdressing. In order to prevent tomatoes from growing, it is wrong for most vegetable farmers not to water them during the flowering period. In the time of high temperature and drought, if the tomato leaves appear curly, flowers white and other symptoms, must be properly watered. When watering, you can apply appropriate amount of phosphate fertilizer, do not apply a large amount of element fertilizer.

4. If there is a phenomenon of falling flowers, it is necessary to spray anti-falling element in time. Fangluo has the function of protecting flowers and fruits and reducing abnormal fruits.
