What if the tomato is dead?

Tomato is the scientific name for tomato, an annual or perennial herb of the solanaceae family. In the north and south of China have a more extensive cultivation, tomato nutritional value is very high, both raw food, fried food, but also can be used for processing into sauce, juice and so on. It is very popular in our country, but when we grow tomatoes, there are often dead trees. What about dead tomatoes? Let's take a look at it together with Xiaobian below!

1. The reason why tomatoes die

1. Death after tomato planting

The reason for tomato death after planting may be due to planting too deep and not doing a good job of weeding after watering. At the same time, if the capillary roots of tomato seedlings are burned by freezing injury, it will lead to capillary root damage. When applying fertilizer, if too much fertilizer is applied, especially excessive chemical fertilizer, it will cause seedlings to burn roots, and seedlings will wither and rot. Or after planting, tomato seedlings are damaged by pests such as root-knot nematodes, such as colonization with eggs, soil containing eggs, etc., which lead to tomato seedling death.

2. Dead trees in full fruiting period

Tomato die-off mostly occurs during the winter cold season. The main reason for tomato death in full fruiting period is caused by excessive watering. During the day, the temperature in the greenhouse is relatively high, and the water evaporation rate is relatively fast. This leads to a large amount of water demand for the aboveground part of the tomato plant, but it is difficult for the root to absorb water, resulting in a contradiction that causes the plant to wilt and die.

3. Causes of disease

Tomatoes are vulnerable to disease during their growth. Common diseases such as root rot, root rot and blight are major diseases that can cause death of tomato plants. Root rot causes the root or initial stem base of tomatoes to sink gradually, hindering nutrient transport. Cause tomato plant top stems and leaves because of lack of nutrition and gradually wilted, serious when dead. However, blight will be manifested as wilting of stems and leaves. After the disease is aggravated, the leaves gradually turn yellow from the lower part to the upper part, and finally the roots will rot and die.

Second, what about dead trees?

Tomatoes in the planting, we should pay attention to timely watering, and also do a good job of hoe. If wilting occurs, remove the soil immediately and allow the roots to dry. Greenhouse planting, to control the greenhouse temperature, the temperature should not be too high or too low. Before planting, some biological agents can be properly applied to enhance the disease resistance of tomato plants. If there are diseased plants, they should be treated in time. When infected by root-knot nematode, we should use lilac spore preparation to irrigate roots in time. Finally, when watering tomatoes in their full fruiting period, they should be watered with small water frequently, not flood irrigation.

The above is a simple introduction to how to do tomato dead trees. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
