Management Technology of Color conversion period of Tomato

Tomato is a kind of vegetable that many people like to eat very much. it can not only be fried, but also used in cold salad. it is a vegetable with high nutritional value and is welcomed by many people. Because the planting area of tomatoes is still relatively large, and when growing tomatoes, management is very important. Especially during the color conversion period. So how to manage the tomato color conversion period? Let's take a look at it with the editor.

1. Scientific fertilization

The color conversion period of tomato is a very important growth period. This period directly affects the yield and quality of tomatoes. Therefore, we should first do a good job in fertilization, in fertilization, mainly organic fertilizer, with a variety of nutrient elements. The most important thing is to apply the right amount of potassium fertilizer, the right amount of potassium fertilizer is very beneficial to the expansion and coloring of tomato fruit. It should be noted that potash fertilizer should be applied before the color conversion period, because the plant absorption of potash fertilizer can not be absorbed immediately, it takes a certain amount of time to be fully absorbed. If it is applied during the color conversion period, it will basically have no effect.

2. Temperature regulation

In the tomato color conversion period, the temperature adjustment is more important, the appropriate increase in temperature is conducive to the color of tomatoes. But we must pay attention to the degree of temperature increase, tomato fruit ripening is generally from the bottom up, so if there are only one or two ears of fruit and change the temperature, then it is very disadvantageous to the overall growth. And if the temperature is too high for a long time, then tomatoes are prone to overgrowth, falling flowers and fruits, and so on. Therefore, in the tomato color conversion period, the temperature is kept at about 28 degrees during the day and 15 degrees at night.

3. Reasonable leaf thinning

After the tomato enters the middle and later stage of growth, it is necessary to do a good job of thinning leaves. Reasonable leaf thinning can improve plant permeability and promote fruit coloring. But we must control the degree of leaf thinning, not excessive leaf thinning. During the color conversion period of tomato, the main leaf thinning objects are the old leaves, yellow leaves and diseased leaves in the lower part of the plant. There are some leaves that will block the sun, so the leaves in the lower part of the red fruit must not be removed. Otherwise, it will affect the photosynthesis of the plant and lead to the decrease of nutrient accumulation, which will not only affect the coloring of the fruit, but also hinder the expansion of the fruit.

4. Pest control

Finally, of course, we should do a good job in the prevention and control of diseases and insect pests. The humidity in the shed will increase, so the incidence of disease will increase. Therefore, during the color conversion period, we should focus on the prevention and control of diseases and insect pests, such as Botrytis cinerea, early blight and so on. First of all, it should be reasonably ventilated and dehumidified, and then properly sprayed to prevent it. After the occurrence of the disease, we should pay attention to check out the specific disease in time. Then make the corresponding measures, select the corresponding agents for prevention and control. When spraying chemicals, it can be used together with some foliar fertilizers such as chitin and amino acids, which can effectively enhance leaf resistance.

The above is a brief introduction to the management technology of tomato color conversion period. That's all for today's introduction. This article is for reference only. I hope it can help you all.
