Reasons for the uneven coloration of tomatoes and solutions
Tomatoes, the scientific name of tomato, can be used as both vegetables and fruits. It is said that the most famous dish is not a tomato soup. However, in the recent reaction of vegetable farmers, the coloration of the tomatoes grown is very uneven. Why? In the face of uneven coloring of tomatoes, how to solve it? Next, Xiaobian will explain these two issues.
First, the reason for uneven coloration of tomatoes
1, temperature
When the temperature in the shed cannot meet the growth temperature requirement of the tomato, it will seriously affect the coloration of the tomato, resulting in uneven coloration.
2, fertilization
If the amount of nitrogen fertilizer applied is too large, the nutrients required for tomatoes are too rich, which causes difficulty in coloring.
3. Planting density
Due to the high density of tomato planting, the plant will appear to be elongated or the branches and leaves will squeeze each other, affecting the growth of the tomato, thereby affecting the ripening of the tomato fruit.
4, management
Did not wipe the shed film in time, so that the sun did not come in; did not promptly remove the old sick and sick, causing tomato coloring is not good.
Second, effective measures to solve tomato coloring
1, pharmacy red
Due to the low temperature in winter, the planting temperature cannot meet the requirements for lycopene production, so coloring is difficult, so it is possible to use a chemical to perform redness before picking.
2, do a good job in greenhouse greenhouse insulation measures
The most effective measure for greenhouse insulation is to use greenhouse heating agent, which can increase the temperature in the greenhouse 3-5, the surface temperature of 4-6 degrees, and increase the concentration of carbon dioxide, which will prompt the tomatoes to start the results in advance, which is conducive to coloring. Evenly.
3. Add organic fertilizer and bacterial fertilizer
In addition to the rational application of nitrogen fertilizer, it is necessary to increase the application of organic fertilizer, phosphorus and potassium fertilizer, especially the fermented fermented organic fertilizer with the application of gold baby micro-fertilizer, which can not only improve the soil environment, improve the fertility, but also increase the resistance of tomato to disease. Inverse, it can make tomatoes more productive and evenly colored.
4, reasonable close planting
Before planting tomatoes, it is necessary to set a reasonable planting density, as long as it can make the tomatoes full of light, which is conducive to uniform coloration.
5, timely spraying growth regulators
a. When the tomato fruit grows up, spray 40% of ethephon, remove the old dead leaves in time, and prevent the occurrence of pests and diseases.
b. Spraying 500-800 times of coloring agent in tomato young fruit stage, fruit expansion stage and maturity stage is beneficial to increase tomato sugar content and promote uniform coloration.
