Tomato color change refers to the process that the fruit turns from green to red and gradually matures. In the color change stage of tomato fruit, if the management operation is improper, it is easy to make the tomato fruit form a "flower face". The temperature regulation in the shed is unscientific and the management method is not appropriate, which can easily lead to uneven coloration of tomatoes.
In order to make the tomato color and high in commodity quality, the following three points must be paid attention to in the management of sheds:
1. Reasonable fertilization: The base fertilizer is mainly organic fertilizer, and various nutrients are reasonably matched. When applying potassium fertilizer to promote the expansion and coloration of tomato fruit, it needs to be used before the color change period. This is because it takes a certain time for the potassium fertilizer to be absorbed and utilized by the plant after being applied to the soil. Potassium fertilizer should be applied with base fertilizer or initial application. After the fruit turns red, the application of potassium fertilizer can not achieve the expected effect.
2. Temperature regulation: During the development of tomato fruit, the daytime temperature should be controlled from 25 °C to 30 °C, and the night temperature should be between 13 °C and 17 °C.
3. Avoid excessive leaf thinning: appropriate leaf thinning in the middle and late stages of tomato is conducive to fruit coloring, but should not be overdone. In the color-changing period, the leaves should be removed from the old leaves and yellow leaves of the diseased leaves and the lower leaves of the plants, and the leaves that are shaded around the fruit should not be completely removed from the leaves of the red fruits, so as to avoid the decrease of photosynthetic accumulation of the plants. Affect the expansion of the fruit.

- Various vitamins (such as vitamin A, B vitamins, vitamin C, vitamin D, vitamin E, etc.)
- Minerals (e.g. calcium, iron, zinc, selenium, etc.)
- Dietary fiber
- Other specific nutrients, such as amino acids, enzymes, probiotics, plant extracts, etc
The purpose of nutritional supplements is to meet the nutritional deficiencies that individuals may have due to special needs, dietary habits, digestive and absorption problems, health conditions (such as disease, pregnancy, aging, etc.) or other reasons. They are usually available in the form of tablets, capsules, oral liquids, powders, etc.
When choosing a nutritional supplement, one should consider an individual's physical condition, diet, and possible side effects. Although nutritional supplements can provide additional nutrients, it does not mean that they are a substitute for a balanced diet. The best strategy is usually to get most of your nutrients through a varied diet and use nutritional supplements when necessary under the guidance of a medical or professional. In addition, excessive consumption of certain nutritional supplements may also pose health risks, so it is recommended to consult a professional before use.
