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 removed from the leaves of the lower part of the red-red fruits, so as to avoid the decrease of photosynthetic accumulation of the plants.
