The management of tomato color change period is very important. If the corresponding management measures are not taken during this time, or the management measures are improper, it will result in poor color, uneven color and poor commerciality of tomatoes, thus affecting the economic benefits of tomato sales. Xiaobian said that it causes the uneven color of the tomatoes and the coloring skills, I hope to help everyone. First, the reason for the uneven color of tomatoes 1. The temperature is too high or too low The determinant of tomato coloring is mainly the synthesis of lycopene in the fruit. When the temperature is lower than 13 degrees, or higher than 32 degrees, lycopene is blocked, which affects the color change of the tomatoes. 2, unreasonable fertilization During the process of tomato planting and fertilization, the proportion of nitrogen, phosphorus and potassium is imbalanced, or the nitrogen fertilizer in the color-changing period is too high, which will affect the formation of lycopene, resulting in uneven color change, such as the often-fat fruit on tomatoes. , green fruit, brown fruit, etc., are caused by these reasons. 3, excessive leaf thinning Tomatoes should be removed from the leaves and the lower leaves of the plants, the yellow leaves and the leaves around the fruit. The other leaves should not be removed. It is necessary to know that roots are raised by leaves. If the leaf surface is too small, it will affect the accumulation of photosynthetic nutrients, making the root system prone to premature aging, thus affecting fruit yield and quality. For the last batch of tomatoes in the tomato coloring period, at least 4-6 leaves should be left. Second, tomato coloring skills 1, temperature control When the temperature is in the range of 23-28 degrees, it is easy to form lycopene, which promotes the color change of the fruit. Therefore, the planter needs to do the corresponding measures of heat preservation and ventilation. 2, scientific fill light In order to ensure that the tomatoes have sufficient light, a reflective light curtain can be added to the shed wall to remove the dust on the shed film and spray the photosynthetic nutrient film fertilizer, which is beneficial to the plant to absorb a large amount of light fertilizer, light energy, illumination, and compatibility. Conventional fertilizers and nutrients supply plant growth to the limit. When the tomatoes are close to maturity, the leaves and diseased leaves around the fruit are removed to promote normal coloration. 3, timely application of potassium, boron fertilizer Potassium fertilizer is conducive to the coloration of tomatoes. Generally, high potassium fertilizer is applied with water at the beginning of the results, and 8-10 kg per mu is suitable. The lack of boron in the tomatoes causes the fruit to appear green backed fruit. Therefore, the boron fertilizer is sprayed three times during flowering, and the leaf surface of the boron-containing leaf fertilizer can also be sprayed to promote uniform coloration of the tomatoes. 4, spray red In the case where tomato coloring is difficult, a redness agent may be sprayed. When using the redness agent, pay attention to the dosage to prevent excessive ripening and affect the fruit storage.
