Matters needing attention in changing color of tomato

Tomato is a common vegetable in our daily life, it is both a vegetable and a fruit, during the tomato color change, its peel will be green and gradually mature, if not managed properly, it will cause the tomato to form a flower face. And if you want the tomato to change color evenly and improve the commodity, you should pay attention to a few points in the management. Let's take a look at it with the editor.

1. Temperature control

Many vegetable farmers think that increasing the temperature can promote the coloring speed of tomatoes, which is every mistake, because the fruits of tomatoes begin to ripen gradually from the bottom up, and if you change the temperature of the whole shed for the sake of the fruit on one ear, the advantages often outweigh the disadvantages. If the temperature in the greenhouse is too high for a long time, it will not only cause overgrowth of the plant, but also cause serious flower and fruit drop. In the tomato color conversion period, the temperature control should focus on the overall situation, keep it as usual, and there is no need for special management.

2. Avoid excessive leaf thinning

Tomato needs sufficient light during the color conversion period, and the leaves around the fruit undoubtedly affect its permeability, so it is necessary to remove it in time. Although this is beneficial to the color conversion of the fruit, it also has its disadvantages. Although a large number of thinning leaves can enhance the light transmittance, but the leaves are reduced, the photosynthesis of the plant leaves is also weakened, without synthesizing enough nutrients, it is very easy to lead to premature senescence of the plant, and after the imbalance of the proportion of leaves and fruits. It also has a great impact on the output. Therefore, in the tomato color conversion period to pay attention to reasonable leaf thinning, generally only need to remove the lower yellow leaves, old leaves, diseased leaves, do not thinning leaves too much.

3. Increase the application of potash fertilizer

There is no doubt that potash fertilizer can promote fruit expansion and facilitate fruit coloring, but the fertilizer effect is slow after potassium fertilizer is applied to the soil, and it does not play an important role in the fruit coloring period. Therefore, it is necessary to apply irrigation or planned fertilization in advance, generally speaking, there should be sufficient potassium fertilizer in the base fertilizer before planting, and after entering the young fruit stage, potash fertilizer should be applied in combination with watering, or foliar spraying should be provided to supplement the potash fertilizer needed by the plant.

4. disease prevention and control should be early.

Tomato has few diseases in the early growth stage, and the main diseases to be controlled are early blight and gray mold. Early blight, also known as ring blight, can damage stems, leaves and fruits. In the later stage, it will often lead to withered leaves, broken branches and early shedding of fruits. The varieties with strong disease resistance should be selected when sowing, and the seeds should be sown after disinfection and production treatment, and at the same time, they should be rotated reasonably, which can kill you with carbendazim, difenoconazole and flusilazole, and should be used alternately or mixed. Botrytis cinerea will not only harm the fruit, but also damage the stems and leaves, and in serious cases, 1/3 of the fruit will rot. The prevention and control of Botrytis cinerea should be done from the environment, scientific ventilation, and reduce the incidence of the disease.
