Tomato is a vegetable crop, which can not only be eaten raw, but also can be used to stir-fry all kinds of dishes. Used for cooking also has the role of refreshing, welcomed by many people. Therefore, there are a lot of people growing tomatoes now. When growing tomatoes, coring is essential, which is of great help to the production of tomatoes. So how to pick the heart of the tomato? The following editor brings you the method of picking the heart of tomatoes, let's have a look!

1. Time to pick out the heart

Before picking the heart, we must first determine the time of picking the heart of the tomato. Generally speaking, when the tomato plant grows the last spike of flowers, it is the best time for the tomato to pick its heart. When picking the heart, keep about 3 leaves in the last ear. After the leaf is mature, it can provide sufficient influence for the plant and promote the expansion of the ear at the top of the plant. Avoid the top fruit due to lack of adequate nutrition and stunting, abnormal fruit and so on. Moreover, it can also play a sunshade role for the fruit, promote the tomato to change color, and avoid physiological diseases.

2. The method of picking out the heart

After the tomato is planted, the first inflorescence of the tomato plant should be treated with hormone. Make the internodes at the lower end of the first inflorescence grow strong branches, and then wait until three or four inflorescences, retain the first two leaves of the fourth inflorescence for coring. It was cultured as the second basic branch. The inflorescence of each branch should be determined according to the growth space and growth of the plant. Under normal circumstances, if there are too many lateral branches, the yield is easy to be reduced. Therefore, the number of inflorescences per tomato should be kept at about 12, no more than 15 at most.

It takes about two months for tomatoes to be on the market after they are ordered to bloom. Then in the color conversion period, if affected by high temperature and strong light, then tomato fruit lycopene production is blocked, resulting in tomato prone to many green fruits. Therefore, when we pick the heart, we should mainly leave branches in the axils of the upper leaves, and then pick the heart when the lateral branches grow to 3 leaves. After picking the heart continuously for a long time, you should pay attention to picking leaves properly. Ensure the growth of lateral branches and avoid poor growth of flower buds. When picking leaves, all the leaves in the lower part of the main stem can be removed, and the petiole should be removed to prevent Botrytis cinerea.

3. Points for attention

Many growers pick their hearts as soon as the tomatoes grow into top flowers. At this time, the top leaves of the plant do not grow out, which can easily lead to lack of nutrition and stunting of the plant. The increase in the proportion of deformed flowers and abnormal fruits will also have a great impact on the expansion of the fruit, resulting in a decrease in yield. And the ripening time of tomato fruit is generally when the light is strong, and if the top fruit is lack of leaf shading, it is easy to burn, split fruit and other adverse phenomena. Therefore, when we pick the heart, we must pay more attention to it and wait until the top leaf grows out before we can pick the heart.
