Misunderstanding of picking leaves of Tomato

Tomato is a well-known vegetable, whether it is eaten raw or cooked is particularly delicious, the market demand is also relatively high, so there are more people to grow. While in the cultivation of tomatoes are often encountered picking leaves, but many in picking leaves are wrong, let's learn about it.

1. Excessively picking leaves

When picking leaves for a tomato, many people like to remove all the branches and leaves under the fruit. In fact, this practice is wrong. After all the leaves are removed, there is no way for the tomato to carry out photosynthesis, which will cause a shortage of photosynthates. The end result is that the fruit is small and deformed, and the yield and quality can not go up. In addition, it will lead to competition among tomatoes for nutrients, roots and fruits for nutrients, which is extremely disadvantageous to the growth and development of tomatoes.

2. Picking leaves too early

There is time for tomato leaves to be picked, and the leaf age of tomatoes is generally strong within 15-50 days, so they should be removed in time after the leaves are more than 50 days. Instead of removing the leaves 50 days before the leaves, when the photosynthesis of the leaves is strong, if the leaves are removed prematurely, the tomato will not be able to synthesize the nutrients needed for the growth and development of the fruit, and as the supply of nutrients exceeds the demand, the fruit will stop developing.

3. Pick when you see yellow

Many farmers choose leaves to remove, the first choice is to remove yellow leaves, in fact, this practice is not correct. The yellowing of tomato leaves is caused by many reasons, such as improper watering and fertilization will lead to yellowing of the leaves, or the root system of the plant will be damaged, and the leaves will turn yellow if they cannot absorb nutrients. When the leaves turn yellow, they can be restored by spraying green protective solution, so that the leaves can be restored to normal leaf color without having to remove them.

4. Removal of insect leaves

When removing the leaves, in addition to seeing the yellow leaves removed, many people will remove all the leaves with wormholes. For pests, you can choose chemicals to treat them. There is no need to remove all the insect leaves, only the seriously harmful leaves can be removed.

5. Remove the shade leaves

In addition to removing yellow leaves and leaves with insects, many friends also like to remove shaded leaves, and many people think that if they are not removed, it will affect the color of the fruit. In fact, there is no need to remove it all, you can find the temperature in the greenhouse to adjust, the fruit is not colored is not because of the leaves.
