What s the deal with tomatoes with four or five leaves spaced apart in a layer of fruit?

The habit of many vegetable farmers is that once the tomato sits on the fruit, all the leaves under the first ear of fruit will be knocked off, causing the first ear of fruit to expand very slowly and not grow large; When the fruit is picked, all the leaves under the second ear are removed, and so on, and when the top (four spikes, five spikes) is picked, the plant is left with only a few leaves at the top. Sometimes in order to save trouble, a lot of leaves are knocked off at one time, in fact, this practice is very unscientific.

Leaves not only photosynthesize, transport nutrients, but more importantly, provide nutrients to the roots. The photosynthetic ability of leaves is strong, which can provide sufficient carbohydrates for the growth and development of roots and promote the growth of roots. "Roots are raised by leaves, and leaves are grown by roots". The root system and leaves of vegetables are interdependent, interdependent, mutually reinforcing and indispensable.

Therefore, it is not recommended to knock off all the leaves under the fruit, it is better to keep 3 or 5 leaves under the fruit.

As for how many leaves to keep, it should also be adapted to local conditions, depending on the season. For example, in summer, when the temperature is high, you can leave a few more leaves under the fruit: first, it can protect the fruit from the sun; Second, it can block sunlight from reaching the ground, so that the ground temperature is not too high, and it plays a role in protecting the root system of plants.

On the contrary, in winter, you can knock off more leaves in the lower part: first, because the light is weak in winter, more leaves can increase the light transmittance, which is conducive to fruit coloring and plant growth; The second is to let the sunlight shine on the ground as much as possible, increase the surface temperature, and facilitate the growth of roots and plants.

If there is fruit, see if the fruit is too heavy to crush the branches, or there are insects, but this weather is unlikely; If the soil is white and cracked, it is a lack of water; It's also possible that it's too cold.

There are two reasons why the leaves on the top of the tomato can be rolled, one is to have a viral disease, and the other is to spray the concentration of plant hormones such as tomato to cause the damage caused by spraying the medicine to preserve the flowers, if it is not the second reason, it must be a disease.

The types of tomato virus disease include mosaic type, leaf curl type, striped leaf type, leaf curl type, yellow top type, necrotic type, etc., among which the disease caused by tobacco leafcurl virus (TLCV) infection, the symptoms are leaf curl type.

Viral diseases are difficult to treat and need to be prevented in advance.
