What are the benefits of picking leaves from tomatoes

One of the tasks in tomato cultivation and management is to pick leaves, why picking leaves, whether picking leaves will affect the growth, and what are the benefits of picking leaves for the growth of plants. What is the principle of picking leaves? how to pick leaves is good for growth. Let's learn about the correct method of picking leaves.

1. The method of picking leaves

When picking leaves for the first time, get rid of all the old leaves when you click on the second ear. Leave a functional leaf under the first spike, and then remove all the other leaves. When picking leaves for the second time, when you point the flowers in the fourth ear to the fifth ear, you should remove some of the leaves. Specifically, most of the leaves below the three spikes are removed, leaving petioles and leaflets to avoid and help heal. After picking the heart of the plant, the leaves are picked for the third time, and most of the leaves between the third ear and the fifth ear are removed.

2. Benefits of picking leaves

The first time to pick leaves is for ventilation and light, increase air circulation, avoid high humidity, reduce the occurrence of diseases, easy to spray thoroughly when spraying. , distribute evenly and increase the control effect. The second time to pick leaves is to make the flowers develop better and ensure nutrition, and some leaves need to be sacrificed. The third time to pick leaves is for photosynthesis, to increase the production of organic matter, mainly for light transmission.

3. Reasonable picking of leaves

The old leaves consume more than they are made, and the leaves that grow for two months need to be removed. Infected leaves are potentially contagious and have no photosynthetic capacity. We need to get rid of it. Leaves should not be picked too hard, and leaves that can provide sufficient photosynthetic products should be left. If you pick too much, the root system is easy to senescence prematurely. Leaf removal wound to avoid infection, can be sprayed with some fungicides. Pick leaves on a sunny day, the wound should be small, it is best to carry out at noon, high temperature and less bleeding.

4. Points for attention

Note that when the tomato fruit really changes from green to white, the leaves near the fruit can not be picked, otherwise the growth will be restricted, the reproductive growth will be suppressed and the fruit development will be suppressed. Production will go down. Don't take off healthy dark green leaves at will. Some macular leaves should not be removed as long as they are capable of photosynthesis. Do not pick too many leaves, and the two basal layers of leaves are almost removed.

Picking tomato leaves has many advantages, but picking leaves is fastidious, can not pick leaves at will, only diseased leaves and dead leaves can be removed without worry.
