The latest tomato leafing methods and matters needing attention
Tomato leafing can not only improve the permeability between plants and reduce the possibility of breeding of diseases and insect pests, but also eliminate the leaves affected by diseases, reduce the spread of bacteria, wipe out the old leaves, and avoid unnecessary consumption of nutrients. So how to beat the leaves of tomatoes? What should I pay attention to? Come and have a look with the editor.
First, the method of leafing.
1. Old leaves
In the later stage of tomato growth, there are many aging leaves in the lower part of the plant. If these leaves are not knocked out in time, they may not only lead to plant disease, but also cause unnecessary waste of tomato nutrients, so this kind of old leaves must be knocked out in time.
2. Thick leaves
Tomatoes are a bit thick, which will seriously affect the ventilation and light transmittance of tomatoes, so they can be knocked off together when beating leaves, but some technical problems should also be followed when beating leaves. It is not suitable to hit too hard, otherwise it will cause a serious decline in photosynthetic efficiency, which is very detrimental to the growth of tomatoes.
3. Bottom blade
When the tomatoes are about to mature, the leaves at the bottom and below of the tomatoes should be knocked out in time, so as to ensure the permeability in the greenhouse, and their existence will also compete for water and fertilizer in the fruit growth and development, affecting the later yield.
4. Yellowing leaves
When there are yellow leaves in tomatoes, they should also be knocked out in time, because these yellow leaves are most likely caused by diseases and insect pests. If they are not knocked out in time, because the leaves may already have powerful germs, then they will be slowly transmitted to other leaves, eventually causing the whole plant to die, and the yield will naturally be affected. However, if the yellow leaves are caused by lack of water and fertilizer, they should be patched one by one. As long as the management of fertilizer and water is strengthened, the yellow leaves can return to normal and do not need to be knocked out.
II. Points for attention
When beating leaves, you can't knock off all the leaves at once, at most the bottom two leaves at a time, and there must be an interval of more than 10 days before beating leaves twice, so as to ensure that tomatoes thrive. In addition, you should also pay attention to the time when beating leaves. You can't beat leaves sooner or later. Generally, you choose noon when beating leaves, because there is dew on the leaves in the morning and evening. After picking the leaves, the wound will be infected, and the temperature is high at noon. After picking leaves, the wound will become dry. Of course, you can also sprinkle some pesticides after cutting leaves to prevent germs from getting in.
The above is the introduction of tomato leafing methods and matters needing attention. I hope I can help you. If you want to know more about it, please follow us.
