When will the old tomato leaves be beaten?

Tomato is a kind of vegetable that everyone is familiar with, which has very high nutritional value, and the planting area in our country is also very large. When growing tomatoes, we need to do a good job of management. Especially the work of picking leaves to avoid consuming too much nutrition. When picking leaves, we should first pay attention to the removal of old leaves. So when do you want to beat the old tomato leaves? What are the points for attention? Let's take a look at it with the editor.

1. Leafing time

When we beat the old leaves of tomatoes, we should determine the time according to the actual growth of tomatoes. If the growth of the tomato is normal, then the leaves under the tomato node can only be removed during the green ripening period, that is, when the tomato fruit gradually changes from green to white. Do not beat leaves casually the rest of the time, even if there is a disease, when the area of the spot is not more than half, then you don't have to worry about it. If the leaves of the plant grow too much and too dense, then in order to improve the ventilation and light transmittance of the plant, we can remove the leaves at the bottom of the plant and remove the leaves at the bottom of the plant.

2. Points for attention

When beating leaves, if the leaves are dark green, and do not receive the harm of diseases and insect pests, do not produce macula, then they are still useful and can not be knocked off. As for the fruit at the bottom of the plant, if the leaves gradually turn yellow, appear a large number of maculae or are seriously damaged by diseases and insect pests, then these old leaves should be knocked out in time. Then the yellow leaves and old leaves in the middle and lower parts of the plant which are harmed by diseases and insect pests or other physiological diseases should be knocked out in time.

When the tomato is approaching maturity, the leaves at the bottom of the fruit of the plant should be knocked out properly. When beating leaves, we should pay attention to the quantity, the number of leaves should not be too much, keep at most two pieces at a time, so as to avoid harming its growth. At the same time, we should also pay attention to maintain the interval between the two leaves, at least for more than 10 days. Each leaf beating should be carried out at noon on a sunny day, not in the morning with dew, so as to avoid diseases caused by bacterial infection in the leaf wound. Similarly, it is not possible to beat the leaves in the evening to prevent the leaves from being unable to heal in time and get sick at night.

Finally, after leafing, we should pay attention to timely spraying natural Carex, that is, golden rue fat, and use it at the same time as drugs for the prevention and control of bacterial diseases. This can not only promote the photosynthesis of healthy leaves, but also prevent the wound from being infected by bacteria and avoid affecting the normal growth of tomatoes. When we are beating leaves, if we do not pay attention to the above matters, then the impact on the growth of tomatoes will be very great. Either the disease is serious, or it will cause leaf damage, too little fruit nutrition accumulation, hollow fruit, yield decline and so on.
