The vast majority of farmers take good care of tomatoes when planting, and the water and fertilizer will not be less, resulting in tomatoes growing full, more side branches, faster leaves, and more luxuriant plants. Generally this situation will generally think that this is very good! In fact, it is not, if the plant grows too dense, it will cause flowers, rotten fruits, and the color of the fruit is also poor, so the cultivation of tomatoes has the habit of picking leaves.
Leaf picking is a technical job, and if it is not picked well, the yield may be reduced by half. Let's take a closer look!
Everyone knows that the more leaves a tomato has, the more nutrients it produces and accumulates, and it grows faster, which is conducive to the expansion of the fruit. However, too many blades will also affect ventilation and light transmission.
If there is the presence of old leaves and diseased leaves, not only will the nutrients be provided less, but also prone to disease, and removing old leaves and diseased leaves is conducive to plant growth and fruit.
However, too much leaf picking will reduce the manufacture and accumulation of nutrients, which will be very unfavorable to the growth of the plant. So how should the leaves be picked?
Two examples of leaf picking
Picking leaves of big red and pink tomatoes:
The first leaf picking time is mostly carried out when the first ear of fruit has just begun to show color. Focus on removing 1-2 leaves above the cotyledons of the tomato plant.
The second time to pick leaves, it is generally necessary to wait until the first spike of fruit grows to the average size of the beverage bottle cap. Leave a leaf under the first panicle and remove all the lower parts of it.
It can be done to promote the growth of tomatoes in the early stage of stems and vines, and achieve the purpose of promoting trees and vigorous trees. Then these leaves are not large in the lower length, but will consume nutrients, if the tomato growth in the middle and late stages and then removed, first of all, the branches and leaves are dense, it is difficult to remove the leaves, and the bottom leaves are close to the mulch or the surface, easy to become the "source of infection" where the disease occurs, so it is said to be removed early, not to suffer losses.
Cherry tomato picking:
The method of picking the leaves for the first time is similar to that of big red and pink tomatoes.
But the second time to pick the leaves, it is necessary to wait for the largest fruit of the second spike to be about one circle longer than the bottle cap. This time, after leaving a leaf under the second panicle, you can remove all the leaves below it.
The third time to pick the leaves, you can wait until the largest fruit of the fifth ear grows to the size of the adult's finger belly, and then leave a leaf under the fifth panicle, and then remove the lower leaf.
Tomato leaf picking is also divided into different types, different species have different methods, and the whole leaf picking process is different.
Pick the leaves on a sunny morning, try to avoid even cloudy days to hit the leaves, which is conducive to the wound to dry and heal as soon as possible under the exposure of sunlight and higher temperatures. When picking leaves, try to avoid enlarging the wound.
What else should I pay attention to when picking leaves?
Pick late when there are yellow leaves in the lower part:
At this time, some people wondered, have all the yellow leaves occurred, do not hurry to pick them off and keep them for the New Year? It is not what is thought, because most people think of a decrease in chlorophyll after leaf yellowing, and photosynthesis has been greatly affected, but it is only hindered, and leaf photosynthesis has not stopped. If picked early, the photosynthetic products will be more insufficient, and the growth and development of tomato fruits will be more affected.
If there are yellow leaves, try not to pick them early, try to topdress, solve the problem of yellow leaves, and try to restore the yellow leaves to normal.
Excessive leaf picking:
Picking leaves too heavy will make the tomatoes hollow, and the top picks should not be too harsh. For example, if the upper ear leaves are removed, not only will the hollow fruit be formed, but the fruit is small, the yield is low, and it is also susceptible to direct light and sunburn. Therefore, when picking, 1-2 leaves should be retained above the upper panicle.
Rooting and preventing yellow leaves:
Yellow leaves are yellowing between the leaf veins of the whole plant from bottom to top, mostly caused by root dysplasia or root injury. It is recommended that vegetable farmers and friends can loosen the soil in time to increase soil permeability. Loosen and activate the soil, cultivate a developed root system, and choose a water-soluble fertilizer that can promote root growth when topdressing, its absorption capacity is faster, which can effectively ensure the adequate supply of nutrients and alleviate yellow leaves.
Leaf picking is necessary, but it is certain that the yield reduction is not picked well, so before picking the leaves, according to the variety and its own growth, after picking the leaves is conducive to the overall growth, but it is necessary to support more nutrients, at this time, topdressing can not only prevent yellow leaves, increase photosynthesis, but also raise the root system, provide a steady stream of nutrients to the plant.
When topdressing, it is recommended to use the easy-to-grow rooting type of Schrider's amino acid-containing water-soluble fertilizer, which can be combined with leaf picking and other means to increase the yield of tomatoes, which is specifically manifested in stimulating root growth, increasing photosynthesis, and alleviating various unexplained yellow leaf conditions that occur in tomato growth.
Water-soluble fertilizer containing amino acids - easy to grow and root type - barreled
Amino acid ≥ 100 g/L
Fe+Mn+Zn+B≥20g/L
Advantage 1:
Stimulate crop vitality, stimulate root growth, and shorten the time of slow seedlings.
Advantage 2:
Rapidly mitigates a variety of unexplained yellow leaf conditions that occur during crop growth.
Advantage 3:
Alleviate diseases and increase crop immunity. Effectively solve various drug hazards, improve crop resistance to cold, drought, lack of light, salt and alkali resistance, and prevent crop lodging and premature aging.
