Farmers grow tomatoes, it is necessary to do reasonable leaf picking, how to do reasonable leaf pick

No matter what crop a farmer grows, experience is the most important thing. Lao Li of Houwang Village is a tomato planting expert with many years of experience in tomato planting. He summarized a set of high-yield cultivation methods for tomatoes.

The people of the village love tomatoes. The young people of the village started learning to grow tomatoes last year, and if they have any questions, they ask him for advice. <>

Due to their lack of experience in tomato cultivation, they could not even pick the most basic tomato leaves. After asking Lao Li's opinion, they knew that the leaves of the tomatoes were also very delicate, and Lao Li told him that the tomatoes should be picked reasonably. Through reasonable picking, the ventilation and light transmittance of tomatoes can be improved, and the color change of tomatoes can be promoted.

Through reasonable picking, the ventilation and light transmittance of tomatoes can be improved, and the color change of tomatoes can be promoted. We should all know that in the middle and late stages of tomato growth, the leaves of the lower part of the plant will gradually age and turn yellow, the light at the bottom is weak, and the branches and leaves are dense, which will affect ventilation and light transmission, and is not conducive to the expansion and discoloration of tomato fruits, so it is necessary to pick it reasonably, Lao Li said, in many ethnic groups, tomato leaves are too heavy to pick. <>

When yellow leaves are seen, they must be picked to prevent and control powdery mildew. The correct picking method is like this, the picking principle of tomato is: when the tomato fruit reaches the green ripening stage per panicle, the fruit is fully grown and begins to change color, and the lower and upper leaves cannot be picked; The color is dark green, there are no pests and diseases, and the leaves without yellow spots cannot be removed; The principle of tomato leaves is:

The old leaves at the bottom can be removed when they are normal senescence and the leaves turn yellow, but the time can not be too long, the leaves in the middle and lower parts of the plant are seriously damaged by pests and diseases, or other physiological diseases and are seriously yellowed and aged, you can take preventive measures to pick leaves, and pick them reasonably: it is best to pick 2-3 leaves each time, but not too much. If you pick too many leaves at once, the remaining leaves will curl; Tomato picking is picked at intervals of 7-10 days; If the upper and middle leaves are too dense, the method of picking half a leaf can be used to improve the ventilation and light transmittance of the field; In addition, picking each leaf should be chosen on a sunny day at 10 a.m

Picking around 00, to prevent wound infection, leaves should not be picked even on cloudy days. At night, do not cut the leaves, so that the wound does not heal and become infected in time in the humid night.

I think that if you want to pick the leaves properly, you should be careful when picking and don't pick too much.

I think that if you want to pick the leaves properly, you need to pick a certain amount of leaves, and too much or too little is not good.

It is necessary to be familiar with the leaf stage of tomatoes, and carry out a small part of leaf picking.

I think that for such a thing, it is necessary to consider it in terms of its comprehensiveness.

When the green is ripe, it can begin. Be sure to pick the leaves in the morning to reduce pests and diseases and not affect yields.

In different places, the specific time is different, and it is necessary to pick the leaves reasonably according to the height of the plant and the situation of the plant fruit.

It needs to be removed when it has already borne fruit, so that more nutrients can enter the fruit, and the appropriate time should be selected according to the specific situation of the variety and the surrounding fiber banquet environment.

1. Carry out the first defoliation when the second spike flower, the first defoliation is mainly to remove the lower old leaves, the specific operation is to leave a functional leaf under the first spike flower, and remove all the remaining leaves, which is conducive to ventilation and light transmission, and can also make it easier for the liquid to reach the plant when spraying. When the point of the 4th-5th spike flower is the critical period of management, at this time the lower fruit is developing, the nutrient demand is large, the 4-5 spike flower is not easy to point in, in order to promote the development of flowers should be appropriately increased the concentration of the agent, and then on the premise of ensuring the nutrients ** appropriate leaf, the specific operation is to remove two-thirds of the leaves below the three spikes, the petiole should not be broken off together, but to leave two leaflets per leaflet, so that the wound heals quickly, not easy to be infected with diseases, and leaves can also make organic matter, Those who can provide sufficient spring for the fruit lack enough nutrients.

2. Wait until the plant is beaten for the third time, mainly between the three spikes and the five spikes, and the second part of the third is also removed. Reasonable defoliation can not only ensure the photosynthetic products required for fruit growth, but also not cause field shading.

Tomato leaves can be removed, picking leaves is appropriate, the first defoliation is completed when the second spike flower is pointed, the first defoliation is usually the lower yellow leaf is cut off, the specific step is to leave a functional leaf under the first spike flower, and all the other leaves are removed, which is conducive to wind and light permeability, and can also make the medicine easier to reach all parts of the plant when spraying. When the 4th-5th spike flower is the key period of the management method, at this time, the fruit development period below, the market demand for nutrients is strong, the 4-5 spike flower is not easy to point, in order to promote the growth and development of the petals as much as possible to increase the drug concentration value, and then there is to ensure the supply of nutrients under the premise of moderate defoliation, the specific step is to remove two-thirds of the leaves below the three spikes.

The leaves and stems should not be broken off together, and each leaf should be left with 2 branches, so that the wound heals quickly, and it is not susceptible to pests and diseases, and the leaves can also be used to produce organic compounds, which can give sufficient nutrients to the fruit. Tomatoes can tolerate drought, but not flooding, and the soil environment regulations are not very strict, so in order to increase yield, it is necessary to select a soil layer with a thick soil layer, loose and rich, and high water and fertilizer retention efficiency. After deep ploughing and raking, it was changed to a box with a width of 80cm and a height of 16 24 cm, and the width of the box ditch was 33cm, and each compartment was planted in 2 rows.

In the top dressing, the effective ratio of nitrogen, phosphorus and potassium is 1:1:2, 3000 5000kg of decomposed organic fertilizer is applied per mu, 25kg of phosphate fertilizer and 20kg of potassium fertilizer (or 80kg of grass ash) are applied to each other.

Tomatoes should be fertilized moderately during the growth period, and should not be applied with basal fertilizer, and must be combined with phosphorus and potassium fertilizers. Generally, seedling fertilizer is applied after transplanting slow roots to promote the growth and development of leaves and stems. The first ear of fruit gradually grows larger and then the second fertilization is carried out to promote the fruit to grow large, and the medium and late ripening varieties also need to be in the first.

After the first and second ears are picked, fertilization is carried out 3 or 4 times. During the growth and development period of fruits, leaf fertilization was carried out with Boshemai potassium dihydrogen phosphate aqueous solution, which was beneficial to fruit ripening and improved efficiency. After transplanting and slowing down the roots, it is necessary to cultivate soil and consolidate the soil, and water injection should be manipulated during the full bloom period of the first inflorescence to avoid flower and fruit drop caused by the growth and development of leaves and stems.

After the first ear of fruit set, the plants need more water, so they need to be watered in time, and pay attention to the drainage pipes during the rainy season.

It can be removed; Generally, it is necessary to remove the tomato when it is sunny and when the tomato is growing well, which can promote the better growth of the tomato.

It can be removed; When the fruit reaches the green ripening stage, it can be removed at this time.

Tomato leaves can be removed; We have to look at its time and the quality of the leaves, and then choose the right time, otherwise it will have a great impact on them.

To grow tomatoes in a plastic greenhouse, the leaves must be picked. After the tomato is ripe, there are a lot of aging leaves in the lower part of the tomato, and these leaves are to be beaten by the grower. Only by striking these old leaves can the tomato plant be exposed to light through ventilation and be less infected with some diseases.

If these old leaves are not broken in time, they are absorbing nutrients from the tomato plant. If you want tomato trees to grow better, you need to beat these old leaves in time. If you find that the tomato leaves are sick or old, you should pick them off in time.

But in the process of beating leaves, there are technical issues that need to be adhered to.

If the leaves of the tomato remain green, free from pests and diseases, and the leaves do not turn yellow, then the tomato tree does not need to beat the leaves. The leaves can still help tomatoes grow better. In this way, tomatoes can be produced.

If the leaves of the lower part of the tomato or the lower part of the tomato have turned yellow, have yellow spots, or have developed pests and diseases, these leaves should be beaten in time. When the tomato is about to ripen, the bottom of the tomato tree and the leaves underneath the tomato should be patted in time to keep the tomato tree ventilated. If these leaves are present, they will compete with the tomato for nutrients, affecting the growth of the tomato.

Tomato trees have yellow leaves, which are caused by pests and diseases, and this kind of leaves should be beaten in time. Because these leaves have viruses, they cannot be shed in time and can be transmitted to other healthy leaves. Eventually, the whole tomato will die, and the yield of the tomato will naturally be affected.

Leaf beating cannot be done at one time, and only two leaves can be beaten at a time. Also, if you shoot the leaves next time, the last time and the interval must be more than 10 days. The time to threh the leaves is usually chosen in broad daylight.

Leaves are not hit in the morning and evening. Because there is dew in those two phases. When the time comes to beat the leaves, the plant wound is prone to infection.

After beating the leaves, you should apply some pesticides. This is mainly to make the leaves better photosynthesize, which is more conducive to the growth of plants.

I talked about a few things to keep in mind when beating the leaves on the tomato, as well as the handling work to be done after the leaves are beaten. There are many benefits on tomatoes. Tomatoes are too dense and prone to problems, and tomatoes are not big.

In order for the yield of tomatoes not to be affected, it is necessary to rationally adjust the number of leaves. You can't beat the leaves on the tomato blindly, you have to take it one step at a time. If you beat the leaves for the first time, the tomatoes will bloom.

The first leaf picking is commonly known as "picking the bottom leaves", and the leaf picking time is mostly carried out when the first ear of fruit begins to show color. Focus on removing 1 or 2 leaves above the cotyledons of the tomato plant. By removing these bottom leaves, the growth of tomato stems and vines in the early stage can be promoted, so as to promote and flourish the trees.

In addition, these bottom leaves are not large in the lower growth, but may consume nutrients, if they are removed in the middle and late stages of tomato growth, one is dense branches and leaves, and it is more difficult to pick the bottom leaves, and the other is that the bottom leaves are close to the mulch film or the surface, which is easy to become the "source of infection" of the disease, so it should be removed as soon as possible.

1.Before the fruit of the ear is fully grown and begins to turn red, the upper leaves of the ear should not be knocked off, so as not to affect the production of nutrients by the leaves to supply the fruit.

2.Leaves that are dark green, free of pests and diseases, and free of yellow spots cannot be knocked off, as these leaves still contribute to the yield of tomatoes.

3.The leaves of the lower part of the fruit of the first ear turn yellow, and the old leaves with severe yellow spots or diseases and insects can be removed.

4.The middle and lower parts of the plant can be knocked off if the leaves are seriously yellowed and senescent due to serious pests and diseases or other physiological diseases.

The first point of injection should be the injection of this drug, and it is done at noon, and the amount should be paid attention to when the second day is shot, so that it can be adjusted, the third point should pay attention to the basic method, and the fourth point should be noted that the whole branch should be very slender when it is shot.

Tomato leaf thrashing is done to increase the yield of tomatoes. It is one of the common management methods. the principle of tomato defoliation; First, the upper leaves of the bottom ear of fruit should not be knocked off until they are fully grown and begin to turn red, so as not to affect the supply of nutrients.

Second, it is necessary to remove the old leaves with yellow spots or pests and diseases at the bottom.

You can get rid of the old leaves so that you can better supply nutrients to the new ones. I cannot damage other parts while I hit it.

If you don't pick the old leaves, the old leaves will compete with the fruit for nutrients, so that the eggplant does not grow big, each plant should pick only the upper leaflets, until the eggplant is ripe, at least 2 to 3 times, so as to ensure the growth of the eggplant. Excessive foliage of eggplant will cause overlapping leaves and block the conversion of light energy. It will also cause dense ventilation between eggplant plants, poor ventilation and light transmission conditions, and will also cause flower and fruit drop, fruit deformity and poor color, and affect yield and quality. Eggplant leaf picking is usually to remove those old leaves, yellow leaves, diseased leaves on the plant that have lost their photosynthetic function and cannot effectively produce nutrients for the plant, as well as dense leaves and shading leaves that affect the growth and development of eggplant.

<> leaf picking is generally after the harvest of the previous crop, in order to promote the recovery of the tree and the expansion of the subsequent fruit, so we need to carry out artificial fertilizer to provide the nutrients needed for growth. Eggplant is pruned with double stems, and after the eggplant is formed, the two outward side branches are cut off, leaving only two upward double stems. Generally, the 7th fruit is topped to promote the early ripening of the fruit.

When the eggplant stares, knock off the 3 leaves at the base.

Each leaf picking should be done at noon on the day of the eye, and avoid picking the leaves in the morning or evening. Because of the high humidity in the morning and evening, germs can easily infiltrate through the wound. After leaf picking, it is necessary to spray a fungicide in time to prevent the disease from causing death.

If the new leaves at the top or top of the plant are not fully developed, the photosynthesis capacity to produce nutrients is still very low, and the growth and development of new leaves, plants, roots, and fruits require a lot of nutrients, then the branches and leaves should not be carried out.

It is advisable to pick less trouser holes on the side branches, because the leaves on the side branches have little effect on the permeability of the plant, and will not cause shade and affect the growth. At the same time, the lateral leaves are also responsible for producing nutrients for root growth. Eggplant leaves should not be picked too much at a time, the same as one or two points, there are too many picks at one time, and the plant nutrition is easy to keep up, after all, there are fewer leaves for photosynthesis, and the law of leaf picking is to pick leaves in turn from bottom to top.
