When is the best time to fork tomatoes? What to look out for?

In the process of tomato cultivation, pruning is a very common measure to increase yield. Pruning is to remove excess side branches in the pruning process to reduce nutrient consumption, avoid vigorous growth, and promote fruiting. If the tomato is not thred, the growth of side branches needs a lot of nutrients, and the tomato will easily grow, resulting in only tomato seedlings, and the fruit growth and absorption of nutrients will be less, so the yield will be reduced, so timely pruning is a way to improve the yield.

Although tomato threshing can produce high yields, the timing of threshing is also particular. If you beat the branches, you will consume nutrients and avoid them, and you will not be able to control the prosperity; For example, this farmer can easily affect the growth and development of the root system if the root is beaten too early, and there is a period for the weak varieties that are not allowed to shoot too early. So what is the best time to play a stick?

After the first ear of tomato fruit is set, it is time to beat the branches when they are the size of eggs. In winter, the temperature in the greenhouse is low and the humidity is high, which generally reduces the fertilizer and water, or can be watered and fertilized every once in a while, in order to avoid insufficient nutrients for fruit growth, it is necessary to remove excess side branches, control plant growth, reduce plant consumption of nutrients, and let nutrients be limited to fruit growth.

How do you do it? After the first ear of fruit sits, the lower branches of the fruit are directly removed, so that the nutrients are prioritized to the fruit expansion. Some friends will ask, should the branches on the first ear of fruit be removed?

The upper branches can wait until the first ear is harvested, and then the second ear can be removed from the lower branches.

However, it should be noted that pruning and pruning should not be carried out in continuous cloudy and rainy days, because this can easily lead to bacterial diseases of the plants. We try to do it between 10 a.m. and 12 a.m. on a sunny day, and the temperature is relatively high during this time, so it is still a good time to do it.

After the pistol, you can spray a fungicide to prevent infection with gray mold and downy mildew after the pistol, and you can choose manganese zinc plus enoylmorpholine. If you don't want to use pesticides, you can also use white sugar and vinegar. Spray directly on the wound to prevent bacterial spores from entering the wound and infecting the wound with bacterial diseases.

Therefore, in the process of planting tomatoes, plant management is also a more important link, such as thrashing can not only increase yield, but also improve ventilation and light transmission, reduce nutrient consumption, it is necessary to pay attention to the method, time and management after thrashing, which can lay the foundation for high yield of tomatoes.

Forks are required before the plant can bloom. When making a fork, you need to use sterilized scissors to make a fork. Nitrogen fertilizer and potassium fertilizer should be supplemented in time after forking to promote the growth of plant rhizomes, and appropriate amount of watering should be used to keep the soil moist.

Tomato forking should be timed, neither too early nor too late, suitable for the first inflorescence of the plant has bloomed or young fruits begin to develop, at this time the advantage of forking is earlier, more nutrients to supply flowers and fruits to develop.

The first forking of tomatoes is generally carried out when the axillary buds have grown to more than three centimeters, and too late consumes too many nutrients, which is not conducive to the growth of the plant.

If it is a single-pole pruning, only one main stem is left for each plant, and all the other side branches are cut off to make the nutrients more concentrated, so that the later stage can better flowering and fruiting.

When making a fork, it should be done on a sunny day and at noon, the temperature is high, and the wound will heal faster. Do not get water on the wound after crossing.

Cultivation of tomatoes.

1. Temperature. The temperature suitable for tomato development is 24 to 26, between which the tomato should develop.

2. Illumination. Tomato is a light-hungry crop and is sensitive to light. Sufficient light can make tomatoes grow vigorously, with thick stems and strong resistance to stress; Lack of light will cause tomato development to be stunted, and in severe cases, there may be a risk of losing leaves, deflowering, and even fruit rotting.

3. Moisture. Tomato is a deep-rooted crop, tomato is afraid of drought and flooding, but it needs drainage very much, so the water given to the tomato can not be more or less, and you must remember to drain it in time.

After flowering and fruiting, hit the top fork of the seedlings, if you are planting in a greenhouse, please ask a professional.

When the tomato grows 20 cm tall, it is forked, and as long as the root grows into a split root, it can be forked.

Tomato (tomato), also known as tomato, persimmon. The ancient name is June persimmon, good news three yuan. In Peru and Mexico, it was originally called "wolf peach".

The whole body is viscous glandular hairs with a strong odor. The stems are prone to lodging. Leaves pinnately compound or pinnate deeply lobed, leaflets very irregular, unequal in size, ovate or rectangular, margins irregularly serrated or lobed.

calyx radiate, lobes lanceolate, fruiting; The corolla is radiate, yellow. berries oblate or nearly globular, fleshy and juicy, orange or bright red, smooth; Seeds yellow. Flowering and fruiting period: summer and autumn.

With the appearance of small fruits, there is a little pressure when bending over.

On a rainy day. Is it good for forking tomatoes? Why?

Tomatoes on rainy days are taboo, and tomatoes on rainy days will cause diseases, and the whole plant will die in severe cases. We don't have tomatoes in our greenhouses, not to mention rainy days, generally cloudy days.

If you can't open the wind, you don't dare to fight.

The dangers of tomatoes on rainy days.

On rainy days, tomatoes are beaten, and the flow of wounds will cause the stems to be infected with tomato late blight, and then spread the leaves and fruits, and in severe cases, the whole tree will die. Tomato late blight spreads quickly, especially in rainy days, the drug control effect is poor, and it can not be effectively controlled for two or three days of continuous rain, which will cause infection in the whole shed, resulting in reduced yield or no harvest.

On rainy days, tomatoes are beaten, the tuyere of the greenhouse cannot be opened, and the humidity in the shed is high, and the wound will cause tomato gray mold.

After spreading, the gray mold infects the leaves, fruits. Cause rotten fruits and leaves, the stems continue to spread, and finally the whole plant dies.

On rainy days, tomatoes are beaten, the water in the shed is large, the stems and leaves are particularly tender, and it is easy to break and hurt the stems and leaves of tomatoes when beating. Hit the tomatoes and break them together with a little bit.

On rainy days, tomatoes are beaten to cause burial and cracking, and disease prevention and control measures are taken.

Tomato late blight.

On rainy days, tomatoes are infected with late blight, which is manifested as brown at the wounds, and then gradually spread to the stems for a week, gradually expanding in area, the stems become thinner and dryer, and in severe cases, the whole plant wilts or falls over and dies.

Prevention and control measures: control the humidity in the shed, and immediately spray sterilize the whole shed with 1000 times of eugenol or 800 1000 times of silver fat after the wound is found to be infected with late blight, so as to prevent the spread of infection in leaves and fruits.

At the same time, apply the liquid medicine to the infected site with 50% promethane on the stem to prevent spread. Be careful to enlarge the area around the affected area as much as possible. After sealing the shed on rainy days, use 45% chlorothalonil in the evening.

Smoke sterilization to prevent the spread of infection.

Tomato gray mold.

On rainy days, tomatoes are infected with gray mold, which is manifested as gray-brown at the wound and dense gray mold layer on the surface, and then spreads, circling the stem, producing a large number of mold layers, and the stem is dry and dead in severe cases.

At the same time, the leaves are infected, and the disease gradually spreads to the leaves, and then they turn yellow and die, and a large number of mold layers appear on the diseased leaves.

The flowers and fruits are infected at the same time, and the flowers are infected with the disease and surrounded by mildew, and they wilt and fall.

Prevention and control measures: Enhance ventilation in the shed, and after finding that the wound is infected, quickly spray sterilization with 50% Herui 1000 times liquid or 40% pyrimethammine (Shijiale) 1000 1500 times liquid in the whole shed to prevent transmission. At the same time, apply the stem with 50% Pythium (Suclin) 2000 times (you can prepare a little heavier with appropriate content), and pay attention to enlarge the area around the disease as much as possible.

On rainy days, use 15% Pythium (Pythium) smoke agent, close the shed and light the smoke in the evening to sterilize.

Tomato threshing is best done in a sunny day with good ventilation, and the chance of infection is very high if the time and method are improper. During the vigorous growth period of the plant, the disease spreads very quickly, and the control effect cannot keep up, which can easily lead to yield reduction or even no harvest.

Unhappy. Because on rainy days it will cause the fork to be unsuccessful. This is a waste of material resources and time.

Learn tomato pruning and forking techniques in 3 minutes, and plant potted tomatoes on the balcony must learn skills.

1. Single-stem pruning method: each plant retains a main trunk, and all the other side branches are erased, and the main stem retains a certain ear and fruit for topping. 2. One stem and half pruning method:

Each plant retains one side branch under the main stem and the first inflorescence, and all the other side branches are erased, and when the side vines grow 2-3 spikes and fruits, the top is plucked, and only the main stem is kept to continue to grow. 3. Double-stem pruning method: each plant retains the main trunk and the first side branch under the first inflorescence, and all other side branches are erased.

First, how to fork tomatoes

1. Single-stem pruning method.

Only one main stem of each plant is retained, and all the other side branches are successively removed, and the main stem is topped after retaining a certain number of ears and fruits (generally 2-4 ears and fruits of peel oranges are retained).

2. One stem and half pruning method:

Each plant retains the main stem and a side branch under the first inflorescence, and all the other side branches are completely erased, and when the side vines grow 2-3 spikes and fruits, the topping is carried out, and only the main stem is kept to continue to grow.

3. Double-stem pruning method.

Each plant retains the main stem and the first side branches under the first inflorescence, and the other side branches and the regenerated branches on the double stem are completely removed.

4. Continuous topping and pruning method.

When. After the first and second inflorescences have flowered one after another, keep 2 leaves on the top of the second inflorescence for topping, and this main branch is the first fruiting branch. Then keep the first lateral branch that grows immediately under the first inflorescence, and leave the leaves for topping after retaining 2 inflorescences as the second fruiting branch.

5. Dry and prune.

Each plant retains 3-4 strong side branches, and each side branch retains 2-3 ears and fruits before topping.

Second, when is the right time to cross the tomatoes

1. Generally, when the side branches grow to about 7-10cm, reach the two leaves and one center, and cause obstacles to the surrounding leaves, flowers and fruits, it is more appropriate to carry out branching one after another. If the plant is weak, 1-3 leaves should be left on the branch.

2. The beating is generally carried out at the high temperature on a sunny day, so that the wound heals quickly and the wound flow is less.

3. Cutting time too early will reduce the growth of the plant, making the plant easy to senescent and reducing the fruiting ability. If the pruning time is too late, it is easy to induce the growth of the tung tree, which leads to excessive nutrient consumption of the plant, which affects the fruit set and fruit expansion.

Method:

First, the tomatoes are forked in the early stage

1. In the early stage of fruiting, try not to knock off the forks, and form a certain area of branches and leaves to promote root development and plant growth, and flower bud differentiation is also good. Because the main purpose of cultivating strong plants and promoting flower bud differentiation in the early stage of the plant is to promote flower bud differentiation. If the fork is too early, it will seriously limit the growth and development of vegetables in the later stage, for example, the first ear of fruit is not large, it is easy to appear green peel fruit, and the plant is prone to premature aging.

2. Do not rush to wipe the fork in the slow seedling stage and flowering period, promote the growth of the aboveground part and the development of the root system, and wait until the fruit enters the rapid expansion period, and then erase the fork in time.

3. The side branches should be beaten until 10 centimeters, and 2 centimeters should be left to prevent infection, and the sun will not go down in the afternoon, and it will not be played too early in the morning to prevent wound infection.

Second, the tomato forking method:

1. The main thing is to pinch off all the shoots at the top of the trunk when there is a lot of difference in the height of the trunk, so that it will not grow taller again. Of course, for useless side branches and side branches that are already tall, the top shoots should also be pinched off.

2. Tomatoes are divided into single and double-headed pruning methods. That is, leave 1-2 heads for each plant, and break off the rest of the branches when they grow to 10 cm long. Early-maturing varieties (except for self-capped) should leave 3-4 ears and fruits to pinch their heads, and medium and late maturing varieties can leave 6-10 ears and fruits to pinch their heads as needed.

This way it won't grow any longer and the nutrients will be retained for flowering and fruiting.

3. The forking and pinching of tomatoes should be determined according to the variety, planting density, and cultivation on or without the frame. If it is planted with limited growth varieties and cultivated without frames, each plant should have 2 to 3 branches when it grows to a height of 30 cm, and 2 leaves should be pinched after the main branch and the third flower appeared, and 2 leaves should be pinched after the side branch was left with 1 flower.

4. If it is an infinite growth variety with scaffolds, it is generally used to use single-rod shaping and double-rod shaping, single-rod shaping is to leave only the main branch, all the side branches are removed, and the double-rod shaping leaves one main branch and one side branch.
