Should cucumbers be topped, and should cucumbers be topped? When is the best time to top?

Cucumbers need to be topped. Cucumber topping can be done in the morning on a sunny day, when the vine grows to about 1 meter, if the main stem is flowering, use scissors to cut off the surrounding side branches.

Cucumbers grow fiercely under the conditions of suitable temperature and sufficient moisture, and if they are not topped in time, they will not only affect the amount of fruit set, but also affect the quality.

When topping cucumbers, it is necessary to pay attention to disinfection before topping to prevent cross-infection, and hands and scissors should be cleaned with soapy water or disinfectant.

Friends who grow cucumbers will ask a question about whether cucumbers should be topped and why they should be topped.

As long as you are a friend who grows vegetables, you may plant a few trees. In general, cucumber is one of the easier vegetables to grow, with rapid emergence of seedlings, simple planting, little management, and short-term harvest. There are three main ways to top cucumbers:

1. Leave only the main branches, and cut off the side branches. This method is suitable for varieties with main vines and melons, and the side vines can be cut off. For example, the cucumbers, Prince Charming cucumbers and American cucumbers are planted with female flowers when there are two or three true leaves, and melons are produced, and the top is full of melons, and there are twins and triplets.

Second, timely topping to promote the development of side vines. This method is suitable for varieties with the main vine not very fruiting and the side vine mainly bearing melon, and it must be topped in time to let the side vines grow as soon as possible. For example, the Golden Mountain cucumber, with the Prince Charming cucumber is sown in one day, planted in a field, the same management, when the Prince Charming cucumber is fruitful, the Golden Mountain cucumber also grows to more than two meters high, there is no female flower, and within a few days after the topping, almost every side vine has melons.

3. No topping and no pruning. This method is suitable for varieties with strong growth and melon bearing on both main and side vines. That is, after planting, you can leave it alone, neither topping nor cutting the side vines.

For example, when I planted the ground tiger cucumber and the ground cucumber for the first time last year, I kindly built a shelf, but only one melon was produced on the main vine, and then the branches were pruned, and there were no two. This year, there was no scaffolding, so it crawled everywhere, and as a result, as soon as the melon vine was opened, the melons in one place, the main vines and side vines were all melons.

Friendly reminder: 1. In the case of unclear variety performance, you can observe first, if the main vine bears melons in a lower position, you can consider cutting the side branches; When the main vine reaches more than one meter and there are no female flowers, topping can be considered.

2. The topping and pruning of cucumbers, regardless of whether the branches are old or tender, should be carried out with scissors, and it is easy to have bitter cucumbers by hand.

Whether cucumbers need to be topped depends on the cultivar and growth, and different types of cucumbers require different prunings

1.Cucumber varieties with side vines are mainly pinched or cut off the growth point when 4-5 true leaves appear.

2.Varieties that rely on the main vine and the side vine to produce melons at the same time do not top, and do not cut off the side vines. This type of variety is easy to produce side vines after fruiting, does not need to be topped, allows the main vine to grow upward, and is framed and tied when the plant grows to about 30 cm.

3.Cucumber varieties dominated by main vines do not top, and cut off the side vines.

4.For the cucumber that binds the stalk, choose the right time to top the cucumber before it reaches the top of the rack.

The above is the answer to whether cucumbers need to be topped, I hope it will help you.

Do you want to top cucumbers on the balcony? Do you want to thin the buds?

Do you want to top the yellow sedan melon? When is the best time to top? To top, topping time, cucumber topping time depends on the growth rate of the cucumber and the growing conditions.

When the cucumber branches and vines grow to about 1 meter, you can see cucumber flowers on the branches and vines, and then you can water the cucumbers on the flowers. To prepare for topping, prepare a pair of scissors that have been cleaned and disinfected before topping to avoid infection of cucumber shoots and vines.

The responsibility of the cucumbers grown in the greenhouse is to cover them. When the cucumber seedlings in the greenhouse grow to a certain length, the continuous growth of the cucumber must be controlled, because the cucumber seedlings that are too long and too busy will exceed the carrying capacity of the greenhouse, affecting the ** of cucumber fertilizer and water, the ventilation and ventilation of cucumbers and the lighting effect of cucumbers, therefore, the cucumbers planted in the greenhouse should be purified and pruned at the top, and the area of cucumbers planted in the greenhouse is effective. Cucumber topping in the greenhouse can be done manually without the need to spray controlled fertilizers.

After topping, the space in the greenhouse can ensure the normal production of cucumbers in the greenhouse!

As for the cucumbers that vegetable farmers grow on the ground, due to the large planting area of cucumbers, vegetable farmers do not have extra time to fertilize cucumbers one after another, and also let cucumbers grow freely on the ground. Vegetable farmers grow two to three crops per year. In order not to delay the planting of the next crop of vegetables, when it is time to plant the next crop of vegetables, the vegetable farmer will decisively pick all the cucumbers that are growing, no matter how big or small, then uproot the cucumber seedlings, clean them, re-fertilize and prepare the land, and then start planting the next crop of vegetables!

Therefore, topping cucumbers without topping is not absolute. It depends on the cultivation of cucumbers in the local area. In our northeastern region, all cucumbers planted on the ground are not topped.

In order to achieve high yield and high harvest of greenhouse cucumber planting, vegetable farmers will decide the topping time according to the actual growth of greenhouse cucumbers, and they will also choose to top the greenhouse cucumbers at the best time!

Cucumbers need to be topped, and generally the branches of cucumbers are topped at a distance of about one meter at this time, which is conducive to the rapid growth of cucumbers.

It must be topped; Generally, when the cucumber vine grows to about one meter, it needs to be topped and cultivated, and Xixiao can make the cucumber grow more vigorously and with macro, and the nutrients can be fully absorbed and utilized.

Cucumbers do not need topping and topping.

Most plants have apical dominance, but the form and degree of manifestation varies depending on the plant species. Plants with a strong apical dominance have almost no branches, such as many varieties of sunflowers.

Tomatoes and other plants have a weak apex dominance and can grow many branches. The apical dominance of the shrub is extremely weak, with little distinction between the main stem and the branches. Most plants belong to intermediate types, such as rice, wheat, etc.

Summary. Hello, the reasons are as follows: 1. The temperature is low in the early stage of growth, so the normal growth of the plant is inhibited, or the vegetative growth is too vigorous, resulting in serious growth and flower topping.

2. The root system is damaged in the greenhouse The temperature is unstable, especially the temperature during the day is too high, but the moisture content of the soil is sometimes insufficient, and because of unreasonable fertilization or crop rotation, the organic matter content in the soil decreases, so it will affect the root system of cucumber. Sometimes the humidity is high or the amount of irrigation is too high, resulting in the soil being wet, but the surface temperature is too low, and it is very easy to root the phenomenon. 3. The permeability of the soil lacking nutrients is poor, which affects the respiration of the root system and cannot provide sufficient nutrients to the above-ground plants.

4. The daily use of pesticides is not standardized, a large number of insecticides or fungicides are used, and the use is too frequent, which will lead to the failure of the plant to grow normally, resulting in the phenomenon of melon topping.

The reason for cucumber topping.

Hello, the reasons are as follows: 1. The temperature is low in the early stage of growth, so the normal growth of the plant is inhibited, or the vegetative growth is too vigorous, resulting in serious growth and flower topping. 2. The root system is damaged in the greenhouse The temperature is unstable, especially the temperature during the day is too high, but the moisture content of the soil is sometimes insufficient, and because of unreasonable fertilization or crop rotation, the organic matter content in the soil decreases, so it will affect the root system of cucumber.

Sometimes the humidity is high or the amount of irrigation is too high, resulting in the soil being wet, but the surface temperature is too low, and it is very easy to root the phenomenon. 3. The permeability of the soil lacking nutrients is poor, which affects the respiration of the root system and cannot provide sufficient nutrients to the above-ground plants. 4. The daily use of pesticides is not standardized, a large number of insecticides or fungicides are used, and the use is too frequent, which will lead to the failure of the plant to grow normally, resulting in the phenomenon of melon topping.

Prevention and control methods should first be adjusted for the temperature in the greenhouse, neither too high nor too low, need to be controlled within a reasonable range, at night, the temperature is low, but to maintain above 10 degrees, in the day because of insufficient light and lower than 20 degrees, then it is necessary to close the ventilation holes, cover the grass curtain insulation. Reasonable fertilizer and water management, fertilization using a small amount of frequent application of the principle, fertilizer do not directly contact the roots, so as not to hurt the roots, appropriate amount of watering, try to choose warm water, to avoid flood irrigation caused by soil permeability deteriorated, after watering can be properly loosened, to maintain soil permeability. If there are cloudy days or low temperature days for several days in a row, remedial measures should be taken, and if there has been a melon topping phenomenon, the ripe fruits should be removed in time and the surrounding female flowers should be removed together.

For the root system to maintain, especially in winter, do not leave too many flowers, otherwise it will only make the root system weaker.

<> cucumber topping is best carried out in the spring of each year, and the young leaves that grow on the cucumber vines need to be cut off when topping, and at the same time, it is necessary to provide an appropriate amount of water for the cucumber after pruning, so as to create a more humid growth environment for it, and also need to provide the right amount of nutrients for the cucumber to improve the growth rate of the plant.

1. Topping time.

Topping cucumbers requires choosing the right time. Cucumbers grow more vigorously in spring, so it is best to top cucumbers in spring, and you also need to observe the weather before topping, it is best to choose to top cucumbers in the cooler period of spring, and at the same time avoid rainwater polluting cucumber topping wounds.

2. Topping method.

When topping cucumbers, it is also necessary to take the correct topping method. First of all, you need to choose scissors with sharp edges, and then use scissors to cut off the young leaves and shoots that grow on the top of the cucumber plant, inhibit the growth of the main branch of the cucumber, and promote the cucumber to grow more side branches to differentiate with the flower buds and bear fruits.

3. Provide moisture.

Cucumbers are suitable for growing in a more humid environment, so cherry oranges need to provide an appropriate amount of water for cucumbers after pruning, keep the soil in a moist state, and pay attention to the choice of water source when providing water for cucumbers, it is best to provide mineral-rich river water or lake water for cucumbers, so that the plants can grow better.

4. Supplement nutrients.

Cucumbers have a greater demand for nutrients in the process of growth, so they also need to provide an appropriate amount of nutrients for cucumbers after pruning, so that cucumbers can grow better, and it is best to use nitrogen, phosphorus and potassium compound fertilizer when providing nutrients for cucumbers, and at the same time, the fertilizer needs to be diluted and provided to cucumbers, so that the plant grows more vigorously.

The steps of cucumber topping should start from the topping time, topping tools, finding branches and vines, topping position disturbance, and post-maintenance.

1. Topping time.

The timing of cucumber topping is uncertain and needs to be determined according to the growth rate of the cucumber. Generally, when the branches and vines of cucumbers grow to about 1 meter, it is suitable for topping, and this height is the vigorous growth period of cucumbers.

2. Topping tool.

Before topping, prepare a pair of scissors, however, the scissors need to be cleaned and disinfected to avoid bacterial infection.

3. Look for vines.

After the cucumber grows flower bones, carefully observe the flowering branches and vines to determine whether they belong to the main stem or the side of the gentle wild branches, and also select and determine the incision location.

4. Top position.

After determining the cucumber branch vine that needs to be pruned, if it is the main stem flowering, you can use scissors to cut off the surrounding side branches; If it is a side-branched vine flowering, you need to top the main stem of the cucumber and pluck it.

5. Later maintenance.

After the cucumber topping is completed, if possible, it can be shaded or applied to the incision position, and after the cucumber vine incision position is dry, normal watering, top dressing, light and other maintenance management can be resumed.
