Why don t the grapes you grow yourself bear fruit

Grapes are the fruit that most people love to eat, but there will always be problems in the planting process that grapes do not bear fruit, why do grapes not bear fruit? What should I do if the grapes don't bear fruit? Let's take a look!

Why don't the vines bear fruit?

1. The planted grapes may be female flower varieties, which cannot be pollinated and fertilized normally, and naturally cannot bear fruit, such as the common ancient varieties in the northwest of the country, such as the common ancient varieties of white chicken heart, black chicken heart, Lanzhou big grape, Anjiwen, etc.

2. Courtyard grapes often have sufficient fertilizer and water, and grow vigorously, and the growers do not understand the pruning technology, thinking that the more vigorous the growth, the better, resulting in long branches, serious internal shade, and poor maturity of branches and buds, which is not conducive to the formation of flower buds and fruits.

3. In the case of poor nutritional status of flower spikes, adverse climatic conditions (such as continuous rain and continuous high temperature) during the flowering period affect pollination, fertilization and fruit set.

What should I do if the grapes don't bear fruit?

1. Provide suitable soil.

Experienced people will find that grapes can be grown in many soil environments, but not in good or bad ways. If we give it the right soil, the grapes will grow faster and will produce a lot of fruit, which will taste very sweet. On the other hand, if we provide him with unsuitable soil, then either the grapes will not bear fruit, or the fruit will not taste good.

Grapes like to live in a loose and fertile soil, of course, the soil should also have good drainage, ordinary soil, either not breathable, or poor water retention, which is not conducive to the growth of grapes. If we provide the grapes with a soil that has a strong water retention, the yield of the grapes will be very high.

Second, the right temperature.

Grapes are not suitable for living in a cold environment, if the temperature of the environment in which it grows is lower than 12 degrees, then the grapes will stop growing and enter the dormant period, so its growth temperature must be higher than 12 degrees, and it is best to keep it at about 20 degrees, so that the grapes can flower and bear fruit normally.

3. Sufficient light.

The growth of any plant is inseparable from light, and the growth of grapes is the same, it is a plant that likes sunlight very much, and its growth needs enough light. If the grapes are given enough light, then their photosynthesis ability will be stronger, so that the sugar in the grapes will accumulate very much, so the grapes will ripen quickly, and the fruit will be very sweet.

The best way to solve the problem of potted vines not bearing fruit.

The reason why grapes in the yard do not bear fruit: the lack of light makes the grapes unable to produce organic nutrients, and the flower buds cannot be differentiated, so they will not bear fruit; If it is not pruned in time, let it grow, there are too many branches and buds, the nutrients are scattered, and there are no strong strips, resulting in no flowers and no fruits; Pest infestation is also the reason why it cannot bear fruit, and it is necessary to eliminate pests in time.

The first and most important reason why the grapes you grow are not fruiting is that you don't pollinate your grapes and don't bag your grapes.

No, the grape saplings will bear fruit in the second year after planting, so be careful to leave one or two bunches on each tree, as the saplings have not yet reached adulthood and the saplings need to grow. In the third year, during the peak fruit period, it is necessary to ensure that water and fertilizer are sufficient.

Grapes are our most common fruit, and people love them, and some people tend to plant a few in their yards, but many people report that the vines they grow have not borne fruit. What is the reason for this? What to do?

What is the reason why the grapes do not bear fruit.

1. Reasons for inconsequence.

1. Variety reasons.

Some friends may be cheated by the merchant when buying seedlings, buy seedlings of very poor quality, and then manage them diligently after planting, and this kind of seedlings will not bear fruit.

2. The time has not yet come.

Grapes especially have their own fruiting time, some seedlings are shorter when they are purchased, only 1-2 years, so no matter how good the planting management is, it will not bear fruit so quickly, and it will naturally bear fruit when it comes to the time of its fruiting.

3. Insufficient fertilizer.

Planting grapes is the key to fertilizer, apply enough base fertilizer, in summer and autumn, it is necessary to continue to apply fertilizer, in order to accumulate nutrients in the second year, so that in the spring of the next year, more branches and leaves can germinate.

4. The growth environment is unfavorable.

When growing grapes at home, light and ventilation are important, and if they are grown in an environment with insufficient light and poor ventilation, they will produce less and less fruit every year until they do not bear fruit.

5. Pruning. Prune once before the differentiation of flower buds in spring, top dressing once when germinating, and choose organic fertilizer for top dressing, which can provide sufficient nutrients for the plant, so that it can germinate more young shoots and lay the foundation for high yield.

What is the reason why the grapes do not bear fruit.

Second, the solution.

1. Growth period management.

After the flower bud differentiation, if there are too many young buds, an appropriate amount of wiping buds, and some too much unnecessary can be eliminated as soon as possible, which can reduce the nutrient consumption of plants. When the new shoots grow to 15-30cm, it is necessary to tie less in time, and at the same time remove the tendrils; At the same time, it is necessary to do a good job of topping, and the secondary tips below the fruit spike should be all removed, and the secondary tips above the fruit spike should be left with 2 leaves for topping.

After flowering, the inflorescence and the sleeve of the fruit tree should be prepared, and a well-grown inflorescence should be left on one fruiting branch, and the rest should be thinned.

What is the reason why the grapes do not bear fruit.

2. Fertilizer and water management.

Fertilization is essential for high grape yields, and studies have shown that for every 100 kilograms of grapes produced, kilograms of pure nitrogen, phosphorus and potassium need to be consumed. Therefore, after the fruit is harvested and before the new shoots are ripe, the fast-acting fertilizer is generally applied in 10-15 days of flowering, and the basal fertilizer should be applied during the fruit development period in July, and there are obvious weeds. Spraying low concentrations of borax solution and superphosphate solution at the flowering and fruiting stage can improve fruit setting and yield.

Before flowering, the soil should be kept moist to improve favorable conditions for flowering and fruit set, but the flowering period should not be watered, and the fruit needs a lot of water after fruit set, so it should be watered every 7-10 days according to climate change, but it should not be watered during the fruit coloring period, so as not to reduce the sweetness.

1. Variety problem: it may not bear fruit may be a variety problem, and the planted variety belongs to the female flower variety, which cannot be pollinated and fertilized, and naturally will not bear fruit. Common varieties include black chicken heart, flower leaf white chicken heart, Anjiwen and so on.

2. Improper pruning: During the management period, the plant grows vigorously, but if it is not pruned for a long time, the branches will grow, the internal branches and leaves will not see the light, and the maturity of the bud eye will be poor, so that the flower buds will not be formed and will not set fruit.

3. Climatic problems: If the flower spike itself is malnourished, and then encounters continuous rain or continuous high temperature weather, it will affect pollination and lead to normal fruit set.

Economic value. Wine is the most important processed product from grapes. Wine is a high-grade consumer product because of its cultural connotation. In China, its consumption has skyrocketed.

In addition, the newly developed grape seed oil has been used as an advanced nutritional oil for infants and the elderly, and as an advanced health oil for aerial workers and flight personnel abroad, and has attracted a lot of attention from the world.

Compared to other fruits, the diversity of grape products is much richer. According to the needs of life, the storage and transportation requirements of processed products, nutrition and health care and other factors, people also process grapes into raisins, grape juice, grape seed drink, grape seed oil and other common products.

Reasons why grapes do not bear fruit:

1.Unfavorable growing environment: When growing grapes, light and ventilation are important, if they are grown in a poorly lit and poorly ventilated environment, they will produce less and less fruit year by year, until they do not bear fruit.

2.Insufficient fertilizer: Planting grapes is the key to fertilizer, apply enough base fertilizer, in summer and autumn, it is necessary to continue to apply fertilizer, in order to accumulate nutrients in the second year, so that in the spring of the next year, more branches and leaves can germinate.

3.Variety reasons: Some friends may be cheated by merchants when buying seedlings, buy seedlings of very poor quality, and then manage them diligently after planting, and this kind of seedlings will not bear fruit.

4.The time has not yet come for the grapes to bear fruit, especially on their own, and some seedlings are only 1-2 years old when they are purchased.

Grapes do not bear fruit causes and solutions:

Insufficient lighting and poor ventilation will cause less fruit or even no fruit, so light and ventilation should be strengthened.

The fertilizer for grapes should be mainly basal fertilizer, and nitrogen fertilizer should be stopped before flowering.

Cut once a year in winter and 1 in summer. Including budding and tillering, topping and whisker removal operations.

This grape is cut with a knife before winter, cut off the third tooth from the trunk, and then buried in the ground, don't let the stroke, the grapes will start to bear in the second year, and then consult if you have any questions

The failure of the vines to bloom and bear fruit may be due to low temperatures, unsuitable soil, improper water and fertilizer, or infestation and disease. Prolonged temperatures below 15 degrees Celsius, severe soil rigidity and compaction, irregular application of water and fertilizer, disease and pest spread, will cause it to not bloom and bear fruit.

The reason why the vine does not bloom and does not bear fruit.

1. The temperature is too low.

The reason why the vine does not bloom and does not bear fruit may be caused by the low temperature, this plant needs to be in an environment above 15 degrees Celsius under normal circumstances to be able to grow and develop smoothly, if the temperature is too low for a long time, the plant will not flower and bear fruit, and even freeze to death.

2. Soil discomfort.

Soil discomfort can also cause the vines to not bloom and do not bear fruit, this plant is suitable for living in a soil with a loose and porous structure, good drainage and ventilation and a certain basic fertility, if the soil is too salinized or heavily acidified, it will lead to the phenomenon of no flowering and no fruit.

3. Improper water and fertilizer.

If the application of water and fertilizer is improper, it will also cause the vine to not bloom and bear fruit, such as too much watering, causing water rotten roots, too little watering causes plant drought, too much fertilizer is too dense to cause fertilizer to burn roots, too little fertilizer is too thin to cause long-term, serious malnutrition of the plant, it is recommended to use Trim water-soluble fertilizer, which will not cause harm to the crop.

4. Infected with diseases and insects.

Diseases and insects can also cause the phenomenon of grapevines not flowering and not bearing fruit, and the vines will be infected with pests and diseases because of unclean soil, the use of humus fertilizer, poor ventilation and other reasons, and the plants at this time will not only fail to bear fruit, but also begin to wither and die in serious cases.

1. Insufficient light: The sunshine time in the planting area is too short, which will cause the flower buds to be difficult to differentiate.

2. No pruning: the branches and leaves are dense, which reduces the ventilation and light transmission between the canopies.

3. Lack of nutrients: the demand for nutrients in the flowering and fruiting stages is greater, so more phosphorus and potassium fertilizers should be applied.

4. Improper watering: If the soil is too dry or too much water, it is difficult for the vines to flower and bear fruit.

The failure to bloom is usually due to lack of pruning or proper fertilization.

If there is not enough fertilizer in the soil or too much nitrogen fertilizer is applied to it, it will not bloom, and it is necessary to apply the appropriate fertilizer of pica phosphorus and potassium fertilizer to promote the differentiation of flower buds. Pruning is done once in summer and once in winter, and the buds that are too dense should be cut off, and the new ones should be plucked appropriately.

1.Varietal problemsGrape flowering and not bearing fruit may be a variety problem, if the planted grapes have degraded stamens and become a female flower variety, there will be a situation where only flowering and not bearing fruit. 2.

Improper pruning of the vines without pruning, the plant grows too vigorously, resulting in long branches, resulting in internal branches that cannot receive light, young shoots that do not have enough nutrients to grow, flower buds that do not form, and naturally do not bear fruit. 3.Climatic influencesIf the vines do not grow well, the flower spikes do not have enough nutrients for growth and development, and in the event of continuous rainy weather or high temperatures, the pollination of the fruit trees will be affected, resulting in the failure to bear fruit normally.

The lack of flowering and fruiting of the vines may be caused by a lack of light, so it is necessary to give more than 6 hours of light a day to allow the flower buds to differentiate smoothly. It can also be caused by a lack of pruning, so it is necessary to prune off the dense foliage in time to allow the canopy to have good ventilation. The lack of nutrients can also make it difficult for the vines to bear fruit, so it is necessary to apply more phosphorus and potassium fertilizers to supplement the nutrients during the flowering and fruiting period.

Grapes are suitable for growing in a sunny place, and when maintaining grapes, it is necessary to give more than 6 hours of natural light every day, if the lack of light will cause the flower buds of the grapes to fail to differentiate, and there will be no fruit. Therefore, it is necessary to ensure that the grapes are cultivated with sufficient light so that they can bear fruit smoothly.

Grapes need to be pruned properly during the growing process to bear fruit, and a lack of pruning will result in the vines not being able to flower. Therefore, the vines need to be pruned 1 3 times a year to remove the branches that are too dense and those that are not growing well, so as to increase the fruiting rate of the vines.

The lack of nutrients during the growth period of the grapes can also lead to the failure of the vines to flower and bear fruit, so the soil can be watered with a diluted organic fertilizer to replenish the nutrients, in addition to the flowering and fruiting period of the vines, it is necessary to apply more phosphorus and potassium fertilizers and less nitrogen fertilizers, so that the vines can bear fruit smoothly.

The vines are suitable for growing in moist conditions, but are not resistant to waterlogging. If there is water in the soil during the maintenance of the vines, or the roots are too dry, the vines will not be able to flower, so when maintaining the vines, it is necessary to water according to the dryness of the soil to ensure that the soil is in a slightly moist state.
