How many years does the vine bear fruit How many years does it take for the vine to bear fruit?

It takes 2-3 years for the seedlings to bear fruit, and there are some differences between different varieties.

For example, Kyoho grapes can bear fruit in the second year after the fixed value, while sapphire grapes take three years to bear fruit.

The minimum temperature required for grape growth is about 12 -15, the minimum ground temperature is about 10 -13, the optimal temperature for flowering is about 20, and the optimal temperature for fruit expansion is 20 -30.

After the spring budding of grapes, if the temperature rises rapidly, it is easy to cause the branches to grow, which is manifested as the length of the knots is not full, and the flowering period is easy to be fertilized.

Introduction to planting grape jujube trees.

The vines prefer dry and hot summers and can tolerate some low temperatures, but not severe cold. In alpine areas, they need to be buried in the soil for winter. They are suitable for planting on slightly acidic to slightly alkaline sandy soils with good drainage and moderate humidity, and do not grow well in acidic soils.

Originally found in Brazil and South America, the grapes are now partly grown in Fujian, Guangdong, Zhejiang, Guangxi, Sichuan, Chongqing and Jiangxi. Zhejiang, Guangxi, Sichuan, Chongqing, and Jiangxi have a small planting scale and have only been introduced in recent years. The scale and quantity of cultivation are small.

The vines are planted for several years to bear fruit.

After planting, the grapes can bear fruit after 2-3 years of maintenance, and there are certain differences between different varieties. For example, Jufeng grape seedlings generally bear fruit after 2 years of maintenance, while Lanyu grape seedlings take 3 years to bear fruit. The grapes are grown on fertile land that is ventilated, sunny and well-drained.

In northern China, they are mostly planted in spring, in mid to late April. Before planting, use a sharp tool to clean the bandage outside the marriage interface, pour enough planting water, and then bury the fine soil to moisturize and dry it to make it germinate early.

Grafted vines blossom and bear fruit.

The seedlings can be grafted and propagated on their own, from mid-May to mid-June. You can also buy grafted grape seedlings cultivated in the seedling base for planting. Grafted vine seedlings, if well managed in the first year and with sufficient fertilizer and water, will form flower buds and bear fruit in the second year.

If it is not well managed, the result time may be delayed. From 2010 to 2010, a vine was planted in the spring and it bore fruit in one year. Plant a pot on the balcony and knot 90 bunches in autumn.

If you plant it in summer or autumn, it will bear fruit the next year. If your potted grapes still don't bear fruit after two years, you can cut off all the old branches without fear that they won't grow.

Potted vines bear fruit.

The reason why the vines do not bear fruit can be that the reins are planted with female flower varieties and cannot pollinate and fertilize themselves, so they cannot bear fruit. In addition, if the branches and leaves are not pruned in time during the growth period, the branches will overgrow and have poor light transmittance, which is not conducive to the formation of flower buds and fruit set. If the flowering period encounters a rainy day, it will also affect pollination, fertilization, and fruit set.

Why don't the vines bear fruit.

1.If you want your vines to grow better, you should choose better quality soil to grow on. First of all, the soil must be fertile, which is the basis for fruit trees to take root and sprout quickly.

Secondly, the soil must have good water and fertilizer retention capacity, which is conducive to the vigorous growth of fruit trees in the later stage. 2.When watering, be sure to control the dryness and wetness of the soil.

If the soil is dry, water it promptly. If the soil is not dry, do not water it again. During the growth period of fruit trees, the water demand is relatively large, so they should be replenished in time.

However, when the fruit tree bears fruit, we must reduce the amount of watering appropriately, otherwise, the fruit tree yield will decrease. 3.During the fruit-setting and fruit-bearing period of the fruit tree, it is best to fertilize it every 20 days or so.

If you use chemical fertilizer, it is recommended not to use compound fertilizer, but to replace it with organic fertilizer, so that the grapes will have a better taste and higher nutritional value.

Summary. The vine is botanically a shrub with an average lifespan of about 60 years, depending on the variety, region, climate and human care. Usually a new vine is not harvested until the third year after it is planted.

Hello, I have seen your question and am sorting out the answer, please wait a while Grapevines are a type of shrub in botany, and the average lifespan of the vine is about 60 years, depending on the variety and region, climate and human care factors. Usually a new vine is planted and the harvest does not begin until the third year after it has been planted and used for winemaking. acres.

Hello, there are several reasons:

1. Breed problem.

Some grapes may be planted with female flower varieties, which cannot be pollinated and fertilized normally, and naturally cannot bear fruit, such as the common mosaic white chicken heart, black chicken heart, Lanzhou big grape, Anjiwen and so on in the northwest region.

2. Management issues.

Sometimes the grapes we grow at home have enough water and fertilizer, and the vines are growing vigorously, but we don't know how to prune them, and we think that the more they grow, the better they learn, which is actually a wrong idea.

The vine has long branches, which will block the inner branches, and the branches and buds will not absorb sunlight, and the maturity will be very poor, which is not conducive to flower bud differentiation and fruiting.

3. Environmental issues.

When the nutrients and water are sufficient during the flowering period, if the flowering period encounters adverse climate change, such as continuous cloudy and rainy days, persistent high temperatures and droughts, it will affect the pollination, fertilization and fruiting of the vines.

Solution. If the vines do not have enough light, they should be ventilated, prune the fruit trees more, and increase the light.

If it is a fertilization problem, it should be noted that nitrogen fertilizer should be stopped before flowering, and it is necessary to focus on basal fertilizer, and chase more water-soluble fertilizers in Haihai and Weihai, especially potassium fertilizers.

If there is no problem with the variety, pay attention to the environment and management, generally prune once in winter and once in summer, and do not be lazy, and only prune once a year.

With proper management, vines around 50 years old can still produce grapes. The main reasons for the failure of the vines planted in the courtyard are: the lack of timely pest control in summer and autumn, the leaves fall off in advance or are eaten by pests, the tree body stores insufficient nutrients, and the flower buds are not well differentiated or undifferentiated flower buds, so it is not easy to bear fruit.

For fruit trees to be productive, leaf preservation is the key.

Countermeasures and suggestions: Spray fungicides such as Bordeaux liquid, methyl tobuzin, mancozeb and other fungicides from early June, and spray them every 10 days or so to prevent downy mildew; Spray insecticides such as cypermethrin and phosphine emulsifiable concentrate to control leaf-eating pests such as beetle.
