Are 15 year old vines too old?

15 years old vines.

A vine can continue to produce grapes for up to 120 years, but after the vine is 30 years old, the optimal age is 5-6 years, the yield gradually decreases, and the bunches gradually become smaller.

The yield of old vines is only 1 10 or even less than that of young vines, but the quality of the grapes is improving, and the nutrients are concentrated in small grapes, which make the flavor more intense and rich, and the quality is better.

How grapes are grown.

1. Soil. The vines are suitable for growing in loose soils, breathable and water-retaining soils, and highly fertile soils, and can be cultivated in a ratio of 4:3:3 with humus, pastoral soil and coarse sand.

It can also be configured with garden soil, coarse sand, and puffed chicken manure in a ratio of 7:2:1. Once the soil is ready, the vines can be planted and can be potted.

It can also be planted in the ground.

2. Illumination. The vine likes to grow in the sun, and allowing the vine to receive sufficient sunlight can encourage the vine to grow better and produce delicious fruit. If there is no sunlight, the vines will not grow well and the fruit will be less tasty.

However, in summer, you need to protect it from the sun with shade nets to avoid sunburn.

3. Water and fertilizer. After planting, the vines should be watered every 7-10 days, and in case of heavy rain, pay attention to drainage, water a lot in the early stage of growth, and water a little water in the later stage of growth.

The fruit should not be watered during the coloring period, and it should not be watered with light water before harvest or in the morning. Apply an appropriate amount of compound fertilizer every time you water.

Spray foliar fertilizer every half month.

8-year-old vines are not old, often too young less than 3 years old vines are difficult to produce grapes, to 10-15 years is the first period, the yield is also the largest, so 8 years of vine growth is still a good period, there are still three or four years of vines in the breeding.

There are many excellent varieties of grapes, and the fresh food varieties suitable for cultivation in Northeast China include Jufeng, Tengnian, Jingxiu, Meirenzhi, Ruby, Honey, Hutai No. 8 in Shaanxi, and grapes in Turpan, Xinjiang.

Grapes are planted in well-ventilated, sunny and well-drained fertile land, and spring planting is mostly used in northern China, and field planting can be carried out in mid to late April. The planted seedlings are buried in the soil to the root neck and watered enough planting water, and then the seedlings are buried in a small mound of soil to moisturize and prevent drying, so that they can germinate early.

Field Management:

Cultivating is soil tillage carried out during the grape growing season, and its function is to keep the soil loose, improve aeration conditions, prevent soil moisture evaporation, and promote microbial activity;

Increase available nutrients and reduce pests and diseases. Saline land can also reduce salinity rise and maintain soil moisture and fertility. Cultivating and weeding is in the season of vigorous root activity, in order to prevent root damage, cultivation should be shallow, generally 3-4 cm.

After irrigation or rainfall, the soil should be loosened in time to prevent soil compaction and water evaporation. Cultivating 6-8 times a year is sufficient. Removing weeds from the vineyard during the growing season is an important management task and should be combined with tillage and weeding. The combination of chemical weeding and manual weeding has a good effect.

I still often miss the old vine in my yard a long time ago.

By the time I was in junior high school, a large trellis had formed in the yard, and they accompanied me throughout my childhood until I reached adulthood. So much so that later, no matter how much I saw the vines in **, there was a sense of intimacy. However, because the family rebuilt the house, they were sawed off by my father one by one.

At that time, I went home once a week, and after school, I was distressed and helpless.

There was only one left, and it was in its twenties at that time, older than me. It probably anticipated its final fate, and I remember it vividly, and in its final years, it produced surprisingly high volumes. Under the proper pruning of the mother's branches, it can be fruitful, but after exerting all its strength, it will take a year off to be productive again.

Every year, in addition to being enjoyed by our whole family (mainly my sister and me), it also has to take care of the children and their parents who come to my house to "cool off" during the harvest season every year.

My mother said that when I was a child, whenever she was busy with farm work and I was crying, she would pick a spoonful of grapes, and then I would sit there obediently and eat by myself for a long time. At that time, the well water in the pressurized water well was still cool, and the soaked grapes were also cool, and I can still taste the taste of the grapes now.

In the end, when building a new building, it was sawed by my father. I really regret that I didn't learn the relevant knowledge of tree transplanting at that time, and there was nothing I could do about its "hindrance", so I watched my father cut it hard. Although my mother later said that there were already worms in the trunk of the tree, and most of the trunk was rotten, and if I didn't saw it, I was afraid that it wouldn't live long.

However, it is still distressing.

A few days ago, I suddenly found that a kind of local grape in Suzhou tasted like the fruit of an old tree, and the aunt of the fruit shop said that it was fresh. I just smiled and didn't speak, you don't necessarily know more about grapes than me, so I decisively bought two bunches to satisfy my cravings. Well, it's delicious, but unfortunately there is a lot of fermented alcohol, but I just think the grapes that don't bear the fruit of the old vines are delicious.

A bowl of respect for you, a bowl of respect for the old tree.

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.
