How big can a walnut tree grow and how tall is a walnut tree? When do walnuts ripen?

The tree is more than 100 years old and has a diameter of more than 60cm.

One: the height of the walnut tree

The height of walnut trees is generally more than 10 meters, and the longer the walnut tree is planted, the higher the height of the tree and the higher the yield. The lifespan of walnut trees is very long, and it can reach hundreds of years, and walnut trees that reach hundreds of years can still maintain a high yield.

Two: the planting of walnut trees

Walnut trees should be planted in fertile soil, with plenty of light, in deep soil, and with good drainage, preferably on sunny slopes and leeward out. During the growth period of walnut trees, it is necessary to prune the belt without a certain amount of pruning, and keep the branch height above 3m. When the walnut tree begins to lose its leaves, it is not allowed to prune, otherwise it is easy to cause damage and affect the growth of the tree.

Three: the ripening time of walnuts

The ripening period of walnuts will vary depending on the variety of walnuts and will also be affected by climatic conditions, in general, in the northern regions.

The book was written in early to mid-September, in the southern region.

It is relatively early, and it can be picked in late August. Walnut kernels are yellowish-brown in color, and some are light brown.

Four: the nutritional value of walnuts

1. It can make our hair black and shiny, because walnuts are rich in vitamin B2

Vitamin B6 and vitamin E

These are closely related to hair, and regular consumption can make our hair black and shiny.

2.Eating walnuts can replenish the brain, make us smarter, and thus improve the efficiency of the brain.

The benefits are self-evident for us.

3.Laxative detoxification, slimmer, walnuts can also ** constipation, which is rich in walnut oil.

and crude fiber, which can moisten the intestines and effectively expel stool.

Toxin. Make our figure slimmer and look better.

To sum up: walnuts can bring great benefits to our health, we should eat more walnuts in our daily life, they have a lot of effects on our body, and also have great nutritional value, planting walnuts is also a good choice, and can also be used for sale, bringing us economic benefits.

Walnut trees are generally two to 10 meters high, and walnut varieties also include walnut varieties that are sold by auctioning jujubes and selling wild pecans, and artificially grafted and improved varieties. It is ripe for harvest from late July to mid-October every year.

The height of the walnut tree is about 4 meters to about 4 meters. Walnuts generally begin to ripen from September to November, and the temperature in the south is relatively high, so the ripening time will be earlier.

1.Walnut trees are arbors that can reach up to 20-25 meters in spring; The trunk of the tree is shorter than that of other species, and the canopy is wide and wide.

2.Walnuts generally ripen in September and October, and they ripen earlier in the warmer environment of the south.

Walnut trees are able to reach a height of about 4 meters, and generally mature in autumn and in September and November.

A beam or general can reach about 10 meters. In the slag of 9 October, the walnuts need to be picked in time after they are ripe, and the trees need to be maintained.

Walnut trees can grow very tall after maturity, reaching about 10 meters, and will mature after 1 to 2 years of planting, and the growth cycle is relatively long.

Walnuts are generally ripe in 9-10 months, the warm environment in the south it collapses the yard of the ripening time will be noisy earlier, in the walnut group which ripens to harvest in time, when breeding walnuts, it needs to be regularly topdressed, to promote the vigorous growth of walnuts, dry weather to timely irrigation of walnuts, but also pay attention to the prevention and control of pests and diseases.

Walnut trees generally take 7-8 years to bloom and bear fruit.

Walnut tree planting time in late March before and after germination, planting 1 2-year-old seedlings survival rate is high, after planting should be watered thoroughly, and strengthen water and fertilizer management, often loosen soil weeding, pay attention to drainage in the rainy season, pay attention to the prevention and control of pests and diseases in June and July. Pruning should be carried out during the growth period, and the stem height should be kept above 3m. Do not prune after falling leaves, otherwise it is easy to cause damage and affect the growth of the tree.

Planting time deciduous fruit trees are generally suitable in winter, evergreen fruit trees are suitable in spring, and they should be standardized when planting to achieve horizontal and vertical rows. When planting, the grafting interface should be exposed to the ground, the root system should be extended, and then the soil should be cultivated, steadfast, irrigated, and then sealed after water infiltration, so as to facilitate water retention.

Tall walnut trees have a long lifespan, and the hundred-year-old trees can still maintain high yields. The tree is tall, thick and leafy, and the crown diameter of a large walnut tree can reach more than 10 meters, covering an area of 100 200 square meters.

Walnuts like moisture, waterlogging resistance, drought resistance, sufficient moisture is conducive to walnut production. In the year of planting, supplementary watering is required 1 2 times in the dry season. During the period when walnuts bloom and the fruit expands rapidly, the demand for water is large, and timely replenishment of water can obtain better results.

Irrigation after walnut fertilization and before freezing can improve the utilization rate of fertilizer and ensure the smooth wintering of walnuts. The surface water and groundwater level are too high to be conducive to the growth of walnuts, so if there is a rainy season in walnut production, the water in the field should be removed in time.

These walnut trees are wild and not market-bought. In other words, these walnut trees are the ones that grow through seed development, that is, seedlings.

Such walnut trees have a long growth cycle. Generally, if properly maintained, it takes more than 5 years to flower and bear fruit, and some even take about 10 years. But these walnut trees are not managed after planting, so they bear fruit very late.

When I went to my father-in-law's house last year, I found that the walnut trees were all bearing fruit.

According to my father-in-law, it has been almost 11 years since the transplant was brought to fruition. It seems that seedlings do not bear fruit easily. Even when it bears fruit, these fruits are small, have hard shells, and are very difficult to peel.

Even if I opened it, there was only a little walnut kernel inside, which was not very tasty. How many years does a walnut tree generally bear fruit? Why do walnut trees grow for three years and still don't bear fruit?

The first reason is seedlings. If it is a grafted walnut sapling, it will generally bear fruit in two or three years. And the owner of this walnut tree has been three years and has not borne any fruit.

The first reason, farmers guess that it may be the seedlings bought. Such walnut trees bear fruit late, and it takes 5-10 years after transplanting to bear fruit. So when buying walnut seedlings, be sure to buy grafted ones.

If you don't know, it's best to go to a trustworthy merchant or find a friend you know to buy it for you and avoid buying seedlings.

The second reason is the growing environment. Although walnut trees are tall, they are not strict about the growing environment. But if the planting land is too poor, and the ventilation and lighting are not good, the later management is not appropriate, there is no fertilization, no pruning, and the walnut trees are left to fend for themselves.

That's because the planting environment is not conducive to the growth of walnut trees, which delays flowering and fruiting, or even never blooms and bears fruit.

The third reason is improper water and fertilizer management. Walnut trees seem to be managed extensively, but scientific fertilization and pruning of branches and leaves can make them bear fruit earlier. After transplanting, if too much chemical fertilizer, especially nitrogen fertilizer, is applied, and the soil is moist and fertile, then the walnut tree will grow vigorously, which will affect the reproductive growth and delay the fruiting period.

But if it is not fertilized all the time, it will also affect its growth and be detrimental to the fruit. It's like growing taller and growing up. Not only do you have to eat well, but you also have to eat nutritious food.

You can't eat too much at once, you'll get fat.

In the last case, it only blooms and does not bear fruit, mainly because of poor pollination. Don't assume that just because walnut trees are male and female, walnut trees will never bear fruit. This argument is not reliable.

Walnuts are monoecious and are mainly pollinated by wind. If it rains for a long time during the flowering period of walnut trees, it will also affect their pollination, resulting in a situation where they only bloom but do not bear fruit.

In addition, there is another reason, which is caused by pests and diseases. Some pests and diseases can not only affect the growth of walnut trees, but also cause walnut trees to bear fruit, such as bud maggots. Think about it, if the walnut tree is already sick, how can you expect it to blossom and bear fruit?

So let's find out why. If it is a seedling, it can be grafted in time, but because of management reasons, it needs to be fertilized reasonably and pruned scientifically, so that the second year will almost bear fruit.

Walnut trees are hundreds of years old, more than 60 cm in diameter, about meters in height, walnut trees in summer high grafting, survival rate will be relatively high, you can carry out square bud grafting, prune too many branches, so that nutrients are more concentrated, apply nitrogen before germination, promote budding and promote branch leaf development, the later stage is mainly to apply phosphorus and potassium, selectively use herbicides, and pay attention to the application method.

The life span of walnut trees is generally about several decades, and the longevity can be about 100 years, and the third year begins to enter the harvest period, and the fifth year enters the peak production period, with an age of more than 100 years and a diameter of more than 60 cm.

How much does a walnut tree grow in a year.

Because of the different varieties of walnut trees, different environments, different management levels, so the size difference of a year can be very huge, 6 years of early walnut varieties grow 8-15 cm tall are in the normal range, 6 years of late walnut tree diameter of 12-20 cm belongs to the normal category.

How tall can a walnut tree grow.

The early walnut is smaller and more compact than the walnut crown of the late walnut, and the height of the canopy is about 10 meters if the orchard is controlled internally, and if the management is extensive, it will reach 5-6 meters, and if it is planted alone, it can also grow to about ten meters.

How to raise walnut trees to grow fast.

1. Walnut trees are afraid of pesticides and herbicides such as sweeping, so it is necessary to pay attention to the application method of herbicides when choosing to use herbicides.

2. If the walnut tree is highly grafted in summer, the survival rate will be relatively high, and the block bud grafting can be carried out, which is simple to operate, and the walnut seedling block bud grafting is the same.

3, the reputation of the repair of walnut branches, can not affect the growth of crops under the tree, too many branches absorb more nutrients, not easy to grow, thin-skinned walnuts in July, four years of walnut tree pruning, leave six branches, be sure to pinch off the secondary spike.

4. Pruning should be pushed back as far as possible after harvesting the fruit, but it must be carried out before the leaves fall to ensure the nutrients in the leaves, and pruning should be carried out according to the characteristics of different varieties.

5. The most important technology of walnut is fertilization, nitrogen is the main one before germination, urea is long branches and leaves, and the buds are promoted to promote the development of branches and leaves, and the later stage is mainly phosphorus and potassium.

Walnut trees generally live for about a few decades and about 100 years. The third year is a bumper crop, and the fifth year is hundreds of years old and more than 60 centimeters in diameter.

How much does a walnut tree grow in a year.

Due to the different varieties of walnuts, different environments, and different levels of management knowledge, the annual growth varies greatly. The height of the early-maturing walnut variety is 8-15 cm in six years, and the ground diameter of the late-maturing walnut tree is 12-20 cm in six years.

How tall can a walnut tree grow.

The canopy of early-maturing walnuts is smaller and more compact than that of late-maturing walnuts. Generally, in the case of internal control of the canopy, the height of the orchard is about meters. If the management is extensive, it will reach 5-6 meters. If planted alone, it can also grow up to ten meters.

How to raise walnut trees to grow fast.

1.Walnut trees are afraid of pesticides, herbicides and the like. Therefore, it is important to pay attention when choosing herbicides and how to use herbicides.

2.If the walnut tree is grafted in the summer, the survival rate will be higher, and square bud grafting can be performed. The operation is simple, and the square budding of walnut seedlings is the same.

3.Repair the branches of the walnut jar so that it does not affect the growth of crops under the tree. The branches are too many to absorb more nutrients, and it is not easy to grow.

Thin-skinned walnuts bear fruit in July. Walnut trees are pruned for four years, keeping six branches, and being sure to pinch off secondary spikes. 4.

Pruning should be pushed back as much as possible after the fruit is harvested, but it must be done before the leaves fall, so that the nutrients in the leaves are maintained. Pruning should be done according to the characteristics of different varieties. 5.

The most important technique for walnuts is fertilization. Before germination, nitrogen is the main body, urea grows branches to promote germination and branches and leaves, and phosphorus and potassium are the main ones in the later stage.

If the walnut tree is a seedling, the seeds are sown directly, without grafting, and it usually takes 7-8 years to produce fruit. If it is converted into grafting, it should be a stronger variety, and the later results depend on the level of cultivation management, generally 5 to 6 years. If there is no grafting confirmation, then you can transplant the detachable nipple into a tall spring variety, and after 2 years you will be able to achieve results.

It is worth mentioning that tree pruning is an effective measure to increase yield and effectiveness.

Plastic pruning: It is an important cultivation technique that makes the early fruits of walnuts ripe, rich, stable and reasonable. The pruning period of walnuts is different from that of ordinary fruit trees.

After picking the fruit, the leaves do not turn yellow, and the best way to prune them is from "white dew" to "cold dew" in northern China. Pruning at this time, the temperature is low, the wound heals slowly, but the nutrients are lost.

Small trees do not bear fruit, pruning, can start as early as the "end of the heat", before and after the general "summer", because the branches and leaves are too large, excessive nutrient consumption affects the growth of the tree.

Walnuts in the early fruiting stage should be tightly controlled on the back branches so as not to disturb the tree shape. Under the premise of not affecting the growth of backbone branches, as much as possible should be left to supplement the space and increase the early yield. The pruning method of auxiliary branches is to leave the weak behind, or to put first and then shrink, and to combine the reduction and contraction to make it as much fruit as possible, so that the growth of the long branches on the tree at the early fruit stage is particularly strong, which is easy to disturb the tree shape, and is not easy to cultivate into a fruiting branch group, which should be thinned when pruning.

For non-backbone general branches, the strong ones are thinned; The weak ones are retained to increase the vegetative area, and then gradually removed after the tree has eased. Combined with the pruning of auxiliary maintenance techniques, it is necessary to equip fruiting branch groups in a planned manner, with a large fruiting branch group of 80-100 cm for large trees, a medium-sized fruiting branch group for about 60 cm, and a small fruiting branch group for about 40 cm.
