Why do walnut trees dry down, and how do walnut branches dry in the shade?

First, the natural rotten book is dry.

Healthy and disease-free, pest-free, walnut with intact epidermis, after a few days of natural shade drying, the epidermis appears wrinkled and shriveled, and the green skin will naturally separate from the nut, but the injured walnut, the green skin has been blackened locally, this method is not applicable, and the service will cause pubic skin.

2. Artificial peeling.

Specific steps: Use a knife to peel off the large pieces of green skin, combine it with water and continue to brush the remaining residual green skin with an iron brush, and finally carefully clean it with a fine needle and toothbrush. The whole process is best carried out with rubber gloves, otherwise the ** on the hands will be stained black.

In addition, it should be noted that do not let the juice of the green skin splash to other **, otherwise it will fester, because the green skin of walnuts is also called "Qinglongyi Hunger Talk", and its juice is highly toxic. Don't splash it in your eyes.

The biggest advantage of manually peeling the green skin is that the skin color is good-looking, and the walnut skin that is naturally separated from the bones is dark.

1.Why don't walnut trees bear walnuts?

As a common fruit tree, many people encounter such a question when planting walnut trees: why is the tree quite big, but it does not bear walnuts? In fact, there are many reasons why walnut trees don't bear walnuts, so let's find out together.

2.Walnut trees need plenty of sunlight and moisture.

During the growth of walnut trees, adequate sunlight and water are very important conditions. If the walnut tree lacks light or water, it will affect the growth of its fruit. Therefore, when planting walnut trees, it is necessary to choose to grow in an environment with sufficient light and water, so as to ensure that walnut trees can bear fruit smoothly.

3.Walnut trees need the right temperature and climatic conditions.

The temperature and climatic conditions required for walnut trees to grow are relatively harsh. In general, the suitable temperature for walnut trees is between 15 and 25 degrees, with a minimum temperature of not less than -10 degrees. In addition, walnut trees also need adequate rain**, and generally speaking, areas with annual rainfall of more than 900 mm are more suitable for growing walnut trees.

4.Walnut trees need the right amount of fertilization and maintenance.

Walnut trees need the right amount of fertilization and maintenance during their growth. Embedding the right amount of organic or compound fertilizer around the trunk of a tree can not only provide nutrients, but also improve the soil environment and maintain adequate moisture. In addition, during the growth of walnut trees, it is also necessary to prune the branches in time to maintain the light transmission of the crown and promote the growth and development of the fruit.

5.Epilogue.

Overall, the reasons why walnut trees don't bear walnuts can be manifold. If we want the walnut tree to produce more fruits, then we need to create a good growing environment, suitable temperature and climatic conditions, adequate light and moisture, and the right amount of fertilization and maintenance. Only in this way can the walnut tree smoothly produce delicious fruits.

Summary. Hello, one is that the nutrients are not absorbed, and the other is that if the walnuts on the walnut tree are too dense, it is also a burden on the tree.

Hello, one is that the nutrients are not absorbed, and the other is that if the walnuts on the walnut tree are too dense, it is also a burden on the tree.

Hello, 1, mostly due to incomplete fertilization, the development of the embryo is stunted, the young fruit lacks the hormone of the embryo **limb hole, or due to the rainy weather during the flowering period, affecting the wisdom of the pollen, or the lack of oxygen during the flowering period, the young embryo lacks protein **, stops developing, can cause fruit drop. Control measures: Spraying Zhuangguo Diling solution at the bud stage can thicken the fruit pedicle, improve the amount of nutrient delivery, and prevent flower and fruit drop.

For varieties that lack pollination, pollinators should be equipped with green trees, or orchard bees and artificial pollination should be used.

2. In the process of development, the young fruit that has been fertilized will fall due to the cessation of development in the middle of the embryo. At the time when the embryo and the new shoot are in vigorous growth and need a large amount of nitrogen, due to the lack of nitrogen, or the excessive weight of the new shoot to grow too vigorously, it takes away the nutrients needed for fruit development, resulting in the lack of nutrition in the embryo, stops developing and falls the fruit. Prevention and control measures:

In the young fruit stage and fruit expansion stage, spray the strong fruit tiling solution to prevent fruit dropping, cracking, stiff fruit and deformed fruit, so that the fruit is beautiful in color, beautiful in fruit shape and good in taste. It should focus on the appropriate supply of fertilizer and water before the hard core, and adjust the use of nitrogen fertilizer. In the rainy season, timely drainage should be carried out to prevent water accumulation in the orchard, timely soil management should be carried out, and root growth conditions should be improved; Through summer pruning, the branches are prevented from growing, the light conditions in the canopy are improved, and the photosynthetic capacity of the leaves is improved. In addition, attention should be paid to the control of pests and diseases to prevent early defoliation.

Here's the official terminology.

Satisfied, thank you.

The trunk and leaves of walnut trees are basically caused by two diseases, which should be prevented in advance and actively **.

In July and August, walnut trees have dry leaves, and the main reason is generally fungal charcoal: gangrene, and sometimes bacterial black spot occurs at the same time or separately.

Walnut, also known as walnut and Qiang peach, is a plant of the Juglans family.

Together with almonds, cashews, and hazelnuts, it is known as the world's famous "four dried fruits".

Walnut kernels are rich in nutrients, containing 15 20 grams of protein per 100 grams, more fat, and 10 grams of carbohydrates; It also contains a variety of trace elements and minerals such as calcium, phosphorus, and iron, as well as carotene, riboflavin and other vitamins. It is good for the human body and strengthens the brain. It is one of the nut foods loved by the people.

It is known as "Long Live Son" and "Longevity Fruit".

Because the walnut plant grows weakly, some compound fertilizer can be sprinkled in autumn to make the plant grow more vigorously and reduce the shedding of walnuts; Physiological disorders cause flower and fruit drop, which is generally caused by lack of fertilizer or lack of trace elements, so fertilization is very important.

In the early stage, nitrogen fertilizer was mainly applied, pecan fruit stabilization fertilizer was applied early, and 300 times of forest fruit enhancer was used at the end of May and early June, and long-acting insecticides, such as imidacloprid, were added.

Foliar spraying of pestiles such as chlorpyrifos on pecans has the following benefits: it can control the physiological fruit drop of pecans; It can control the larvae of more than 10 kinds of pests such as the trunk, branches, young fruits and leaves of pecans, and eliminate them at the initial stage; It prevents a large amount of fruit drop caused by the rainy season.

It could be due to the following reasons:

1.Saplings have cuts, or wounds.

2.When planting, it was not watered thoroughly.

3. The root system is underdeveloped.

Precautions for buying walnut seedlings:

When purchasing, be sure to choose a real grafted seedling. Usually, walnut seedlings can be divided into the following varieties:

A seedlings: including seedlings with the cost of knife carving, this kind of seedlings bear fruit late, 5-8 years of fruiting, low yield, poor quality, thick shell, low commodity value, almost no production value.

b The so-called original seedlings: In fact, they are the seedlings of early-fruiting thin-skinned walnuts. Most of these walnut seedlings can bear fruit in the second year or even in the same year, and the yield is also good, but the quality, tree size, and fruit appearance are separated and differentiated. The value of the goods is low.

c True grafted walnut seedlings:

Walnut is a tree species that is difficult to graft and breed, so the number of grafted seedlings is relatively small, and it is also more expensive. Now there are also some unruly seedling breeders, who use knives to carve wounds on the seedlings and pretend to be grafted seedlings, at a low price, causing certain economic losses to the fruit farmers who are greedy for convenience.

The difference between grafted seedlings and solid seedlings:

The most obvious feature of grafted walnut seedlings is that they have "grafting marks", that is, the scars caused by grafting between the rootstock and the variety, the "grafting marks" and "V" types of "splitting", and the "grafting marks" and "mouth" types of "bud grafting". The most difficult to identify is the seedlings that sprout when the seeds germinate, but there are fewer such seedlings, so it is recommended to choose clear seedlings. It is important to note that:

Some unscrupulous businessmen are driven by profits, and use the method of direct knife carving on the rootstock to create "graft marks" to fool the fruit farmers, and even in order to prevent legal liability caused by variety problems, the root system of walnut seedlings is soaked in salt water to make it unable to live walnut seedlings.

I guess it's not a disease, the saplings you bought are not fresh enough.

Cut off the dry part, which is the phenomenon of walnut seedling.

Did the sapling have a cut, or a wound? Was it watered thoroughly when planting? What about the root system?

Walnuts that are commonly eaten are sun-dried; The walnuts are dried.

1. Edible walnuts will inevitably be knocked when peeling and cleaning, which is the walnut kernel will inevitably enter the water, if it is easy to let the walnut kernel and the epidermis mold affect the first and eat, so it must be placed in a sunny place for drying.

Second, the walnut is mainly used in the place where walnuts are wooden, so they cannot be directly dried in the sun. Walnuts should be dried in a cool place, not air-dried or sun-dried, because this will crack the walnut shell and affect the market value in the later stage.

Fresh walnuts have a layer of green skin wrapped outside, if you are not in a hurry, you can put it in a cool place, slowly dry in the shade, so that you can easily peel off the skin, if you want to eat it immediately, you can use a knife to peel off the green skin outside, at this time it is best to wear gloves to avoid the juice on the hands, it is more difficult to clean, the method of walnut preservation is relatively simple, put it in a ventilated and cool place.

The production of walnuts is to fully dry the walnuts in a sack or cloth bag with good air permeability, put in a cool, dry and ventilated place, if you want to store for a longer time, you can also store the dried walnuts in a sack in a cold storage filled with carbon dioxide gas, which can be well stored for more than one year. The optimal temperature for indoor storage of walnuts is 1-2, generally not more than 8, and the relative temperature is 75-80.

I have a lot of walnuts in my house. After the walnut city molts, it is washed clean with water and dried in the sun on a sunny day! Sometimes the inside will break if it is dry!

Air-dried. If you put it in a dark and damp place, it will be moldy, and it will be too dry and fragrant in the sun. Keep it out of light and in a ventilated place.
