Why are the branches of kiwi fruit Peng large period yellow?

Let's take a look at what kind of yellowing state the branches are in. If the young branches turn yellow, the fruit will not grow very solid, but will swell inside. The yellowing of the leaves may be due to a lack of nutrients such as zinc, iron, copper, etc.

It can also be caused by too much drought. This year has been very dry in both Northwest and North China. Water in time during the bulking period of young fruits.

Appropriate adjustments can be made during the fertilization process. In addition to nitrogen, phosphorus and potassium fertilizers, phosphorus, calcium, potassium and boron fertilizers must also be supplemented at the young fruit stage to promote fruit greening and rapid expansion. Calcium supplementation micro-energy, strong roots and trees, fruit expansion and strong fruits, foliar calcium supplementation and micro-boron, good surface gloss, green and beautiful young fruits.

If newly planted kiwifruit seedlings are not properly managed, the branches will soon wither and die. What is the reason for this?

The basal fertilizer applied before planting is not fully fermented and decomposed, and the seedlings are damaged due to root burning in contact with the root system during the planting process. 2.During the germination and branching stages after field planting, fertilization is applied too early, too intensively, and too frequently to dehydrate and kill the newly-born young new roots.

3.The planting area is low-lying and has long periods of water accumulation, leading to root rot and death.

Prevention method: The basal fertilizer applied before planting should be fully fermented and decomposed, and should not be in contact with the root system of planted seedlings. Fertilization at the seedling stage should be thin and moderate.

The planting area should be selected in a high cool area with easy irrigation and drainage. There are many other reasons why kiwi leaves turn yellow. Due to the thin and brittle leaves, large leaf area, high summer temperature, and long-term exposure to sunlight, the leaves are prone to drying, curling and yellowing, and even cause sunburn of the leaves and fruits, reduce photosynthesis, and affect fruit yield and quality.

Long-term diseases can also cause the entire tree to turn yellow or even die, causing a lot of losses to the grower. At the same time, old trees, that is, trees with a lot of fruit last year, poor soil permeability, malnutrition, tree weakness caused by disease and root-knot nematodes are the causes of yellowing of kiwifruit leaves, and should be prevented and controlled in time after discovery.

There may be some problems with the soil, so you can sprinkle some phosphate fertilizer appropriately.

This is mainly due to the fact that fruit trees are affected by the fruit, so the branches are undernourished.

In this case, it may be that the nutrition has been mixed with a certain amount, which is why it is like this.

The main reason may be that it is due to tree branches.

It is worth noting that during fruit enlargement, 60% yellowed due to fertilization。During the application of chemical fertilizers, there is too much potassium in chemical fertilizers. The inhibitory effect of excess potassium on nitrogen leads to the fact that nitrogen does not participate in the photosynthesis of leaves and inhibits the absorption of magnesium, calcium and iron by leaves.

This is what causes the branch to turn yellow.

Excessive fertilization can also cause root burns. If the roots burn in large quantities, the nutrients cannot be absorbed to provide the development of the branches, which will also cause the branches to be yellowish in color. Pests and insects, plants that fill the orchard can also damage the roots and branches, and can also cause yellowing of the branches, but considering that it is during the expansion of the fruit, it is more likely to belong to the first, and the yellowing of the branches is caused by improper fertilization.

In this sense, fruit farmers should pay attention to scientific fertilization and reasonable fertilization to ensure the quality of their fruits, so as to achieve the purpose of increasing yield.

Usually, the yellowing of kiwifruit leaves caused by pests and diseases is rare. The main pests are usually spiders. If this happens, the kiwi infestation is already very worrying.

During the entire process of kiwifruit cultivation, yellow leaf litter caused by kiwifruit leaf invasion is most likely to occur. Due to the multiple diseases of kiwifruit, its hazards are also different. Kiwi diseases are usually dusty molds, gray molds, brown spots, anthrax, and viral diseases.

Sometimes kiwis can have several diseases at the same time.

The soil is heavily compacted, resulting in poor ventilation, too high temperature and humidity, and the roots of the kiwi are in a moist soil environment. It is easy to mess up the roots and necrosis, causing the upper part to provide nutrients, causing the branches to turn yellow. Drop the leaves.

The soil quality of kiwi orchards can deteriorate, such as changes in acid or alkali (e.g., long-term application of acid fertilizers or long-term use of quicklime to disinfect kiwi orchards, etc.) may lead to changes in the pH of the soil.

Hello, yellowing of new leaves of kiwi trees can be caused by a variety of factors, here are some possible causes and solutions:1Soil Issues:

Kiwifruit prefers acidic soil, and if the soil is too alkaline, it will affect the absorption capacity of kiwifruit, causing new leaves to turn yellow. At this time, sulfur or acidic fertilizers can be added to the soil to make the soil more acidic. 2.

Insufficient nutrients: If the kiwifruit lacks nutrients such as nitrogen, phosphorus, and potassium, it will also cause the new leaves to turn yellow. Kiwifruit can be fertilized, especially during the growing season and in the early stages of fruit ripening, and the amount of fertilizer should be increased.

3.Pests and diseases: Kiwifruit is susceptible to pests such as aphids, whiteflies, and spider spiders, and may also suffer from diseases such as anthracnose and powdery mildew.

These will make the new leaves of the kiwi yellow. Timely control measures such as spraying pesticides or pesticides need to be taken. 4.

Light problems: Kiwis prefer full sun exposure, and if the ambient light is not enough or direct sunlight is too strong, it can also cause the new leaves of kiwifruit to turn yellow. At this point, the location of the kiwifruit planting can be changed or appropriate shading measures can be taken.

To sum up, in order to solve the problem of new leaves of kiwifruit changing to yellow, it is necessary to determine the cause and then take corresponding measures in a targeted manner. If the problem is more serious, you can ask a professional gardener to check it and**. Dear, I'm glad to answer for you.

The above is mine, I hope mine can help you, if there is anything you don't understand, please feel free to ask again. Thank you!

Summary. The soil temperature is generally higher than 8, and the kiwifruit root system can start to move, so it is necessary to supplement the kiwifruit with nutrients in time.

Kiwi tree also because of the influence of high temperature weather, branch buds in advance of bud breaking, resulting in the reserved fruit on the mother branch, extracted a lot of short weak branches, each branch is not long, the general length is within 15 cm, the branch is short and weak, not only consumes the nutrient accumulation of kiwifruit, but also seriously affects the germination rate and flowering rate of this year's kiwi tree. 2, kiwifruit empty branch situation kiwifruit due to the influence of last year's high temperature, resulting in the differentiation of flower buds is not complete, this year kiwifruit began to draw new branches, there are many new branches without flower buds, these flowerless branches are not lucky, if not as the next year's results of the basal mother branch retained, can only be erased, resulting in some kiwifruit fruit mother branches will appear long sections of no branches without fruit empty rod phenomenon. 3. Kiwifruit fruit mother branch bud stuffy withering and dying This year, many fruit farmers are saying whether their kiwifruit has a stuffy bud, and the buds on the branches have not been extracted, resulting in a large section of the branch on the smooth rod, I don't know what the reason is.

In fact, the occurrence of this kind of stuffy bud situation is not directly related to this year's management, it is all caused by the natural weather of the previous year, but the fruit farmers did not observe carefully. The buds of kiwi are generally not easy to distinguish, except that the buds are more intuitive to extract new branches, the appearance and shape of the buds are basically the same, but if you observe carefully, you will find that the surface of the kiwi buds is slightly protruding, and it may have broken the buds or stuffed buds, and can not complete the tip branch extraction, but this illusion will also make people feel that there is no problem with the buds on the branches, and when the next year begins to pump, it will be found that the buds have no ability to draw and have become dead buds. This year, I thought it was a stuffy bud.

Remedies for yellowing of new sprout leaves of kiwi trees in spring: 1. Light: You can transplant the kiwi tree into an environment with sufficient light and air circulation for maintenance, and clean up the fallen leaves around it by the way.

2. Moisture: Minimize the number of watering, keep the potting soil in a dry state, and wait for the temperature to rise, so that it can slowly resume normal growth. 3. Temperature:

It is necessary to control its growth temperature and keep warm when the temperature is low. 4. If you have a tree with yellow leaf disease, you should first rinse the root system with water to see if there is root rot and root nematodes, and then use drugs respectively. It can also be compared with the root system of a healthy tree.

5. Soil environment: give the root system a healthy soil environment. Apply more bio-fungus fertilizers to form a soil rich in microflora and biodiversity.

Kiwi trees should pay attention to the inspection of the leaves, especially the back of the leaves, and cut off the diseased leaves immediately once insect pests such as spider spiders are found.

Summary. The yellowing of the spring sprout leaves of the kiwi tree can be caused by a variety of reasons, and here are some possible reasons and corresponding solutions:1

Lack of nutrients: If there is a lack of nutrients in the soil, the new sprout leaves of the kiwi tree will turn yellow. In this case, you can sprinkle organic fertilizer or fertilizer mixture under the tree to help provide enough nutrients.

2.Overwatered or over-dry: If the tree's soil is too moist or dry, the kiwi tree's new sprout leaves will turn yellow.

In this case, the frequency and amount of watering need to be adjusted and make sure that the soil does not dry out.

If there is a lack of nutrients in the soil, the new sprout leaves of the kiwi tree will turn yellow. In this case, you can sprinkle organic fertilizer or a mixture of fertilizers under the tree to help provide adequate nutrients. 2.

Late watering or too dry: If the tree's soil is too wet or dry, the kiwi tree's new sprout leaves will turn yellow. In this case, it is necessary to adjust the frequency and amount of watering and ensure that the soil does not dry out.

3.Pests and diseases: Kiwi trees can be attacked by pests and diseases, such as aphids or powdery mildew.

These problems can cause the sprout leaves to turn yellow and shrivel. In such cases, appropriate measures need to be taken to control pests and diseases. 4.

Water quality issues: If the kiwi tree grows in a water source with higher salinity, the sprout leaves may turn yellow. In this case, it is possible to consider changing the source of water knowledge or filtering salt through the irrigation system.

5.Lack of light: Kiwi trees need plenty of sunlight to grow healthy.

If the tree grows in a climate that lacks sunlight, the new sprout leaves may turn yellow. In this case, you need to consider moving the tree to a sunnier place. To sum up, it is necessary to find out the reason why the new sprout leaves of the macaque tree turn yellow according to the specific situation, and then take corresponding measures.

The yellowing phenomenon of peach is a manifestation of nutrient deficiency.

If you want kiwifruit to grow well, water and fertilizer management is essential. Do not be too close to the root system when sprinkling compound fertilizer inside, and water it in time after sprinkling fertilizer.

Burning the leaves and fruits in direct sunlight can have a big impact on kiwifruit. The fruit can be bagged before June, taking care to replenish the water.

It is caused by a variety of reasons such as nutrient deficiency, root rot, nematode disease, etc.

Drought and water shortage affect nutrient absorption, followed by the large load of fruit trees in the previous year, which weakens the tree, resulting in nutrient deficiency and yellow leaf disease. The deficiencies are mainly iron, magnesium and zinc, especially iron deficiency. Thirdly, nematode disease and root rot damage lead to the reduction of the ability of roots to absorb nutrients, resulting in dwarf plants in the aboveground part and yellowing and weakening of branches and leaves.
