The peach tree has yellowish leaves and many holes

Peach trees have yellow leaf loss of green, and the typical symptoms are: young leaves lose green, and the veins turn gray-green, yellow or white, and the leaf veins remain green. The reason for this is mainly due to iron deficiency in the tree.

In the production management of peach trees, there are many factors that affect the absorption of iron, mainly the following:

Insufficient oxygen in the soil. The root respiration of peach trees is more active, if the peach tree is planted in a more sticky or compacted soil, the soil is not loose and the air permeability is poor, which will cause a lack of oxygen, and the root system of the peach tree will be blocked due to respiration, resulting in yellowing of the leaves.

When peach trees have too much water in the early stages of growth, it can also cause difficulty breathing in the root system.

The soil is too salty. Peach trees planted in heavy saline land often have yellowing leaves.

Applying too much nitrogen or phosphorus fertilizer can also affect the absorption of iron by peach trees, resulting in yellowing of leaves.

Overweight pruning. In winter, excessive thinning of large branches and imbalance of root-shoot ratio can also cause yellowing of peach leaves.

The root system is damaged by pests and diseases or applied to unrotted organic fertilizer. Some peach orchards are applied with unrotted organic fertilizer or uneven fertilization, and the fertilizer is applied directly to the root system and the root system is burned out, causing the peach leaves to turn yellow.

The methods to solve and control yellow leaf disease of peach trees are:

Check whether there is a lack of iron in the soil, if there is indeed a lack of iron in the soil, an appropriate amount of ferrous sulfate can be applied to supplement; If iron deficiency is not present, the influence of human factors should be considered.

Find out the cause of iron deficiency in the tree. According to the above factors that affect iron absorption, find out what causes iron deficiency yellow leaf disease, so as to treat the symptoms**.

Increasing the application of organic fertilizer and liquid fertilizer, completely changing the soil structure, and increasing soil organic matter are the most fundamental methods and effective measures for the prevention and control of yellow leaf disease of peach trees. (This is an excerpt from it).

I thought, "As for the holes in the peach leaves, the reason for the holes is that your peach trees attract insects, and usually insects eat the leaves." Just take some pills. ”

Yellowing of peach trees? These three common reasons should be understood by growers! Peach trees are planted with yellowish leaves.

Yellowing of peach trees? These three common reasons should be understood by growers! Peach trees are planted with yellowish leaves.

Hello, peach tree yellow leaves should pay attention to several problems, the first can not apply unrotted organic fertilizer, like chicken manure will have a large amount of ammonia will burn the capillary roots, affecting the development of peach tree roots, can be used after rotting, or use organic biological fertilizer, bacterial fertilizer to improve the soil, increase the content of soil organic matter to prevent the occurrence of peach tree yellow leaves.

Second, it is necessary to prevent the physiological deficiency of peach trees, supplement trace elements, magnesium, iron supplementation, usually iron deficiency will directly lead to leaf yellowing, when supplementing iron, we usually apply ferrous sulfate through the roots, it is recommended to also use chelated iron (relatively stable), ferrous sulfate (alum) is easy to be oxidized, the validity period is short, and the effect on the prevention and control of peach yellow leaves is not ideal.

Don't worry about the yellowing of the leaves of the peach tree, this is a symptom of magnesium deficiency, iron deficiency and zinc deficiency, and the following will teach you how to prevent and treat it.

Hello The leaves of the peach tree are yellow and have many holes, there are several possibilities: iron yellow leaves, peach trees show symptoms of greening, yellowing or albinism, detect the soil into acorn, fertilize and supplement iron. 2.

Excessive soil moisture, poor air permeability, and excessive stickiness of compaction or soil macrobending cause insufficient oxygen in the soil and obstruction of peach tree root respiration, resulting in yellow leaves. 3.Fertilization that is too close to the tree, too much, or the application of unrotted farmhouse manure will cause fertilizer damage, resulting in the loss of some or all of the root absorption function, resulting in yellowing of leaves or dead trees.

4.The salt content of the soil is too high, and the saline-alkali metro elements are easily solidified by the soil and cannot be absorbed and utilized by the root system. We hope you find it helpful.

Summary. The yellowing of the edges of the leaves of the peach tree is mainly caused by the following points:

1. Excessive pruning.

A large number of green leaves and branches are cut off, resulting in the sudden loss of a large number of nutrient-producing leaves, and the respiration, photosynthesis, and transpiration are seriously weakened. At the same time, the ability of the root system to absorb nutrients also decreased sharply, and the nutrients were seriously insufficient, which in turn caused the phenomenon of yellowing of leaves.

2. Lack of oxygen in the root system.

The root respiration of peach trees is relatively active, and the soil is saturated, seriously compacted, and has poor air permeability during the growth period, which will cause insufficient oxygen, and the root system will be blocked due to respiration, resulting in yellowing of leaves.

3. Peach trees lack iron.

The green color of the leaves is mainly the color of chlorophyll, and the synthesis of chlorophyll must have the participation of iron, if the iron is deficient, the chlorophyll synthesis is hindered, and the leaves are yellowed.

4. Wrong fertilization.

Excessive application of nitrogen or phosphate fertilizers can also affect the absorption of iron by peach trees, resulting in yellowing of leaves. There are also peach orchards that are not ripe for application of organic fertilizer or uneven fertilization, which damages and burns the roots, causing the leaves of peach trees to turn yellow.

5. Pests and diseases.

Some peach trees suffer from root cancer, root rot, gum disease, root-knot nematodes and other root diseases and pests, which weaken the tree, affect the growth of the root system, destroy the root system's ability to absorb nutrients, and what to do if the edge of the peach tree leaves is yellow.

Hello. The yellowing of the leaf edges of peach trees is mainly caused by the following points: 1. Excessive pruning cuts off a large number of green leaves and branches, resulting in the sudden loss of the leaves that produce nutrients from the base of the tree, and the respiration, photosynthesis, and transpiration are seriously weakened.

At the same time, the ability of the root system to absorb nutrients also decreased sharply, and the nutrients were seriously insufficient, which in turn caused the phenomenon of yellowing of leaves. 2. The root system is hypoxic and the root of the peach tree is more active in respiration, and the soil moisture saturation, serious compaction and poor air permeability during the growth period will cause insufficient oxygen, and the root system will be hindered by respiration, which will cause the leaves to turn yellow. 3. The green color of the iron deficiency leaves of peach trees mainly presents the color of chlorophyll, and the synthesis of chlorophyll must have the participation of iron.

4. Wrong fertilization of nitrogen fertilizer or excessive application of phosphorus fertilizer will also affect the absorption of iron by peach trees, resulting in yellowing of leaves. There are also peach orchards that are not ripe for application of organic fertilizer or uneven fertilization, which damages and burns the roots, causing the leaves of peach trees to turn yellow. 5. Pests and diseasesSome peach trees suffer from root cancer, root rot, gum disease, root-knot nematode and other root diseases and pests, which weaken the tree potential, affect the growth of the root system, and destroy the root system's ability to absorb nutrients

Yellowing of the leaves of the peach tree may be due to a lack of light.

Peach trees love light and need plenty of light during the growing period to promote the growth of branches and leaves. Insufficient light during the maintenance period, the peach tree lacks light and cannot carry out photosynthesis, accumulate nutrients, and cannot promote the formation of chlorophyll, and the leaves will gradually turn yellow in the later stage.

The yellowing of the leaves of the peach tree not only requires a certain amount of light time. At the same time, during the growth period, the peach tree needs to have sufficient water to promote the growth of flowers and leaves. Insufficient moisture or dry weather during the maintenance period will cause the peach tree to grow poorly.

The peach tree lacks water, the branches and leaves cannot grow normally, the leaves will dry up and turn yellow or fall off, the growth of the peach tree will deteriorate, and the branches and leaves will not grow normally. Peach trees lack fertilizer for a long time, and the leaves will turn yellow and wilt.

The solution to the yellowing of the leaves of the peach tree

Trim properly. The first pruning amount of early-maturing peach after fruit picking should be light, as long as the peripheral and upper parts of the individual branches that affect the light are removed, and the inner light can be improved, and the pruning amount should not exceed 10% of the total number of branches of the whole tree. If the tree is not well controlled, it can be pruned with key leaf lifting 30 days before the defoliation.

Scientific water and fertilizer. Irrigation should not be flooded with water throughout the garden, irrigation between the rows and between the plants should be alternated, the first irrigation between the rows is not irrigated, the next irrigation between the rows is not irrigated. At the same time, it should be noted that after irrigating or after heavy rainfall, the soil is loosened to enhance soil permeability.

In terms of fertilization, it can increase the application of decomposed farmhouse fertilizer, such as circle fertilizer, manure, manure, green manure, etc., to increase the content of soil organic matter and improve the physical and chemical properties of the soil. Most farmyard fertilizers are slightly acidic, which can improve alkaline soils and reduce soil iron fixation.

1.When the leaves of the peach tree appear yellow, it may be caused by insufficient light, it is recommended to place it in a sunny environment to breed, if it is not properly watered and the leaves are yellow, you need to cut off the rotten roots and replant, if there is a lack of water, but also to water it appropriately. 2.

Iron deficiency causes leaves to turn yellow, the green color of leaves is mainly the color of chlorophyll, the synthesis of chlorophyll must have the participation of iron, if iron is deficient, the synthesis of chlorophyll is blocked, and the leaves are yellowed. 3.Root disease, toxic substances or root pests and diseases will affect the growth of the root system, destroy the ability of the root system to absorb nutrients, resulting in insufficient nutrients and yellowing of leaves.
