What is the reason why the peach trees planted always bear fruit? How to fix it?

Tree shape refers to the hierarchy of the trunk of the tree and the distribution of branches and leaves, do not think that fruit trees can bear fruit at will, the reason why more and more people pay attention to pruning is because the tree shape has a great impact on the fruit. If the shape of the peach tree is a whole and there is no obvious layering, then the light inside the peach tree will be seriously lacking, and it will be difficult for flower buds to develop in such a situation, let alone bear fruit. Even if there are some results, in the end, they will be thought to be falling one after another due to lack of light.

The pruning of the peach tree should be taken seriously, this is a good opportunity to adjust the shape of the tree, otherwise it will be regretted if it does not bear fruit.

1. Insufficient nutrients. If the nutrients are insufficient for a long time, the fruit will fall off more and more. 2. Pests and diseases are a big stumbling block to high yields. Solution: Reasonable fertilization, fruit tree growth and fruiting need soil fertility to support; Watch out for pests and diseases.

It may be that it hasn't been pruned for a long time, or the nutrition can't keep up. It can be effective in fertilizing fruit trees and pruning off some old branches.

Reasonable pruning according to the individual aging degree of the peach tree is the means that must be taken to prolong the fruiting of the peach tree and restore the tree. There is a proverb in our countryside called "peaches are three miles and four walnuts are eight years". Peach trees are a period of rapid growth of one to three years.

In the fourth year, the fruit began to be grafted, and in the 7th and 8th years it entered the harvest period, and in 12 and 15 it began to decline, and various insects began to infect the branches. At this time, we should take measures to alleviate the impact of the aging of peach trees. Therefore, the fruiting rate of peach trees is particularly low.

Be sure to fertilize more and water frequently so that the yield will be increased.

The amount of fruit in the peach tree is not good, it may be caused by malnutrition, it is recommended that everyone must do a good job of pollination, after the fruit is set, the branches need to be pruned, and the fruit is removed.

1. Low fertilizer and water input. In the young tree stage, if the fertilizer and watering are less and the growth is allowed to grow, the young tree is not nutritious enough and it is difficult to meet the material needs of the flowering stage.

To this"Hungry type"Young trees should be increased with fertilizer and water to improve their nutritional status in order to bear fruit in time.

2. Improper fertilization. Too much nitrogen fertilizer, too little organic fertilizer, and too much water make it difficult for young trees to grow and flower.

3. Improper pruning. For young tree pruning, if it is shortened once a year, and it is too heavy and short, it will inevitably cause vigorous growth, unstable tree momentum, and it is difficult to flower and bear fruit.

The pruning of young trees should be based on the long-term goal of shaping, with the purpose of increasing branches and expanding the crown and stabilizing the tree potential.

4. The angle of the branch is not open. If it is a young tree with no opening at the angle of the branch, the tree will inevitably be vigorous and not slow, the growth center will move outward, the inner chamber will be closed, the ventilation and light transmission conditions will deteriorate, and it will be difficult to flower and bear fruit.

The improvement measure is to open the branch angle during the growing season by brace, pull, pin, hanging, etc., which is the structural basis for early fruiting.

Entering July is the peach season, the peach production during this period accounts for more than 60% of China's peach production, these peach varieties on the market are ripe, and the subsequent peach varieties are late-maturing varieties. Late-maturing peach varieties have developed rapidly in recent years, mainly because they are at the peak of staggered blooming and have good market conditions. The point is that they taste better than early-maturing varieties, so they are favored by growers.

Although late-maturing peach varieties have higher economic benefits, but due to the long growth cycle, the management technical requirements are relatively high, this is the most headache for farmers is the problem of fruit dropping, we are about to pick in the market but began to drop fruits, it is understood that some varieties of fruit drop problems reached about 20%, so that farmers are very helpless. The problem of fruit loss of late-maturing varieties is serious, which is not only related to the variety, but also related to the plant protection and farmer management of peach tree diseases.

How to solve the problem of late ripening of peaches? Teach you a little trick, many kinds of peaches are used, so in the face of the problem of late-ripening peach drops, what precautions do we have? What is the cause of the problem with dropped fruits?

How to prevent and control in advance? Today we will share this issue with growers, hoping to have some reference significance for growers.

There are several main reasons for fruit drop in late-maturing peach varieties: the pruning of the leaves in winter is too thick, which is a problem for many growers. Winter pruning retains that the fruit branches are too thick, the expansion of the peach and the distance between the fruit branches become larger, the stem becomes shorter, and the end result is that the fruit branch that is too thick says that the peach is stiff, and the experienced fruit will find that the farmer's fruit drop is better quality peach, and the lower part of the peach will have very obvious strangulation marks, which is due to the growth and fall of the peach, when the fruit branches are too thick and squeezed against each other.

Overload and insufficient nutritionMany growers blindly pursue high yields and are unwilling to flower and thin fruits, resulting in an imbalance in the ratio of leaves and fruits, and the nutrients produced by the leaves are not enough to supply fruit development. Farmers keep fruit branches that are too long, nutrients are transported over long distances, and poor peach development can also lead to fruit loss problems.

It may be due to the lack of trace elements in the soil or improper fertilization resulting in insufficient soil fertilizer to provide normal nutrients to the fruit trees, or it may be that the peaches are too large and squeeze each other to cause a large number of fruit drops.

It may be often windy and rainy, so this situation occurs, or it may be physiological fruit drop, which is certainly not accidental. Or in life there is not a good seedling process.

It may be that your fertilizer and water management is not particularly good, and there is no way for peach trees to better absorb some nutrients, so there will be fruit drop.

Generally seedlings can bear fruit in 3-5 years. If it is grafted, it will be fruitful in the second year.

The requirements of peach trees for the main nutrients: the needs of peach trees for the three elements are mainly nitrogen and potassium, and the demand for phosphorus is less.

(1) Nitrogen: peach tree new shoots grow a large amount, the fruit is large, more sensitive to nitrogen, too much nitrogen in the early fruiting trees of young trees is easy to cause new shoots to grow and delay fruiting, aggravate physiological fruit drop, and the amount of nitrogen fertilizer should be properly controlled. As the tree ages and yields, the nitrogen requirement also increases.

When nitrogen is insufficient, the growth of new shoots is small, the branches are thin and short, which affects the differentiation of flower buds, and the fruits are small, the color is poor, the quality is low, and the cold resistance of branches and buds decreases.

2) Phosphorus: Peach requires less phosphorus than nitrogen and potassium, and its main role is to make pollination and fertilization good, increase the candy content of the fruit and promote the formation of flower buds. When phosphorus is deficient, the fruit is dull, the flesh is soft, the taste is sour, and the fruit is sometimes spotted or cracked.

3) Potassium: peaches need more potassium, when potassium is sufficient, the fruit is large, the sugar content is high, when potassium is deficient, the fruit is small, deformed, early, and the leaves roll into gray-green.

Three peaches and four pears for five years, jujube trees make money that year!

Peach tree seedlings bloom and bear fruit in the third year, and a few bloom in the second year!

More than half of the peach tree grafted seedlings have flowered and borne fruit in the second year!

Five-year-old peach trees, whether they are seedlings or grafted seedlings, should already be in the full fruiting period!

When pruning, the young shoots, new branches, and new shoots should be wiped with buds, topping, thinning, twisting, and bending techniques, and the direction, position and angle of the branches should be adjusted to promote the young trees to branch more and grow into strong fruiting branches as soon as possible.

When the main branch is extended to about 60 cm, it is necessary to pluck the top, remove the tender shoots of about 10 cm, or twist the tips to promote the germination and growth of the secondary shoots, and form a good fruiting technique. For competing branches and erect branches, twist the tips at the base 5 to 6 inches to improve internal light.

When pruning, it is necessary to pay attention to the balance of the direction and growth potential of the backbone branches, and the small side branches on the extended branches, crossing, overlapping, and dense squeezing are thinned or retracted, and the other ones are cut about 10 cm, and the development of the branches is too dense to be properly thinned, and the strong and weak are left.

If the peach tree does not bear fruit, it is best to cut off all the branches and branches next to it, and after cutting it off, let him slowly grow leaves and sprouts, and finally deal with it well.

Just cut it down and replace it with a new one.

How to deal with peach trees that have been planted for 4 years and have no fruits?

Hello, your problem teacher will help you inquire as follows: Bu Sha starts from the following two aspects: 1. Pollination.

It blooms abundantly, but rarely bears fruit. For this variety of peach trees, pollinators generally need to be configured, and when building a peach orchard, 1-2 main varieties are selected, and then multiple pollinated varieties are configured. This increases both the yield and the variety of the fruit.

2. Sparse Jizhou fruit. It is usually performed in early May, about 20 days after the flowering. At this point, the size of the fruit can be distinguished.

Stunted, deformed, and straight front buried fruits, small fruits, and leafless fruits should be thinned, and large and well-proportioned long fruits should be retained. Trees that have been carefully thinned can not be thinned this time, otherwise 60-70% of the total number of fruits needs to be thinned. I hope the teacher's reply can help you!

Have a great day! Thank you!

1. Fruit fall period Peach fruit fall is generally divided into three situations and three periods. (1) The first stage of fruit drop is within 1 2 weeks after flowering, and the loss is the unenlarged ovary, mainly due to the lack of pollination and fertilization conditions, incomplete flower apparatus or pistil degradation. The emergence of this phenomenon is mainly due to the poor management of the summer of the previous year, which affected the differentiation of flower buds and the formation of flower organs, or the pollen is sterile and the germination rate is low, and the fertilization ability is lost.

2) The second stage of fruit drop is 3 to 4 weeks after flowering. At this time, the ovary has been enlarged, or due to incomplete fertilization, the development of the embryo is hindered, and the young fruit lacks the hormone of the embryo; or due to rainy weather during the flowering period, which affects pollination; Or the flowering period is hypoxic, and the young embryos lack protein** and stop developing. All these reasons can cause fruit drop.

3) The third stage is the young fruit that has been fertilized, in the process of development. Fruit falls due to the cessation of embryonic development in the middle of the process. This period is about the beginning of May and early June, when the embryo and the new shoot are in vigorous growth, the period when a large amount of nitrogen is needed, due to the lack of nitrogen, or too heavy, the new shoot grows too vigorously, and takes away the nutrients needed for fruit development, resulting in the lack of nutrition in the embryo, stops developing and falls the fruit.

2. Preventive measures The following measures can be taken according to the peach fruit fall period and reasons to improve the fruit setting rate of peach trees. (1) After fruit harvest in autumn, strengthening fertilizer and water management is an effective method for fruit drop caused by incomplete pistil development, in addition to treating pests and diseases, reducing leaf fall, improving tree nutritional conditions, promoting flower bud differentiation, and improving the quality of flower buds. For varieties that lack pollination, pollinators should be deployed, or orchard bees and artificial pollination should be used.

These are all effective measures to prevent early fruit dropping. (2) To prevent fruit drop in the later stage, we should focus on the appropriate fertilizer and water before the hard core, and adjust the amount of nitrogen fertilizer, not too much and not too little; In the rainy season, it is necessary to drain water in time to prevent water accumulation in orchards, carry out soil management in time, and improve root growth conditions; 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 increased. In addition, attention should be paid to the control of pests and diseases to prevent early defoliation.

In addition to strengthening the comprehensive management of peach orchards, spraying auxin 2,4 days and gibberellin after flowering can also improve the fruit setting rate and prevent the occurrence of peach fruit fall.
