Why do peach trees bear more fruit, and the leaves of peach trees fall off during the fruit bearing

You can try the following methods: 1. Fruit fall period There are generally three periods of peach fruit fall. The first stage of fruit drop is within 1 2 weeks after flowering, and the ovary is not expanded, mainly due to the lack of pollination and fertilization conditions, incomplete flower apparatus or degeneration of pistils.

The emergence of this phenomenon is mainly due to the poor management of the previous summer, which affected the differentiation of flower buds and the formation of flower organs, or the sterility of pollen and low germination rate, and the loss of fertilization ability. The second stage of fruit drop is 3-4 weeks after flowering. At this time, the ovary has been enlarged, or due to incomplete fertilization, the development of the embryo is stunted, and the young fruit lacks the hormone of the embryo; or due to rainy weather during the flowering period, which affects pollination; or lack of oxygen during flowering, the young embryo lacks protein** and stops developing.

All these reasons can cause fruit drop. The third stage is the young fruit that has been fertilized, in the process of development. Fruit drop occurs 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 shoots are in vigorous growth, and a large amount of nitrogen is needed. 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. In addition to treating pests and diseases, reducing defoliation, improving the nutritional conditions of trees, promoting flower bud differentiation and improving the quality of flower buds, strengthening fertilizer and water management after fruit harvest in autumn is an effective method for fruit drop caused by incomplete development of pistils.

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. 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, 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. In addition to strengthening the comprehensive management of peach orchards, auxin was sprayed for 2,4 days after flowering, and gibberellin was sprayed. Good luck!

There are more good years, and more vigorous periods.

Influential. If all the leaves are gone, there is no way to photosynthesize, there is no way to absorb nutrients, and peaches cannot ripen often.

1. What is the cause of a large number of peach trees losing their leaves?

In general, the problem of a large number of peach trees losing leaves may be due to improper fertilization, or it may be due to light. However, in terms of actual planting experience, it should be more intuitive that the large amount of leaf litter caused by bacterial perforation disease of peach trees should be more intuitive. The disease occurs in all peach-producing areas, especially in poorly drained orchards or rainy years, and if the control is not timely, it can cause a large number of fallen leaves and seriously affect the tree's potential.

2. The main symptoms of bacterial perforation disease in peach trees.

1. Leaf damage: There are water-stained spots on the back of the leaves, which gradually expand into purple-brown to black-brown lesions, surrounded by water-stained yellow-green halos, and then dry up and fall off to form perforations.

2. Branches are harmed: brown to purple-brown round depression lesions appear on the tips of branches. The 1 2-year-old shoots of severely planted plants die in winter until bud break.

3. Fruit damage: small black spots appear on the fruit surface, gradually showing dark purple ** sunken lesions, and the surrounding edge is water-stained. When the humidity is high, there is a yellowish-white sticky, and cracks occur when dry.

3. Preventive measures and prevention methods.

1. Precautionary measures.

1) Pay attention to ditching and drainage, increase organic fertilizer, avoid partial application of nitrogen fertilizer, and prune reasonably to ventilate and transmit light to the peach orchard, so as to enhance the tree potential and improve the disease resistance of the tree.

2) Clearing the garden in winter and spring to reduce the source of overwintering diseases. Before spraying the garden cleaning agent, be sure to cut off the diseased leaves, fruits and branches, and burn them or bury them deeply.

3) For peach orchards with high air humidity, plant ash can be sprinkled on the orchard ground, which can not only reduce the air humidity in the orchard, but also supplement the plants with potassium fertilizer, and can be polymerized with potassium dihydrogen phosphate by soil chefs.

2. Prevention and control methods.

1)**Scheme: When the disease is mild, spray with biological pesticides diluted with 400 times, and use the drug once every 10-15 days; When the condition is severe, dilute 300 times the solution and spray once every 7-10 days.

2) Spraying protection: spray 30 times of 5% crystal stone sulfur mixture and 400-500 times of 30% glue suspension before germination. After germination, spray 3000 times of 72% agricultural chain demand soluble powder or spray 600-800 times of 20% molkarazole wettable powder, and 200 times of 4% chunleimycin wettable powder.

Spray 1 time in half a month, a total of 2-3 times.

If photosynthesis is insufficient, it must have an impact, why are the leaves lost?

Of course there is an effect, the leaves are photosynthesized.

Excessive fruit in peach trees may be due to one or a combination of the following factors:1Improper pruning:

If the peach tree is not pruned properly, such as over-pruning or under-pruning, it can cause the tree to produce too much nutrients, which can lead to too much fruit. 2.Over-fertilization:

Peach trees can also cause the tree to be overnutriently nutrient or use too much nitrogenous fertilizer, resulting in excessive fruit growth. 3.Lack of fruit tumor regulation:

Fruit tumors are an important growth hormone production site that regulates fruit growth through the release of Nesshorn hormone from fruit tumors. If the fruit nodules do not function properly, the peach tree may produce too much fruit. 4.

Environmental factors: Rainy and humid climates and warm temperatures in summer can also promote overgrowth of peach trees and produce excessive fruit. 5.

Variety differences: Some peach tree varieties are born with more fruit than others. Therefore, if you want to control the excessive fruit yield of peach trees, you need to prune properly, adjust the amount of fertilizer, improve soil quality, and properly control fruit tumors.

Summary. Hello dear, happy to answer your <>

The peach tree bulging stage refers to the stage when the peach tree fruit begins to develop, and this stage usually occurs within a few weeks of flowering. At this stage, the peach tree fruit will gradually expand and begin to form a pulp and pit. The bulking period usually requires suitable climatic conditions and adequate nutrients**.

Whereas, peach tree fruit drop refers to the phenomenon that peach tree fruit falls before it matures. There are many reasons why peach trees drop fruit, including fruit injury, pest and disease infection, branch breakage, etc. In addition, environmental factors such as drought, high temperatures, and low temperatures may also cause peach trees to drop fruit.

In order to prevent peach trees from falling fruit, some measures can be taken, such as timely pruning of branches damaged by pests and diseases, reasonable fertilization and watering, and maintaining a suitable ambient temperature. In addition, reasonable flower and fruit thinning can also help reduce the load on trees and improve fruit quality and yield.

What is the fruit drop of peach trees during the fruit expansion period.

Is fruit drop during the fruit expansion period of peach trees the reason for the flushing of calcium ammonium nitrate?

<> kissing, the following is a supplement; The fruit expansion stage of peach trees refers to the stage when the fruit begins to swell, and if a large number of fruits fall off naturally during the noisy vertical fruit swelling period, it may be related to the application of ammonium nitrate calcium. Flushing of calcium ammonium nitrate is a commonly used plant growth regulator that can promote plant growth and fruit expansion, but may cause fruit to fall off if used in too large a dosage or at an improper time. Therefore, in agricultural production, when using calcium ammonium nitrate, the correct use method and suitable application time should be followed to avoid adverse effects on the fruit.

Peach fruit drop control measures: high concentration of ethephon, organophosphorus pesticides in the water ammonia thion, methamidophos, trichlorfon, dichlorvos, monocrotophos before and after the flowering period often cause apples, peaches and some vegetables to fall flowers and fruits.

After flowering, phosphorus and potassium fertilizers should be added to top dressing to reduce early fruit drop. Apply 150 grams of urea, 200-250 grams of superphosphate, 250 grams of potassium chloride or 10-15 kg of plant ash per fruiting tree.

With the expansion of fruit and the development of seed embryos, it is necessary to enhance the absorption of nutrients, and in the nuclear hardening stage, the manure of decaying and livestock is used to apply available phosphorus and potassium.

fertilizer, or compound fertilizer is more effective. For peach trees with large crowns, the amount of fertilizer should be increased as appropriate.

Why don't peach trees bear fruit?

Hello, I am helping you to inquire about the relevant content, and I will reply to you immediately.

In the case of peach trees not bearing fruit, first confirm that the peach blossom is not used for flower viewing, and peach trees generally do not bear fruit. There are many reasons why fruit trees do not bear fruit, which are mainly determined by the following four reasons: first, it is now in the flowering period and has not yet begun to bear fruit; second, pollination is unsuccessful; the third is that there is too much water, and the small fruit falls off after hanging it; Fourth, there are pests and diseases.

Summary. Hello, the impact has.

1.Poor tree shape. 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.

2.Lack of fertilizer and water. Lack of fertilizer and water is a common cause.

3.The tree is thriving. In fact, the tree is not ideal for peach trees, which will vegetative growth is stronger than reproductive growth, and the popular point is that the nutrients have grown taller, and the fruit has no nutrient supply, so the natural fruit cannot grow fruit.

4.Pollination is not ideal.
