How to manage fruit trees in the summer of high temperature and humidity?

Summer is the season of high temperature and humidity, with high temperature and high humidity, and the climatic conditions are very conducive to the occurrence and spread of pests and diseases. At this time, how to do a good job in the management of fruit trees is a critical period to prevent and control the harm caused by pests and diseases. From the perspective of the "confinement period", it is true that the summer management of fruit trees should be the most important part of the year, and the level of management not only affects the yield and fruit quality of the year, but also affects the number of flower buds and yield of the fruit trees in the next year.

Manage flowers and fruits, fertilization, and drainageFor fruit trees in the fruit growth period, it is necessary to pay attention to the problem of fruit bagging, and for fruit trees in the flowering or young fruit stage, it is necessary to pay attention to the problem of thinning flowers and fruits to ensure reasonable load. In summer, most fruit trees are facing a special period of fruit picking or will be picking, generally after fruit picking, it is necessary to pay attention to the application of "confinement fertilizer" to ensure the flower bud differentiation of fruit trees.

Do a good job in the prevention and control of diseases and insects, do a good job in thinning dense branches to improve the quality of fruits: In this season, it is in the season of high temperature and high humidity, and the problem of pests and diseases is high, so special attention needs to be paid to it. For the prevention and control of diseases, on the one hand, it is necessary to scrape off the lesions in time, and on the other hand, it is necessary to remove the source of bacteria in the field in time; The task of summer scissors is to thin, control the length and promote flowers.

For unfruited fruit trees, the branches were softened, opened at an angle, and slowed down. <>

As many of us growers, we don't pay attention to the management of this period. Why? Because most fruit growers only pay attention to pre-fruit management, and ignore the management during and after fruit.

Although many of our fruit farmers know the importance of fruit tree management during this period, many fruit farmers do not know what to manage well during this period and what aspects of management are truly in place. From a comprehensive perspective, summer is for fruit trees, and only by doing a good job in summer management can we ensure that fruit trees will continue to produce abundantly and steadily in the coming year, and there will be no problems such as "big and small years". In fact, there is no special management problem in the summer management of fruit trees, which is nothing more than to do a good job in the above aspects.

Fruit trees in summer with high temperature and humidity must prevent some plant fungal infections. It is very important to prevent some diseases, because such climatic conditions are very suitable for the breeding of some bacteria. In addition, it is necessary to remove some excess side branches and leaves, which is mainly to increase the ventilation of the fruit tree.

It is necessary to protect the fruit trees, do a good job of drainage, and some lowlands that are prone to water accumulation should be cleaned up in time.

Pay attention to the right amount of fertilization.

To inhibit the production of pests and diseases, when the humidity is high and the temperature is high, pests are very easy to occur, so we should pay attention to the management of pests and diseases.

At this time, the trees should be irrigated at an adequate frequency and with sufficient fertilizer. Because high temperatures take away a lot of water and make the metabolism of the fruit very lush, the demand for water and raw materials is very high.

Water the fruit trees frequently, fertilize the fruit trees, and spray some loosening agents on the fruit trees if there are pests and diseases. And also to spray some nutrient solution on the fruit trees, you can also spray some pesticides on the fruit trees.

At this time, it is necessary to drip water, so that the trees have a very good ventilation directly, and remove some weeds, so that the fruit trees can grow better.

Be sure to pay attention to watering, pay attention to water and fertilizer management, some special fruits need to be bagged in advance, so as to ensure the integrity of the fruit.

Summer is the vigorous growth season of fruit trees, the shoots and leaves are easy to grow, forming a deformed and strange shape, not using management, not conducive to ventilation, not conducive to receiving sunlight, not conducive to hanging fruit and fruit protection, not conducive to improving yield, and plays a great role in the growth and development of fruit trees. The canopy density is too large, which affects ventilation and light transmission, thinning overly dense branches, pruning some weakened branches, and branches damaged by pests and diseases, etc., which can not only be used to improve the summer growth of trees, but also slow down the occurrence of excessive pruning in winter, and make the growth of fruit trees more stable.

Twisting the shoots: When the new shoots are lignified, the hand holds the part of the 5 cm and gently twists it 180 degrees to change the direction, and mixes it with the petiole or pins it to other branches. Twisted shoots can hinder nutrient transport, change apical dominance to slow growth, and promote the formation of short and medium branches and flower buds.

Bunch of flower branches is due to the formation of perennial throwing, for the pruning of this kind of branches to pay attention to their respective sensitivity, the growth of the general bunch of flower branches can be shrunk by half, the growth of weak hair can be appropriately left a little longer, the growth of strong branches is left the longest, can be cut off about 1 3.

If there are yellow leaves, you should cut them quickly, which is a precursor to bad covering, and if you don't handle it well, the yield of the next year will be worrying. At the same time, it should be noted that the summer shears should not be cut too much, first, to maintain sufficient nutrients of the leaves, and second, to ensure that the pruned branches can not grow new heads.

Generally, it is about 15 cm left, and topping can enrich the branches of the fruit tree and make the branches fully lignified; It is conducive to the early maturity and increase of leaves, and strengthens the photosynthesis of fruit trees; Adjusting the branch group to promote flowering and fruiting is conducive to the fruit tree to resist the severe cold and make it safe to overwinter.

When the length of the annual branch reaches about 50 cm, the base is pinched outward every five to six leaves and twisted in the opposite direction, the purpose is to block the delivery of nutrients to the roots to facilitate the accumulation of nutrients to form flower buds, and at the same time, it can also change the angle of the branches to be too upturned to achieve the purpose of balancing the tree.

For the problem of soil, and also should be watered frequently, and also should maintain the yield, and should pay attention to the problem of pests and diseases, etc., these are management techniques.

This summer, because the temperature is very high, so when planting fruit trees, you must pay attention to watering them more, but when watering, it is best to choose around 7 p.m., regularly fertilize, prune branches, spray insecticides, and get rid of small insects.

The trick I know is to manage the fruit of the fruit trees, because the fruit of these trees is very fragile and if you don't observe their condition in time, then diseases can occur.

1. The orchard is flooded with water in summer, which is easy to cause the tree to grow vigorously and affect the differentiation of flower buds; If there is drought in the early stage and flood irrigation in the later stage, the water content is unbalanced, which is easy to cause fruit cracking; In the summer high temperature, after the orchard is flooded, it will cause a large number of capillary absorption roots to suffocate and die, although the soil water content is large, the capillary root death can not work normally, and the water transfer is blocked, resulting in leaf transpiration and water shortage, resulting in leaf burning or leaf wilting; Then there is water in the garden, and the water evaporates upwards at noon, and the lower fruit will be scalded to varying degrees. Therefore, watering should be irrigated with small ditches, or combined with flushing fertilizer water to replenish water and fertilizer in time to achieve the expected yield. 2. In the summer tube, nitrogen fertilizer is still more important, resulting in fruit trees can not stop growing in time, flower bud differentiation is less, and the fruit size is serious.

It will also cause the fruit to ripen late, the color difference and taste are light, and the fruit quality will decline. The correct approach is to increase the application of phosphorus and potassium fertilizer or low nitrogen, medium phosphorus and high potassium fertilizer and trace element fertilizer in summer, and the fruit is good for coloring and selling.

To carry out underground management, choose to evacuate moist soil, flower and fruit management, summer pruning, pest control, etc., these are all summer fruit trees that need to be managed, and the growth of fruit trees should be observed at any time.

In the summer, if the fruit trees appear yellow, it is important to lose them as soon as possible, because this is a bad omen. In the summer, it is also important to give the fruit tree enough nutrients so that it can grow better.

1.Cultivating loose soil. 2.Ditching and fertilizing. 3.Tree tray cover grass. 4.Pay attention to proper irrigation. 5.Pay attention to the prediction of pests and diseases.

I know that when managing fruit trees in summer, you need to control the temperature difference to be larger, so that the fruit will be sweeter, and at the same time, you need to replenish water so that the fruit will be full of juice.

First of all, it is necessary to observe the planting environment of these fruit trees in time, and to ensure the temperature, as well as the humidity, and to kill insects in time, and to fertilize in time.

At this time, it is necessary to water and weed in time, but also to fertilize, to improve the fertility of the soil, to do scientific pruning, to fully absorb sunlight and ventilation, and generally to remove those weak fruits, leaving some large fruits.

The fixed fruit generally leaves a single fruit in each order, and the fruit spacing is 20 25 cm, leaving good fruits and large fruits, and removing residual fruits in time. For small trees, wang trees, and wang branches, double fruits can be left.

1. Watering: In winter, it is necessary to apply sufficient water to the fruit trees, and water them once a day in the morning and evening, which can improve the air permeability of the fruit trees and keep the soil dry. At the same time, it is necessary to prune the branches and leaves regularly to promote the growth of new shoots.

2. Fertilizer and water management: appropriately increase the proportion of fertilizer and water, add diluted urea parsley or urea at a ratio of 10 per day, and then irrigate with 50% potassium nitrogen oxide solution to prevent water accumulation.

3. Watering: Spray water every half month to make the soil moist and avoid excessive drying.

4. Light: Fruit trees usually need strong sunlight in summer, so they should be shaded and placed in a well-ventilated place indoors.

5. Reasonable watering: Fruit trees need plenty of light in spring, otherwise they will wither. At this time, it should be watered in time so that the nutrients can be absorbed quickly.

6. Pest control: Preventive measures must be taken before the onset of fruit trees, in addition to reducing the damage of pests and diseases, attention should also be paid to controlling the occurrence of pests and diseases, so as to prevent fruit trees from dying again.

7. Nutrients**: The nutrients required by fruit trees are mainly vitamin C, carotene, calcium, phosphorus, iron, etc., and the content is abundant, which helps to improve physical fitness after eating.

8. Economic support: Fruit tree cultivation is basically simple plant ash or coal, which can also be used as fertilizer.

Fruit trees have low maintenance costs, large input yields, easy survival, and sweet and attractive fruits, which are very suitable for planting in summer.

9. Fertilization: Fruit trees need to be fertilized frequently, especially after flowering, and fertilized every three or four days to ensure that fruit trees grow vigorously.

10. Fertilization: Fruit trees grow faster and need to be fertilized, even if you stop fertilizing, you can continue to fertilize to ensure the stable growth of fruit trees.

11. Disinfection: Fruit trees need to be disinfected during the growth process, and only clean can they kill pests and diseases, whether it is a fruit tree or a fruit tree, we should try to remove pests and diseases to avoid damage to fruit trees.

How to hydrate fruit trees in high temperature weather is a question that many people have nowadays, after all, the high temperature weather in summer is continuous, and many areas have the problem of leaf rolling because of drought.

There is no accurate answer to how to hydrate fruit trees in hot weather, after all, there are thousands of types of fruit trees on the market, so I will take apple trees as an example, apple trees should be watered carefully, not watered at high temperatures, you can water after 4 o'clock in the afternoon to evening, the effect is the best, and it can also prevent the problem of root damage.

In addition, drip irrigation can be used when watering apples, which can not only save water, but also save time, effort and labor. Now after the apple is bagged, the fruit will grow slowly, and you can apply a balanced large number of elements water-soluble fertilizer, 10 kg per acre, increase nutrients**, and promote fruit expansion. Foliar sprays can be foliar with medium and trace elements such as iron and magnesium to prevent the fruit of the causal tree from absorbing a large amount of nutrients, resulting in a lack of nutrients and reducing photosynthesis in the leaves.

Whether the fruit trees should be watered every day in summer needs to be determined according to the weather conditions.

In summer, if there is little rain, you must water it, because if you do not water the fruit tree, it will cause drought, and the leaves of the fruit tree will roll up, making it easy to grow insects. If you don't get rid of insects in time, you won't be able to produce fruit and affect the yield of fruit. If there is enough rain in the summer, there is no need to water.

It depends.

For more than half a month of continuous drought, the leaves of fruit trees are curled and wilted, and watering should be carried out if conditions permit. Watering is not just a matter of watering, there are a few aspects to pay attention to. First, watering should be watered as much as possible in the morning and evening.

Avoid the high temperature in the middle of the day, and it is better to water it at night. The second is to cover the grass under the canopy after watering the water to reduce water evaporation. Third, the first watering after drought is easy to irrigate slowly to prevent fruit cracking.

Fourth, the orchard grows grass, which plays a role in protecting moisture.

High temperature weather has a certain impact on the flowering and fruit development of fruit trees, so it is necessary to take precautions to protect the healthy growth of jujube fruit trees. Here are a few suggestions:1

Water the fruit trees with the right amount of water. The water consumption of fruit trees increases in hot weather, so it is important to ensure that fruit trees have sufficient moisture** to avoid soil drought. 2.

Provide proper shade to fruit trees. You can build a shade net or build a simple awning around the fruit trees to effectively avoid the sun in hot weather. 3.

Apply appropriate fertilizers. In hot weather, the nutrient consumption of fruit trees will increase, so it is necessary to properly fertilize fruit trees to ensure their healthy growth. 4.

Do a good job in pest control. High temperature weather is easy to breed all kinds of pests and diseases, so it is necessary to find and take prevention and control measures in time. 5.

Prevent overflowering of fruit trees. Overflowering can burden the tree and make it more susceptible to high temperatures, so it is important to prune and control flowering at the right time.
