The apple tree is okay, but the fruit is small, what is the reason?

It may be due to malnutrition, or it may be due to the variety, and it is necessary to water and fertilize in time.

It must have been that the apple branch was not repaired. Fertilizer is not in place, which leads to smaller fruits. There is also no irrigation in place.

There are many farmers who grow apples in rural areas, and these fresh fruits have long become common fresh fruits, so the market is more common, but the quality of apples produced by growers is also different.

Especially the appearance and the edibility of the pulp, some are big and sweet, some are dull in color, there is little fruit juice, and some are large but very light, so what is the reason for the large and light apples? Let's get to grips with it! What is the fruit of the apple orchard that is very large but very light?

1. Insufficient fertilizer and water.

Nowadays, planting apples itself is a more difficult matter, especially in the case of fertilizer and watering, it must consume a lot of human resources, and the lack of fertilizer and water is the primary reason for the large and light apples, which is also the neglect of the management methods of growers.

As a result, for example, in arid climates, the production of apples can easily lead to apple trees.

If the rise is weak and the strong bar cannot come out, this will cause the apples produced by the sidelines to be large and light.

2. It's not circumcision.

In the process of apple planting, pruning is an indispensable link, which is of great help to fill in the nutrients and improve the quality of apples.

3. Improper use of chemical fertilizers at the young fruit stage.

Nutrients and fertilizers in the young fruit stage of apples are important to ensure the quality of apples, and emulsifiable fertilizers can not be applied in the young fruit stage, which can easily lead to large and light apples, reduced value of goods, not sweet taste, and lack of moisture.

4. Spraying too many pesticides.

In the process of apple planting, too much chemical fertilizer spraying, it is easy to cause harm to the quality of the fruit, the content of the spraying is too large, causing fertilizer damage to the fruit, resulting in the air hole tethering, the occurrence of a large and light situation, is not conducive to improving the quality of the apple.

5. No bagging.

Bagging is important to ensure the accumulation of apple sugar, but also to enhance the attributes of apples commodity attributes, many farmers in order to better convenience, it is not easy to bag the last peach tree, the production of apples after drying, although large, but the net weight is very light.

If the apple tree is dry without water, it will lead to the situation of accompanying and taking the hair, and there is not enough nutrients, which may also lead to this situation, which will cause the apple to look big, but very light.

This condition is generally caused by the injection of bulking hormone, so the apple grows too fast.

It is caused by insufficient fertilizer application, and we must pay attention to fertilization and watering during the planting process.

This is because of the disease, there are already a lot of small insects in it, so all the flesh is eaten by the ruler Zen, and it is also because there is a lack of water and fertilizer in the Qi skin when planting.

Climatic factors such as too much fruit, insufficient fertilization, too much nitrogen fertilizer, insufficient ventilation and light, etc., scientific fertilization, timely insect control.

The apple tree can be grafted and the variety can be given, so that the proposed apple will be large and sweet, and the variety will be enhanced.

If the apple orchard does not pay attention to pruning, the orchard environment is closed, the humidity is high, bacteria, fungi, insect pests and other large occurrences, and the red spider and lobular disease will eventually harm the leaves, and the serious infection will lead to abnormal shedding of early leaves, affecting the normal supply of nutrients to the tree. These will have an impact on the size of the apple.

The sparse flowers are carried out according to the principle of "an inflorescence with a spacing of 20cm between the top and bottom, left and right, and front and back", but attention should be paid to retaining early and strong flowers. Fruit thinning begins 7-10 days after the apple flowering, according to the principle of "one inflorescence and one fruit". Do a good job in the orchard drought and waterlogging measures, arrange a good watering and drainage system, and ensure that "drought has water, waterlogging can drain".

It is also necessary to pay attention to the prevention and control of orchard pests and diseases, especially the red spider insect pests that eat away at the leaves, which can be controlled by spraying avermectin solution before flowering, after flowering, and in early June.

Fruit trees need to consume a lot of nutrients and water during a series of life activities such as germination, growth, flowering, fruiting, flower bud differentiation, and nutrient storage.

In the "big year", due to the excessive number of flowers and fruits, a large amount of nutrients in the tree body is consumed, so that the fruit tree does not have enough nutrients to promote the formation of flower buds, and the phenomenon of "small year" occurs in the second year.

In the "small year", due to the small amount of flowering and fruiting, the nutrients of the tree body are mainly used for growth. The organic nutrient accumulation of fruit trees is more, which promotes the formation of a large number of flower buds, and the phenomenon of "big year" is presented in the second year.

Summary. 1. Symptoms Zinc deficiency can cause apple tree lobular disease. Symptoms appear in spring, the diseased branches germinate late, the leaves are narrow and slender, hard and brittle, the leaf margins are slightly rolled upward, and the leaf color is pale yellow-green or uneven.

The internodes of the diseased branches are significantly shortened, and the leaflets are clustered on them. Sometimes a new branch develops in the lower part of the diseased branch, but it still shows the same symptoms. The flower bud differentiation of the diseased plant is reduced, and the flowers are small and pale in color, which is not easy to set fruits. The results are real.

1. Symptoms Zinc deficiency can lead to the eradication of apple tree lobular disease. In spring, the diseased branches germinate later than the royal branches, the leaves are narrow and slender, hard and brittle, the leaf margins are slightly rolled upward, and the leaf color is pale yellow-green or uneven. The internodes of the diseased branches are significantly shortened, and the leaflets are clustered on them.

Sometimes a new branch develops in the lower part of the diseased branch, but it still shows the same symptoms. The flower bud differentiation of the diseased plant is reduced, and the flowers are small and pale in color, which is not easy to set fruits. The fruit of the macro eggplant.

Caused by zinc deficiency.

1. The problem of malnutrition in the first season of Fast Retailing is generally not easy to find, because the problem can only be detected after the apple bears fruit. It may also be because the audit of the apple tree at the upper level is not too strict, so it is allowed to flow to the generation of Zichangyou for planting. The direct consequence of malnutrition is that the fruit does not grow much, as if it has not been developed, but in fact it has already grown, so it will eventually be a failed fruit and will be eliminated.

2. Insufficient fertilization If there is no problem with the variety and quality of seeds, it may also be caused by insufficient fertilization. There are several stages of fertilization, one is the fertilization when planting apples, and the other is the top dressing when flowering and fruiting, each top dressing is very important, it needs to be fertilized in sufficient amount, and irrigated with clean water, so that the effect of fertilizer is easier to be absorbed by apple trees. If the fertilization is done haphazardly, it may cause the fruit to not grow much.

Fertilization can be applied with Aonong Le biological fertilizer, which is made of Chinese herbal medicine, seaweed and minerals, and then added 8 kinds of beneficial microbial bacteria to ferment the Chinese herbal microbial fertilizer. It can improve the chlorophyll content of leaves to achieve the effect of improving quality and efficiency, nutrition and rejuvenation, and a variety of beneficial microorganisms can effectively improve the soil, improve the air permeability of the soil, and improve the utilization rate of soil organic matter. 3. Unsuccessful pollination is a difficult thing to define, because after the pollination of the apple, we cannot verify it one by one, but can only judge its pollination according to the weather conditions.

If there is frequent rain during pollination, the success rate of pollination may be reduced, and manual pollination is needed to help ensure that the apple pollination is more successful in order to grow normal-sized apples in the later stage. 4. When the apple tree begins to grow fruit after flowering, some farmers will think that the more fruit, the better. But in fact, the apple tree has a certain carrying capacity, and too much fruit can put a lot of pressure on the apple tree.

On the one hand, there is the problem of nutrient distribution, and on the other hand, it may cause the apple tree to bear too much weight, resulting in insufficient nutrient absorption, so the fruit does not grow much. 5. Branches and fruits compete for nutrition (a problem that fruit farmers tend to ignore)Branches and fruits compete for nutrition, which is roughly manifested in three periods, the first period is after flowering to before fruit setting. During this period, if the tree is stable and there are few sprouts, the fruit setting rate is significantly higher (except for natural disasters).

If the amount of strips produced during this period is large, the fruit set is generally small; The second period is the fruit expansion period, which is about 6-8 months. If the branch growth is large during this period, the fruit is relatively small, and if the branch is strong, the fruit is significantly larger; The third period is about a month before the fruit of late-maturing varieties. Around the end of September, if the branches are still growing in large quantities, not only will the fruits not grow much, but also the coloring and taste will be poor.

The apple tree has many and small fruits this year, how to manage it in the later stage.

Hello dear! <>

We are happy to answer the question of how many and small apple trees are hungry, usually due to too many fruits or poor growing conditions. Here are some post-management suggestions:1

Fruit thinning: Too many fruits can cause nutrients to be distributed unevenly in each fruit, resulting in smaller and less sweet fruits. Therefore, it is necessary to thin the fruit in time to retain the high-quality fruit on the tree.

In general, the distance between each fruit should be around 5-10 cm. 2.Trim:

During fruit development, the leaves and branches of the apple tree consume a lot of nutrients and water, so pruning needs to be done in time to ensure the growth and development of the tree. The principle of pruning is to preserve high-quality shoots and healthy leaves, and remove wilted and weak branches and leaves. 3.

Watering and fertilization: During fruit development, apple trees need a lot of water and nutrients to support the growth and development of the fruit. Therefore, it is necessary to water in time, and apply an appropriate amount of organic fertilizer or compound fertilizer to promote the development of the fruit and increase the sweetness of the fruit.

4.Pest control: During fruit development, apple trees are susceptible to a variety of insect pests, such as aphids, mites, leaf-eating insects, etc.

Therefore, regular pest control treatments are required to ensure the health and quality of the fruits. To sum up, for the case of many and small fruit in apple trees, it is necessary to manage from the aspects of fruit thinning, pruning, watering and fertilization, and pest control to ensure the quality and yield of the fruit.
