Why do the persimmons on the tree fall in love? Why does the persimmon tree fall as soon as it bloom

There are two reasons for fruit dropping. One reason is the physiological cause of the tree itself, and the second is the persimmon scale, a kind of insect. In total, your fruit drop is caused by these two reasons.

Persimmon scales account for a relatively small proportion of your fruit drop. Persimmon velvet scale, is a relatively small scale insect? , in the spring.

It goes up to the top of the tree, where it happens four to six generations a year, and it harms the shoots, and when the shoots come down, they move to the small fruits. After another stage, it is between the calyx and the fruit, where it is harmful, and after the damage is too much, the fruit falls.

The presence of persimmon scales is also a reason, and the root cause of fruit drop is the lack of development of these persimmon trees themselves.

Resources.

When it's ripe, it will naturally fall off.

The fruit is ripe and falling, what fruit always hangs on the tree?

The main reasons for fruit drop are:

1.Rainfall causes: persimmon growth period, a large number of fruit drop phenomenon, will also be related to the climate, weather influence, such as too much rainfall for too long, the growth period of persimmons, failed to receive photosynthesis, the fruit naturally fell off.

2.Climatic reasons: severe low temperature in winter and cold storage in the following spring, resulting in slight frost damage to the root neck (heavy in the southeast), affecting the nutrient reflux cycle Leaf and fruit drop occurred in the month.

3.Physiological causes of fruit drop: first, incomplete differentiation of flower buds, resulting in early fruit drop; The second is poor pollination, and some varieties do not have pollinator trees.

In particular, most of the sweet persimmon varieties in Japan do not have pollinator trees. then the fruit can not develop, and the early fruit drop is serious; The third is that the structure of the tree is unreasonable, the tree is tall, the branches are too dense, and the ventilation and light transmission are poor, which affects the organic nutrient accumulation of the branches.

4.Malnutrition: Malnutrition caused by lack of water and fertilizer will also lead to nutrient imbalance of tree type, which will also lead to unfavorable growth of new shoots, unfavorable germination, and easy to cause fruit drop in the fruiting period.

5.Causes of diseases and insects: Because persimmon trees are harmed by persimmon insects, scale insects, anthracnose, etc., most of them will cause persimmon fruits to become soft and then fall.

The solution to the fruit drop of the persimmon tree:

1.Intensified pruning, opening up the light path, increasing light and ventilation can reduce the degree of fruit drop in the inner chamber. For long branches, useless should be removed in time, and useful should be plucked in time after retention.

At the same time, it is also necessary to prune the fruiting mother branch reasonably, and the fruiting branch should be weak and strong, and the large fruit such as the mill persimmon should not exceed 3 fruits per fruiting mother branch.

2.At the early flowering stage, ring stripping measures are taken. The width is generally about centimeters, not too wide, and pay attention to leave the safety belt, that is, when the ring is peeled, do not peel into a whole circle, you can stagger the peel or retain a small part of the skin without peeling.

3.For sweet persimmon varieties, pollination trees or artificial pollination are required.

4.Strengthen soil management of water and fertilizer and enhance tree potential. Do not fertilize too much water before and after the flowering period, and spray 800-1500 times the liquid of Pica potassium dihydrogen phosphate on the foliar surface to prevent the growth of branches from competing with the fruit for nutrients and aggravating the occurrence of fruit drop.

5.Strengthen the control of pests and diseases, that is, the prevention and control of anthracnose and persimmon insects, to avoid causing fruit drop in the later stage, to ensure that the tree is not affected, and to reduce the occurrence of fruit drop in the current year and the second year.

6.Continuous spraying of 500 ppm of gibberellin or 1% urea at the early fruit stage can reduce fruit drop to a certain extent.

Persimmon trees have many flowers, and it is normal for flowers and fruits to fall. Under normal circumstances, if you keep a persimmon for each new shoot, you will basically not fall fruit again.

The reasons for the flower and fruit drop of the persimmon tree: 1. The physiological flower and fruit drop caused by the physiological disorder of the persimmon tree itself; 2. Flower and fruit drop caused by anthracnose or persimmon pedicles and other pests and diseases. The physiological flower and fruit drop caused by the physiological disorder of the persimmon tree itself generally has the following three times.

The first time: It occurs during the rapid growth period of new shoots, which is called falling buds. Bud drop occurs before the flowering of persimmon trees, mainly when the buds at the base of the fruit branches fall off.

The main reason is that the flower buds are not completely differentiated and the quality of single flowers is poor.

The reasons for the fall of flowers may be: 1. Caused by malnutrition. 2. Normal physiological fruit drop.

3. There are pests and diseases. Before flowering, at the young fruit stage and at the fruit expansion stage, the persimmon tree was sprayed once to make the fruit pedicle thicker, improve the nutrient delivery, preserve the flower, strengthen the fruit, and reduce the fruit drop rate.

The reason why the persimmon tree falls after fruiting may be caused by natural fruit drop, improper water and fertilizer, improper temperature or pest and disease infestation, etc., the branches will naturally break and drop the fruit after the fruit is ripe, improper watering and fertilization, and too low temperature will lead to fruit drop, and infection with pests and diseases will also lead to fruit drop of the persimmon tree.

1. Natural fruit fall

The persimmon tree has the phenomenon of all the fruits falling, not necessarily because of the maintenance or other problems, it is likely to be just a relatively normal physiological phenomenon, sometimes the persimmon tree hangs too many fruits, and the branches can not bear such a weight after the fruits are all ripe, and the fruit will naturally break and fall fruit.

2. Improper water and fertilizer

When watering and fertilizing, we should pay attention to uphold the principle of moderate amount, watering to do that the soil is not dry and not watering, watering enough watering, but to see dry and wet, can not have the phenomenon of water accumulation, fertilization should uphold the principle of thin fertilizer diligently, a small amount of many times to apply thin fertilizer, so as not to cause fertilizer damage and fruit drop.

3. Improper temperature

The persimmon tree has a strong ability to tolerate cold, and its fruit can continue to maintain a healthy state in lower temperatures, but it should be noted that the fruit of this plant will drop fruit in a large area under the condition of rapid temperature changes, so it is necessary to stabilize the temperature and not let it be in a rapidly cooling environment.

4. Pest and disease infestation

Because of the sweet smell and juicy characteristics of its fruit, it is easy to attract a large number of pests to gather, these pests suck juice and eat the plant, which will cause a large area of persimmon tree fruit drop, and at the same time, anthracnose and other diseases will also be at this time, if there is no timely treatment, the persimmon tree will also drop fruit.

1. There are actually two main reasons why persimmon trees drop fruits, one is the physiological fruit drop caused by the physiological disorder of the persimmon tree itself, and the other is because of the fruit drop caused by anthracnose or persimmon insects and other pests and diseases.

2. The degree of physiological fruit drop of persimmon trees varies greatly between varieties, such as the main cultivar of Taihang Mountain in Taihang Mountain, our province, the fruit drop of Da Mopan persimmon is lighter, generally not more than 10, and it is not easy to detect, while the Dahongpao variety is serious after entering the full fruit period, and the fruit drop rate is 2 3 at most.

3. Persimmon insects are generally cautious about fruit decay before and after wheat harvest, the first generation of damaged fruits is not easy to fall off, and will always hang on the tree, and the larvae pupate in it and continue to pupate the second generation. The color of the second-generation damaged persimmon fruit changes from yellow-green to orange-red, and it is easy to fall off when it changes from hard to soft. The second is anthrax.

It occurs in the late growth period, usually in September, causing fruit drop.

Summary. Hello dear, when the leaves of the persimmon tree fall, the persimmon tree may be affected in some way. Here are some of the things that can happen:

Reduced photosynthesis: The leaves of the persimmon tree are the main organs that carry out photosynthesis, and through photosynthesis, the leaves are able to absorb sunlight and convert it into energy, providing the nutrients needed for the tree to grow. If the leaves fall, the efficiency of photosynthesis will be reduced, causing the persimmon tree to grow slower.

Reduced nutrient absorption: Leaves are one of the organs that carry out water and nutrient uptake in plants. The stomata on the leaves absorb carbon dioxide, while the roots absorb water and nutrients from the soil.

If the leaves fall, the tree's ability to absorb nutrients will be limited, which may lead to stunted plant growth.

In addition: Decreased persimmon production: Persimmon is usually the fruit of the persimmon tree, and when the leaves fall, the persimmon tree may be affected, resulting in a decrease in the yield of persimmons.

Because the fruit needs adequate light and nutrients** to grow and develop properly, a persimmon tree that lacks leaves may not be able to provide enough nutrients and energy for the fruit. Decreased cold tolerance: The leaves of the persimmon tree can protect the trunk and root system from cold weather damage.

If the leaves fall, the trunk and root system of the persimmon tree will be exposed to the cold, which may cause the tree to lose its cold tolerance and be susceptible to frost damage.

In summary, when the leaves of the persimmon tree fall off, the growth and fruit yield of the persimmon tree may be negatively affected. Therefore, in order to maintain the health and high yield of persimmon trees, we should try to avoid leaf drop or replenish nutrients and protective measures in time to ensure that the tree can grow and develop normally.
