What if the persimmon tree falls fruit?

Persimmon fruit drop is a very serious thing, because persimmon trees are generally higher, when persimmons fall to the ground, persimmons are broken in many cases. So why do persimmon trees lose fruit? It is mainly caused by three aspects, the following pro-agricultural network will take you to understand the causes of these two aspects and their prevention and control methods.

1. Causes of persimmon trees

Persimmon tree fruit drop and itself is also for a certain reason. First of all, its own vegetative growth is too exuberant, resulting in the lack of nutrients in the fruit, in the later stage, the flower pedicel can not bear the weight of persimmon, resulting in falling. This will also happen in the early stage of poor pollination, and in the later stage, the fruit will fall if the fruit is not fully developed. Finally, when persimmons of the same branch grow too much, they grab nutrients from each other after getting bigger in the later stage, and some of the persimmons with poor growth will also lead to fruit drop.

Solution: in the face of vigorous vegetative growth of branches, we have to deal with, some branches and leaves should be properly cut off, so that nutrients can be transported to places where needed. In the initial pollination, we need to observe more, if not ideal circumstances need to carry out artificial pollination, in order to ensure later development. Finally, if the flowers on some branches are too dense or the branches with more fruit grow more slowly than other fruits, they should be removed manually.

2. Environmental factors

Environmental factors can also easily cause persimmon trees to drop fruit. First of all, the lack of water and fertilizer will lead to a serious decline in the health of persimmon trees, when the rescue has a serious loss of fruit, because the tree is unable to maintain the nutrient demand of the fruit. Secondly, if the weather is not ideal for a long time, continue to be exposed to the sun or rain, the growth and development of the fruit will be seriously hindered, unable to grow, and finally can only fall. If the soil in the planting place is too barren, not to mention, persimmon trees are stunted, isn't it normal to lose fruit?

Prevention and control methods: fertilization is fastidious, persimmon trees have different fertility needs in different periods of time, and various trace elements are needed in the initial stage of planting, so it is necessary to apply more farm manure, and in the later stage, in order to ensure the vitality of the fruit, chemical fertilizer is the main method. In the case of heavy rainfall, it is necessary to do a good job in drainage measures, especially its roots, when it is serious, you can set up some items to block the rain in the roots, and when it is hot, it is necessary to ensure the supply of water. If it is hot for a long time, persimmon trees can be sprayed with clear water as a whole to achieve the purpose of cooling. The fertility of the soil in the early stage must be ensured, and it is best to compost for a period of time.

3. Diseases and insect pests

This is one of the more serious aspects of persimmon fruit loss. For example, the most common persimmon stalk worm is one of them. When it is found, it will generally have a large number, causing serious damage to the pedicel of persimmon, reducing or even withering the pedicel. In the end, persimmons can only fall without pulling force.

Control methods: persimmon pedicel insects often occur in summer, around July, which is an important time for persimmon pedicle larvae to begin to metamorphosis. If you find that there are larvae that can be removed manually, the diseased trees can be sprayed with 1000 times of dichlorvos EC to control the disease. Generally spray twice, the interval time is about 20 days.

It is normal for persimmon trees to drop fruit, and persimmons that grow normally will also fall under some external factors. So occasionally drop a few people do not be too nervous, fall more frequently should pay attention to, the need to check whether there is the above situation, so as to prescribe the right medicine. Try not to pass under the persimmon tree during the daily inspection of the orchard to avoid causing unnecessary harm.
