The reason why the apple tree is old? what if all the fruit of the apple tree has fallen?

Experienced fruit growers all know that the higher the fruit setting rate of apple trees during flowering, the greater the yield of apples during harvest. But in the fruiting period, some fruit farmers will find that their apple trees grow old, and it doesn't matter if they don't have a large quantity, because a large amount will affect the income of the fruit growers. Today, the pro-agricultural network will explain to you the reason why the apple tree has lost its fruit, and how to do it.

First, the reason why apples fall from apple trees

In fact, the phenomenon of apple tree fruit drop is not uncommon, because the apple tree itself has the phenomenon of fruit loss, which is a normal growth process, but there are also fruit loss caused by unhealthy reasons, so let's follow the pro-agricultural network to learn about it.

1. Natural fruit drop

Apple trees will naturally drop fruit in the fruit period, which is one of its growth habits, so don't worry too much. In general, there are two peaks of apple tree fruit drop, the first is about 10 days after flowering, and the second is from July to August.

two。 The tree is too prosperous.

Excessive growth of apple trees will also lead to fruit loss, which is caused by improper use of fertilizer. Apple trees may lose fruit because of excessive nitrogen fertilizer or lack of phosphorus and potassium, resulting in imbalance of carbon and nitrogen in the tree, resulting in excessive vegetative growth. vegetative growth and reproductive growth imbalance, resulting in a large number of fruit drop It is also possible that the apple trees bear little fruit and have no place to supply a large amount of nutrition, so they have to be transported to the vegetative branches to grow, which will also cause the trees to be too prosperous.

3. Fruit drop caused by diseases and insect pests

This situation needs to be observed. If the fallen apples rot, or if the trunks of the apple trees rot, we should consider whether there are diseases and insect pests in the orchard, such as rot, ring disease, anthrax, and so on. Will cause the apple tree to drop the apple.

What if an apple falls from an apple tree

In order to prevent apple trees from falling fruit, we must first analyze the specific reasons for the loss of fruit, and then prescribe the right medicine to the case. We should not take measures blindly. Let's take a look at the details below.

1. Angle of branch opening

Change the direction of the upright apple tree branches by supporting and pulling, so that the branches are dispersed, which can enhance the ventilation and transparency of the apple tree, restrain the excessive growth of the branches, and make the apple grow better during the fruit setting period.

two。 Except cute and skillful to pick the heart.

Extremely heavy coring can effectively reduce the consumption of nutrients and make nutrients accumulate on early-growing strips, thus accelerating the growth of young fruits and avoiding fruit drop caused by lack of nutrients.

3. Rationally replenish fertilizer and water

Apple blossom and fruit period do not encourage the tree potential, to gradually reduce ammonia fertilizer, increase the amount of phosphorus and potassium fertilizer, pay attention to watering, this can promote fruit expansion.

4. Use foliar fertilizer frequently

During the young fruit period, amino acids, rare earths or other trace fertilizers are sprayed on the leaves every 7 to 10 days. The spray should be meticulous, uniform and thoughtful. The effect of foliar fertilizer is obvious, but after all, the fertilizer effect is limited, which is only an auxiliary measure and can not replace soil fertilization.

5. Spray anti-falling element

Spraying naphthylacetic acid or other antidepressants after anthesis has a significant effect on promoting fruit setting and reducing physiological fruit drop. It should be noted that the concentration should be strictly applied in accordance with the instructions, and the dosage should not be increased or reduced at will.

6. Pest control

If the apple tree trunk is rotten, it is rotten disease, the effect of methylthionaphthalene acetic acid is good; if it is fruit rot, it is ring disease, anthracnose, methyl carbendazim, tebuconazole, tebuconazole and so on.

The above are the reasons for the fruit loss of apple trees brought by the pro-agricultural network and the relevant prevention and control measures. Apple trees only blossom and bear fruit once a year, and most fruit growers do not want their fruit trees to drop too much. I hope that by reading this article, it can provide some help for fruit growers.
