What causes navel orange fruit drop? Detailed explanation of preventive measures

Navel oranges occupy a large share of China's fruit, its price is not high but the taste is excellent, so market demand is still quite large, but during the mature harvest period of navel oranges, many problems are still encountered, such as fruit drop. So what causes navel orange fruit drop? Let's take a look together.

I. Causes of navel orange fruit drop

1. Fruit cracking

Fruit drop caused by fruit cracking is due to the navel orange tree's nutrition being unable to keep up, resulting in reduced immunity. Fruit cracking can be solved through fertilization, watering and light. This is generally caused by improper management by fruit growers, and many fruit growers often encounter it during production.

2. Sunscald

Fruit drop caused by sunscald generally occurs in summer. In summer, the light is very intense, and stimulation by light causes the fruit to drop, so in summer appropriate shading treatment is needed to reduce the sunscald area as much as possible.

3. Pests and diseases

Fruit drop caused by pests and diseases is a common occurrence, because improper management leads to the fruit tree being infested by pests and diseases, and over time the branches and leaves of the fruit tree wither, making fruit drop a common phenomenon. In summer or during the picking period, pests and diseases can cause fruit drop, so fruit growers should prepare pesticides in advance to prevent pests and diseases.

II. Preventive measures

1. Reasonable fertilization

Reasonable fertilization can improve the immunity of the fruit tree and enhance its disease resistance. Currently, organic fertilizers on the market all contain nutrients. Regular fertilization of the fruit tree can not only promote its growth and development, but also play a role in keeping it warm.

2. Improving the soil

The soil of navel orange trees needs to be regularly turned over and loosened. The organic matter in the soil can only be absorbed by the navel orange tree through loosening. In addition, the method of earthing up can also be used to promote the root system's absorption of nutrients.

3. Preventing sunscald

After the fruit tree sets fruit, bagging can be carried out. This can not only reduce the infestation of pests and diseases, but also effectively prevent sunscald. When pesticides are sprayed to control pests and diseases, bagging can also provide protection, will not cause pesticide residues on the fruit tree, and can gain consumers' trust.

4. Spraying pesticides

Pesticides must be used to prevent and control pests and diseases. The number of sprays can be reduced but they cannot be completely omitted. They can effectively reduce pest and disease infection. Once pests and diseases are well controlled, navel orange fruit drop will naturally decrease.
