What about the latest citrus fruit drop before harvest?

Citrus blossoms and fruits, when they are almost ripe, it is the time for fruit growers to harvest hard for a year, but many growers find that their fruits begin to fall constantly, which is a big loss to farmers. So what causes citrus fruit drop before harvest? Let's get to know each other.

I. Reasons

Citrus fruit drop before harvest may be due to insufficient nutrition of the tree, providing less nutrition to the fruit, so it is easy to drop fruit; second, in continuous high temperature or high temperature climate, fruit drop before harvest will also occur in some areas. In addition, after the fruit matures, the fruit stalk is also very easy to separate, and in the later stage, when it rains heavily, it will be dropped by rain, or the fruit absorbs too much water and drops fruit. If the light is too poor, it will also affect the synthesis of nutrients, and it is also easy to cause malnutrition and fruit drop. In the later stage, drought and water shortage will also cause large fruit drop. When diseases and insect pests are serious, fruit drop will also occur.

II. Prevention

1. Fertilization

Sufficient fertilizer should be applied at every stage of citrus growth. During the fruiting period, topdressing should be applied continuously until after fruit picking to ensure sufficient nutrients for fruit growth and development. At the same time, we should also pay attention to the supply of trace elements, so as not to cause fruit drop due to deficiency symptoms.

2, pruning

Trim the crown structure at any time to ensure good light transmittance and meet photosynthesis. Trim off redundant branches. Some dead branches, interspersed with internal branches, drooping branches and disturbing crown branches must be pruned off. This saves a lot of nutrients. During the growth period, it should be pruned at any time, and nutrients can be accumulated to supply the fruit.

III. IMPROVEMENT

1. Weather

When encountering high temperature weather, you can spray water in the orchard in the morning and evening to cool down, or you can also pick it in advance, pay attention to the change of weather, ditch drainage in time before rain, so as to avoid ponding, so as to facilitate rainwater drainage, and if it is dry, water it in the afternoon or evening to keep the soil moist until it starts to rain, and the weather will stop.

2, pest control

A common disease is anthracnose, when the disease occurs, a disease spot appears on the fruit, and gradually expands. When it rains, half of the fruit will fall after decay. If the disease spot carries leaf stalks, it is easier to fall. Some fruits eaten by insects, such as fruit flies, are intact on the outside, but broken inside, they will fall by themselves. Prevention is needed in advance, and timely prevention and control are needed after occurrence.
