Eggplant empty bubble fruit control

The peasants who grow summer quail eggplant have been very annoyed recently because this year's aubergine first appeared to be rotten fruit and dead trees. Now that it reflects the empty pods of aubergine, it is not clear why it was formed. The physiology of eggplant is described as follows:

First, the symptoms

Eggplant vacuole fruit, often seen in the off-season cultivation process, eggplant fruit berry, flowering and fertilization after the development of the ovary developed, the pulp has a peel and placenta and pith and other components, in which the placenta is particularly developed by the sponge tissue The composition is used to store nutrients and moisture and is a portion for consumption. Convex fruit from the appearance of the surface, the surface is not smooth, there is a sense of concavity, light weight, soft hair by hand, after the vertical section can be seen between the pulp and peel empty or vacuoles.

Second, the cause of the disease

One is excessive fertilization, especially the excessive application of nitrogen fertilizer causes over-exposure; the second is poor soil, low temperature, lack of light, and weak growth; Third, improper temperature management. The temperature difference between day and night is small, especially if the night temperature is high, the fruit has too little nutrient reserve and the fruit grows poorly. Fourth, the hormone is not handled properly. If the concentration is too high or the flower is too small, the treatment is too early and the eggplant is prone to concavo-convex.

Third, control methods

1. Select the tightly-packed flesh and plant the round eggplant variety with a small chance.

2, formula fertilization, do not partial nitrogen fertilizer, watering do not suddenly dry and damp.

3, the correct use of anthers.

In short, the reason why the eggplant fruit is forming vacuole fruit is that the fruit is obstructed during the process of enlargement. Therefore, in the eggplant fruiting period, strengthening the cultivation and management is to promote the normal growth and development of the fruit, it will certainly reduce the risk of the incidence of vacuoles.
