Symptoms:

Eggplant fruit shape is not correct, do not live long, that is, stiff eggplant. In addition, it will also produce deformed fruits such as calyx cracked fruit, partial flat fruit, hairy edge fruit and so on. The cause of abnormal fruit is mainly due to the poor quality of seedlings, which is related to the management of bed soil, temperature and wet light. When the day and night temperature is too high, the assimilation nutrient consumption increases, resulting in the deterioration of seedling quality. If the light is insufficient, the growth and development is slow, the period of flower formation and flowering is delayed, and the quality of flower is decreased. When the temperature is lower than 17 ℃ and higher than 35 ℃, the fertilization of eggplant is blocked and the pollen germination slows down. Even if the pollen falls on the pistil and the pollen tube elongates poorly, the malformed fruit is formed.

Prevention and control methods:

The main results are as follows: 1. In greenhouse cultivation, the minimum temperature during the seedling period is kept at 14-15 ℃, daylight should be increased, the greenhouse temperature should be controlled below 30 ℃, and ventilation should be carried out in time to prevent the occurrence of stiff eggplant caused by high temperature.

2. Eggplant likes strong light. Using glass or fully transparent plastic film when raising seedlings is beneficial to improve the quality of seedlings, but the temperature above 40 ℃ will not germinate.

3. Promote compost made by organic active fertilizer or enzyme bacteria retting, adopt formula fertilization technology, spray plant growth regulator, foliar fertilizer and so on to promote plant growth and water timely and appropriately.
