There are many malformed fruits in the sheds inside the shed, resulting in reduced yields. Its main causes are as follows: 1. The use of hormones to deal with the time of the flower is inaccurate. Hormone treatment of flowers the best time only 3 days, that is, the day of flowering and 2 days before opening, early processing easy to form a simple eggplant. Countermeasures: When eggplant flowers all become purple and open for a total of 3 days, hormone treatment can be used, but the best day to open the treatment. 2. The hormone concentration is too large and it is easy to form deformed fruit. Countermeasures: Hormones usually have a concentration of 0.003% for flowers, but they should be handled flexibly. They should be slightly lower when the temperature is high, and slightly higher when the temperature is low. When the outside temperature is lower than 15 °C, the concentration of 0.004% ~ 0.005% is appropriate. 3. The weaker flowers are thin and pedicels are thin, which means that if hormones are used, they will form a stale fruit. Countermeasures: eliminate small seedlings and stiff seedlings when planting, select strong seedlings; remove the door eggplant flowers, artificially extend the growth period, while increasing fertilization material, promote root growth and strong, according to the growth of the fruit after sitting according to plant growth, the implementation of limited fruit management. 4. The flowers that are grown by the proteotrophic vegetative growers, even if they are treated with hormones, will also form malformed fruits. Due to the excessive growth of nutrients, the nutrient produced by the leaves is competed by the stems and leaves, inhibiting reproductive growth. Countermeasures: In the right time, the seedlings of the seedlings in the seedlings should be controlled in the right time, and the water and fertilizer should be controlled appropriately during the seedling stage, and the cultivating soil should be used to turn the vegetative growth into reproductive growth. Spraying brassin can also balance the vegetative and reproductive growth of eggplant. 5. Treating flowers with hormones under high temperature conditions is easy to form deformed fruit. Countermeasures: Temperature should exceed 30°C. Flowers should be stopped. Flowers that are open on the day should be processed at 30°C or less. For unopened purple flowers, treatments that can not be finished before 10am can be processed at 4pm.
