The author recently discovered in Jitai Township, Shouguang City that some sheds and eggplants had many malformed fruits, resulting in reduced yields. Its main causes are the following:
1, the use of hormones to deal with the time spent on the flowers are not grasped and the best time to form a fruit hormone hormone treatment only 3 days, that is, the day of flowering and 2 days before opening, early processing is 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. Excessive hormone concentration is likely to cause malformation. Countermeasures: Hormones normally require 0.003% of the flower density, but should be handled flexibly. When the temperature is high, it is slightly lower; when the temperature is low, it is slightly higher. When the outside temperature is lower than 15 °C, the concentration of 0.004% ~ 0.005% is appropriate.
3, the relatively weak plants opened thin flowers, pedicels fine, that is, the use of hormone treatment, will also form a stalemate countermeasures: the elimination of seedlings and stiff seedlings when planting, select strong seedlings; remove the door eggplant flowers, artificial extension of the growth period, Simultaneously increase fertilization material, promote roots and grow strong pods, and implement limited fruit management according to plant growth status for fruit that is sitting later.
4. The flowers opened by the proteobacteria who grow too nutrients are treated with hormones to form malformed fruits. Because nutrient growth is too prosperous, the nutrients produced by the leaves are scrambled by the leaves and stems, 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, in the high temperature conditions with hormones to deal with flowers easily deformed fruit Countermeasures: Temperature exceeds 30 °C should stop the treatment of flowers, the opening of the day the flowers are processed below 30 °C, is not open to the change of purple flowers, 10:00 The pre-processing can be processed after 4 pm.
