What causes deformed eggplant fruit? Causes and control methods
When growing eggplants, deformed fruit often appears, and deformed fruit seriously affects the quality and yield of eggplants. Some deformed fruits are small with hard flesh, have no commercial value or edible value at all, and have a relatively large impact on economic returns. So what causes deformed eggplant fruit? Let's take a look.
1. Excess fertilizer and water
The main cause of deformed eggplant fruit is abnormal floral organ development. When the flowering period encounters low temperatures or excessive watering and fertilizing, the plant becomes over-nourished, causing vigorous cell division, which leads to deformed fruits such as twin eggplants and flat eggplants. When the plant grows too vigorously, the stems and leaves will take up all the assimilates, causing insufficient nutrition in the fruit and resulting in stiff fruit and deformed fruit.
Control methods: Pay attention during the flowering and fruiting period of the plant, and do not apply excessive irrigation and fertilizer, so as to avoid excessive vegetative growth. For vigorously growing plants, measures to control vigorous growth should be taken so that the stems and leaves will not take up the assimilates, ensuring normal fruit growth and development.
2. Improper watering
In the later stage of fruit development, if a drought environment is encountered and the plant transports insufficient water to the fruit, the fruit will stop expanding and the fruit surface will be lusterless. However, if drought is encountered during expansion and then flood irrigation is used later, the fruit will expand rapidly, but the skin cannot keep up with the expansion speed of the flesh, resulting in fruit cracking.
Control methods: Water management is extremely important during fruit expansion. Pay attention to weather changes, and water in time during drought, but flood irrigation should not be used; small-amount drip irrigation is preferable.
3. Improper use of hormones
During greenhouse cultivation in winter and spring, due to lower temperatures and insufficient light, flower and fruit drop is relatively serious, so the method of dipping flowers with hormones is often used in production to reduce flower and fruit drop and increase the fruit-setting rate. However, if the hormone concentration used is too high or it is used during high-temperature periods, it will lead to poor fruit growth and the appearance of deformed fruit.
Control methods: Use hormones reasonably and control the concentration well. In addition, hormones must not be used at high temperatures.
