The causes and control methods of the latest abnormal fruit of eggplant

When eggplant is planted, the phenomenon of abnormal fruit often occurs, which seriously affects the quality and yield of eggplant. Some abnormal fruit is small and hard, without any commodity value and edible value, which has a great impact on economic benefits. So what is the reason for the abnormal fruit of eggplant? Let's take a look.

1. Excess fertilizer and water

The main reason for the abnormal fruit of eggplant is the abnormal development of floral organ. In the case of low temperature or excessive watering and fertilization at flowering stage, the plant will be overnourished, resulting in exuberant cell division, resulting in deformed fruits such as Gemini eggplant and flat eggplant. In the case of overgrowth of the plant, the stems and leaves will take assimilation as a preemptive clean, resulting in the phenomenon of abnormal fruit caused by insufficient nutrition of the fruit.

Prevention and control methods: in the flower and fruit stage, we should pay attention to the excessive irrigation of fertilizer and water, so as not to cause the overgrowth of the plant. for the plants with exuberant growth, we should take measures to control the growth of the plants, so that the stems and leaves will not seize the assimilates and ensure the normal growth and development of the fruit.

2. Improper watering

In the later stage of fruit development, if there is a lack of water transported by the plant to the fruit in a dry environment, the fruit will stop expanding and the fruit surface will not be glossy. However, if there is drought during expansion and flood irrigation in the later stage, the fruit will expand rapidly, but the peel can not keep up with the expansion rate of pulp, and the phenomenon of fruit cracking will occur.

Prevention and control methods: water management is very important when the fruit is expanding, we should pay attention to the change of weather and water in time during drought, but it is not suitable to be irrigated by heavy water, but it is suitable to be irrigated with small water drop.

3. Improper use of hormones

In greenhouse cultivation in winter and spring, due to low temperature and insufficient light, the phenomenon of flower and fruit drop is more serious, so hormone dipping method is often used in production to reduce flower and fruit drop and improve fruit setting rate. However, if the concentration of hormone is too high or used at high temperature, it will lead to poor fruit growth and abnormal fruit.

Prevention and treatment: to reasonable use of hormones, control the concentration, in addition, do not use hormones at high temperature.
