The change of long eggplant from purple to red is mainly caused by rising temperatures, strong lighting and improper fertilization. To prevent the long purple egg from turning red, note the following: First, regulate the temperature inside the shed. Temperature not only influences the development of flower bud differentiation, but also affects the production and transportation of lycopene. Especially in the current situation where the temperature gradually rises, the temperature of the shed is higher, so it must be properly ventilated. The daytime temperature is controlled at about 28°C and about 15°C at night, so it will not affect the formation of pigments, and it is beneficial to the accumulation of organic nutrients. Second, appropriate amount of leaves to prevent excessive light. When the leaves are picked, they should be removed as much as possible. However, they should not be picked too much at one time. Excessive picking of the leaves causes strong direct sunlight to cause red eggplant. Moreover, since the upper part of the plant receives more sunlight, the replanting method of the replanting can be adopted for the eggplant with a relatively high part of the result and the light is directly irradiated, thereby reducing the length of the long eggplant and avoiding direct sunlight. Again, the appropriate amount of potash is used to promote the coloring of the fruit. The results later, if you do not pay attention to supplemental potassium, the probability of red eggplant will be much greater. Therefore, the use frequency of potash fertilizer can be appropriately increased at the stage of red eggplant, for example, the application of high-potassium water and fertilization in the blinking period and the rapid fruit expansion period can effectively reduce the long purple color of purple eggplant.
