Eggplant is one of the common vegetable varieties in our life. With the continuous development of greenhouse technology, eggplant cultivation in greenhouses is becoming more and more common. However, the cultivation of eggplants in greenhouses is not so smooth. Recently, some growers asked: “The eggplants were planted in greenhouses, and some of the eggplants were found to be whitened. What is the reason? What are the control measures?†The following is a small series of this issue and everyone. Let me explain it. Reasons for whitening part of eggplant in greenhouse 1, the greenhouse temperature is too low When the plant encounters a low growth temperature, it will lead to the conversion of lycopene in eggplant, and the eggplant will appear white. 2. insufficient light Eggplant is a hi-light plant. Insufficient light will cause the plant to grow thinly, and the yield will also make the fruit of the plant lighter and whiter. In particular, low light and rainy days can increase the phenomenon of poor fruit coloration. 3. Excessive use of nitrogen fertilizer. Plants grow vigorously and their leaves are large, which can lead to insufficient light in the fruit trees. Especially in the late growth stage, excessive use of nitrogen fertilizer will aggravate the above situation. Prevention 1. Adjust the temperature of the greenhouse Adjust the greenhouse temperature to the optimum temperature, the daytime temperature range is 25-30 degrees Celsius, and the nighttime temperature is 16-20 degrees Celsius. 2. Increase lighting Under the premise of ensuring the temperature, the lighting conditions of the greenhouse are improved, and the light transmission conditions of the greenhouse are strengthened. 3. Rational fertilization In the period of vigorous growth, reduce the application of nitrogen fertilizer, if the plant grows badly, you can use foliar fertilizer. When fertilizing, pay attention to the mixed application of NPK fertilizer and reasonable ratio. The above is the reason why the eggplant whitening in the greenhouse and the prevention and control measures are arranged by Huinong. I hope to help everyone.
