When the temperature of the solar greenhouse is too low, the eggplant often appears pods, and the pods are mainly concentrated on the front of the fruit, which is represented by a 0.5-1 cm high protrusion. Breaking through the fruits, it was discovered that there was a large gap between the peel and the flesh in the area where the clams were grown.
The etiology of the shed was too low, especially in the case of special weather. When the shed temperature was below 25°C for 3 days and the night temperature was below 15°C, the root activity was weakened and the nutrients absorbed could not meet the normal growth requirements of the fruit. The ability to reduce, prone to results. When the weather is fine, although the outside temperature is very low, as long as the light is good, the temperature in the shed rises quickly after the rake is opened. Since the skin is heated first, the temperature of the peel and the flesh is very different between 9 and 10 am. For a long period of time, the growth rate of the peel will inevitably exceed that of the flesh, and it will also cause the fruit to grow long. In addition, if the amount of gibberellin is too large, it often results in rapid development of fruit after flowering, and the resistance to the outside world is deteriorated, and it is also easy for fruit to appear.
Preventive Measures For these reasons, it is advisable to take care of the following when managing: Pay attention to the insulation of the greenhouse, especially keep the temperature at night not lower than 15°C, so as to avoid deterioration of the root activity. On sunny days, open the sheds one hour after they open the grass rakes and give the sheds a warming-up process to avoid drastic changes in the fruit temperature. Pay attention to the application of foliar fertilizer. It can be sprayed with full-foliage foliar fertilizer or chitin to enhance the resilience of the plant leaf fertilizer.
