Early prevention of eggplant capsules

The temperature of the greenhouse is too low, especially when it encounters special weather. When the greenhouse temperature is lower than 25°C during the three days and the night temperature is lower than 15°C, the activity of the root system is weakened and the nutrients absorbed cannot meet the normal growth requirements of the fruit. Decreased, long eggplant prone to fruit growth. 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 flesh differ greatly between 9:00 am and 10:00 a.m. 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 is deteriorated, and it is also easy for fruit to appear.

For these reasons, it is recommended to pay attention to the following points in the management: 1 pay attention to the greenhouse insulation, in particular, keep at least 15 °C at night, so as not to cause deterioration of the root activity. When the special weather is not open to open the shed, insulation measures should be taken, such as hanging light bulbs inside the shed. 2 On sunny days, one hour after pulling out the grass rake, the greenhouse should be ventilated, giving the shed a warming-up process to avoid drastic changes in the temperature of the fruit. 3 pay attention to adjust the amount of gibberellin anther, generally 2 to 3 ml against a pound of water can be. 4 Pay attention to the application of foliar fertilizer. It can spray full-foliation foliar fertilizer or chitin to enhance the resistance of the plant leaf foliar fertilizer.
