The appearance of eggplant affects its commercial value and causes great losses to the vegetable farmers. When the temperature of the solar greenhouse is too low, the eggplant often has capsules, and the cockroaches are mainly concentrated at the front end of the fruit, which is a protrusion with a height of 0.5 to 1 cm. When the fruit is opened, it is found that there is a large gap between the peel and the flesh.
Eggplant fruit pimple occurs because the incidence of
The temperature of the shed is too low, especially in special weather. When the shed temperature is lower than 25 °C and the night temperature is lower than 15 °C for 3 consecutive days, the root activity is weakened, the absorbed nutrients can not meet the normal growth demand of the fruit, and the plant's resistance to stress is reduced. It is prone to fruit. When the weather is fine, although the outside temperature is very low, as long as the light is good, the temperature inside the shed rises very quickly after the grasshopper is uncovered. Since the peel is first heated, the temperature of the peel and the pulp varies greatly between 9 and 10 am. In such a state for a long time, the growth speed of the peel is bound to exceed the flesh, which will also cause the fruit to grow. In addition, if the amount of gibberellin is too large, it often leads to a rapid development of the fruit after flowering, and the resistance to the outside world is deteriorated, and the fruit is prone to occur.
Eggplant appeared in the prevention of
For these reasons, it is recommended to pay attention to the following points during management: pay attention to the insulation of the shed, especially to keep the night temperature not lower than 15 °C, so as to avoid the deterioration of the root activity. On a sunny day, the shed will be ventilated one hour after pulling the grass hoe, giving the shed a slow warming process, so as not to cause the temperature of the fruit to change drastically. Pay attention to the application of foliar fertilizer. Foliar fertilizers that enhance the plant's resistance to stress, such as full-nutrient foliar fertilizer or chitin.
