What is the cause of the fissure in the greenhouse?
Answer: Cracking ball refers to cracking of Chinese cabbage leaf ball. If the water supply in the early period is insufficient, excessive water supply in the later period will cause cracking of the leaf ball. In the later period of the ball, the top dressing is continued, that is, the inner leaves continue to grow after the top dressing. The size of the outer leaf ball has been shaped, and the leaf ball cracking may also be caused by the inner leaf ball expansion pressure. Can pay attention to the uniform water supply in the cultivation, the fertilizer should be stopped in the later period, if it can not be listed, it can be cut roots to prevent the root system from absorbing water and nutrients.
