Chinese cabbage is a vegetable type that is comfortable, warm and resistant to heat but not heat-resistant. High temperature and high humidity are highly perishable. Insufficient water supply in the early period and excessive water supply in the later period can cause cracking of the leaf ball. In the later period of the ball-bearing period, if nitrogen fertilizer is applied in excess, the external leaf ball will be basically shaped and the interior will still grow rapidly. The phenomenon of cracking will appear in the ball. Harvesting too late or not in time will lead to over ripening of Chinese cabbage, and it will also cause cracking of leafballs. Long-distance transportation or storage of preserved Chinese cabbage can generally only be harvested at a time of maturity.
For the growth of Chinese cabbage should be reasonable watering, fertilization, pay attention to the use of nitrogen, phosphorus and potassium and calcium fertilizer, timely removal of water in the event of heavy rain, control of vegetable fields, wet and dry, timely harvest, do not excessive use of hormone products, As long as the measures are properly implemented, the occurrence of cracking of Chinese cabbage can be reduced.
