In early spring, preserved cabbage is often prone to leaf ball cracking, which not only damages the visual appeal and commercial value of the vegetable but also increases its vulnerability to diseases. This can lead to problems during storage and transportation, reducing overall yield and profitability.
According to experimental studies, the occurrence of leaf ball cracking is influenced by several factors. While it is partially related to the variety of cabbage used, it is more significantly affected by water management. Interestingly, it has no direct connection with fertilizer application. If the cabbage receives insufficient water, the head will remain small and underdeveloped. On the other hand, excessive watering can cause the outer leaves to crack, leading to further damage and spoilage.
To minimize this issue, farmers should implement the following effective measures during cultivation and management:
1. Choose varieties that are resistant to leaf ball cracking, such as Zhong Gan No. 11, which has been proven to perform well in preventing this problem.
2. Practice scientific irrigation based on the plant’s growth stage. During the seedling phase, the water requirement is relatively low. However, once the cabbage enters the head-forming stage, it needs more consistent moisture. The soil moisture content should ideally be maintained between 75% and 85% to support healthy development without causing overwatering.
3. Harvest the cabbage at the right time. Delaying harvest can result in the head breaking apart, making it unsuitable for sale. Even if market prices are not favorable, timely harvesting is crucial to maintaining quality and avoiding losses due to cracking or rotting.
By following these practices, growers can significantly reduce the risk of leaf ball cracking, ensuring better quality, longer storage life, and higher market value for their preserved cabbage.
