How to manage Chinese cabbage in winter cellar storage? These methods are very practical
Winter is the harvest season for Chinese cabbage, and many people store Chinese cabbage in winter, especially in northern regions. When storing Chinese cabbage, the biggest fear is rot and leaf loss, and these are all caused by improper storage. So how should Chinese cabbage be stored in winter? Let's take a look together.
1. Early-stage management
Generally, Chinese cabbage is not put into the cellar for storage immediately after harvest. Instead, it is put into the cellar when the temperature drops around the time of Major Snow. The time of putting it into the cellar should also be chosen at night. Wooden boards can be placed in the cellar to stack the cabbage, so as to avoid the cabbage directly touching the ground and reduce the possibility of rot. When stacking the cabbage, do not stack it too tightly; keep enough gaps for ventilation. After storage, the cabbage should be turned frequently. Generally, in the initial period, it is turned three times in a row, and the method of turning quickly without removing leaves or turning quickly while removing few leaves can be used. When turning the cabbage, it is best to wear gloves, which can reduce the effect of body temperature on the cabbage, and at the same time remove rotten leaves. It is best not to use iron tools; bamboo knives can be chosen instead. At the same time, pay attention to ventilation and adjust the humidity in the cellar.
2. Mid-stage management ⟧7⟧From after Major Snow to before Start of Spring, this is the coldest period of the climate. At this time, it generally needs to be turned once every 15-30 days, and at the same time, according to the temperature of the cellar, the methods of ventilation and short ventilation should be adopted. Generally, ventilation is carried out in the morning when the temperature is relatively high, and the windows can be closed at 4-5 pm, with the principle of keeping the Chinese cabbage in the cellar from freezing, relying on skylights and air holes to release bad odors.
From after Major Snow (around December 7) to before the Start of Spring (around February 4), when the weather is at its coldest, the cabbages generally need to be turned over once every 15-30 days, and at the same time ventilation, including brief ventilation, must be carried out according to the temperature of the cellar. Ventilation is generally done in the morning when the daytime temperature is relatively high, and the windows can be closed at 4-5 pm to keep the cabbages in the cellar from freezing, relying on skylights and air holes to release unpleasant odors.
3. Late-stage management
After Start of Spring, pay attention to releasing heat and preventing freezing. At night and in the early morning and evening, keep warm in winter, and at the same time the skylights should avoid direct sunlight, so as to prevent sunlight from causing the temperature in the cellar to become too high. At noon when the temperature is relatively high, ventilate in time, so as to prevent outside hot air from flowing into the cellar. In addition, before storing Chinese cabbage, it should be sun-dried to reduce surface moisture. When cutting the cabbage, pay attention to mechanical damage, and at the same time promptly clean rotten leaves out of the cellar.
