A Detailed Guide to the Latest Winter Cellar Storage Management Methods for Napa Cabbage
Winter is the harvest season for napa cabbage, and many people store napa cabbage in winter, especially in northern regions. When storing napa cabbage, the biggest fear is rot and loss of outer leaves, and these are all caused by improper storage. So how should napa cabbage be stored in winter? Let's take a look together.
1. Early-stage management
Generally, napa cabbage is not put into the cellar for storage immediately after harvest. Instead, it is put into the cellar when the temperature drops around Major Snow, and 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 direct contact between the cabbage and the ground and reduce the possibility of rot. When stacking the cabbage, do not pack 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 methods 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
From after Major Snow to before the Beginning of Spring is the coldest period of the climate. At this time, it is generally necessary to turn the cabbage once every 15-30 days, and methods of ventilation and short ventilation should also be adopted according to the temperature of the cellar. Generally, ventilation is carried out in the morning when the temperature is relatively high, and the windows can be closed at 4-5 p.m. The principle is to keep the napa cabbage in the cellar from freezing, and to rely on skylights and air holes to release unpleasant odors.
3. Late-stage management
After the Beginning of Spring, pay attention to releasing heat and preventing freezing. At night and in the early morning and evening, keep it warm in winter, and at the same time the skylight should avoid direct sunlight, so as to prevent sunlight from causing excessively high temperatures in the cellar. At noon, when the temperature is relatively high, ventilate in time to prevent outside hot air from flowing into the cellar. In addition, before storing napa 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 clear rotten leaves out of the cellar.
