大白菜在北方的贮藏期长达半年之久,要贮好大白菜,降低菜窖损耗率,必须抓好白菜入窖后的管理工作和防腐措施.菜窖管理工作主要是调整好窖内的温度和湿度。控制温湿度的关键是通风.通风条件好坏,直接影响菜窖内白菜呼吸的强弱和腐烂率的高低。窖藏白菜对通风条件反应敏感,但是,人们往往为了保持窖内温度而忽视通风条件。所以,掌握好白菜呼吸规律的变化与外部因素的关系,对防止 Chinese cabbage storage in the north for up to six months, to storage cabbage, reduce the loss rate of the cellar, we must grasp the cabbage into the pit after the management and anti-corrosion measures.Calcock management is mainly to adjust the cellar Temperature and humidity. The key to control the temperature and humidity is ventilation.Passing conditions are good or bad, directly affect the cabbage cabbage respiration intensity and the rate of decay. Cabbage cabbage is sensitive to ventilation conditions, however, people tend to ignore the ventilation in order to maintain the temperature in the pit. Therefore, to master the relationship between changes in the law of cabbage and external factors, to prevent
