大白菜是我国北方冬春季节的一种主要蔬菜,用量大,食用时间长。北京从11月上旬至第二年4月上中旬,黑龙江省从10月到第二年5月,在这段时期内,主要靠大白菜供应市场。为了保证群众冬春季有鲜嫩的菜吃,贮存好大白菜有重要意义。不忘前提适时收获和入窖是贮藏好大白菜的前提。收获早不仅影响产量,而且也因温度高不利于贮藏;收获过晚易发生冻害,亦不利于安全贮藏。大白菜适宜的收获期是当最低气温降到-5℃以前开始收获,气温降到-5～-6℃时必须收完,当最低气温降到-6～-7℃时为大白菜适量的入窖时间。抓住关键窖内适宜的温度湿度是贮藏好大白菜的关键。大白菜适宜贮藏的温度为0—2℃,又以0—1℃为最适宜温度,最低不能低于-2℃以下,最高不能高于2℃以上。如
Chinese cabbage is a major vegetable in winter and spring in northern China, with a large amount of consumption and long time. Beijing from early November to the second year in April on the middle, Heilongjiang Province from October to the following year in May, during this period, mainly rely on Chinese cabbage supply market. In order to ensure that the masses have fresh vegetables in winter and spring, storing Chinese cabbage is of great significance. Do not forget the premise timely harvest and into the pit is the prerequisite for the storage of Chinese cabbage. Early harvest not only affect the yield, but also because of the high temperature is not conducive to storage; harvested too late prone to frost damage, is not conducive to safe storage. Cabbage suitable harvest period is when the minimum temperature dropped to -5 ℃ before harvest, the temperature dropped to -5 ~ -6 ℃ must be closed, when the minimum temperature dropped to -6 ~ -7 ℃ for the amount of cabbage Into the cellar time. Seize the key temperature and humidity in the pit is the key to storing cabbage. Cabbage suitable storage temperature of 0-2 ℃, and 0-1 ℃ for the most appropriate temperature, the minimum can not be less than -2 ℃ below the maximum can not be higher than 2 ℃ above. Such as
