Embodiment Construction

[0010] Choose autumn green Chinese cabbage for storage, and stop watering 10 days before harvest. After harvesting, Bacheng will naturally dry it in the field for 3 days, remove yellow leaves, rotten leaves and peripheral leaves, and remove vegetable trees with diseases and insect pests. It is packaged in a plastic frame, with the leaves facing the inside and the root facing the outside, and 2 vegetables are placed in the frame. Each frame is packed with 2 layers of 8 vegetables; the frames are stacked according to the font, and there are 5 gaps between the frames. ; Different layers are cross-stacked, and the stacking height is about 10 layers.

[0011] After the warehouse is full, the closed warehouse door uses 1-MCP ethylene inhibitor to fumigate Chinese cabbage, the concentration is 900ppb, and the warehouse door is opened for 12 hours; the warehouse is equipped with an ozone sterilizer, which is turned on once every 10 days, and the time is 1 Hour.

Abstract

The invention relates to a method for retaining freshness of Chinese cabbage in a cold storage. The method comprises the steps of forbidding irrigation 10 days before the harvest of the Chinese cabbage, harmlessly harvesting when the Chinese cabbage is eighty percent maturity; drying the harvested Chinese cabbages in the field; getting rid of diseased leaves, injured leaves and decayed leaves; loading into boxes or putting on shelves; stacking scientifically; performing fumigation treatment on the stacked Chinese cabbage with 1-MCP; storing in a cold storage at a temperature of 0 DEG C; and sterilizing with ozone at regular intervals during storage. The Chinese cabbage can be stored for 3-4 months by the method, with a rotting rate lower than 15%. The storage technology is simple, economical and practical.

Description

technical field [0001] The invention belongs to the fresh-keeping technology of fruits and vegetables, in particular to a fresh-keeping method of Chinese cabbage. Background technique [0002] Chinese cabbage can be cultivated in all parts of my country. It is not only the main vegetable in the winter and spring markets in the northern region, but also can adjust part of the demand in the southern market. Chinese cabbage likes a cool and humid storage environment. The freezing point temperature of the heart leaves is -1.2°C, but the outer leaves start to freeze at -0.6°C, and freezing damage will occur if it is lower than -0.6°C for a long time. In the long-term storage process, the loss of Chinese cabbage can reach 30%-50%. The main reason is that it is detached, followed by rot and natural weightlessness. The cause of debonding is closely related to the ethylene content in the storage environment. When the ethylene content exceeds 2.3×10-7, it can lead to debonding. Th...
