Embodiment 1

[0021] 1. Harvesting and selection: Harvest the leaf balls to reach the degree of "80% heart" compactness, and select cabbage without old ganglion, swelling and mechanical damage. The purpose is to select high-quality fresh-keeping raw materials.

[0022] 2. Pre-cooling: pre-cool the above-mentioned cabbage to 0±0.1°C within 24 hours after picking, and use 1-methylcyclopropene to place the cabbage at a weight-volume ratio of 0.3-0.4 mg / m at the same time. 3 Carry out fumigation and ventilate after fumigation.

[0023] 3. Storage and preservation: After pre-cooling and fumigation, enter the storage and preservation link, and the preservation temperature is 0±0.1℃. Place a wet sand layer with an area of ​​about 1 / 2-2 / 3 of the floor area of ​​the fresh-keeping warehouse and a thickness of 3.5-4.0cm in the fresh-keeping warehouse. It is required that the water in the sandy soil layer should not overflow. Evenly place ethylene absorbent particles on the surface of the sand layer....

Abstract

The invention provides a storage method for preventing Chinese cabbage from debonding, and relates to the technical field of fruit and vegetable storage. The storage method of the present invention comprises the following steps: (1) pre-cooling the harvested Chinese cabbage to 0±0.1°C, the pre-cooling is also accompanied by 1-methylcyclopropene fumigation to obtain pretreated Chinese cabbage; (2) Put the pretreated cabbage in a fresh-keeping store for fresh-keeping. The temperature in the fresh-keeping store is controlled at 0±0.1°C. A wet sand layer is laid on the ground in the fresh-keeping store, and ethylene is placed on the surface of the wet sand layer. absorbent. Compared with the prior art, when the storage method of the present invention is used to keep fresh for 160 days, the debonding rate is reduced by 5.23 times, and the weight loss rate is reduced by 3 times, which can significantly improve the fresh-keeping effect of Chinese cabbage storage, and reduce the debonding rate and weight loss. Rate.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable storage, and in particular relates to a storage method for preventing Chinese cabbage from detaching. Background technique [0002] Chinese cabbage belongs to Brassica vegetables of the Brassicaceae family. It is native to China and is also known as "heading cabbage", "wrapped cabbage", "yellow bud white" and "jiaocai". It has a long history of cultivation and abundant variety resources. It is one of the vegetable crops with the largest cultivation area in my country at present. In 2017, the planting area of ​​Chinese cabbage was 2.6412 million hectares, and the output was 114.16 million tons. [0003] Due to the high level of physiological metabolism and fast water transpiration of Chinese cabbage, it is easy to lose water and wilt after harvesting. In addition, the seasonality of growth is relatively strong, the listing is relatively concentrated, the contradiction between supply a...
