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 leaf stems of Chinese cabbage from being detached, and relates to the technical field of fruits and vegetables storage. The storage method includes the following steps: (1) pre-cooling the harvested Chinese cabbage to 0 + / - 0.1 DEG C while performing fumigation of 1-methylcyclopropene to obtain pre-treated Chinese cabbage; (2) placing the pre-treated Chinese cabbage in a fresh-keeping storehouse for keeping fresh at the control temperature being 0 + / - 0.1 DEG C, laying a wet sandy layer on the ground in the fresh-keeping storehouse, and placing an ethylene absorbent on the surface of the wet sandy layer. Compared with the prior art, when the storage method is used for keeping fresh for 160 days, the detaching rate of the leaf stems isreduced by 5.23 times and the weight loss rate is reduced by 3 times, the fresh-keeping effect of Chinese cabbage storage is significantly improved and the detaching rate of the leaf stems and the weight loss rate are reduced.

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...
