Problems solved by technology

But SiO 2 The bactericidal ability is weak, and it is difficult to play a role against botrytis cinerea; the lack of timely pre-cooling after harvest, the lack of heat preservation in logistics, and the post-harvest loss are still relatively large

Embodiment Construction

[0041] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0042] A multi-field anti-corrosion and fresh-keeping method for grape microenvironment, the key technical scheme is as follows:

[0043] 1 Pre-harvest preservative intervention for grapes

[0044] 1.0mmol L on the surface of the fruit every other week within 1 month before harvesting -1 Melatonin, 5mmol L -1 γ-aminobutyric acid (GABA), 20mg L -1 Spermidine, 2.0mmol L -1 A compound anti-aging inhibitor composed of GA (gibberellin) synthesis inhibitors, which can reduce the activity of PAL enzyme, inhibit the activity of chitinase and cellulase, and slow down the degradation of chitin and cellulose.

[0045] The way of spraying 1-MCP solution 1 day before harvesting (0.5% Tween-20+1.5% polylysine+0.5% bamboo vinegar+0.5% peach gum+2% egg ...

Abstract

The invention relates to a microenvironment multi-field preservative and fresh-keeping method for grapes. The method comprises the following steps of (1) performing preservative intervention before grapes are picked; (2) pre-cooling a cold-chain logistics microenvironment temperature control box in time; (3) carrying out low-temperature high-pressure argon controlled atmosphere storage in the microenvironment controlled atmosphere box; and (4) carrying out intermittent atomization preservative treatment during storage. The fresh-keeping method is scientific and reasonable in design and efficient in fresh-keeping effect, the key technologies of preharvest corrosion prevention, cold-chain logistics, microenvironment controlled atmosphere and intermittent atomization corrosion prevention in the storage period are organically combined, the comprehensive grape fresh-keeping technology from preharvest to post-harvest storage is provided, efficient corrosion prevention of grapes is achieved, and the excellent quality is kept; and taking sun rose grape (a grape variety) for example, by using the fresh-keeping method, the storage period can reach 50 days, and the intact fruit rate is 98.6%.

Description

technical field [0001] The invention belongs to the field of post-harvest storage and fresh-keeping of agricultural products, and relates to post-harvest grape fresh-keeping technology, in particular to a multi-field anti-corrosion and fresh-keeping method for grape microenvironment. Background technique [0002] Grape planting is mostly concentrated in Xinjiang, Shandong, Hebei, Yunnan, Liaoning, Zhejiang, Henan and other places. The planting area is 12 million mu, and the output in 2019 is 10.8 million tons, ranking first in the world. Grapes are not only delicious, but also have high nutritional value. However, mechanical damage, microbial infection, and browning of fruit stems often occur in the postharvest storage and logistics process of grapes, resulting in threshing and rot, and the postharvest loss rate is as high as 20%-30%. [0003] Traditional grape preservation technology mainly uses SO 2 Combined with low temperature, relying on gas SO 2 Contact with water o...
