Problems solved by technology

But at present, 1-methylcyclopropene is still limited to post-harvest treatment, and there are few reports on pre-harvest treatment. Li Jiangkuo has studied the influence of 1-methylcyclopropene pre-harvest bagging treatment on grape fresh-keeping effect, but the operation is cumbersome and difficult. promotion; in addition, there are studies on spraying flowers with 1-methylcyclopropene before harvest, but the biological characteristics of fruits, vegetables and flowers are different, the purpose of preservation is different, and the concentration of use is different, so there is no comparability
Fruits and vegetables are mostly harvested in high-temperature seasons, and the harvesting period is relatively concentrated, but the production area lacks pre-cooling equipment, and untimely harvesting often causes huge waste
In recent years, through the continuous development of 1-methylcyclopropene products, 1-methylcyclopropene preharvest spray-type preservatives have come out, but the relevant application research is still blank

Embodiment 1

[0028] Goji berries are sprayed with 1-methylcyclopropene (1-methylcyclopropene preservative: purified water = 5 grams: 1 kg) when they reach physiological maturity, and picked after 1 week to select non-damaged and disease-free wolfberries Put it into a micro-environment modified atmosphere fresh-keeping box (contains two small baskets with handles), pre-cool at 0~2 ℃ for 24 hours in the place of production, put 1 bag of 1-methylcyclopropene fresh-keeping bag, store it with a buckle cover, and then pass through The cold chain logistics vehicle (0-4 ℃) was transported to the cold storage (0-1 ℃) for storage, and the control was not sprayed with 1-methylcyclopropene before harvest, but only treated with slow release after harvest. figure 1 It is a comparison chart of whether 1-methylcyclopropene is sprayed before harvest or not when it is stored for 42 days. It can be seen from the figure that the wolfberry treated with 1-methylcyclopropene before harvest (rot rate is 0, softeni...

Embodiment 2

[0030] Blueberries are sprayed with 1-methylcyclopropene (1-methylcyclopropene preservative: purified water = 5 grams: 1 kg) when they reach physiological maturity, and picked after 2 weeks to select blueberries without damage and disease Put it into a micro-environment modified atmosphere fresh-keeping box (contains two small baskets with handles), pre-cool at 0-4 ℃ for 18 hours in the place of production, put 1 bag of 1-methylcyclopropene fresh-keeping bag, store it with the lid on, and then pass through The cold chain logistics vehicle (0~4 ℃) is transported to the cold storage (-0.8~-0.2 ℃) for storage. After storage for 40 days, the cold chain logistics vehicle was transported to the cold storage at the sales point at 0-4 ℃ (0-2 ℃), and then the air-conditioned box was opened, and the small basket containing blueberries was taken out, and packed in a degradable microporous antibacterial fresh-keeping bag , put it into a freezer (4-7 ℃) for sale, and use no degradable micr...

Embodiment 3

[0032] Fruits and vegetables are sprayed with 1-methylcyclopropene when they reach physiological maturity, harvested in a timely manner according to the needs of farmers, and put the undamaged and disease-free fruits and vegetables into the micro-environment controlled atmosphere fresh-keeping box (contains two small baskets with handles) ), after pre-cooling at the place of origin, put it into a 1-methylcyclopropene fresh-keeping bag, and store it with the lid closed. Storage mode: the cold chain logistics vehicle transported to the cold storage, opened the top cover to pre-cool and then buckled the cover for storage. The current conventional packaging of fruits and vegetables without pre-harvest 1-methylcyclopropene was used as a control.

Abstract

The present invention discloses a preservation method for picking, storage, transportation and sales of high-value fruits and vegetables. The method is as follows: when fruits and vegetables reach a physiological maturity period, a pre-picking spraying-type 1-methylcyclopropene preservation agent is sprayed on trees, timely picking or delayed picking is conducted, after sorting, the fruits and vegetables are put into a microenvironmental controlled atmosphere preservation box, after fully pre-cooled in an origin place, the fruits and vegetables are put in a physiological and disease-double-controlling 1-methylcyclopropene preservation bag, and cover locking and storing are conducted. Storage, transportation and sales links have the following three modes: (1) a fresh sales mode: the fruitsand vegetables are directly transported to consumers in a cold chain manner and the fresh sales mode is suitable for e-commerce; (2) a storage mode: the fruits and vegetables are transported to cold storages of a storage and sales place for storage in a whole cold chain manner and the storage mode is suitable for fruit and vegetable storage and sales enterprises; and (3) a sales model: the fruitsand vegetables are divided into full box sales and single basket sales and the sales model is suitable for different consumer groups. The treatment method can delay picking time of the fruits and vegetables, delays occurrence of senescence and decay of the fruits and vegetables, and increases commerciality and sales prices of the fruits and vegetables in the storage, transportation and sales links.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a preharvest spraying type 1-methylcyclopropene preservative that uses a micro-environment modified atmosphere fresh-keeping box (patent number 2015101651019) as a carrier to spray on trees during the physiological maturity stage of fruits and vegetables. A new cold-chain integrated fresh-keeping method for storage, transportation and sales of fresh-keeping and post-harvest physiological and disease dual-control type 1-methylcyclopropene physiological disease regulation. Background technique [0002] 1-Methylcyclopropene is a class of cyclopropene compounds. It is a new type of ethylene receptor inhibitor discovered in recent years. It can block the normal combination of ethylene and receptors in fruits and vegetables, and inhibit various physiological functions induced by ethylene. Biochemical reactions, thereby delaying the ...
