Embodiment 1

[0019] A, in melon young fruit period (after flowering 2 weeks), fruit rapidly expands period (after flowering 3 weeks), network pattern formation period (after flowering 4 weeks) and four periods before adopting, all carry out spraying treatment, 1mmol / l The acetylsalicylic acid treatment solution is evenly sprayed on the surface of the fruit with a sprayer. When spraying, the nozzle is sprayed evenly in a circular shape at a distance of 5 cm from the surface of the melon fruit. The spraying amount is 40L / mu; the acetylsalicylic acid treatment solution is prepared by the following method: Stir the acetylsalicylic acid with ethanol to fully dissolve, and use 10ml of ethanol for each gram of acetylsalicylic acid.

[0020] B. Cleaning and disinfection

[0021] After the melon fruit is picked at the commercial maturity stage, select the healthy fruit with uniform size, no mechanical damage and disease, disinfect with 2% hypochlorous acid solution, rinse with clean water, and set...

Embodiment 2

[0025] A, in melon young fruit period (after flowering 2 weeks), fruit rapidly expands period (after flowering 3 weeks), network pattern formation period (after flowering 4 weeks) and four periods before adopting, all carry out spraying treatment, 1mmol / l Acetylsalicylic acid treatment solution was evenly sprayed on the surface of the fruit with a spraying machine. When spraying, the nozzle was sprayed evenly in a circular shape at a distance of 10cm from the surface of the melon fruit, and the spraying amount was 45L / mu. The acetylsalicylic acid treatment liquid is prepared by the following method: stir and fully dissolve the acetylsalicylic acid with ethanol, and use 5ml of ethanol for every gram of acetylsalicylic acid.

[0026] B. Cleaning and disinfection

Embodiment 3

[0031] A. Cleaning and disinfection

[0032] After the melon fruit is picked at the commercial maturity stage, select the healthy fruit with uniform size, no mechanical damage and disease, disinfect with 2% hypochlorous acid solution, rinse with clean water, and set aside;

[0033] B. Hot water immersion treatment

[0034] Soak the cleaned and sterilized muskmelon fruits of each treatment in hot water at 55°C for 3 minutes.

[0035] "Effect Test"

[0036] 1. Materials and reagents

[0037] Test material: The test melon "Agate" was collected from the open-air field of Shoucheng Township, Minqin County, Gansu Province.

[0038] Experimental drug: acetylsalicylic acid (ASA), Tianjin Guangfu Institute of Fine Chemicals.

[0039] 2. Preharvest treatment

[0040] In the four stages of muskmelon young fruit (2 weeks after flowering), rapid fruit expansion (3 weeks after flowering), net pattern formation (4 weeks after flowering) and 48 hours before harvest, all dissolved 1mm...

Abstract

The invention discloses a safe melon cold damage control method used for solving the problem that cold damage is serious during melon fruit cold storage, the safe melon cold damage control method includes the step of post-harvest treatment, and particularly includes the following steps: A, washing and disinfecting are carried out, wherein after melon fruits are harvested in a commercial mature period, and the health fruits which are uniform in size, free of mechanical damage and free of diseases are selected to be disinfected through a 2% hypochlorous acid solution and washed with clean water for preparation; B, hot-water soaking is carried out. Heat treatment is a simple physical method for garden stuff post-harvest treatment, the cold damage can be reduced, the storage pest and disease damage can be prevented and treated, the storage quality can be improved, and the storage period can be prolonged; in addition, the safe melon cold damage control method is non-toxic and harmless, the chemical treatment pollution is avoided, the edible garden stuff safety is improved, and therefore a post-harvest physiology group pays wide attention to the safe melon cold damage control method. By means of the safe melon cold damage control method, before-harvest ASA treatment and post-harvest heat treatment are combined to be applied to garden stuff preservation and freshness, and effects are obvious.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable disease control, and in particular relates to a technology for controlling post-harvest chilling damage of thick-skinned melons. Background technique [0002] Melon has a long history of cultivation in my country, and the current cultivation area and output both rank first in the world. Thick-skinned melon belongs to the Cucurbitaceae Melon genus. It is rich in nutrition, sweet and refreshing, and has a unique flavor. It is deeply loved by the public. The Hexi region of Gansu Province is one of the main producing areas of thick-skinned melons in my country. Due to its unique climatic conditions, the quality of the melons produced is quite good, and agate is one of the main varieties. However, although its quality is good, the production period coincides with the high temperature in summer, coupled with the lack of necessary cold chain and effective post-harvest treatment, the quality drops rapi...
