Example Embodiment

[0032] Example 1:

[0033] Crystal grapes are sprayed with fungicides for disease prevention and control before bagging. 7. Harvest when they are ripe, dissipate the heat in the field, remove bagging, mechanical damage and pests and diseases, wax the fruit pedicles, and pack them in 3kg / bag Put them in a 0.02mm PE fresh-keeping bag, transfer them to a 1.5±0.5°C cold storage for 24 hours, and use ultraviolet light to sterilize the cold storage and crystal grapes during the pre-cooling period. The following treatments are carried out: CK: direct storage in bags is used as a control treatment; A: Add 1-MCP preservative at 1.0 μL / L and store in bags; B: Add 1 bag of CT-2 / kg and 1.0 μL / L 1-MCP and store in bags; C: Press 2 bags of CT-2 / kg 2 / kg and 1.0μL / L 1-MCP were put into bags and stored at low temperature.

[0034] Statistics of different treatment groups stored good fruit rate and seed drop rate, the results are shown in figure 1 .

Example Embodiment

[0035] Example 2:

[0036] Crystal grapes are sprayed with fungicides before bagging for disease prevention and control. Harvest when they are ripe, dissipate the heat in the field, remove bagging, mechanical injuries, and fruits that have been damaged by diseases and insect pests. Apply wax to the fruit pedicles and pack them in 3kg / bag Put it in a 0.04mm PE fresh-keeping bag, transfer it to a cold storage at 1.5±0.5°C for 24 hours, and use 10mg / m2 during the pre-cooling period 3 Ozone was used to sterilize cold storage and crystal grapes, and the following treatments were carried out: storage in bags without preservatives was used as a control treatment; 1 bag of CT-2 / kg and 1.0 μL / L 1-MCP was put in preservatives and stored in bags for the treatment group.

[0037] The good fruit rate and seed drop rate of different treatment groups during storage and shelf life were counted, and the results are shown in figure 2 .

[0038] From the above results, it can be seen that th...

Abstract

The invention belongs to the technical field of storage and preservation of agricultural products and particularly relates to a crystal grape storage and preservation method, comprising the steps of (1) spraying 1500-2000 times of Trichoderma agent, namely natamycin composite bacteriostatic agent one day before bagging, and picking when reaching 70-80% of maturity; (2) removing bags after picking, picking out rotten fruits, waxing pedicles, subpackaging PE preservation bag lined transfer boxes, healing at normal temperature in the shade for 12-24 h, placing the transfer boxes in a cold store, and sterilizing the cold store and fruits with ozone or ultraviolet; (3) precooling in the cold store at 1.0+/-0.5 DEG C for 24 h, adding a sterilizing agent and an ethylene blocking agent, tying the bags and storing. Severe biological disease damage, short shelf life, proneness to browning and other problems in existing crystal grape are solved, the shelf life of crystal grape is extended from 7 days to 60 days which leaves 6 days for the sales time, and the crystal grape storage and preservation method is simple to perform, high in efficiency and good in safety.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a storage and preservation method of crystal grapes. [0002] technical background [0003] The fruit of crystal grapes is round, yellow-green when fully mature, crystal clear and shiny, with tender flesh and unique qualities such as thick, juicy, and sweet. However, due to thin skin, easy separation of skin and flesh, and high sugar content, the skin is easily broken, browned, dried and browned, threshed, and microbial infection causes a large number of rots during harvesting and circulation, which severely limits the production of crystal grapes. Fresh sales time and sales range. [0004] At home and abroad, a large number of researches on the storage and preservation technology of other grape varieties have been carried out. The storage and preservation technology of bulk varieties of grapes is relatively mature. 2 It is t...
