Problems solved by technology

In 2006, my country's navel oranges were about 3.5 million tons, but the commercialization of navel oranges in my country was less than 30%, and the export of navel oranges was less than 1% of the output
[0003] However, in the large-scale storage methods of fruits in the prior art, harmful gases are often produced during the storage process, which causes the fruit pedicles to dry up and affects the storage quality of the fruits.

Embodiment 1

[0050] Embodiment 1. Conditional screening of the method of the present invention

[0051] 1. Screening of harvesting monitoring management technology

[0052] Fruit harvesting is an important link in operation and management, and it is the first hurdle in fruit storage, transportation and commercialization. The good environment of harvesting technology and transportation control directly affect the operating results. Improper harvesting and transportation will damage the quality of the fruit and cause the fruit to rot. Therefore, the picking batches that affect the quality of the fruit are studied, and combined with the production practice, the picking monitoring and management technology is summarized.

[0053] 1. Picking batch test

[0054] Different according to illumination, fruit coloring degree, in conjunction with factors such as artificial consideration, the present invention establishes two picking treatment experiments, see table 2 for details.

[0109] Embodiment 2. store navel orange with the inventive method

[0110] 1. Process technology route

[0111] Pre-harvest management→harvesting→primary selection→surface water removal (brush drying)→soaking in preservative solution→air drying→cooling and sweating pretreatment→wax spraying→air drying→information-based multi-factor sorting→single fruit bagging→miscellaneous wood Palletizing of boxed fruit units → storage in negative pressure forced exhaust ventilation and temperature control warehouse → delivery

[0112] 2. Process operation steps

[0113] 2.1 The newly purchased navel orange fruits are cleaned of diseased and insect fruits, deformed fruits, small fruits, etc., and stored in grades for later use.

[0114] 2.2 soaking fresh-keeping liquid

Abstract

The invention provides a navel orange storage and fresh-keeping method and a negative-pressure forced-ventilation type temperature-control storeroom storage method. The navel orange storage and fresh-keeping method adopts a negative-pressure forced-ventilation type temperature-control storeroom to store navel oranges. The negative-pressure forced-ventilation type temperature-control storeroom is characterized in that miscellaneous wood boxes are used to bed stored and are stacked to be in an ultrahigh # shape; a forced air inlet is arranged under the storeroom, a forced air outlet is arranged on the storeroom, and a temperature and humidity monitor and a CO2 monitor are also arranged in the storeroom. The temperature and air freshness are kept in the negative-pressure forced-ventilation type temperature-control storeroom, the harm of CO2 to the stored fruits is alleviated, the generation of harmful gases during storage is effectively controlled, and the method has energy-saving and environment-friendly effects and can be used for storing navel oranges and other fruits in a large scale.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a storage and fresh-keeping method for navel oranges, in particular to a storage and fresh-keeping method for navel oranges and a storage method in a negative-pressure strong-discharge ventilation and temperature-control storehouse. Background technique [0002] At present, the total output of oranges in the world is 110 million tons, of which about 60 million tons are consumed as fresh fruit, and 18 million tons of navel oranges are consumed. In 2006, my country's navel oranges were about 3.5 million tons, but the commercialization of navel oranges in my country was less than 30%, and the export of navel oranges accounted for less than 1% of the output. In recent years, with the support of the country's policy of vigorously developing the navel orange industry, the navel orange area and fruit output have grown rapidly. However, the navel orange market is a typical seasonal fresh food c...
