Abstract

The invention discloses a method for refrigerating crown pears in a cold store, and relates to the technical field of agricultural production. The method comprises the following steps of: boxing and packing the fruits, filling the pre-cooled fruits in the cold store for storing, cooling the cold store to the temperature of 15 DEG C before the fruits are put into the cold store, closing a store door after the fruits are put into the cold store, starting refrigeration, temperature and humidity instrument switches, controlling the store temperature to drop 1 DEG C every two days, cooling the store for 1 DEG C every day after the temperature is dropped to 10 DEG C, keeping constant temperature after the temperature is dropped to 0-1 DEG C, and keeping the relative humidity in the cold store at 85 to 90 percent. By adopting a cold store fresh-keeping mode in the method, the storage and fresh-keeping time of the crown pears is long; cold damage of the crown pears can be effectively avoided by step-by-step cooling; the operation is simple and convenient; and the refrigerating conditions are easily controlled.

Description

The method of a kind of yellow hat worn by a Taoist priest pears warehouse-in refrigeration
Technical field:
The present invention relates to field of agricultural production technologies, relate in particular to the method for a kind of yellow hat worn by a Taoist priest pears warehouse-in refrigeration.
Background technology:
China is one of cradle, pear plant center, and the pears of Asia pear mostly come from east Asia, and Japan and Korea also are the original places of production of Asia pears; The white pear of domestic cultivation, Chinese pear, Ussurian pear all originate in China.
Dangshan pear is the famous product in the Chinese fruit.Characteristics such as it is with very large, the yellow bright beauty of fruit, and skin approaches succulence, and the meat multinuclear is little, and is sweet crisp are famous at home and abroad.Dangshan County was in Guiness Records China crisp pears first county, the selected world in 2010.
Because the Dangshan pear kind is single, quantity is big, the maturity period is consistent, on fruit selling market, various places, brings very big pressure.In order to promote the adjustment of the pears industrial structure, since two thousand, actively introduce China and foreign countries' pears kind, carry out high-grafting, make the selling pressure of Dangshan pear on the selling market, various places be able to alleviate.
In order to make the listing phase that prolongs pear; The storage technique of pear is vital; At present, mostly all be that to adopt underground ventilation to store sth. in a cellar fresh-keeping, the preservation and freshness time of this mode is short; Along with the introduction of China and foreign countries' pear new varieties, this traditional preservation and freshness mode can not satisfy the production needs.
Summary of the invention:
The object of the present invention is to provide the method for a kind of yellow hat worn by a Taoist priest pears warehouse-in refrigeration.
For realizing the object of the invention, technical scheme realizes through following mode:
The method of a kind of yellow hat worn by a Taoist priest pears warehouse-in refrigeration, the fruit loading packing is good, storage in the freezer of packing into after the precooling; It is characterized in that: with storehouse temperature drop to 15 ℃, fruit warehouse-in rear enclosed storehouse door starts refrigeration and humiture meter switch before the fruit warehouse-in; Control storehouse temperature was fallen 1 ℃ in per 2 days, drop to 10 ℃ after, fall 1 ℃ every day; Keep constant temperature after dropping to 0~1 ℃, the relative humidity in the freezer remains on 85~90%.
The method of said precooling is that the fruit after the vanning is In Shade, and placement 1~2 was put in storage before 8 o'clock next day round the clock.
When the relative humidity in the said freezer is high, adopt ventilation to reduce humidity, when relative humidity is hanged down, carry out the little mist humidification of high pressure through humidifier.
Utilize the method for ventilation to reduce the concentration of pernicious gases such as carbon dioxide and ethene in the freezer, also can be through placing the calcium hydroxide absorbing carbon dioxide, placement is adsorbed with the pernicious gases such as fragment of brick ethylene oxide of liquor potassic permanganate.
The invention has the beneficial effects as follows: this method adopts the fresh-keeping mode of freezer, and is long to the preservation and freshness time of yellow hat worn by a Taoist priest pears, and normal the damaging to plants caused by sudden drop in temperature of occurring of yellow hat worn by a Taoist priest pears can be effectively avoided in the substep cooling, and simple to operation, refrigerated condition is controlled easily.
The specific embodiment:
For the present invention is elaborated, further specify below in conjunction with specific embodiment,
The fruit loading packing is good, In Shade, place 1~2 round the clock, warehouse-in before 8 o'clock next day; The fruit case is put by Chinese character pin-shaped, and at a distance of 2~3cm, buttress pushes up at a distance of 60cm with wall, has stayed operation path between case and the case; With storehouse temperature drop to 15 ℃, fruit warehouse-in rear enclosed storehouse door starts refrigeration and humiture meter switch, controls the storehouse temperature and falls 1 ℃ in per 2 days before the fruit warehouse-in; After dropping to 10 ℃, fall 1 ℃ every day, keep constant temperature after dropping to 0~1 ℃, the relative humidity in the freezer remains on 85~90%; When relative humidity is high, adopt ventilation to reduce humidity, when relative humidity is hanged down, carry out the little mist humidification of high pressure through humidifier.
Utilize the method for ventilation to reduce the concentration of pernicious gases such as carbon dioxide and ethene in the freezer, also can be through placing the calcium hydroxide absorbing carbon dioxide, placement is adsorbed with the pernicious gases such as fragment of brick ethylene oxide of liquor potassic permanganate.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification is merely preference of the present invention, is not used for limiting the present invention, under the prerequisite that does not break away from spirit and scope of the invention; The present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
