Embodiment 1

[0060] A structure for storing purple sweet potatoes in a shed includes a greenhouse, the width of which is 8 meters, and the length is 36 meters. There is a purple potato storage pit in the greenhouse, a drainage tank is provided at the bottom of the storage pit, a soil layer is provided on the base layer around the storage pit, an inner scaffold is arranged on the soil layer, and an inner shed film is fixed on the inner scaffold. The outer periphery of the storage pit is provided with drains, the drains are arranged along both sides of the length direction of the storage pit, and the drains communicate with the drains.

[0061] A kind of shed storage purple sweet potato method in the present embodiment, comprises the following steps:

[0062] a, select the greenhouse with greenhouse film 1 as purple sweet potato storage ground for use, the width of greenhouse is 8 meters, and length is 36 meters. Drains are excavated around the greenhouse, and thermal insulation film and ex...

Embodiment 2

[0075] The difference between this embodiment and embodiment 1 is: in step b, as image 3 As shown, the storage pit 2 is provided with a partition 9 every 3 meters along its length direction. The temperature in the greenhouse and the medium shed is adjusted to 14°C, the relative humidity of the air is adjusted to 90%, and the insulation film is PE shed film.

[0076] According to this method, the purple sweet potato is stored, and the rotten degree of the purple sweet potato is shown in Table 2:

[0079] Table 2

Embodiment 3

[0081] The difference between this example and Example 1 is that the purple sweet potatoes are classified into first, second and third grades according to their quality. In step b, as in image 3 As shown, the storage pit 2 is provided with a partition 9 every 3 meters along its length direction. In step d, the purple sweet potatoes are graded, and only one grade of purple sweet potatoes is placed in a separate space. The temperature in the greenhouse and the medium shed is adjusted to 12°C, the relative humidity of the air is adjusted to 85%, and the insulation film is EVA shed film.

[0082] According to this method, the purple sweet potato is stored, and the rotten degree of the purple sweet potato is shown in Table 3:

Abstract

The invention discloses a method for storing fruits and vegetables in a shed. The method comprises the following steps of: a, putting fruits and vegetables into a storage room, after a portion of the fruits and vegetables are placed, lengthways putting exhaust pipes into the storage room, stacking the fruits and vegetables around drain pipes until all the fruits and vegetables are placed; b, after finishing the placement of the fruits and vegetables, covering an overburden layer on the fruits and vegetables, and enabling the exhaust places of the exhaust pipes to be higher than the overburden layer; c, fixing an inner shed film on an inner shed frame where the opening of the storage room is; d, setting three temperature and humidity view points between an outer shed film and the inner shed film, setting three temperature and humidity view points inside the inner shed film, and setting a temperature and humidity view point on each exhaust pipe; e, fixing the outer shed film on an outer shed frame. The method for storing fruits and vegetables in the shed is suitable for storage of fruits and vegetables in large batches, and can efficiently guarantee storage quality of fruits and vegetables. Compared with a refrigerator mode, the method for storing fruits and vegetables in the shed is unnecessary to consume excessive electric energy and is lower in cost; compared with a common stacking and storing mode, the method for storing fruits and vegetables in the shed is steadier in storage environment and relatively good in storage effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural buildings or building groups. Background technique [0002] Postharvest losses of fruits and vegetables are quite alarming. According to the world's FAO estimates, fresh perishable fruits and vegetables, etc., reach 25-80%, which has exceeded the average limit level that developing countries can bear, making the insufficient food even more tense. The contradiction between population and food is more prominent. The commonly used methods of fruit and vegetable storage are refrigeration and stacking, but we know that cold storage requires renting a freezer, and the cost of using a freezer is relatively high, which will indirectly increase the cost of fruits and vegetables. Stacking is a simple and convenient method of stacking fruits and vegetables directly on the ground or in shallow ditch, or stacking them into round or strip-shaped piles (stacks) under the awning, and then covering them on ...
