Problems solved by technology

These two methods have the problems of short fresh-keeping time and high cost of mechanical input respectively.
Another method is to add preservatives, such as CIO2 treatment to keep the lily fresh; but the addition of preservatives has greatly affected the original quality of the lily and destroyed its natural medicinal and food value.
Another method is to use refrigeration, mainly in order to delay the loss of water to achieve the purpose of freshness preservation, but this method needs to slice the lily, which destroys the structure of the lily fruit, resulting in a short preservation period. However, if the lily fruit is simply refrigerated without slicing, its activity will not be destroyed because of the integrity of the lily fruit. At the same time, due to the structure of the lily fruit itself (the total number of leaves can reach hundreds of pieces) and a large number of piles during cold storage, the center temperature of some lily fruits will not be stable. It will not make it dormant, so this part of the lily fruit will germinate and further rot and mildew, and even infect other lily fruits with rot and mildew; and if the refrigeration temperature is greatly reduced, it will cause frostbite to the outer lily fruit; and if the fruit does not Stacking and directly spreading and refrigerating will greatly increase the cost
Simultaneously, above-mentioned method all has the problem of short fresh-keeping period

Embodiment 1

[0055] After digging out the mature lily, clean off the large pieces of soil attached to the fruit without washing, but it is necessary to keep the fine soil attached to the lily fruit, and finally use an elastic net with a length of 10cm and a diameter of 5cm Set it up.

[0056] Pack the lily fruit with the elastic net cover in a 20kg fruit box, and set a hard partition with 2cm ventilation holes between the fruit layers in the fruit box, and then put it into the cold storage. The carton is surrounded by holes with a diameter of 2cm The ventilation holes of the fruit boxes in the warehouse are 15cm between the left and the right, and the cartons are stacked up and down in 4 layers.

[0057] Lower the temperature of the cold storage from room temperature to -4 °C at a rate of 2.0 °C / min, then keep the temperature for 12 hours, then raise the temperature to 20 °C at a rate of 2.0 °C / min, and then keep the temperature for 12 hours; The temperature was lowered from room temperat...

Abstract

The invention provides a cold storage fresh-keeping method for lily bulbs. The method comprises the following steps: on the premise of not adding any preservative, placing fresh lily bulbs in a cold storage, cooling the lily bulbs from normal temperature to -10 to -2 DEG C, maintaining the low temperature for a period of time, adjusting the temperature to 12-28 DEG C, maintaining the temperature for a period of time, and repeatedly adjusting and circulating the temperature for a plurality of times so as to break the physiological activity of the fresh lily bulbs. The cold storage fresh-keepingmethod can not only keep the integrity of the lily bulbs, but also well destroy the activity of the lily bulbs. The method not only greatly prolongs the fresh-keeping period of the lily bulbs, but also can be implemented on a large scale without being limited by places, thereby improving the production efficiency and reducing the production cost. Besides, the method also has the characteristics of simple operation, low cost and easy popularization.

Description

technical field [0001] The invention relates to a method for storing lilies, in particular to a method for refrigerated and fresh-keeping of lilies, and belongs to the technical field of refrigerated and fresh-keeping of lilies. Background technique [0002] Lily, the scientific name (Lilium brownii var.viridulum Baker) is also known as Qiangshu, Fanjiu, Shandan, Daoxian, Chongmai, Zhongting, Moro, Zhongfeng, Zhongfenghua, Lily Garlic, Dafu Garlic, Suannao, Nocturnal lily, etc., are perennial herbaceous bulbous plants of the genus Lilium (scientific name: Lilium) of the Liliaceae family. They are native to China and are mainly distributed in temperate regions of the northern hemisphere such as eastern Asia, Europe, and North America. At least 120 species have been found in the world, of which 55 species are produced in China. In recent years, many new species have been produced through artificial hybridization, such as Asian lily, perfume lily, and fire lily. The bulbs are...
