Storage and preservation techniques of lily

(1) selection of storage-tolerant varieties China is the country of origin of lilies, and there are many types and varieties of cultivation. There are mainly varieties such as Longya lily, Sichuan lily and lily lily. Among them, the white, flat ball-shaped, tightly clasped, sweet Sichuan lily is of good quality and resistant to storage. Lily is generally harvested in early November, dig out the bulb with a spade, remove the stalk and soil in time, and cut off the fibrous root. Lily is not resistant to wind and sun, and newly dug bulbs should not be blown or insolated in the field to prevent outer scales from discoloration and dehydration. (2) the lilies after pre-cold fruit selection should be shipped to a cool place in time and spread evenly on the ground to dry, so as to dissipate the heat from the field so as to avoid the heat of the product. The drying time should not be too long to prevent the discoloration of scales. Stored lilies should choose bulbs that are white, fat, round, tightly clasped, without loose or scorched petals, and should be handled gently during operation to avoid injury. (3) Storage method ① yellow sand stratification first spread a thin layer of yellow sand or wet cheese on the floor in the room (library), and then pile up the selected lily bulb with a layer of yellow sand, which is about 1 meter high, and cover it with yellow sand to prevent lilies from being exposed to the air. When the lily is buried in the yellow sand, it can play the role of spontaneous air control, inhibit respiration, maintain a certain humidity, regulate dry humidity, and prevent the infection of pathogens. During storage, it is necessary to prevent heating in the pile and try to control the lower temperature, which can be stored until the following spring. ② cold storage can pack selected and pre-cooled lilies or pack plastic (11385, 55.00 and 0.65%) film bags and then box them, and send them to the cold storage for stacking or shelf storage. The storage temperature can be controlled at 0 ℃ and the relative humidity is 65% and 75%. It can often be stored until the following spring. The cold storage in California is to put the bulbs of Easter lilies in a polyethylene film box filled with dried peat at a temperature of-0.5 ℃ to prolong their storage life for several months. Plastic film can prevent water loss and inhibit its rooting, sprouting and disease development in peat and low temperature.
