Cutting flowers is a lively agricultural product with artistic temperament. From the time it is harvested and received into a commodity until it loses its use value, the whole process is shorter than that of fruits and vegetables, and it is prone to corruption. The post-harvest loss rate is about 20%, which is much higher than that of fruit and vegetable products. Therefore, the rational use of preservatives is very important. Flower preservatives can be used in all aspects of post-harvest treatment, such as from producers, wholesalers, retailers to consumers. Because the cut flower product is for the purpose of viewing, without causing environmental pollution, it can absorb preservatives through the stem base or other ways to regulate its physiological metabolism and delay the aging process. After many cut flowers and cut leaves are treated with preservatives, the shelf life can be extended by 2-3 times. The use of flower preservatives can also increase the number of flowers, maintain the leaf sign and the color of the petals, and thus improve the quality of flowers. The Netherlands attaches great importance to the study of floral preservatives. Every year, there are a large number of research papers and monographs on postharvest physiology and preservation techniques of flowers, which provide many useful information for flower producers, wholesalers, retailers and consumers. In developed countries, there are many professional flower fresh-keeping agent production companies. These companies have high quality products and good service. Flower producers and distributors can directly purchase various flower preservatives from professional companies. After many years of research, such as the famous Pokon-Chrysal company in the Netherlands, dozens of preservatives have been produced for different cut flowers. In all flower auction houses in Western Europe, it is explicitly required that the listed Liora flowers and carnation cut flowers be treated with silver thiosulphate (STS) in advance. Once the tested samples are not treated with STS, the entire batch of cut flowers will be expelled from the auction site. According to different uses, preservatives can be divided into three kinds of pre-liquid, pro-flowering solution and bottle inserting solution. Pre-disposal solution is used after cut flowers are cut and stored and transported before packaging to delay aging. Preservatives are generally used before retail sale to ensure that cut flowers harvested during budding are normally open. The bottle inserting solution is used by the consumer after the purchase of the cut flower, during the bottle insertion, to extend the life of the bottle insert.
