What are the ways to store flowers?

　　Many people have been confused about why the flowers in the flower shop are still so bright when they open the door every morning. In fact, most flower shops have their own cold storage to store flowers. If the flowers are not kept fresh, they will easily wither, and the cost of the flower shop will naturally increase, and the losses caused are also amazing.

　　1.Temperature-controlled storage and preservation

　　Flower cold storage can be divided into simple storage and preservation, cold storage and preservation, and controlled freezing point storage and preservation. Simple storage and preservation is to use local natural conditions to create a suitable temperature and humidity for flowers and plants to achieve the purpose of keeping flowers and plants fresh. The disadvantage is that the humidity is not easy to control; in addition, attention should be paid to ventilation.

　　Refrigerated preservation is to install refrigeration machinery and equipment in a warehouse with good insulation performance, and control the temperature, humidity and ventilation in the warehouse according to the requirements of different types of flowers and plants to achieve the purpose of keeping flowers and plants fresh. It is one of the main storage methods for flowers and plants at present.

　　In recent years, refrigeration technology has been continuously improved and developed, and cold storage installation, loading and unloading equipment, and automated cold storage have been continuously innovated. Computer technology has also begun to penetrate into automatic cold storage. Flowers and plants that are stored and preserved by controlling the freezing point have good appearance and bright colors. This method has been applied in a few areas. In the near future, the method of controlling the freezing point storage and preservation will be promoted and implemented on a large scale.

　　2.Controlled atmosphere storage and preservation

　　Ca controlled atmosphere storage and preservation, MA controlled atmosphere storage and preservation, plastic film controlled atmosphere storage and preservation, MAP preservation method. The so-called Ca controlled atmosphere storage and preservation is to use mechanical equipment to artificially control the gas in the cold storage to achieve the purpose of preserving flowers and plants. If this method is combined with low temperature, the effect is significantly better than ordinary refrigeration; At present, my country’s controlled atmosphere storage and preservation is in the development stage.

　　3.Decompression storage and high-pressure preservation

　　Decompression storage and preservation is to place flowers and plants in a closed room, use a vacuum pump to extract most of the air, and reduce the internal pressure to about 10KPa, creating a low-oxygen environment. The partial pressure of gases such as ethylene is also reduced accordingly, and a constant low pressure is maintained during storage, the temperature is 1-18℃, and the relative humidity is above 95%. This method can reduce the respiration intensity of the fruit, thereby delaying the ripening and aging of the fruit and extending the shelf life, but the construction of large-scale decompression storage warehouses requires a large investment, and is currently in the experimental stage.

　　High-pressure preservation technology uses the difference between the applied external high pressure and its internal vapor pressure to inhibit the enzyme activity in the organism, kill various pathogenic bacteria and microorganisms, prevent moisture and nutrients from diffusing outward, slow down the respiration rate and ripening speed, and effectively extend the storage period. It is currently the most advanced storage technology, but it has not yet been applied to the production field due to the limitation of high-pressure equipment.
