What are the best ways to store flowers

　　Many people have been confused as to why the flowers from the florist remain so bright and colourful as soon as they open the door each morning, when in fact the average florist will have their own cold storage to preserve the flowers. If the flowers are not preserved, it is easy to wither, the cost of the florist will naturally increase, resulting in losses is also amazing.

　　1.temperature-controlled storage and preservation

　　Flowers cold storage can be divided into simple storage and preservation, cold storage and preservation, control freezing point storage and preservation. Simple storage and preservation is the use of local natural conditions, to create flowers and greenery suitable temperature, humidity, flowers and greenery to achieve the purpose of preservation of freshness, the disadvantage is that the humidity is not easy to control; in addition, pay attention to ventilation.

　　Refrigeration preservation is in a good insulation efficiency of the library in the device frozen mechanical equipment, according to the requirements of different types of flowers and plants to control the temperature, humidity and ventilation in the library to achieve the purpose of flowers and plants to preserve freshness, it is the current flowers and plants is one of the main storage methods.

　　In recent years, cold storage technology continues to improve the development of cold storage installation, loading and unloading equipment, automated cold storage continues to introduce new, computer technology has also begun to penetrate into the automatic cold storage, control of freezing point storage of fresh flowers and greenery good appearance, colour and lustre, this method has been applied in a small part of the region, in the near future, control the freezing point of the storage and preservation of freshness of the method will be a large-scale promotion of the implementation.

　　2.gas-conditioned storage preservation

　　Ca air-conditioned storage preservation, MA air-conditioned storage preservation, plastic film account air-conditioned storage preservation, MAP preservation method. The so-called Ca gas-conditioning storage and preservation, is the use of mechanical equipment, artificial control of the gas in the cold storage, to achieve the purpose of flowers and greenery preservation of freshness, this method, if combined with the low-temperature, the effect is significantly better than the ordinary refrigeration; at present, our country’s gas-conditioning storage and preservation is in the development stage.

　　3.decompression storage preservation and high pressure preservation

　　Decompression storage preservation is placed in the flowers and greenery in a closed library room, with a vacuum pump to pump out most of the air, so that the internal pressure down to about 10KPa, resulting in a low-oxygen environment, ethylene and other gases such as partial pressure is also reduced accordingly, and in the storage period to maintain a constant low-pressure, temperature of 1-18℃, the relative humidity of more than 95%. This method can reduce the respiratory strength of the fruit, and thus can delay the maturation and aging of the fruit, prolong the shelf life, but the construction of large-scale decompression storage library investment is large, the country is in the experimental stage.

　　High-pressure preservation technology is the use of external high-pressure and its internal steam pressure difference, inhibit the enzyme activity of organisms, kill a variety of pathogenic bacteria microorganisms, prevent the water and nutrients to the outside world, slow down the rate of respiration and ripening speed, effectively extend the storage period. It is currently a more advanced storage technology, but due to the limitations of high-pressure equipment has not been applied to the production field.
