Preservatives 1. Sugars include sucrose, fructose, glucose, etc. Concentrations range from 0.5% to 2%. Generally, the concentration of woody flowers or hard flower materials can be slightly higher, and the concentration of herbs or soft flower materials can be lower: When the flower is used, the concentration can be higher, so that the concentration of the delayed flowering period should be lower. In addition, the Chinese rose is more sensitive to sugar and its concentration should not be too high. It should be mixed with other preservatives. 2. Salt salt (NaCL), monosodium glutamate (mainly sodium glutamate), alum, etc. The concentration of salt and monosodium glutamate is generally about 0.1% to 1%, and the salt-tolerant flower concentration can be higher, and vice versa. The concentration of alum is generally around 0.01% to 0.05%. The role of the above substances is to supply the nutrient of flower materials and regulate the ion balance in the flower stalks. 3. The amount of vinegar is 1/10 to 1/2 of the amount of water. It is better to eat white vinegar and yellow vinegar in general more impurities, should be filtered when used. 4. Drugs generally include 3 tablets of aspirin, 2 tablets of vitamins, and 0.001% of penicillin in 1 liter of water. 5. Dishwashing essence Detergent has the function of activating water quality, sterilizing, dissolving pectin, forming a film on the leaf surface, keeping the degree of moistness of the leaf, preventing all pores from opening, and reducing the transpiration of water. The use concentration is generally 2% to 59%. Pre-insertion treatment 1. Immersion treatment If the squid has wilting before the bottle is inserted, the base of the squid can be cut off and immediately put into cold water. However, the flower head should be exposed to the water surface. After 1 to 2 hours, the flowers will be Can restore the original state. 2. Cut the water in the water and put it into the water. Use a pair of scissors to cut the desired cut-off area into a horse-like shape. If it is a woody flower material, the flower material can be cut longitudinally with a knife to enlarge the contact area between the flowering branch and water. 3. The end crushes some of the woody flower materials, such as clove, magnolia, crape myrtle, peony, etc., can be gently cracked at the base of the squid to 3cm, in order to expand the water absorption area and prolong the life of the flower arrangement. 4. Heat treatment method (1) Burning method The base of a woody flower or stalk rich in lotions and succulent flowers and plants is burned with a micro-fire (candle flame) to kill bacteria, and then the bottle is inserted. (2) The scalding method encloses the base of herbaceous flowers, such as hydrangea, dahlia, gladiolus, and cosmos, with paper, and then dipped in hot water at 70°C-80°C. After 2 to 3 minutes, remove the insert bottle. In this way, it can play a role in sterilization, elimination of air bubbles in the catheter, prevention of extravasation of the juice, and prolongation of flowering time. In addition. Can also be applied to the base of the squid, salt, vinegar, soaking, but also can play a role in preservation.
