Important conditions for fresh flowers

Important conditions of fresh flowers preservation Fresh flowers correctness The use of excessive or insufficient quantity of preservatives will lead to poor results, and even have a negative impact on fresh cut flowers, so it should be strictly in accordance with the freshness of product instructions. Commercially-available fresh-keeping products are mostly professional scientific research enterprises that have been made into a product supply market after years of research and experiments, and generally have a stable effect of preservation. Different sources of water quality have dual effects on both sides of cut flowers; common water sources include: tap water, rainwater, well water, and ion-free water. Tap water is the most commonly used source of water and is easily available, but the quality of tap water in different regions, cities and even the same city is not the same. There is also a difference in the chemical composition, pH (pH), organic matter, and microbial contamination. For cut flowers, the low pH (4 to 5) is the most suitable, which promotes the water absorption of fresh cut flowers and inhibits the growth of microorganisms. The concentration of preservatives and the number of cut flowers, the size of the vase, and the material of the vase should be appropriate. Generally, a clean non-metallic vase with a volume of 1 liter of water is preferred. The dose of preservative should be accurate, and the leaves that may be soaked in the water should be removed to avoid damage to the stems, Cuticles or thorns, unless necessary, do not generally stab; cut flowers from 2 to 5 centimeters, when daffodils and other flowers are intermixed, do not cut the feet of daffodils; do not spray the head with water; this can cause gray mold; avoid Put the flowers on the dry, direct sun or heating side, away from fruits, vegetables, soot, such as bottle water left 1/3, should add fresh water. The height of the flowering containers is based on the softness and hardness of the wood material, softness, high hardness and shortness. The quality of the cut flower itself The quality of cut flowers directly affects the preservation effect. From the seedlings, the quality of the bulbs and the growth process of planting, such as the cut flowers themselves are inherently deficient (even if the cut flowers themselves are of good quality), plus no attention to post-harvest processing, or even wild packaging, resulting in dehydration, mechanical damage, bacterial invasion, The lack of nutrition, packing and transportation of respiratory heat, internal and external sources of ethylene and other serious injuries (this situation is very common in reality); even if there is no magic pill can not return! Flowers have their absolute life cycle, and after many damages such as harvesting, packaging, transportation, etc., are piled, rubbed, and squeezed, they are sold for a long time and the flowers are purchased by customers. The insertion time will be relatively short. The longer the time of transportation and sale, the shorter the vase insert time for flowers to the user's hands. If a customer purchases flowers in such a situation, then after using preservatives, the effect of fresh-keeping may not be obvious. This is not because the preservatives are not good, but the intrinsic quality of flowers is too bad. Of course, if the conditions are the same, Under certain circumstances, it is definitely better than clear water. Therefore, when fresh-keeping products are used for the first time, fresh-keeping bottles should be inserted in comparison with fresh water bottles, and the preservation effect will be seen after comparison.
