Hydrangeas are very common in flower production. They are not only used as potted plants and garden plants, but more and more growers are paying attention to the cut flower technique of hydrangea, especially when exporting. However, the cut flowers of hydrangea are easy to wither, mainly because its leaves are too large, and even if it is supplemented with water, it is difficult to extend its insertion period. How to make the quality of the hydrangea cut flowers better and the flowering period is longer. Can take the following ways: 1 as much as possible to get rid of the leaves of hydrangea, 500 times the new high-fat film sprayed on the surface of the mosaic, put flowers and fertilizer evaporation. 2 Immediately after harvesting, spray the new high-fat membrane and soak the flower's stem into the water. Place the bucket containing water and nutrient solution next to the flower and put it with you. 3 It is best to harvest in the cool morning, and to harvest those plants that have half to two-thirds of the calyx soon to open. 4 Where the flowers are graded, they should be placed in an acidic environment with a pH of 4.0 to 5.0. Then at least 4 hours of rehydration is guaranteed. In the process of transportation, spray 500 times of new high-fat film on the flower surface to evaporate the water, and wrap the stem with water hose and water-filled cotton to continue to replenish the flowers. 5 Hydrangeas should not be stored in cold storage for more than 2 days. The appropriate storage temperature is 3 to 4°C or lower.
