Tomorrow is Valentine's day. For the little sister in love, she will definitely receive a bunch of roses. How to raise fresh roses? How can roses last longer? Do you know how to raise roses to live longer?
How to raise fresh roses
1. Insert the vase in time. Cut the stem (45 degree angle section) to help the flower stem absorb water.
2. Keep the water quality of the vase clean, add a small amount of salt to prevent corrosion, and change the water every 1 day in summer and every 2 days in autumn and winter.
3. When changing water, cut short the flower branches properly, remove the leaves from the place where the water is soaked; clean up the fallen flower leaves in time, and spray water on the flower materials properly.
4. Location: keep away from fruits and vegetables / TV, keep away from direct sunlight in summer, and keep away from tuyeres in winter.
How can roses last longer?
Water cutting method
Cut the flower branches in the water so that the cut does not contact with the air when it is cut away from the mother body; or immerse the cut flower branches in the water and cut another section in the water to avoid the air entry. This method is applicable to all other flower branches except for the flower branches of the emulsion, but we must pay attention to the fact that the flower heads must be exposed to the water surface.
Heat treatment
It is divided into scalding and scalding. Soaking and scalding method is to cut the ends of flowers and plants, immerse them in 80 ℃ hot water for about 1 minute, then take them out and insert them into the bottle, which can block the incision, prevent the liquid in the tissues of flowers and plants from overflowing, thus prolonging the flowering period. Burn method is to burn the end of the woody flower branch on the flame for 2-3 minutes, cut off the burnt flower branch and soak it in alcohol for 1 minute, take it out, rinse it in water and then insert it into the bottle, which can not only avoid the blockage of the transport tissue of the flower branch, but also prevent the cut of the branch from being infected by bacteria. Keep the flowers hydrated. Hydrangea, clove, wood fragrance, peony, rose, chrysanthemum, ivory red, etc. can be treated by this method.
Physical treatment of incision
The first is to cut the cut into an inclined plane when cutting the flower branch to increase the water absorption of the flower branch; the second is to directly break some flower branches with brittle stems by hand to expand the cut so that the conduit of the flower branch will not be damaged; the third is to split the longitudinal plane of the cut into several parts and embed the small stone particles to open the cut; the fourth is to slightly twist the base of the cut flower branch about 3cm to increase the water absorption area and prolong the flower arrangement life, Generally, the plants and flowers should be cut obliquely, and the woody flowers should be broken by twists and twists.
Acid and alkali treatment
Apply acetic acid, dilute hydrochloric acid, boric acid, salt, etc. to the incision.
Increasing nutrition
Sugar, vitamin, growth hormone and medical painkiller can be added into the water of flower arrangement container, which can prolong the fresh-keeping time of flowers and also extend the flowering period, but it must be appropriate.
How to maintain fresh cut flowers? After the pretreatment of fresh cut flowers, we can start to arrange flowers. But we must pay attention to: the water quality in the container should be clean, the water depth should be above the incision, and the water surface and air should have the largest contact surface. The water depth of the plate type container should be the height of the flower inserted to ensure that the flower cut can absorb water in time; the water depth of the bottle type container should be at the widest part of the bottle body, because the water surface and the air contact surface are the largest, which is conducive to ventilation, the flower breathing is smooth, and the bacterial infection is reduced.
Reasonable water consumption
When arranging flowers, clean river water, well water and pond water shall be used. When the water is turbid, it shall be used after clarification. If tap water is used, it shall be put into the tank (barrel) for a day and night before use.
Changing water frequently
Change water every 1-2 days in summer and every 2-3 days in autumn and winter (in order to prevent the deterioration of bottle water, a small amount of salt and other preservatives can be put). When changing water, it is necessary to remove the remaining flowers and leaves, cut the flower branches properly, replace the cut, and spray water on the flower materials.
Reasonable arrangement of flower arrangement
Avoid direct sunlight in summer and stay away from heating or stove in winter. Otherwise, it will accelerate the respiration of flower branches and evaporation of water, which will easily cause flower wilting. In addition, it must be noted that flower arrangement cannot be placed near mature fruit, because the fruit will release ethylene, which is a harmful gas with special effect on cut flowers, and will cause early withering of cut flowers.
