How to extend the shelf life of flowers? How to extend the shelf life of flowers?

In order to extend the shelf life of flowers, we must first understand why flowers wither and wither so quickly after being picked. Because we pick the flowers and keep them in the water, it is easy for bacteria to grow in the water, and the bacteria are easy to enter through the incision of the flower branch, thus speeding up the withering of the flowers.

Therefore, if we want to extend the shelf life of flowers, we must start with bacteria all the time.

First of all, when we cut the flower branches, we should cut the incision into an inclined plane, and try to increase the area of the flower stem to absorb water, which can absorb more water. And cut a little bit every day to ensure that the incision can better absorb water.

Then, the excess leaves are cut off to reduce unnecessary water consumption and thus increase the water consumption of the flowers for storage. And the leaves must not be soaked in water, because the leaves are easy to rot, increasing the bacteria in the water, which is not good for the flowers.

You can put a little sugar in the water, which can provide nutrients for the flowers.

The water also needs to be added with a little bit of antibacterial growth, such as soapy water, aspirin, or potassium permanganate solution. Because after soaking in water for a long time, bacteria will be produced, and we add these to the water, which can inhibit bacteria and prevent bacteria from entering the flower branches.

Moreover, it is necessary to change the water every day, and when changing the water, the dirt on the vase and the dirt on the flower branches should be cleaned up to reduce the growth of bacteria.

If you find the above method troublesome, you can also come up with a lazy trick, that is, put the end of the flower branch on the fire and burn it, and then soak it in alcohol for 1 minute, so as to effectively prevent bacteria from entering the inside of the flower branch, so as to prolong the validity period of the flower. But it is not suitable for soaking in water anymore.

Every time many friends receive flowers, they hope that the flowers can be kept for a longer time, so that the joy of receiving flowers can also be maintained for a long time, and if the lover sends it, it can be immersed in love. In fact, there are methods and tips for extending the shelf life of flowers. <>

Tip 1: Flower preservative.

Some chemicals are added to the flower arrangement solution to inhibit the flower branches and prolong the freshness time.

How to make preservative: take a little dish soap and dissolve it in warm water, configure it into a 2%-4% solution, and insert the flowers into a volume containing a solution depth of 5cm, which can prolong the life of flowers by 2-3 times.

Trick 2: Beer.

You can add a little beer to the vase of flower arrangement, because beer contains ethanol, which can sterilize the incision, and contains sugar and other substances to supplement the nutrients of the flower branches.

Trick 3: Add salt water and sugar.

Adding a small amount of sugar in the water can prolong the opening time of the flowers, adding salt in the water has a certain inhibitory effect on bacteria, and the concentration of salt water and the concentration of flowers are different, which ensures the absorption capacity of flowers and maintains the freshness of flowers to a certain extent. However, the concentration of saline should not be too large, otherwise the cells will be dehydrated.

Tip four. The placement of flowers should be avoided from direct sunlight in summer and wind outlets in winter; Before arranging flowers, soak the flower branches in hot water to facilitate water absorption, sterilization and antiseptic, and blanch them in 80° water for 30s to increase the incision area and increase its absorption capacity.

Trick: Five carbonated soda with water.

In the case of Sprite, for example, Sprite is mixed with water in a 1:4 ratio and introduced into a vase, so that the flowers will still be beautiful after a week. The principle is that Sprite contains carbonic acid to kill bacteria, and high-sugar syrup can also be used as a raw material.

Hopefully, these tips will help you and give your flowers more time to bloom with their fragrance.

The preservation methods of flowers include scalding, refrigerator preservation, deep water first aid, use of preservatives, tea and so on.

1. Scalding methodImmerse the base of the flower branch in boiling water for about ten seconds to block the incision.

2. Refrigerator preservation methodWhen you go out, put the flower arrangement in a plastic bag and store it in the refrigerator.

3. Deep-water first aidWhen the flower hangs its head, cut off a small section of the end of the flower branch and put it in a container filled with cold water, leaving only the flower head, and after one to two hours, the flower branch will wake up.

4. Preservative methodAdd an appropriate amount of flower preservative to the container for flower arrangement.

5. Tea methodFor rootless flowers inserted in a vase, use freshly brewed tea, cool it instead of water, and use tea to arrange flowers.

How do you keep flowers fresh?

1. Scorching method. That is, the end of the flower branch is placed on a candle or match to scorch, and then soaked in alcohol for 1 minute, which can generally prolong the flowering period by about half a month.

Second, the method of crushing. That is, the end of the flower branch is broken by about 1 inch to expand the water absorption area to prolong the flowering period.

3. First aid method for immersion in water. If you notice that the flower head is drooping due to lack of moisture, you can cut off a section of the end of the flower branch, and then dip the flower branch into a container of cold water, so that the flower head is only exposed to the water, and after about an hour or two, the flower head will stand up.

Fourth, the method of pesticide preservation. Adding an appropriate amount of chemical preservative to the aqueous solution of flower arrangement can inhibit the withering of flower branches and prolong the opening time of flowers. If there is no preservative, it can be preservatived with a potassium permanganate solution of 1/4,000, or prepared into an aqueous solution of 1/3,000 of aspirin, which can also play a better role in preserving.

In addition, in order to keep the flowers for a long time, the indoor temperature should not be too high, to prevent oil smoke and dust from adhesing, to change the water regularly, and also to cut off the leaves of the flower branches inserted into the water, so as not to rot and pollute the bottle.

How to keep water flowers fresh?

The end of the flower branch is placed on the fire for 2-3 minutes until the end of the branch is brown and yellow, and then immersed in water. The fire burning method can prevent bacterial parasitism and promote the secretion of wetting fluid.

Tissue growth and healing have no effect on water absorption, resulting in more lush flowers.

The scalding method immerses the base of the flower branch in boiling water for about ten seconds, which plays the role of blocking the incision and preventing the sap in the flower branch tissue from overflowing.

When the deep-water first aid flower hangs its head, you can cut off a small section of the end of the flower branch, and then put it in a container filled with cold water, leaving only the flower head exposed on the water surface, after one to two hours, the flower branch will be so.

Wake up. This method is applicable to both herbaceous and woody flowers.

Use the preservative method.

Adding an appropriate amount of flower preservative to the container of flower arrangement can prolong the time of flower arrangement. In addition, with an aqueous solution of 1/3000 aspirin or 1/2000.

Potassium permanganate aqueous solution can prolong the flowering period for three to five days, and add an appropriate amount of boric acid, sulfur, carbolic acid, salicylic acid, salt, vitamins, etc., all of which are extended.

The role of flowering.

The enlarged incision method generally obliquely cuts the base of the flower branch; Or cut the base into two to four parts, embed small stone particles to support the crack; It can also hammer the crack base to expand the water absorption surface. where the oblique cutting method.

Most commonly used. The crushing method uses scissors handles to knock out the stem of the flattened root, and the water absorption area increases. Suitable for hydrangea, gentian, chrysanthemum, pearl flower, etc.

Chemical preservation method aspirin: It has the effect of killing bacteria and limiting the reproduction of microorganisms. All kinds of flowers are basically applicable, and the amount used is generally 1 3000. Salt: Apply salt to the incision and add it to water.
