How to keep flowers fresh How to keep flowers fresh

First, the time should be early, and early morning is the best time to buy.

Second, it is advisable to choose those with full buds and slightly open.

3. Choose one with complete and straight blades.

Fourth, where there are water-soaked transparent patches on the branches and leaves, it means that the inventory has been refrigerated for a long time, and this kind of flower is not only easy to wither, but also the flower buds are not easy.

Fifth, touch the flower corner to see if there is a sticky feeling or yellowing, the more sticky or yellow parts are, the less fresh.

The cut flowers bought back need to be cut and repaired before they can be bottled. In addition, if there are too many impurities in the water or the secretion of the flower itself, rotten leaves and injured tissues after dethorning, it will cause bacterial proliferation and hinder the flower stem, so the treated flowers still need to be carefully cared for to maintain their beauty. The basic preservation steps are as follows:

1. Excision of flower corners There are two methods of excision, one is flat shear and the other is oblique cutting. Generally, the simple style is adopted, that is, the flower feet are cut off by 2 3 cm directly with flower scissors. The oblique cutting is to increase the water absorption area of the stem, and orchids need to be cut obliquely with the blade to avoid browning the wound.

Woody flowers can be cross-cut with the feet, or the ends can be broken with a hammer to absorb water.

2. Maintain the moisture of the duct Cut flowers are prone to loss of vitality, mainly because of the air running into the flower stems, or the bacterial decay caused by unclean water, which makes the flower stems absorb water poorly. To avoid air entering the incision, it is advisable to do this in water when cutting the flower stems. The incision of some flower stems will produce gelatinous material and blockage, at this time, the incision can be roasted with fire, or boiled in hot salt water for 1 2 minutes, and then taken out and soaked in cold water, which can inhibit the secretion of mucus, and has the effect of sterilization and promoting water absorption.

In addition, preservatives can be used. Preservatives have the effect of sterilizing and purifying water quality, which can prolong the life of flowers. If there is no preservative, a few drops of salt, vinegar or bleach can be used instead.

3. Remove the leaves Because the leaves soaked in water will cause microbial reproduction, resulting in the rot of the leaves and flower stalks, it is necessary to remove all the leaves under the water surface. If the cut flowers are placed in the bottle, the leaves of the bottle mouth part should not be too much, and can be removed moderately to facilitate air circulation.

4. Place in a ventilated place Flowers should be placed in a ventilated place where the sun does not shine to avoid accelerated withering due to the ethylene produced by themselves. In addition, keep away from the air conditioning vent and avoid direct fan blowing, otherwise it is easy to cause dehydration.

5. Remove wilted leaves and flowers Check the flowers and leaves for injury or wilting at any time, and remove them immediately once found, so as to avoid healthy flowers and leaves.

Sixth, change the water frequently The secretions of the flower itself and the decaying leaves or injured tissues are conducive to the growth of bacteria, resulting in the blockage of the flower stems and poor water absorption, it is best to change the water once every 2 3 days, especially in summer; It is best to trim off some of the flower feet at the same time as changing the water to maintain the water absorption. The flower stalk of the Asteraceae family is particularly easy to make the water spoiled and smelly, so it is advisable to change the water every day. When the weather is hot, you can put some ice cubes in the bottle to reduce the reproduction of bacteria in the water, and reduce the respiration rate of cut flowers, reducing the consumption of nutrients themselves.

If a preservative has been used, replace the water when the water is turbid and smelly. The more 3 to 5 days in summer, the more 5 to 10 days in winter, you can change the water once every 10 days.

First of all, fill the vase with nine-tenths of water, and then put in an appropriate amount of pure white sugar (if the vase is a large flower or a lot of flowers, it is also moderately increased, do not make the water too sweet) and then insert the flowers into the water, and put them in a dry, ventilated, and sunny place, which can prolong the flowering period and the flowers are colorful.

Don't add too much water, put it out in the sun.

Roses can last up to 15 days in the refrigerator!

There are ways to protect the freshness of flowers:1. Add sugar to insure flowers. You can supplement the nutrients needed by flowers, but to prevent the invasion of bacteria, it is best to add a little salt or vitamin C to avoid bacterial invasion.

2. Inject nutrient solution with a syringe to insure flowers. Water lilies, lotus, calla lilies and other flowers, you can use a syringe to directly inject sugar, salt and other prepared nutrient solutions from the flower stems.

3. With soda, you can insure flowers. The soda we drink in the summer, diluted two or three times, is a good nutritional preservation solution, which can be put into the roots of the flower to restore its freshness.

In-water shear method. Antiseptic. Salt coating method. Reduced transpiration. Scientific placement. Broken branch method. Burning method. Scalding. Add sugar to the water. Preservative mixture.

One end of the stalk of the cut flower is immersed in the pants jujube yard in the water, and the stalk can be cut to 2 3cm with scissors under the water, and the air content in the water is low, so that there is no air entering the void in the stalk after cutting, and no bubbles will be produced to hinder water absorption.

The water quality should be kept clean when raising cut flowers, and if the water quality is found to be turbid and smelly, it is necessary to change the water and clean the container. The soaking of the leaves of the cut flower rock is also the cause of water quality damage, so the appropriate amount of water should be left, and the area of contact between the stalk and the air should be left in the container to strengthen the gas exchange between the container and the outside of the container to prevent anaerobic bacteria from causing water quality changes.
