Add a little sugar to the water and the flowers will stay fresh longer, right?

Right. After the flowers are picked, the original sugar can not meet the needs of flowering, so adding a small amount of sugar to the water can promote the opening of the buds and prolong the freshness period of the flowers. Before the flowers are picked, the water transport system inside the stem will send water from the root system continuously, and the whole pipe will be full of water, and after picking, the water will be temporarily deprived of water.

Especially at the base of the stem, air is constantly invading to form cavities, like embolism in blood vessels, and if this air is not expelled, the water cannot be transported upward. So trimming off the base two or three centimeters will allow the catheter to absorb water from the vase more freely.

Because the activities and growth of life need energy, for example, the human ingestion of sugar in the food is the same as the principle of providing energy for life activities, such as the starch contained in food is a kind of polysaccharide, such as sucrose, lactose in milk, fructose, starch digestion and transformation of maltose, etc., these sugars are converted into simple monosaccharide glucose after digestion, and the chemical reaction releases energy, which plays the most basic and important role in the continuation of life. Plants also need energy from sugars to grow.

Sugar is not a no-no.

But there are two other ways that can be effective.

The first one is to add the right amount of salt.

The second is the addition of vitamin C.

No! The sugar needed by the human body is then converted into energy, but this is not the case with plants!

You can put some beer in the water, which is said to keep it fresh.

I think I've heard that it's vitamin C!

1. White sugar: Putting white sugar in the water to raise flowers can keep them fresh and make them more vibrant. But be careful not to put too much, otherwise excess nutrients will lead to burning good roots.

2. Vitamin C: VC tablets can also be placed in the water of the poor skin limbs of flowers, which can prolong the flowering period, and promote the growth of flowers more vigorously, and the flower color is more colorful. 3. Iron nails:

Put an iron nail in the water to raise flowers, and the iron nail can decompose its own iron element in the water.

For example, the starch contained in food is a kind of polysaccharide, such as sucrose, lactose in milk, fructose, starch digestion and transformation of maltose, etc., these sugars are converted into simple monosaccharide glucose after digestion, and the chemical reaction releases energy, which plays the most basic and important role in the continuation of life. Plants also need energy from sugars to grow, for example, the photosynthesis of leaves is to produce starch under the action of chlorophyll, and the starch is converted into glucose for plant growth. Flowers are beautiful but leave the mother plant to cut off nutrients and water**, but also to wither quickly, cut flowers can be replenished in clean water, but the nutrients are only those contained in flowers, stems, and leaves, relying on the gradual consumption of nutrients in stems and leaves to maintain life.

Therefore, adding sugar to water can prolong the life of cut flowers, but the addition of sugar should also be done in moderation, otherwise it may be counterproductive. First of all, the added sugar is that flowers must be able to absorb and utilize, only monosaccharides and disaccharides with simple chemical structure can be absorbed and directly utilized, glucose belongs to monosaccharides, sucrose belongs to disaccharides, all sugars can be directly utilized and absorbed, and simple. Secondly, the concentration of sugar should be considered, different cut flowers have different nutritional needs, and the most suitable sugar content for common flowers known through research and practice is:

1-2% of roses on the market, 3-5% of chrysanthemums, carnations, lilies, asters, dahlias, peonies, peonies, plums, tulips, etc. Freesia 4-6%, gladiolus 5-10%.

Sugar is used as the nutrients of cut flowers, and also becomes the nutrients of microorganisms in the water, which promotes the reproduction of microorganisms, makes the water spoilt and sour, and accelerates the decay of the flower incision, but if some acidifiers or fungicides are added, the reproduction of microorganisms can be inhibited, so that sugar can prolong flowering.

In order to keep the flowers for a longer time, you need to supplement nutrients to prolong the flowering period, you can add a little beer, which can disinfect and sterilize the incision of the flower branches to prevent decay, and can also provide nutrients to prolong the role.

Aspirin aqueous solution can also be added to make a simple preservative. You can also add vitamin C, carbonated drinks, sugar, etc., and the effect is also good.

1. You can add two drops of dish soap to prevent decay.

2. Add a small amount of sugar to make the flowers bloom more beautifully.

3. You can put some "amoxicillin", which can inhibit the growth rate of flowers and prolong the life cycle.

4. Change the water once a day.

Salt in a vase can be used to protect it. Put sugar to increase nutrition. Putting 1 4000 potassium permanganate or appropriate boric acid, sulfur, carbolic acid, salicylic acid, vitamins, etc., in the vase has the effect of prolonging the flowering period.

Putting an aspirin in a vase has the miraculous effect of prolonging flowering. Because aspirin can cause the stomata of the leaves to close after absorbing water through the flower branches, it can slow down the evaporation of water.

Because sugar has the nutrients that flowers need, Sprite and Coke can also be used.

Sugar is a nutrient and energy, and a little more flower arrangement can prolong the flowering period.

,,, it seems that you can add some white vinegar for a reason.
