1, hot water method: put on the fire heating, burning to almost open, about 70 degrees water temperature, turn off the fire, the flower stem about 1 cm part of the water soaked for about 15 seconds, flowers away from the hot water, do not dip the heat into the petals, then in the hot water will be soaked in hot water stem part of the flowers cut off, pay attention to cut off a part of the more, about 2 centimeters or so, and then again the flowers in the vase on the The flowers can be kept fresh for a long time.

Principle: the stem of the flower has a conduit, the water can be sucked up and transported to the petals, in the arrangement of flowers in the conduit of the residual air encountered in the water, due to the air block, so that the water can not flow freely, will soon wither, but with this trick, the stems of the flower touched the hot water, the conduit of the air was driven out of the stems of the flower inside the water will be able to flow freely, mostly used for herbaceous flowers.

2, tea method: inserted in the vase of rootless flowers, easy to wither, the general water flower arrangements only three or four days of flowering gradually withered. If you use more Shen's herbal tea water instead of water, you can delay the wilting time of the flower arrangement. With tea water to flower arrangement, flowers in seven days will not wither.

3, beer method: in the bottle inserted with flowers into a little beer, or flowers inserted into a beer bottle with foam, and then add the right amount of water, the results will be found, the flowers of these flowers to extend the period of time much.

Principle: Beer contains ethanol, which sterilizes and antisepticizes the cuts, and sugar and other nutrients, and provides nutrients for the branches and leaves.

4, injection method: commonly used in aquatic flowers. Aquatic flowers flower base is very fragile, once you leave the natural growth of the place, the flowers are easy to wither, this time the syringe can be used to inject water from the flower stem in order to maintain the flower life.

5, pharmaceutical method: in the flower arrangement of the container to add an appropriate amount of flower preservative, can extend the flower arrangement of flowers. In addition, adding the right amount of boric acid, sulfur, salt, vitamins, salicylic acid, carbolic acid, etc. are to extend the role of flower arrangements.

In addition, with three thousandths of an aspirin solution or two thousandths of a potassium permanganate solution of iris, can extend the flowering period of three to five days.

6, the fire method: the end of the branch on the candle flame barbecue, into the alcohol immersion for one minute, and then into the water to bleach clear, commonly used in the flower stem in the milk overflow of flowers, such as a red, peony, chrysanthemums and so on.

7, the incision surface expansion method: the base of the branch cut diagonally or cut into two to four, embedded in small stones to support the crack: or hammer crack base to expand the surface of the suction. Mainly used for woody flowers, such as magnolia, hydrangea, lilac, wisteria, azalea, etc.

8, chemical method: chemical preservation that is, the use of preservatives to deal with, to inhibit the production of ethylene in flowers, reduce the intensity of respiration, to extend the life of cut flowers.

9, decompression storage preservation method: the principle of such methods to reduce the respiratory strength of flowers and flowers, thus delaying maturation and aging, to extend the shelf life.

First of all, the flowers and flowers in the airtight room, with a vacuum pump to pump out most of the air, so that the pressure drops to about 10kPa, to achieve a low-oxygen environment, ethylene and other gases such as partial pressure is also correspondingly reduced, and in the storage period to maintain a constant low-pressure relative humidity of more than 95%, the temperature is 1 to 18 ℃.
