How to keep roses for a long time

I believe we are all happy when we receive the roses. But how can roses be planted, and how can they be kept longer if they are the most received? The following editor will introduce the relevant knowledge to you.

First, how to plant roses

1. Temperature: like warm and warm, the optimum temperature for growth is 15-25, and the growth is poor or stops growing at a low temperature below 5 °C. Can withstand the cold, can endure the low temperature of-10 in winter, and the Yangtze River basin can survive the winter in the open field. Not very resistant to high temperature, when the temperature is above 38, the plant grows poorly or stops growing.

2. Light: like the sun, when the light is insufficient, the plant growth is thin, the flowering is few and the fragrance is light. At the height of summer, the strong sunlight around noon should be sheltered.

3. Watering: drought tolerance, but potted plants should keep the pot soil moist during the growth period in order to ensure the normal growth and flowering of the plants, and it is not easy to blossom when it is too dry. Not resistant to moisture, basin soil is too wet or stagnant water, easy to cause rotting roots of the plant. The amount of watering should be controlled before and after flowering; when overwintering deciduous leaves are dormant, there is less demand for water, and watering should be controlled to prevent the basin soil from getting too wet. However, in case of strong cold air attack, should be timely watering, keep the basin soil moist, can help to keep warm and anti-freezing.

4. Environmental humidity: when pregnant buds from April to May, water should be sprayed to the plant every evening to facilitate the expansion and opening of the buds.

5. Fertilization: like fertilizer, but it is not easy to bloom when it is too barren. During the growth period of potted plants, fertilizer should be applied once every 10 days, and nitrogen should be the main fertilization in the early stage; phosphate fertilizer should be increased during bud gestation, and nitrogen fertilizer should not be applied simply; fertilization should be stopped during flowering. The ground planting plants should apply sufficient base fertilizer after defoliation, and apply nitrogen fertilizer again in the early spring of the next year to promote new branches and make the branches grow strong.

6. Pruning: because the flowers bloom on the new branches that germinate in the same year, they should be pruned before sprouting. In addition to thinning and pruning the old and weak branches, withered branches and overdense branches, it is also necessary to strongly cut the remaining branches. Only 3-4 branches should be kept in each pot, and each one should be re-cut by 5-8 cm to promote the sprouting of sturdy new branches. In the growing period, except for proper pruning when the plant is too luxuriant, it is generally not pruned. The residual flowers should be picked in time during flowering, which is beneficial to the future flowering. I if you do not pick flowers, you can only blossom once a year. If you pick flowers, the plant can blossom many times. The sprouting ability is very strong, and the life span of the root can reach about 20 years, but the old plant does not blossom for more than 10 years, so it needs to be renewed once in 5 ~ 7 years.

7. Turn the basin: Hunxing turns the basin once every spring. Sandy loam, which is fertile and well drained, can also grow in slightly alkaline soil. The matrix can be prepared with materials such as garden soil, rotten leaf soil, coarse sand or perlite.

Pest control: there are powdery mildew, scab and shell insects, aphids, rose stem wasps, red spiders and other diseases and insect pests. When suffering from scab, the leaves appear yellowish disease spots, the back of the leaves have yellow powder, and gradually withered.

8. Common problems and their causes: thin branches, few flowers and weak fragrance are often caused by lack of light.

① lack of light; ② pot soil is too dry; ⑤ pot soil is too barren; ④ did not prune, did not pick the residual flowers after flowering; ⑤ did not turn the pot for a long time.

The disease spot appeared in the leaves and gradually withered to death was due to the disease.

9, ornamental and health care function: rose is a fragrant flower ornamental plant, which should be used as flower hedge, flower border and flower bed in garden. it can also be potted to decorate windowsill and courtyard.

The smell of roses can kill Mycobacterium tuberculosis, pneumococci, staphylococci, etc.; its fragrance can widen chest and promote blood circulation, prevent coronary heart disease, and make impatient mood mild, quiet, refreshing and happy; it also has a certain ability to absorb sulfur dioxide in the air.

Second, how to keep roses for a long time

1, the temperature of keeping roses should not be too low, just two or three degrees above zero, do not see the sun in a cool place.

2. It is best not to open the roses that have been planted in advance in the bucket with clean water, lest the flowers bloom early, and it is appropriate for the water not to exceed 8 to 10 centimeters. Change the water once a day and cut this branch every two days (ordinary scissors can be cut off obliquely). Remember to wear gloves, otherwise the hands will be stabbed in the eye, very painful. I tried it last year, and it's no problem to keep 2mi for 3 weeks with this method.

3. In addition, the petals are easy to have black edges after a long time, cut off or removed with scissors (if there are enough petals). When the leaves of roses and lilies turn black, the flowers and leaves are blown by the wind or cold air when you buy them. When buying flowers later, remember to wrap not only the flowers, but also the flowers and leaves, preferably with a newspaper.

4. Putting some vitamin C in the vase can prolong the life of flower arrangement.

Other tips for saving:

First, hot water method. Soak the base of the flower in boiling water for about 1 second, or soak it in hot water for two minutes, then soak it in cold water, which can infarct the incision and prevent the overflow of flower tissue juice. Mostly used in herbaceous flowers.

Second, the tea method. Rootless flowers inserted in a vase are easy to wither. In general, the flowering period of clear water is only three or four days before they gradually wither. If the cold tea is used instead of clear water, the withering time of flower arrangement can be delayed. If you use tea to arrange flowers, the flowers will not wither in seven days.

Third, beer law. Add a little beer to the bottle with flowers, or put the flowers into the beer bottle with foam, and then add the right amount of water, and you will find that the flowering period of these flowers is much longer. This is because beer contains ethanol, which disinfects and preservates incisions, contains sugar and other nutrients, and provides nutrients for branches and leaves.

Fourth, injection method. Often used in aquatic flowers. The flower base of aquatic flowers is very fragile, and once they leave the place where they naturally grow, the flowers are easy to wither, so water can be injected from the flower stem with a syringe to maintain the flower's life.

5. Pharmacy method. Adding an appropriate amount of fresh-keeping agent to the container of flower arrangement can prolong the florescence of flower arrangement. In addition, the addition of appropriate amount of boric acid, sulfur, salt, vitamins, salicylic acid and carbonic acid can prolong the flowering period. In addition, inserting calamus orchid with 1/3000 aspirin solution or 1/2000 potassium permanganate solution can prolong the flowering period by three to five days.

Sixth, the method of burning. Put the end of the flower branch on a candle flame and barbecue, soak it in alcohol for one minute, and then bleach it in clean water. It is often used in flowers with milk overflow in flower stems, such as poinsettia, peony, chrysanthemum and so on.

Seventh, the method of enlarging the cutting surface. The base of the flower branch is obliquely cut or cut into two to four parts and embedded in the pebbles to open the crack: or crack the base with a hammer to expand the water absorption. Mainly used in woody flowers, such as magnolia, hydrangea, cloves, wisteria, azaleas and so on.

When buying flowers in the future, you should remember to wrap not only the flowers, but also the flowers and leaves, preferably with a newspaper.
