Bsp sterilization method: add alcohol, potassium permanganate, camphor, boric acid, citric acid, salt, alum, etc. Putting it in water can play a role in sterilization. Only when water does not rot can plants absorb water and keep fresh. Note: it must be prepared into solution before use, and it must not be directly put into water without dissolution. When using salt, be careful not to have too high a concentration.
Nutrition method: after the flowers are cut from the mother, they lose their source of nutrition. Nutrients such as sugar, beer, aspirin and vitamin C can be added.
Spray injection method: for many flowers with hollow stems, you can put the flower feet under the faucet to force irrigation.
Precautions:
1. Keep the water clean: change the water every day, and cut the roots and expose new stubble every day. Remove the excess leaves soaked in water.
2. Stay away from accelerant _ ethylene: Stay away from vegetables and fruits, because they will release a lot of ethylene, which will lead to the withering of flowers. At the same time, the fallen flowers and fruits will be cleaned up in time.
3. Fresh-keeping temperature: 5 degrees for common flowers and 10- 12 degrees for tropical flowers.
4. Location: Away from direct sunlight in summer and away from the air outlet in winter.
2. How to raise small roses is better?
How to raise potted roses? Roses are sunny, cold-resistant and drought-tolerant plants. If they are planted in wet places, they will grow very weakly and bloom less.
So roses must be planted in sunny, ventilated, humid and well-drained places. When planting, apply sufficient decomposed organic fertilizer, and after planting, pour enough water. In the future maintenance, 1 time should be applied in early spring, 1 time before and during flowering, and 1 time before winter. If the weather is dry in early spring, it should be fully watered to promote flower bud differentiation; Cultivate the soil when flowering to prolong the flowering time; Prune properly after autumn to promote the germination of new branches. In this way, plants can produce more, bigger and more fragrant flowers in the second year.
3. How to raise small roses indoors?
Hello: About the choice of soil: The germination rate of rose seeds is low, so the soil for general sowing needs to be loose, breathable and high in water-holding capacity.
The commonly used soil is a mixture of vermiculite, peat, water moss, perlite and snake sawdust. , conditional can be configured by yourself; Ordinary weak acid soil without conditions can also be used, but there must be no foreign objects (such as stones, broken bricks, glass, etc. ) in the soil. Step 1: Soak the rose seeds in warm water of about 40 degrees, cool and soak for 4-6 hours, and take out the seeds. Soaked seeds germinate easily.
Step 2: put the seeds into the soil (note: the soil needs to be loose, breathable and have good water retention capacity). Generally, 5~8 seeds can be planted in each container. After germination, leave a stronger one according to the growth status of the seedlings; Leave 1~3 seedlings between seedlings after germination as appropriate.
After sowing, the container should be covered with plastic wrap (plastic wrap can also be used for convenient bags), and several holes should be punched in the plastic wrap to breathe. Put the container in the sun and keep the temperature at about 20 degrees.
Most seeds can germinate after a week. After germination, the seedlings are strong and transplanted to the ground.
Roses not only like sunshine, but also like proper fertilizer. In early spring, if some fertilizer can be applied to the roots of flowers, the flowers will bloom more vigorously in the flower season. Finally, talk about pruning. It doesn't matter if you don't cut it Pruning is to make the flowers bloom stronger in the coming year.
Now it's time to prune, that is, before it snows, prune all the old branches, leave the roots and branches, and boldly prune all the long branches, so that new buds will appear on the branches next spring. The reason is very simple, that is, the old branches are not strong enough, the new branches are more vigorous, and the flowers will be more and stronger.
4. How to raise potted roses?
Before planting, decomposed organic fertilizer should be applied as base fertilizer;
(1) Time of basin loading. It should be done after defoliation in early winter or before germination in early spring.
② Fertilize and water. Roses like fat. During the growth period, it is necessary to topdressing organic liquid fertilizer with nitrogen as the main fertilizer 1~2 times. After potted, it should be applied with decomposed organic liquid fertilizer every 10 day 1 time. Avoid planting in low-lying areas to avoid water accumulation. Usually every two years 1 time, each tree can retain 5~6 branches.
(4) Trim neatly and flourish, and pay attention to:
① Selection of planting sites. It should be planted in a well-drained place, which can promote the vigorous growth of plants and seal the soil. In the early spring bud germination period and dry season, pay attention to watering in summer to prevent the soil from being too dry. It is required that the soil is loose and fertile, and attention should be paid to the division of plants to prolong the flowering period.
④ Pest control. See related contents of common diseases of roses.
In order to make the roses colorful, some liquid fertilizers containing phosphorus and potassium should be applied during the bud formation period. Water should be done according to the weather conditions, and water should be done every day in hot summer. When the soil in the basin is dry, water it.
③ ramets. Because roses have a strong temperament. When potted roses are planted before bud germination, it should be noted that liquid fertilizer mainly containing phosphorus and potassium fertilizer should be applied 1 time before flowering. After defoliation, ditch around the plant, apply rotten leaf fertilizer and irrigate. Because the dormant period needs pruning.
(2) Fertilize and water, and clear the residual flowers in time after flowering.
(3) Pruning usually depends on the wet and dry conditions of soil watering.

1. You should plant roses in pots at home, and pay attention to potted roses.
(1) Time of basin loading. It should be done after defoliation in early winter or before germination in early spring.
② Fertilize and water. Roses like fertilizer. After potted plants are served on the table, apply 1 decomposed organic liquid fertilizer once every 10 days, and also apply some liquid fertilizers containing phosphorus and potassium in the germination stage. Water should be done according to the weather conditions, and water should be done every day in hot summer. Usually, the soil in the basin will be watered when it is dry, and the residual flowers should be removed in time after flowering.
③ pruning. Because the dormancy period needs pruning, it can promote the vigorous growth of plants and prolong the flowering period.

6. How to cultivate lobular roses?
Cultivation method The fruit is wrapped in a receptacle, oblate, green at first, and orange-red at maturity.
Roses are easy to breed and cultivate. Breeding adopts sowing, dividing plants and stringing seedlings.
Sowing should be done in autumn, and seeds should be stored in sand. Sand storage treatment method: mix a small amount of soil with sand, moisten it with water, make it manually agglomerate, and granulate when it is dispersed.
Then wash the seeds and mix them into the sand. In sunny or semi-shady places, dig a ditch with an east-west width of 60 cm and a depth of 80 cm, and bury the sand mixed with seeds in it, leaving pores.
Dig it out in the early spring of the next year, and it is best to plant it after the seeds are broken. The ramet propagation can be carried out in spring and autumn, especially in autumn.
1~2-year-old seedlings are separated from old plants with some roots, so the wounds can be disinfected better and survive easily. Cutting, mostly in July ~ August.
Two-year-old robust branches with 1.5 ~ 20 cm length were selected as cuttings. Each cutting should have at least three leaf buds, the lower part should be cut into horseshoe shape and the upper part should be parallel. You can use pot insertion and border insertion.
After insertion, do a good job of shading and sun protection, sprinkle water frequently, and maintain a certain humidity and temperature. It takes about a month to take root and become a new plant, and it can be transplanted after one year.
Roses like light, sunshine, cold and drought, so they don't need special anti-freezing protection in northern winter. It can grow as long as it is not dry and watered.
The requirements for soil are not strict. Generally, fertile soil can grow vigorously, flourish and blossom well. Fertilize frequently in summer, 15~20 days, and water in time after fertilization to prevent seedlings from burning.
Prune in autumn to prevent overgrowth and affect flowering and plant appearance. There are many aphids in roses, so we should pay attention to prevention and control.
The cultivation of roses is not strict with soil, medium alkaline or slightly alkaline soil is the most suitable, and slightly acidic soil can also be used. Therefore, roses should be planted in fields with sunny ventilation and good irrigation and drainage conditions, and in fertile loam on the edge of the land.
Roses should avoid low-lying and waterlogged areas. When waterlogging occurs, the lower leaves turn yellow and fall off, and even the whole plant dies. The flower bud and germination of roses need an average temperature above 7 degrees, and the effective accumulated temperature from the initial stage of germination to the flowering stage needs 365 degrees, which generally depends on the temperature.
Dry hot wind and soil drought are the most taboo in the rose period. For fields with water conservancy conditions, irrigation can be carried out in the bud period. Roses stop growing twice in the process of production and development (generally called summer sleep in June-July; 1 1-65438+ February is called hibernation), at this time, the branches do not grow and the branches do not elongate.
The dormancy period in summer is the best pruning period for flower picking seedlings. When hibernating, base fertilizer and overwintering water can be applied to lay the foundation for stable and high yield of flower buds in the coming year. Disease control: The most important disease of roses is powdery mildew.
The disease spreads quickly and does great harm, and prevention is the main thing. In the early stage, the stems and leaves can be sprayed with Bordeaux mixture or stone sulfur mixture. After flowering, triadimefon (preferably water) can be sprayed on the leaves.
7. Matters needing attention in rose cultivation
disease control
1, rose stem and leaf bee, a stem borer, mainly harms the stems of roses, causing branches to wither and leading to plant death. When pruning plants in winter, check the pulp of root stubble and find holes. You can drop 1-2 drops of 80% dichlorvos EC and seal it with mud. When twigs are found to be infringed, they can be cut down and destroyed.
2. The moth in the rose harms the leaves with larvae and eats buds and flowers at the same time. It can be controlled by spraying 90% crystal trichlorfon 1000- 1500 times or 50% chlorpyrifos EC 1000 times.
3, red spider, harm the leaves before and after, causing the leaves to dry and fall off. At the beginning of the disease, 20% dicofol EC or 20% tetracycline wettable powder 800- 1000 times as much as 1500 times can be sprayed, but all of them should be sprayed on the leaves, every 1 5 days/kloc-0 times, generally.

So roses must be planted in sunny, ventilated, humid and well-drained places. When planting, apply sufficient decomposed organic fertilizer, and after planting, pour enough water.
In the future maintenance, 1 time should be applied in early spring, 1 time before and during flowering, and 1 time before winter. If the weather is dry in early spring, it should be fully watered to promote flower bud differentiation; Cultivate the soil when flowering to prolong the flowering time; Prune properly after autumn to promote the germination of new branches. In this way, plants can produce more, bigger and more fragrant flowers in the second year.
1, potted time. It should be done after defoliation in early winter or before germination in early spring.
2. Fertilize and water. Roses like fertilizer. After potted plants are served on the table, apply 1 decomposed organic liquid fertilizer once every 10 days, and also apply some liquid fertilizers containing phosphorus and potassium in the germination stage.
Water should be done according to the weather conditions, and water should be done every day in hot summer. Usually, the soil in the basin will be watered when it is dry, and the residual flowers should be removed in time after flowering. Step 3 trim.
Because the dormancy period needs pruning, it can promote the vigorous growth of plants and prolong the flowering period. 4. Pest control.
