The rose is about to wither, how can it come back to life 5

Rose is a set of greening, ornamental, health care, edible in one of the flowers, but also landscaping combined with agricultural production of good materials, suitable for mountain scenic spots combined with soil and water conservation a large number of planting, planting prospects. The main cultivation techniques are described below.

1. Growth habits and soil requirements.

Roses grow robustly, are very adaptable, hardy and early, and are not strict with the soil. Prefers sunny, cool, ventilated and well-drained areas, and grows best in fertile neutral or slightly acidic light loam soils. It is not tolerant to stagnant water, has strong tillering power, grows rapidly, the root system is mainly distributed between 15-50 cm, and the full flowering period is between April and May, after which it decreases significantly.

2. Reproduction and fixation.

1 Propagation There are many methods of propagation of roses, which are generally based on branching and cuttings. Dividing is carried out more often than spring and autumn, every 2-4 years, depending on the growth potential of the plant. Cuttings propagation, the south with hard branches, young branches can be, the former in March to select 2-year-old branches for mud cuttings, the latter in July and August to select the current year-old branches in the shed under the seedbed cuttings.

In the north, shoot cuttings are mostly carried out, carried out in a cold bed, and maintained in a high humidity state. In addition, it can also be propagated by grafting and embedding strips. The burying method is suitable for the arid areas of North China, and can be carried out from the fall of leaves to the germination of the following spring, and the earlier is better.

2 Planting Dividing method can be planted in spring and autumn, and seedlings propagated by cuttings and buried strips are better transplanted in autumn. The planting density is 2 m row spacing and the plant spacing is 1 5 m. When digging a pit, apply sufficient base fertilizer, and it is better to decompose organic fertilizer.

3. Field management.

In the north, after thawing in spring, combined with soil cultivation and after autumn leaf fall, decomposed organic fertilizer was applied once. and appropriate amount of nitrogen, phosphorus, potassium fertilizer or compound fertilizer. Irrigate frozen water once in early winter, and usually water in times of drought, especially in spring when the drought is severe. Rose pruning is simple and easy, just cut off the thin and whitish branches after flowering, and the overcrowded branches after the leaves fall in winter.

Fourth, pest control.

There are not many rose diseases and insect pests, mainly rust, borer, beetle, skin worm, aphid, etc., which can be controlled by high-efficiency, low-toxicity and low-residue safe pesticides before or after flowering.

5. Harvesting For different purposes of use, the harvesting time of roses is different. If the flower is used for medicinal purposes, it should be harvested when the buds are fully enlarged, but not yet open; Fresh cut flowers can be collected when the buds are just open; When eating, you can choose to eat between the buds are fully expanded and fully open, etc., and pay attention to the harvest time.

The above is cultivated in the open field, roses can also be planted in protected areas, and certain technical measures are taken, such as dwarf dense planting treatment, let it branch more, control the cultivation time, etc., which can significantly improve the yield of roses, and the long-term flowering period is continuous, and its economic benefits are more considerable.

Rose cultivation techniques.

If the rose withers can be revived by 1, blanching, 2, salt water or sugar water cultivation, 3, tea method, etc.

1. Hot perm

Many people don't know that you can prepare a pure cup of boiling water of 70 80 and add aspirin.

Or can be fresh, and then cut the roots of the flowers obliquely, increase the contact surface, when the roots of the flowers have many small bubbles in the water, the pole water absorption channel is opened, it is easier to absorb water and nutrients, 24 hours later, the flowers are rejuvenated, and then the scalded pole is cut off, replaced with fresh water.

2. Salt water or sugar water cultivation method

Add a little salt or sugar to the water in which the flowers are raised, or crush them at the incision of the flower branches, and rub them with salt to make the flowers bright and long-lasting. However, budding branches should not be soaked with salt water, otherwise it will be difficult for the flowers to bloom.

3. Tea method

Rootless flowers inserted in vases are easy to wither, so they are generally arranged with water.

The flowering period is only three or four days before it will gradually wither, you can cool the new tea that has just been brewed and replace the water, you can delay the withering time of the flower arrangement, the tea is a little stronger, the flowers will not wither within 7 days, and the flowers are bright and dazzling and fragrant.

What are the daily maintenance methods of roses?

Bonsai. The roses withered, it should be watered to replenish the water, but the withered flowers should be cut off in time. If it is a cut flower, you can add some powdered sugar to it, and you also have to cut off some leaves on the flower branches, as more leaves will increase the consumption of water, and the flowers will be easy to wither.

When buying cut flowers, you should choose the ones with buds to be put on, and you should buy the leaves are not wilting, the stems are thick, and the flowering period of roses is only 5 7 days, so you should choose the buds are firm, not soft, and the stems should be thick and straight, buy them home and cut the roots obliquely, and change the water every day.

Roses are sun-loving, cold-tolerant and drought-tolerant plants.

Its adaptability is strong, it grows poorly in shade and poorly ventilated places, roses are not selected for soil, but they grow best in deep and fertile, well-drained neutral or slightly acidic soils, but they are afraid of waterlogging, and the water accumulation time is slightly longer, and the lower leaves of the branches are easy to yellow, which seriously leads to death.

Roses should be reasonably pruned and pest control work, roses have strong growth, if not pruned in time, it is easy to lead to thin and weak branch growth, should be taken, thinning and pruning is the main, stubbing is supplemented, support new branches, and re-prune roses that have lost their flowering ability to grow weakly. Every half month, spray 1 time of powdery rust or chlorothalonil.

It has a good effect on preventing the spread of disease infection.

Roses can be remedied in time if they wilt, and for the withering caused by insufficient light, they need to be placed in a sunny place for normal maintenance; If it is caused by excessive watering and soil waterlogging, it is necessary to place the rose in a sunny, dry, ventilated and breathable place for maintenance; If it is caused by insufficient fertilizer, a rose plant should be watered once 50ml of 1000 times more water-soluble general fertilizer.

For the withering caused by insufficient light, it is necessary to loosen the soil for cultivating roses, put them in a sunny place for normal maintenance for a few days after watering, and do not remove the branches and leaves at will during maintenance, at this time the withered branches and leaves may still have vitality, and the maintenance of roses needs more than 8 hours of light every day.

Wilting of roses may be caused by overwatering and water accumulation in the soil. It is necessary to place the roses in a sunny, dry, ventilated and breathable place to speed up the evaporation of water. After the soil is restored to dryness, it is necessary to loosen the soil in time to prevent soil compaction from continuously damaging the rose plant.

If it is a lack of fertilizer caused by wilting, it is necessary to supplement fertilizer and nutrition in time, in the case of withering, water-soluble fertilizer is generally used to speed up the rapid absorption of nutrients by roses, and play a role in supplementing nutrition, a rose can be watered once 50ml of 1000 times more water-soluble general fertilizer.

The wilting of the rose may also be due to the black rot of the roots, which needs to be repotted, the plant is removed from the original pot, the residual soil on it is removed, the blackened and rotten root system is cut off, soaked in potassium permanganate for 30 minutes to disinfect and sterilize, and then carbendazim is applied to the wound and planted in new soil.

If you want to keep the roses from wilting, you can do the following:

1. Cut the cut edge of the rose branch into an oblique mouth with scissors, and then put it in a vase with half a bottle of water You can put some hydrogen peroxide in the water, so that the part that absorbs water is large and can absorb more water.

2. You can put a little beer in the vase, the beer contains ethanol, which can disinfect and preservatively cut the flower branches, and contains sugar and other nutrients, which can provide nutrients for the branches and leaves, and can also keep the roses fresh, and generally can maintain the flowers for 3 to 5 days without wilting;

3. Break a small piece of vitamin C, crush it, put it in water, or add a little sugar or add some potassium dihydrogen bicaphosphate to the water, and then cut a small section at the bottom of the received rose flower path and put it into the water with the "material". Spraying rose petals and leaves with a small watering can every day can can preserve the freshness of the roses.

4. Add an appropriate amount of chemical agent to the solution of inserting roses, if you can't buy a preservative for a while, you can use potassium permanganate 4/1000 aqueous solution to preservative, or use aspirin 1/3000 aqueous solution to make a simple preservative, which can prolong the preservation time of roses.

5. Soak the base of the rose in boiling water for about 10 seconds, or soak it in hot water for 2 minutes, and then soak it in cold water after taking it out, which can play a role in infarct incision and prevent the overflow of flower tissue juice.

6. The roses inserted in the vase are easy to wither, and the flowering period of the general water flower arrangement is only three or four days before it gradually withers. If you use tea instead of water, you can delay the time of flower arrangement, and the tea is better to be stronger, which can not only prolong the flowering period, but also the flowers are bright and dazzling and fragrant.

7. When the roses show signs of withering, cut off a small section of the end of the flower branch, and then put it in a container filled with cold water, leaving only the flower head exposed on the water surface, after 1-2 hours, the flower branch will wake up.

In addition to the above methods, the following points should be noted:

1. Do not soak the leaves of the flowers in water, so the leaves will rot, so be sure to remove the leaves soaked in water;

2. If you need to go out and not aggravate for a long time, you can take out the roses, put them in a plastic bag and store them in the refrigerator, which can be kept for several days.

3. Try to put roses on the dining table, bedside, and TV cabinet, and avoid putting roses next to heaters, air conditioners and balconies.

4. To change the water of the roses frequently, it is advisable to add half of the water in the container, and if there are conditions, it is best to change the water once a day. In summer, in order to keep the water temperature from rising, you can also put a few pieces of ice in the vase if the rose petals turn black or fester, and you should carefully pinch them off in time to prevent affecting other petals.

There are ways to extend its shelf life, but there is absolutely no way to keep it from wilting. Under natural conditions, flowers have roots that absorb water, inorganic salts, and some oxygen from the soil for what it needs. At the same time, some amino acids and hormones are synthesized in the roots.

When the branches are cut off, they lose the water and nutrients provided by the root system, and the branches will wither quickly. Therefore, to extend its shelf life, that is, to 'prescribe the right medicine' to extend the shelf life, the main methods are:

1. Apply flower preservative, such as adding 1000 grams of salt and sugar to 1000 grams of water, stirring well, and putting flowers in. However, metal containers should not be used, so as to avoid chemical reaction with the preservative and cause failure or even adverse consequences.

2. All the leaves of the flower branches that are immersed in water should be removed to avoid leaf decay and water spoilage;

3. Change the water every day in summer, change the water for 2 or 3 days in winter, and cut the lower end of the flower branch about 2 cm to update the incision by the way;

Fourth, the position should be placed to avoid direct sunlight, so as not to transpirate the water of the flower branches and accelerate the withering speed. But there should be enough light so that the flower branches can photosynthesize and produce some of their own nutrients.

Do not place fruit around the location. Ripe fruits release ethylene to promote the flowering and shedding process of flower branches.

First of all, when you raise roses, you can cut the branches inserted in the bottle to tilt a little, and then don't fill the bottle with water, you can put half a bottle of water, and you can also put some hydrogen peroxide in the water appropriately, you can observe it regularly every day, if the water in the bottle is reduced, you can properly carry out additives every day, that is, roses, take a break today, to ensure that the roses do not fall leaves and do not wither. Of course, if you don't want to put hydrogen peroxide in the bottle, you can also put some beer, because beer contains ethanol, which has a certain effect on disinfection, which can further ensure that the roses remain bright.

When I bought it, I added some vinegar to the bottle. Pruning the branches will do.

Environmental discomfort is the main reason, if you water it immediately after buying it, it will cause water to remain on the flowers, and the flowers will wilt; In addition, it is not recommended to change the potted plant immediately after the roses are bought.

Specific. <>

The newly bought potted rose may have wilted because it has not yet acclimatized, so keep it warm until it adapts to the new growing conditions. It may also be due to damage during transportation, at this time it is necessary to cut off its wilted flowers, and then carefully maintain them until they recover, or it may be that the root system of the plant itself has a problem, at this time, it is necessary to depot, cut off the rotten roots, and then replant it with transparent, fertile and loose potting soil.

1. Failure to adapt to the environment.

If the newly bought potted roses wilt, it is likely that the new maintenance environment is very different from the original flower market. It is an adverse reaction caused by the inability to adapt to changes in the environment in a short period of time.

The treatment is to keep it warm and provide it with some soft sunlight exposure, and after a while it will get used to it, and it will naturally recover.

2. Damage during transportation.

In the process of transporting it from the flower market to the new location, it is inevitable that there will be some small bumps, and if the bumps are too large and they are damaged, some of the flowers may wilt.

The treatment method is to cut off the wilted flowers on the plant, and then put it in a semi-shaded place, slowly maintain, and wait for it to recover.

Second, there is a problem with the root system.

If the root system of the purchased plant is weak, the flowers will wilt quickly, and the solution is to depot the plant and prune off all the roots that have rotted. Then plant it in a new potting soil with good permeability, maintain it slowly, and it can be restored after a while.
