The difference between rose cuttings and roses

Roses and roses are so popular that many people don't know the difference in life. How to cut rose? The difference between and roses?

How to cut rose:

First, select branches. At the end of autumn and the coming of winter, when pruning the rose, remove healthy and sturdy branches, and they must not be new branches of the year, nor can they be old branches of three or four years old, that is, biennial branches, which are about 15 centimeters long. each branch must have three to four leaf buds, not all the big old leaves can be retained, but only one or two, so as not to affect the nutritional supply of branches, but also conducive to photosynthesis. Promote the formation of new roots.

Second, choose soil. The soil had better be sandy, not too sticky, it will affect the permeability of water and air, and it can not be all sand, so there is no nutrition. After the new branches are inserted, the soil must be kept moist for a week, but the soil should not be allowed to accumulate water, which can easily rot the roots and cause the branches to die.

Third, choose the season and weather of cuttings. Many traditional habits are spring cuttings, but after years of experiments, late autumn and early winter is the best season. The survival rate of branches planted in winter is 70%. When the branches are cut down in spring, the survival rate seems to be very high, but when the weather is hot in May and June, those new buds wilt before the new roots grow below, so they are usually planted at the end of autumn. After a winter of gestation, the new roots below have grown in spring. The above buds have the function of photosynthesis as soon as they come out, so the surviving rose can blossom in the same year. Choose cloudy and rainy days at the end of autumn, cut branches will be inserted into the soil 1/2, the winter sun is not strong, proper sun is also conducive to root growth.

Fourth, watering and fertilizing. Newly planted branches must be watered every day for the first three days, preferably shaded by big trees, or placed in a ventilated and shady place. Keep no more or less moisture, that is, do not accumulate water or become too dry, causing the branches to lose moisture. Fertilization is the most taboo of new cuttings, their absorption function is very weak, generally do not need to serve, if you really want to apply fertilizer, it is best to apply special fertilizer to promote root development.

The difference between rose and rose:

1. The appearance of rose and rose are roughly the same, but if you look closely, you will find that they are different. The stem of rose is low and short, the thorn is big, each node roughly has 3 or 4 hooks; the flower is large, the flower color is rich, the taste is light or tasteless, the leaflet is generally 3-5, the leaf is flat and smooth.

2. The stem of the rose is tall and long, with many thorns and most of them are straight thorns, the flowers are very small, the color of the flowers is very simple, and the flowering period is short. But the rose flower branch is very tall and straight, the flower color is rich, the taste is very fragrant, the rose leaflet is also 5-9, but the leaf is wrinkled under the leaf, the back of the leaf is white with small thorns, and the whole leaf is thicker.

Well, that's all for the difference between roses and roses, boys and girls.

Propagation method of Chinese rose cutting propagation method of Chinese rose in Daquan

Flower bonsai network guide: the common propagation methods of Chinese rose are cutting propagation, split propagation and strip propagation. Today, the Flower Bonsai Network will share an article on the breeding methods of rose flowers, and how to reproduce rose flowers. Let's take a look.

Rose is more adaptable. However, only by creating an environment suitable for its biological characteristics can its variety characteristics and the best ornamental effect be brought into full play.

Rose likes mild, hates hot, and avoids cold. The best temperature for rose to grow overnight is 20-25 degrees Celsius during the day and 12-15 degrees Celsius at night. When the temperature exceeds 30 degrees Celsius, the growth begins to be inhibited, the flower buds no longer differentiate, the differentiated flower buds and the formed flowers progress slowly, and the flowers are small. The color is not right and the flowers don't last long. During the period of flower bud differentiation, if you encounter a short-term low (about 5 degrees Celsius), it will produce twigs (that is, branches without flowers). There are great differences in the adaptability of rose to low temperature and cold among different variety groups. Some ancient rose could endure a low temperature of-20 degrees Celsius. Fenghua rose group and hybrid rattan group are generally able to withstand a low temperature of-15 degrees Celsius. Hybrid roses are not cold, but they can survive the winter safely without protection in a low-temperature rose at 10 degrees Celsius. Among the varieties in each variety group, there are also less cold-tolerant varieties.

The rose is resistant to drought and waterlogging. During the growing period, it is the peak growing season in spring, and the lack of water in the soil will affect the growth of new branches, flower size, flower color and flower life. The air humidity is too high, under the condition of poor ventilation, it is easy to be infected with diseases.

Rose likes plenty of light and can't stand shade. In the shaded environment, the plant has slender branches, thin leaves, light leaves and small flowers, but when flowering in strong sunlight, the petals change color and the life span is shortened.

Two methods of cutting and grafting are commonly used to propagate rose. Under certain conditions, other breeding methods are also used. For example, for varieties that are more difficult to root in cuttings, self-rooted seedlings are propagated by pressing, and some clump varieties are often propagated in separate plants; in order to cultivate a large number of rootstocks or cultivate new varieties, sowing is used to propagate.

Cuttage can be carried out all the year round, but it is suitable for stem cutting in winter or autumn, and attention should be paid to water management and temperature control in summer. Otherwise, it is not easy to take root, winter cutting is generally carried out in the greenhouse or greenhouse, such as open-field cutting should pay attention to increase moisturizing measures. It is used for sexual cross breeding in order to sow and breed. For a small number of famous species that are difficult to take root, they should be propagated by grafting, and the rootstock should be wild rose. Such as yellow series varieties.

Sowing and reproduction: the seeds of rose mature about 140 days after flowering and fertilization. After the dormant period (post-ripening), the seeds can germinate under suitable environmental conditions. Therefore, when the fleshy rose fruit changes from green to yellow to red (usually after the first ten days of October), take out the seeds (achenes). Do not dry, and then stratify with sea sand. The seeds will be sown in the early spring of the following year (March-April). The germination of thousands of dry seeds is seriously affected. In order to sow seeds early, but. In order to adopt artificial low temperature treatment to promote ripening and beating dormancy. The temperature of low temperature treatment is below 3 degrees Celsius, about 0 degrees Celsius, and the treatment temperature is 55-65 days. The treated seeds, sown at 20-25 degrees Celsius, began to germinate in 7 days and germinated one after another for about 1 month. Artificial hybrid seeds. When 7-13 true leaves appear, the top may form buds and blossom, which provides an early basis for the preliminary identification of the plant's Pushape, flower color, type, healthy flower and only one-to-two-season flowers in one year. Some seedlings do not form flowers, so they should be divided and transplanted as soon as possible.

Cutting propagation can be divided into two kinds: tender wood cutting and old wood cutting.

Shoots are inserted with semi-lignified branches, usually pruned branches after anthesis. After the flower fades, cut off the remaining flower with the following 1 leaf, and then cut off the following 3 leaves as cuttings. The cut at the base of the cutter is 0.3 cm below the leaf, which requires that the cut is smooth and the skin is not crushed. Cut off the bottom 1 leaf, leave 2 leaflets in the middle and 2 compound leaves at the top, cut off the rest, and then cut it.

Softwood cuttings are best rooted in late spring and early autumn. Although cuttings take root quickly in summer, cuttings are easy to be infected with bacteria and cause rot due to the prevalence of high-growth microorganisms, so summer cuttings should pay special attention to disinfection.

Cutting roots can be cultivated with vermiculite, pure sand or plain sandy soil. Vermiculite has good aeration and water holding capacity, and it is made by calcination. Therefore, it is relatively clean, and the rooting effect of cuttings is better. . Pure sand should sift out Taizu's sand grains, stones and impurities, rinse the powder and too fine sand with rinse water, and then rinse and disinfect them with boiling water. Plain sandy soil should be roasted by fire, or disinfected with chemicals before use.

The depth of cuttings inserted into roots should be slightly deeper in spring and autumn, about 1/2 of the total length of cuttings, and shallow in season, about 1/3. After fully boiling water after insertion,? Cover with glass or plastic film to moisturize and shade.

The main thing after cutting. The management job is watering. In the first 10 days after cutting, watering can be more frequent and keep a wet environment. After 10 days, watering can be controlled and dry again gradually. Water it, huh? Keep it slightly dry and moist. Cuttings take root at 20-25 degrees Celsius in 20-35 days. After giving birth, the cuttings should be transplanted, especially the cuttings in vermiculite and pure sand.

Old branch cuttings are carried out in the spring, generally using winter pruned branches, select strong, full axillary buds of annual branches, cut into 10-15 cm long branches as cuttings. The cut at the lower end of the cutter is 0.5 cm away from the petiole. The cut cuttings are bundled up and buried in the soil for the winter, with a depth of about 30 cm. The cuttings were taken out in the early spring of the following year (early March). Insert the bed and choose the sandy land. The cuttings leave only one bud at the end of the cutter to reveal the soil. Water after insertion. After sprouting, it is necessary to strengthen management, because although the terminal bud has not necessarily taken root, so the upper part of the soil is moist, and the leaves are often sprayed with water. When the leaves of the new plant do not wilt at noon, it shows that the base has taken root, from then on, we can spray less water and shorten the shading time, and combine watering with light fertilizer.

Transplant cuttings to survive seedlings, often die? In order to ensure transplanting survival, we should pay attention to the following points: first, the basin should not be large, the potted soil should not be too fat, second, transplanting into windless weather, carried out in the evening, third, with planting, do not expose the root system to the air for too long, fourth, seedlings should pay attention to take care of the root system, do not break, fifth, watering after planting should be watered thoroughly and placed in the shade to restore growth and remove shading.

Grafting propagation is faster than cutting propagation, and branch grafting is faster than bud grafting. In addition, Grafting can also be done by root grafting. The choice of breeding methods is mainly. Depends on the source of the rootstock and local customs.

Rootstocks are usually collected with multi-flowered rose and pink rose. these rootstocks have the advantages of easy reproduction, strong adaptability, developed roots, good affinity branch grafting and root grafting in early spring from February to March. When grafting, the rootstocks are dug out and carried out indoors, or they can be grafted directly in the field. Cut the rootstock 3 cm to 6 cm above ground, select the smooth side with xylem fir cut, about 2 cm long. Cut the robust branches with two buds as grafts, on one side of the scion, slightly longer than the cut (2.1 cm) of the wood incision, and at the base of the other side, obliquely cut about 0.5 cm into a bevel. Then insert the cut joint into the cut of the rootstock so that the cambium of the two sections are closely attached, and then tie it with binding material (hemp leather, plastic tape). If it is caught on the ground, then cultivate a mound with sand. When indoor grafting, the grafted seedlings can be buried in a warm place with semi-wet soil to promote healing, and then planted in the ground after 2 weeks or more.

Bud grafting in June to October: OK. Buds are often used to graft post-flowering branches, choose axillary buds with 5 small buds below the flowers. If the axillary buds are required to be full and have not yet germinated, cut off the branches, leave 2% to grow the petiole, cut off the leaves, wrap them with wet cloth or paper, and prevent them from drying. What if Yafu? Fully irrigate the rootstock 2-3 days before grafting. When grafting, first carve a "T" shape on the rootstock with a sharp knife, deep to the xylem, the upper horizontal line is 1.2 cm long, and the lower vertical line is 1.8 cm long. Pick out the "T" shape and prepare to insert the bud. When cutting the bud, first cut the knife at 0.5 cm above the bud, cut down slightly with xylem, cut to 1.8-2.0 cm, and pull off the skin. Then rip off all the wood from the bottom up and cut off the skin that is too long in the lower part. Pick out the "Ding"-shaped skin of the rootstock, insert the cut buds so that the ends of the buds are connected with the rootstock thread, and then tie the material. (hemp or plastic tape) tied from top to bottom. Then break the main tip of the rootstock to control its growth. In the following week, the leaf stalk fell off naturally and the bud was bright green, which proved that it had begun to heal in affinity. If the buds are enlarged after 2 weeks, all the bud holes on the rootstock will be removed to promote the grafting and germination. The buds grafted in October no longer promote the budding of the grafted buds to burn in the same year, so as to prevent the new branches from maturing before overwintering and suffer frost injury. Before sprouting in the following spring, cut off the rootstocks 0.8-1.0 centimeters above the grafted buds.

Grafting breeding technique of rose rose

Rose, rose and other grafting generally choose roses with developed roots, exuberant growth and strong disease resistance as rootstocks, and most of the selected varieties are pink roses and wild roses. rootstocks can be propagated by cuttings and sowed with useful seeds and grafted with seedlings. Grafting methods are usually bud grafting, branch grafting and root grafting, and most of them are bud grafting. The commonly used budding methods are T-shaped grafting and sticking budding.

one。 T-shaped grafting method

It is easy to peel off the phloem when the plant has more water content in the seedling growing season. When grafting, the scion selects full buds on the full new shoots of the same year, cuts off the leaves, retains the petiole, then takes a little xylem, and cuts a knife edge of 1.5 cm in length and 0.5 cm in width to form a T-shape. Then the bone part of the tail of the budding knife is used to pick out the incision so that the phloem is separated from the xylem. After gently ripping off the xylem of the grafting bud, it was inserted into the opening of the rootstock, so that the upper flat edge of the grafted bud was aligned with the cross-cutting edge of the rootstock, and the grafted bud was closely consistent with the cambium of the rootstock. Bind the wound with a plastic tape with a width of 0.6 cm to 0.8 cm and a length of about 20 cm to 25 cm to close the wound, exposing buds and petioles. After 5-7 days, the petiole was poked with your fingers, and the petiole was easy to fall off, that is, the grafting was successful, and it was unbound in time about 15 days after survival.

two。 Bud grafting method

It is a kind of single bud grafting when the cortex of rootstock is not easy to peel off in autumn and winter. The buds can be slightly xylem and cut into olive shape. The part of the rootstock is also cut into a similar section like budding. In the lower part of the incision, 2-3mm cross-cutting is left, and the residual pile is left a little to facilitate bud implantation. Align the bud with the cambium of the rootstock (the cortex is aligned with the naked eye) and bind it. This method is usually used to cut roses in Shanghai from September to October. Rooting cuttings are produced in November. After indoor grafting, they are planted in the seedbed at a distance of 10 to 15 centimeters. Plant 45 plants per square meter. The seedling bed should be covered with film or placed in the greenhouse, when the new seedling height is 30cm to 40cm, it can be planted.

Administration and Management

Rose transplantation is carried out between November and March of the following year, and pruning can be carried out at the same time, first cutting off dense branches and withered branches, and then cutting off old and weak branches, leaving 2 or 3 buds growing outward in order to spread out in all directions. Properly cut the especially strong branches to strengthen the growth of the weak branches. when the new branches grow too dense in summer, they should be thinned. After each batch of flowers, the upper part of the branches connected to the residual flowers should be cut off in time, so as not to make the seeds consume nutrients, and to retain the full branches in the middle and lower parts. promote early new branches to bloom again. Rose needs to re-apply basal flowers before flowering and then apply quick-acting nitrogen fertilizer to strengthen seedlings to promote flowering. Rose has strict requirements on water, not too wet and too dry, too dry and withered, and too wet will hurt roots and leaves.

The main pests of rose are aphids, leaf roll moth, diamondback moth and so on. 1000-1200 times dimethoate or isocarbophos are mainly used for control.

Factors affecting the survival of grafting

1. Selection of rootstocks:

2. Grafting affinity between rootstock and scion:

3. Cambium of rootstock and scion:

4. Temperature, moisture and oxygen conditions during grafting:

5. Quality of rootstock and scion:

Can rose flowers bloom in May cuttings in the same year? when is the flowering period of rose?

Rose is a flowering plant that many people like to raise in life, but many people don't know much about rose cuttage. Can rose cuttings blossom in May that year? When does the rose bloom? Let's take a look at it next.

Will rose flowers blossom in May cuttings that year?

Rose cuttings in May will not blossom in that year, but now cuttings can be counted as successful, but flowering is more difficult in that year, because it takes 1-2 months to take root after cuttage, and factors such as transplanting after cuttage survival will affect its flowering in that year. Under good planting management, it can not blossom normally until next year. At present, there is a kind of Japanese cinnamon can blossom in the same year after cutting in spring.

Two points should be paid attention to in cutting rose.

1. The seedlings of cuttings should not be too tender, and the branches that have been lignified should not be used, but the branches that are sturdy and dark green in color should be selected.

2. Circle the outer skin of about 0.2-0.3CM near the 1CM of the bud, and cut off the cuttage after a week. The survival rate is the highest. To ensure 100% survival, high-pressure reproduction can be used. In other words, it will definitely take root in the gap, but the disadvantage is that the high-pressure propagation method is only suitable for strong branches with a small number and slow speed, which is not as fast and simple as the cutting method, because the branches used for cutting can even be the remaining branches after pruning rose, which can reproduce dozens of seedlings at one time.

When is the florescence of Chinese rose?

The flowering period of rose is from May to November, and the flowering period is from May to June. If it has not been raised before, it can be raised before flowering, because the florists have changed the soil and treated pests in spring before, and they can watch the flowers soon after they are bought, which is helpful to improve the interest of enthusiasts in conservation.

The difference between rose and rose

Rose flowers and roses look roughly the same, but if you look closely, you will find that they are different. The stem of rose is low and short, the thorn is big, each node roughly has 3 or 4 hooks; the flower is large, the flower color is rich, the taste is light or tasteless, the leaflet is generally 3-5, the leaf is flat and smooth.

The stem of the rose is tall and long, with many thorns and most of them are straight thorns, the flowers are very small, the color of the flowers is very simple, and the flowering period is short. But the rose flower branch is very tall and straight, the flower color is rich, the taste is very fragrant, the rose leaflet is also 5-9, but the leaf is wrinkled under the leaf, the back of the leaf is white with small thorns, and the whole leaf is thicker.
