When will the roses be cut?

When will the roses be cut? Rose cutting can be carried out all year round, and the cutting effect is the best in autumn, which is easy to manage after wintering, and can bloom in the same year after planting pots in the second year. September to 10, the temperature of 20℃ to 25℃ is the best time for cutting Chinese rose, and its survival rate is as high as 95%.

Under normal circumstances, it is advisable to cut the horseshoe-shaped section, which is easy to take root. However, attention should be paid to maintaining air humidity, but at the same time, attention should be paid to drainage and ventilation. Cut with a sand bed, connect the atomizing nozzle and spray water every two hours. The top should be shaded by sugarcane. When cutting branches, soak rooting powder in water solution (100ppm), which is easy to take root and survive! Cutting is mainly divided into hard branch cutting and green branch cutting.

Hard branch cutting

Hard branch cutting is also called dormant branch cutting. Roses cultivated in the open field, from defoliation in autumn to germination in spring, are cutted 1 annual branch. Branches that are usually pruned in winter and have no pests and diseases, full xylem and full buds can be used as cuttings. Cutting length 10~ 12 cm, with 3~4 buds.

Make a high bed as a transplanting bed in a high dry place, which is both sheltered from the wind and sun. After the land is leveled, cover it with plastic film first, and then cut it to raise the soil temperature and promote rooting. The cuttings are inserted into the soil 1/2~2/3, and 1 buds are kept out of the soil surface, with an interval of 8~ 10 cm, and about 100~ 140 plants per square meter.

Green branch cutting

Green cuttings are also called soft cuttings. During the growth period of Chinese rose, the new shoots of Chinese rose are used for cutting. Generally, it is carried out in summer and autumn from June to 65438+10. When the top flower of the new shoot is damaged, the branches with full branches and spores under the flower are cut as cuttings. The cuttings are 10 cm long and have three buds. The upper bud is cut from the bud tip by 0.6~0.8 cm, and the lower bud is cut from the bud base by 0.2~0.3 cm. Insert the node of the transplanting bed and knock off the leaves.

Leave 1~2 buds 1~2 leaves on the ground, and cut off some leaflets as appropriate. Clean river sand or loose and breathable materials such as vermiculite, perlite and chaff ash are used as the matrix of the bed insertion. Spacing of cuttings is 4~5 cm, and 400~600 cuttings are inserted per square meter.

1, summer and autumn are a good time to cut rose shoots, and May and September are suitable for cutting in the open field. The best seasons for cutting roses at home are summer and winter. Summer 1 month or more is enough, and winter takes a long time.

2. The method of cutting at home is' soaking method', that is, soaking the branches of Chinese rose in water to make it sprout. Soak in clean water (tap water can only be used for a few hours), change the water every day, and the roots will grow in about 10 days. When the roots grow to 1-2 cm long, plant them in pot soil. It is best to use branches that have just blossomed, each with a length of about 20 cm, and cut off half of the leaves.

3. First of all, when selecting cuttings, because of inexperience or improper methods in the process of cutting roses, there is often a phenomenon of "false living". Therefore, branches with sprouting buds cannot be selected as cuttings. Especially when cutting with tender branches in the growing season, we should also pay attention to choosing branches with high maturity, full axillary buds and no germination as cuttings. If it is urgent to use the sprouting branches of axillary buds as cuttings, and the length is more than enough, the sprouting branches can be cut and reused. If it is a short branch, the sprouted axillary bud 1/3 can be cut off with a sharp knife or completely to inhibit its development and let the lower axillary bud sprout. This can promote it to take root and sprout in the future.

4. Secondly, in order to sprout leaves after the cuttings of Chinese rose take root, we should not only master the appropriate temperature and humidity, but also pay special attention to making the temperature of the medium in the cuttings seedbed higher than the air temperature by 1-2℃, so as to adjust the transfer of nutrients in the cuttings to the lower end and make the lower roots sprout leaves again.

Especially in autumn, it is a good time to cut rose shoots. At this time, it is very important to protect the mother leaves and prevent them from falling off when cutting the tender branches of roses in the growing season. Because the mother leaves are responsible for the formation of callus, adventitious roots and axillary buds sprouting leaves during the survival of cuttings. Therefore, it is more important to ensure that the mother leaves do not fall off, especially in autumn cuttings.

6, must cut the incision, reduce the wound area, oblique incision is the practice of cutting flowers (in order to increase the absorption of water). As for cutting before or after flowering, it is also random. If you remove the top, don't cut off the leaves, just put them in water and let them take root. Compared with cutting in soil, it has higher survival rate and faster rooting.

Generally, the time for transplanting rose seedlings is one month later, the root system grows well, the cultivated soil is planted well, and it should be watered in time after planting.

When do you cut roses in the north? Cutting and grafting are the main breeding methods. Rose cutting can generally be carried out in spring or early summer, early autumn, rainy season and late autumn.

In spring, cut off a strong branch with a length of 15cm in the middle, leave three leaves, insert them into the soil for two thirds, pay attention to shading and watering, and the cuttings can germinate after 3-4 weeks. When pruning in summer, the incision at the lower end should be below the node, which is beneficial to the wound healing and rooting of plants. Spraying water every morning will germinate in about 20 days. When cutting, if the lower end of cuttings can be soaked in 500~ 1000 mg/l indolebutyric acid or 500 mg/l indoleacetic acid for 1~3 seconds, the rooting of plants can be promoted.

When will Rosa multiflora 1 be cut? Cutting is carried out in April-May, 9-65438+1October, and the temperature is 2-5℃, so it is easy to take root and survive. In order to promote rooting, the incision can be dipped in 500 ~ 750 ml of indolebutyric acid powder for grinding, and the cuttings are selected from the robust flower branches of that year. After the flowers wither, remove the residual flowers and dead leaves under the flowers.

When is the best time for Chinese rose cutting to take root? It can be pruned by combining cutting of tender branches in spring and cutting of old branches in autumn and winter. In fact, you can get detailed information by searching for "cut rose" on the Internet. Here are a few words about cutting soil: it is best not to bring bacteria in the soil, which is easy to rot the cut wound; No fertilization; The soil is best to be breathable and moist, and media such as vermiculite and perlite can also be used (available online), and it should be properly moisturized and shaded in the early stage of cutting. ...

When are Chinese rose seedlings suitable for cutting? A: The best time for cutting is autumn, with young branches as cuttings, and the length is about 10 cm. Leaves and stems are removed from underground parts, and leaves and stems are removed from aboveground parts. After planting, water, you can see a little sunshine in the morning and evening, and then gradually increase the light time, and new roots can grow in a month or so. Don't fertilize before rooting, don't water too much, it's better to dry.

When will the cut roses be covered with plastic shed? The function of covering film is to increase temperature and keep moisture. It will be done in a few days. We need to keep an eye on the weather changes. There will be strong cold air crossing the border in the near future, bringing a new round of rain and snow. View original post >>

When is the best cutting time of Chinese rose?

Live buds: in April-May and September-65438+1October, when the temperature is 2-5℃, it is easy to take root and survive.

Hard branches: the fallen leaves of Chinese rose flowers can be cut until the next spring to germinate.

Tender bud cutting: Because the new buds grow vigorously in spring, the survival rate of cutting materials is high.

When is the best time to cut Chinese roses? How can the survival rate of cutting be high? Rose can be cut all year round, but summer and autumn are the best.

The simplest and quickest way to take root of Chinese rose is to take biennial branches of Chinese rose and cut them into three sections, with the top cut flat above the node bud and the bottom cut obliquely at about 0.5~ 1cm below the node. Leave 1~2 pairs of leaves at the top of the cuttings, cut off all the other leaves, and then insert them into pure sand without fertilization. Just pay attention to water saving and heat preservation, spray water on the leaves every two days, control the temperature at 15~25 degrees, and give light in a semi-shading way. If the leaves have not withered after 20 to 50 days, it means that they have taken root.
