The method of cutting Propagation of Flowers

Flower cuttage, also known as cuttings, is a common propagation method for cultivating flowers and plants. Cut off a part of the vegetative organs of the plant, insert it into the loose and moist soil or fine sand, and make use of its regeneration ability to make it root, branch and sprout and become a new plant. Because of its simple operation, high survival rate and no seasonal control, cutting propagation is widely used in flower propagation which is not easy to bear fruit and varieties are easy to mutate and degenerate. Cutting propagation plays an important role in flower cultivation. Most greenhouse herbaceous flowers and woody flowers are mainly propagated by cutting. Cuttage is a method to make use of the regeneration ability of plant vegetative organs, cut off a part of roots, stems and leaves, insert them into different rooting substrates (soil, sand, water, air), and make them take root and sprout and grow into new plants.

The method of cutting flowers into branches:

1. Softwood cutting. Also known as soft wood cuttings. Rhododendron, camellia, sweet-scented osmanthus, rose, jasmine, plum blossom, rose, Phyllostachys pubescens, cypress, cedar and other flowers and chrysanthemums, geraniums, dahlias, red flowers and other grass flowers, are often used this method. It is carried out when the new shoots or branches are semi-mature, and the time is mostly in summer and autumn. Generally, the length of cuttings is about 5 cm, with 2 leaves at the top, and the cut at the lower end of the cuttings should be cut under the node, which is easy to take root. Using pure sand or vermiculite as cutting substrate, the depth of cuttings inserted into the substrate is about 1 × 3 of the length of cuttings, spraying, watering and shading after cutting, and the suitable temperature is 20-25 ℃.

2. Hardwood cuttings. This method should be carried out during the dormant period of the plant. Before deciduous flowers and trees sprout after falling leaves, and evergreen flowers and trees stop growing until the sap flows in spring. Yingchun, hibiscus, hibiscus, crape myrtle, oleander, Michelia, mast and so on are suitable for reproduction by this method. In the north, after falling leaves in winter, the branches of the same year are cut to grow 20 to 30 centimeters in a section, bundled and buried in wet sand for the winter, and cut in the open field in the following spring. Cuttings can also be cut in combination with pruning before sprouting in spring. The cuttings should have at least 2-3 buds, the cut should be smooth, the upper end should be cut into a horizontal plane, and the lower end should be cut into a bevel. Management with softwood cuttings after cutting.

3. Single bud insertion. This method is to use one bud and one leaf for cutting, such as camellia, sweet-scented osmanthus, rubber trees and other flowers and trees, the cuttings are generally less than 10 centimeters, after cutting, special attention should be paid to water spraying, shading and wind prevention, so as not to lose water and affect survival. The experience is for reference only. If you need to solve specific problems (especially in legal, medical and other fields), you are advised to consult professionals in relevant fields in detail next.

How to cuttage and propagate flowers

Cutting propagation is to make use of the regeneration ability of plant roots, stems, leaves and buds to make it take root and sprout to form new plants under appropriate conditions. The advantages are: maintain the characteristics of each plant; bloom earlier than seed reproduction; breeding method is simple, convenient to obtain materials, high survival rate; when the conditions are available, all seasons can be carried out; species that can not bear fruit can be propagated by this method. The disadvantage is that the root system of the cutting plant is shallow and the growth period is short. Stem cuttings include hardwood cuttings and soft cuttings.

First, hardwood cutting: pomegranate, hibiscus, hibiscus, crape myrtle, spring, poinsettia and other deciduous flowers and trees often use this method. Before the sap flows in early spring. Select 1-year-old, 2-year-old strong and full branches, select the middle section, cut the branches into 10mur15cm long branches as cuttings, need to carry 2murs and 3 buds, and the top buds should be full and intact. The upper end is 0.5 cm above the bud, cut into a flat mouth, and the lower end is 0.5-1 cm under the bud, cut into an oblique mouth, and the bud is on the side of the tip of the oblique mouth, which is inserted into the cutting medium with a depth of 1 × 2 cuttings. Hardwood cuttings most tree species are buried in the ground before winter and replanted in spring. Some tropical and subtropical flowers and trees can also be cut in advance in the greenhouse.

Cutting Propagation of Rose

Second, soft wood cutting: greenhouse flowers such as inverted golden bell, geranium, begonia, open grass flowers such as a string of red, dahlia, beautiful cherry, evergreen broad-leaved flowers such as jasmine, rhododendron, Michelia, camellia, sweet-scented osmanthus, etc. From late May to September. Select the semi-lignified branches with leaves in the same year as cuttings, such as the semi-lignified branches at the lower end of the proximal tip after anthesis. The cuttings are about 6 Mel 10 cm long and should have 2 mi 3 buds. The cutting method is like a hard branch, and the lower leaves are cut off, while the upper leaves can be cut off as appropriate to reduce evaporation. The survival rate of cutting and inserting is the highest. When cutting poinsettia, geranium, oleander and other cuttings, a large amount of juice is often discharged from the incision, which must be inserted after the incision is dry, otherwise the incision is easy to rot and difficult to survive.

Third, leaf insertion: Begonia, chrysanthemum, stone lotus, tiger tail orchid and other species that can grow adventitious roots and buds at the vein or petiole, and can be propagated into new plants. When cutting a leaf with a petiole, keep the petiole about 3 cm, cut off part of the thin and tender leaf margin, and insert the petiole into the matrix; if there is no petiole, you can cut it with a knife at the intersection of the leaf vein and lay the leaf flat on the matrix to make it in close contact with the matrix, or fix the leaf vein in the matrix with a bamboo stick, which can root at the vein and grow into a new plant. Tiger tail orchid for fleshy sword-shaped leaves, can be transversely cut into about 5 cm leaf segments for cuttings, inserted directly in the sand, do not be upside down, new roots can occur at the base to form new plants.

Fourth, leaf bud insertion: rubber tree, eight immortal flowers, jasmine, mulberry and so on in the leaf insertion, although its petiole and leaf axil can take root, but can not sprout, therefore, can not grow into a new plant. Therefore, it is necessary to choose the leaf cuttage with an axillary bud at the base in order to develop into a new plant.

Fifth, root insertion: stick stem begonia, peony, Lingxiao, kiwifruit, hypericum, wax plum, persistent root Fu Lukao, lotus peony and so on. Flowers that can grow adventitious buds on their roots can be propagated by root cuttings. When the flowers and trees change pots, cut 5mur10cm root segments, insert them directly or obliquely into the soil, not upside down, and the upper end is flat with the soil surface, and then cultivate the soil properly after the new buds grow.

No matter what kind of cutting method is adopted, we must pour enough water after cutting, and then cover the cutting pot with glass or plastic film, in order to maintain a certain temperature and humidity, put it in the semi-shade, strengthen management, and then transplant and culture after rooting. In order to make the cuttage survival rate high, in addition to selecting good cuttings, the substrate is also very important, the substrate should not only have good drainage, but also have a certain degree of water retention. Vermiculite, perlite, slag and rice bran ash are better cutting substrates. The substrate should be kept above 20 ℃, that is, the atmospheric temperature should be above 25 ℃, so that the cuttings can be easily healed and rooted.

What are the flowers suitable for cutting propagation in spring? Cutting methods of Flowers

The Spring Festival is coming soon, which shows that spring is not far away from us. Spring is a good season for breeding flowers. Don't miss it! Here are 5 kinds of flowers that can be cut after the New year. When you wish relatives and friends a New year, you can bring back some branches.

Picture: longevity flower

1. Cutting methods of longevity flowers

1. Selection of cuttings: select a mature branch of 5cm from the exuberant longevity flowers as cuttings.

2. The cutting substrates generally choose plain sand, plain soil (loess without fertilizer), sawdust and so on.

3. Then insert the cuttings into the wet substrate. In order to make the longevity flowers take root faster, you can cover the flowerpot with a film, and the longevity flowers will take root in about half a month.

4. the longevity flowers cut in that year can blossom in the winter as long as they are managed properly.

Picture: hanging the Golden Bell upside down

Second, the cutting method of hanging Admiralty upside down

1. Cuttage selection: hanging upside down, the golden bell is 7cm long and the branches with pointed twigs are cuttings. It is best to leave 2 or 3 leaves at the top. Cut the cuttings and flatten them with a knife, and then remove 2 bottom leaves.

2. Cuttage treatment: the cuttings can be soaked in 0.1% potassium permanganate solution for half a minute, then the leaves are exposed, the base continues to soak in the solution for about 30 minutes, and then the cuttings are kept in clean water for 24 hours and 48 hours before use.

3. Cuttage method: insert the upside-down Admiralty cuttings into the substrate, then pour water thoroughly, and then place the cuttings in a bright place for maintenance. Spray water 2 times a day for 3 times a day to keep the substrate moist. Roots can grow in about 20 to 30 days.

Picture: Yushu

Third, the cutting method of Yushu

1. Selection of cuttings: choose more robust twigs or leaves.

2. Cuttage treatment: put the Yushu cuttings in a cool place to dry for 1 to 2 days before cutting. wait for the milk at the break to dry before use.

3, cutting method: the Yushu cuttings can be cut directly into the basin soil, and the basin soil should be kept moist after cutting. generally, about 20 to 30 will take root.

Picture: a string of red

Fourth, the cutting method of a string of red

1. Selection of cuttings: select a robust branch from the top of a string of red cuttings.

2, the cutting method is very simple, as long as it is soaked in water, it will not take long to grow roots, and then moved into the flowerpot.

3. Because a bunch of red seedlings in cuttings usually blossom on May Day after several daily management, such as heading, watering, fertilization, etc., after proper pruning, residual flowers are removed, cake fertilizer is applied 2 or 3 times a month, and blossoms for the second time since early July. In August, repeat the above method, and it can blossom again before and after National Day.

Picture: Carnation

Fifth, the cutting method of carnation

1. Selection of cuttings: you can choose 7 to 10cm lateral branches that grow between the axils of the middle leaves of the branches of the carnation, preferably with node marks to facilitate rooting.

2. Cuttage treatment: wet the cuttings with water before cutting, which is more conducive to its root growth.

3. Cutting methods: generally, the cutting medium is mixed with sandy soil or rice chaff ash, and the cuttings are directly inserted into the substrate. After cutting, attention should be paid to shading and moisturizing. Generally, it will take root and sprout in about 3 to 4 weeks.
