Propagation methods of Dragon Blood Tree

According to the propagation method of dragon blood tree, after it was introduced into China, the asexual propagation was mainly carried out by means of high pressure and cuttings in other areas, except that seeds were increased in a few tropical areas.

(1) striping propagation. The stem of the dragon blood tree grows mostly erect and has few branches. After several years of plant growth, the basal leaves fall off and naturally lose their ornamental value. According to this situation, breeders can propagate under high pressure in the high-temperature and humid season from May to July. The method is as follows: in the appropriate part of the stem of the plant, the ring is cut in a ring with a width of 1.8 cm to 2.2 cm, deep to the xylem, peel off the skin of the ring with a knife, wipe off the sap overflowing from the incision with a clean wet cloth, smear the upper layer of the incision with an aqueous solution of naphthalene acetic acid at 500 × 1000 ppm, then tie it to the lower end of the incision with a white plastic film, straighten it out into a funnel, and install the rooting stem mixed with moss and mountain soil. Wrap around the knife edge, pour through the water, fasten the top of the film, and then put the plant outside to cultivate, strengthen the fertilizer and water management. Dragon blood tree after high pressure, at any time to check whether the matrix is dry, to replenish water at any time. Generally, after 30-40 days of cultivation, new roots appear at the circumferential site, and can be cut off from the mother to grow into an independent plant from September to October.

(2) cutting propagation. Dragon blood tree can also be propagated asexually by cutting, the time is from May to June. At this time, it is the exuberant growth period of the dragon blood tree, the plant is rich in nutrition, and it is easy to survive after cutting. Before cutting, the mother plant with high ornamental value can be selected, and the robust branches that have been growing for more than two years can be taken. Each section is about 10 to 20 centimeters long, with or without leaves. The base of the cuttings is cut into a flat mouth, and the leaves are retained after the upper part is crosscut. The upper and lower incisions can be soaked in clean water to wash the overflowing sap, put it in a cool and ventilated place to dry for a period of time, and then soak the cuttings base 2-3 cm with 500-1000 ppm naphthalene acetic acid, usually 5 seconds, along with soaking.

Dragon blood tree cuttings, small pottery flowerpots can be used, and the matrix can be cut with vermiculite, perlite or plain sand sterilized at high temperature. One plant per pot, water permeable once after insertion, careful maintenance, the future management work is mainly to keep the matrix moist. Dragon blood tree wound healing quickly, take root early, sprouting quickly, generally 15-20 days, the incision under the action of wound hormone, will produce callus, 25-35 days later, cuttings under the action of endogenous hormones, can soon appear the primitive root, 35-40 days can sprout new roots, two months later, you can use the culture soil to turn over the pot transplanting, the above is the introduction of the propagation methods of dragon blood tree.

[FAQ] Propagation methods of Dragon Blood Tree

[expert answers]

1. Striping propagation

The stem of the dragon blood tree grows mostly erect and has few branches. After several years of plant growth, the basal leaves fall off and naturally lose their ornamental value. According to this situation, breeders can propagate under high pressure during the high-temperature and humid season from May to July. The method is as follows: make a circular cut at the appropriate part of the stem of the plant, the width of the ring is 1.8cm to 2.2cm, reach to the xylem, peel off the skin of the ring with a knife, wipe off the overflowing juice of the incision with a clean wet cloth, smear the upper layer of the incision with 5000-1000ppm aqueous solution of naphthalene acetic acid, tie it to the lower end of the incision with white plastic film, straighten it out into a funnel, and install the rooting stem mixed with moss and mountain soil. Wrap around the knife edge, pour once through water, fasten the upper end of the river film, and then put the plant outside to cultivate, strengthen fertilizer and water management. Dragon blood tree after high pressure, at any time to check whether the matrix is dry, to replenish water at any time. Generally, after 30 to 40 days of cultivation, new roots appear at the circumferential site, and can be cut off from the mother to grow into an independent plant from September to October.

2. Cutting propagation

The dragon blood tree can also be propagated asexually by cutting, which is from May to June. At this time, it is the exuberant growth period of the dragon blood tree, the plant is rich in nutrition, and it is easy to survive after cutting. Before cutting, you can select the mother plant with high ornamental value, and take the robust branches that have grown for more than two years, each section is about 10-20 cm long, with leaves or no leaves. The base of the cuttings is cut into a flat mouth, and the leaves are retained after the upper part is crosscut. The upper and lower incisions can be soaked in clean water to wash the overflowing juice, put it in a cool and ventilated place to dry for a period of time, and then soak the cuttings base 2-3 cm with 500-1000ppm naphthalene acetic acid, usually for 5 seconds. Dragon blood tree cuttings, nursery bed can use small pottery flowerpots, matrix can be vermiculite, perlite or high-temperature sterilized plain sand, on the pot for cutting. One plant in each pot, pour water once after it is inserted, put the seedling bed in the bright place of flowers, and maintain it carefully. The future management work is mainly to keep the matrix moist. The dragon blood tree wound heals quickly, takes root early, sprouts quickly, generally 15 to 20 days, the incision produces callus under the action of wound hormone, 25 to 35 days, cuttings under the action of endogenous hormones, the primitive body of the root can appear quickly, and the new root can germinate in 35 to 40 days. After two months, the culture soil can be used to turn over the pot and transplant.

3. Sowing and reproduction

Sowing and propagation need to collect seeds on old plants and sow seeds in spring. Sowing seedlings takes many years to grow up. The horticultural varieties of dragon blood trees usually do not need to sow and propagate, and the characters of the plants propagated by sowing are similar or different from those of wild species, thus losing the excellent characteristics of horticultural varieties. After the introduction of dragon blood tree into China, except for the seeds cultivated in a few tropical areas, asexual propagation was mainly carried out by means of high temperature, cuttage and tissue culture in other areas.

[editor's comments] there are three propagation methods of dragon blood tree, such as sowing, striping and cutting. after being introduced into our country, due to climate and variety reasons, it is generally not sowing, but mainly by pressing and cutting propagation. The above is the introduction of "the breeding method of Dragon Blood Tree" summarized and sorted out for you by the first Agricultural Classic editor. I hope this article will be helpful to you.

How to reproduce the dragon blood tree, the propagation method / pressing or cutting of the dragon blood tree

The dragon blood tree is a perennial plant, but after it has been planted for several years, the basal leaves may fall, resulting in a decline in ornamental value. At this time, flower friends should reproduce it, but some flower friends do not know its reproduction skills, so how does the dragon blood tree reproduce? Let's take a look at the breeding methods of the dragon blood tree.

How do dragon blood trees reproduce?

According to the planting experience of flower friends, the common propagation methods of dragon blood tree are cutting and striping, of which cutting is the most common, of course, flower friends can choose the appropriate way according to the actual situation, let's introduce the specific operation steps of these two methods in detail.

Propagation methods of Dragon Blood Tree

First, how to cut the dragon blood tree

1. Time

Generally, it should be selected in the most vigorous period of dragon blood tree growth, that is, from May to June every year, when the plant growth is more robust, the branches and leaves are more nutritious, and it is easier to survive after cutting.

2. Cutting steps

⑴ cuttings selection. Choose strong branches on the plant, preferably those that are more than two years old. Cut off the branches and divide them into 10-20 cm long segments, with or without leaves, but it is best to bring leaves.

⑵ cuttings treatment. Cut the base into a flat mouth with a tool, cross-cut the upper part but recently retain the leaves, then wash the juice of the cut with clean water and place it in a cool place to dry naturally, then soak the 2-3 cm area of the base with 500-1000ppm naphthalene acetic acid for 5 seconds and start cutting.

⑶ cuttage skills. After the cuttings are made, you can start cutting. how does the dragon blood tree reproduce at this time? Insert the cuttings into a flowerpot with a matrix, which is made of vermiculite and perlite, preferably sterilized, then watered through, and then managed in a cool place.

⑷ maintenance and management. Generally, no watering is needed in the process of rooting, but it is necessary to keep the substrate moist, which allows the scissors to heal quickly and begin to take root, while it usually takes 35-40 days from cuttage to rooting. Do not rush to transplant after rooting, you can wait 2-3 weeks to transplant to other places depending on the growth of leaves.

2. Striping propagation of dragon blood tree

1. Time

Striping needs to be carried out at a high temperature, usually from May to July, and the plants that carry out striping propagation usually have fewer branches and old leaves begin to fall after growing for many years. Of course, healthy dragon blood trees can also choose striping.

2. Operation steps

⑴ carries out circular peeling in the appropriate position of the trunk, keeping the width of the mouth at about 2 cm and the depth to the xylem. After peeling the skin with a tool, you need to insert the juice with a clean wet cloth, and then apply 5000-1000ppm of naphthalene acetic acid aqueous solution to the cortex at the upper end of the incision.

⑵ straps the bottom of the incision with a plastic bag to make the film into a funnel, which is then filled with soil, which can be made from a mixture of moss and mountain soil, and then watered thoroughly, fastening the upper end, and placing the plant in a well-ventilated and well-lit place.

⑶ carries on the maintenance management according to the normal dragon blood tree culture method, at the same time strengthens the fertilizer and water management, timely replenishes the water and fertilizer, after 30-40 days, the ring cutting site can grow new roots, and then can be separated from the mother for transplanting in September-October.
