Dragon Blood Tree
About the dragon blood tree and its related content, the propagation methods of the dragon blood tree (Dragon Iron), the specific details are as follows:
The propagation methods of Dragon Iron: After the dragon blood tree was introduced to our country, except for a few tropical areas that produced seeds, other areas mainly adopt the methods of air-layering and cutting for asexual propagation.
(1) Air-layering propagation The stems of the dragon blood tree mostly grow upright with few branches. After several years of growth, the base leaves fall off, naturally losing their ornamental value. In this case, cultivators can perform air-layering propagation during the hot and humid season from May to July.
The method is: Make a circular incision at an appropriate position on the stem of the plant, with a ring mouth width of 1.8-2.2 centimeters, deep into the xylem, and then strip off the bark around the incision with a small knife. Wipe away the juice oozing from the cut surface with a clean damp cloth, apply a solution of naphthylacetic acid at a concentration of 5000-10000 ppm to the upper epidermis of the cut, then wrap the lower part of the cut with white plastic film, shape it into a funnel, fill it with a mixture of moss and mountain soil as the rooting substrate, wrap the cut with the knife, water thoroughly, tie the upper part of the film tightly, and then place the plant in an outdoor cultivation environment, strengthening fertilization and water management. After the dragon blood tree is air-layered, it is necessary to check whether the matrix is dry at any time and supplement water as needed. Generally, after 30 to 40 days of cultivation, new roots appear at the incision site, and by September to October, they can be cut from the mother plant and cultivated separately as an independent growing plant.
(2) Cutting propagation The dragon blood tree can also be propagated asexually by cutting, usually from May to June. This is the vigorous growing period of the dragon blood tree, and the plant is rich in nutrients, making it easy to survive after cutting.
Before cutting, select a mother plant with high ornamental value and take its strong branches that have grown for more than two years, each about 10-20 centimeters long, with or without leaves. The base of the cutting is cut flat, the top is cut horizontally, leaves are retained, the upper and lower cuts can be soaked in clean water to wash away the overflowing juice, placed in a shady and well-ventilated place to dry for a while, then soak the base of the cutting 2-3 centimeters deep in a solution of 500-1000 ppm naphthylacetic acid for about 5 seconds, then insert immediately after soaking.
For dragon blood tree cutting, the seedbed can use a small-sized terracotta pot, the matrix can use vermiculite, perlite, or high-temperature disinfected sandy soil. After potting, cuttings are performed. One plant per pot, water thoroughly after cutting, place the seedbed in a shaded and sunny area, and take good care. The main management task afterward is to keep the matrix moist. The dragon blood tree heals quickly, roots early, and germinates rapidly. Generally, after 15 to 20 days, the cut surface forms callus under the action of wound hormone, and after 25 to 35 days, the cutting quickly forms the primitive root under the action of endogenous hormone. By 35 to 40 days, new roots can germinate, and after two months, the plant can be transplanted into the pot with cultivation soil.
The above is[] some experience and knowledge about the propagation methods of the dragon blood tree (Dragon Iron). I hope this article can bring you some help!
