Method of Breeding Flying Dragons
Flying dragons, as a representative species of the Euphorbiaceae family of succulents, are favored by gardening enthusiasts for their unique fleshy stems and ornamental value. This article systematically explains the three main breeding methods of flying dragons, combining practical experience to expand technical details, helping you easily grasp the essentials of plant propagation.
Core Methods of Breeding Flying Dragons
Key Points of Grafting Propagation Technique
Spring to early summer is the best period for grafting, and it is recommended to choose robust rootstocks such as霸王鞭 (Bauhinia). The scion should be a mature fleshy stem segment with a diameter of over 3cm, retaining at least two growing points. When using the splice grafting method, the top of the rootstock is cut into a V-shaped groove, and the scion is cut to match the protrusion, ensuring the cambium layers fit tightly. After grafting, cover with a bag to keep it moist for 15 days, maintaining the ambient temperature at 25-28°C, and gradually increase light exposure after callus formation.
Standard Operation of Seedling Germination
After harvesting, seeds need to be dried in the shade for 3 days. The sowing matrix should be prepared with peat and perlite in a ratio of 3:1, adjusting the pH to 6.0-6.5. Use the plug sowing method, placing 1-2 seeds per hole, with soil coverage twice the diameter of the seeds. Maintain the matrix moisture at 60%-70% and set up a small arch shed to maintain 80% air humidity. After seedlings emerge, spray 0.1% potassium dihydrogen phosphate solution weekly, and transplant when they have 3 true leaves.
Full Process of Cutting Propagation
Select semi-woody stem segments, 8-12cm in length. The cut ends should be sealed with wood ash to prevent milky sap, and left to scab for 2 days. Use a mixed matrix of vermiculite and coarse sand after high-temperature sterilization, with the cutting inserted into the soil to a depth of 1/3. Maintain scattered light for the first 10 days, with a day-night temperature difference of 8-10°C during the rooting period. Using ABT rooting powder at a concentration of 1000 times can increase the survival rate to over 90%.
Key Points of Flying Dragon Breeding Management
All breeding methods require attention to: maintaining good ventilation with an air flow speed of 0.3-0.5m/s; using 50% shade netting in the early breeding stage; keeping the matrix EC value at 0.5-0.8mS/cm; regularly checking the cut ends to prevent fungal infections. Grafted seedlings need to be tied and fixed for 45 days before untieing, and cutting seedlings should start hardening off after 20 days.
By systematically mastering the three propagation techniques of grafting, sowing, and cutting, combined with precise temperature and humidity control, large-scale production of flying dragons can be achieved. It is recommended to prioritize the cutting method for home breeding, grafting for large-scale production, and seed propagation for variety improvement. Regularly observe the plant condition and scientifically adjust management measures to obtain high-quality flying dragon seedlings.
