Cutting method of Euphorbia chinensis
As a star variety in the succulent family, Euphorbia Pavilion Brocade is favored by gardening enthusiasts for its unique mottled brocade texture. However, many novices often encounter problems such as stem rot and difficult root growth during cuttage propagation. This article will systematically analyze the four key steps of cutting Euphorbia japonica, and cooperate with exclusive picture demonstrations to help you easily master this precious and fleshy breeding mystery. 1. Core skills for substrate configuration 1.1 Substrate selection standard The root system of Qiangge brocade is extremely sensitive to water. An ideal substrate needs to meet the golden ratio of air permeability and drainage. It is recommended to use a three-in-one formula of red jade soil (40%)+ vermiculite (30%)+ coarse river sand (30%). This structure can not only quickly divert excess water, but also maintain necessary humidity through vermiculite particles. 1.2 Key points for substrate treatment Before use, the substrate needs to be exposed to the sun for 2-3 days, or high-temperature steam sterilization method needs to be used to eliminate bacteria. The treated substrate needs to maintain a humidity of about 40%, and the best state is to form a ball with your hands and disperse with a light touch. 2. The whole process of stem segment treatment 2.1 The best time to collect materials is from 9:00 a.m. to 11 a.m. in sunny spring and autumn, when the plant cell activity is the strongest. Select a strong stem section with a diameter of more than 1 cm and 3-4 growing nodes, and use alcohol-disinfected elbow scissors to cut at a 45° angle to ensure a smooth incision. 2.2 Tips for juice treatment Immediately after cutting, use a sterile cotton swab to absorb the milky white juice exuding from the wound, place it in a cool and ventilated place to dry for 24-36 hours, and wait until the incision forms a translucent callus before cutting. This process can effectively prevent bacterial soft rot. 3. Scientific cuttage operation guide Insert the pretreated stem segments vertically into the substrate 2-3cm deep, and fix them using the "three-pressing and one-lifting" method: the first time, fill the soil to 1/3 of the hole depth, gently press, and the second time to 2/3 of the hole depth to strengthen fixation., finally, the surface layer is covered with soil, gently lift the plant to ensure that the root system stretches. After completion, spray 800 times carbendazim solution for environmental disinfection. 4. Intelligent Maintenance Management System 4.1 Light Temperature Control Strategy It is necessary to maintain 2000-3000lux of scattered light for the first two weeks after cuttage, and the ambient temperature is stable at 22-25℃. You can use the sunshade net to adjust the light intensity and monitor it in real time with a thermometer. 4.2 The water management cycle adopts the "alternate dry and wet" irrigation method: after the first thorough irrigation, water will be replenished again when the substrate moisture content drops to 15%(which can be detected by a soil hygrometer). Keep the air humidity at 60%-70% for the first 30 days, and precise control can be achieved through a timed spray device. 4.3 New aerial roots are usually visible within 15-20 days after root development observation, and the duration of direct light can be gradually increased at this time. If there is still no root development after 45 days, you can carefully pull it out for inspection, remove the rotten parts, and then re-heal the callus.
Through scientific substrate ratio, standardized stem segment treatment, precise cuttage operations and intelligent maintenance management, the survival rate of Euphorbia japonica cutting can be increased to more than 85%. It is recommended to conduct cutting records every quarter, establish a dedicated maintenance database, and gradually form a personalized breeding system. After mastering these core skills, you can not only successfully breed Euphorbia japonica, but also expand and apply these experience to the cultivation practice of other succulent plants.
