House 卷 Leaf Insertion Method
As a rare variety of succulent plants, House Roll Silk is deeply loved by gardening enthusiasts for its unique curled leaves. Leaf insertion, as the most economical propagation method, mastering the correct technique can increase the survival rate to over 80%. This article will systematically analyze the full process skills of House Roll Silk leaf insertion from five key dimensions.
One, Best Time for Cutting Selection
1.1 Seasonal Temperature Control
In late spring and early summer (April-June), when the average daily temperature is 20-25°C, the mother plant is in a period of vigorous growth with sufficient leaf nutrient reserves. At this time, maintaining the air humidity at around 60% can effectively prevent cut decay.
1.2 Special Climate Treatment
In the south, it is recommended to delay until late May during the plum rain season, while in dry northern regions, a humidifier can be set up in advance. In winter, supplementary lights are needed to maintain 12 hours of daylight per day.
Two, Key Steps for Leaf Treatment
2.1 Selecting Healthy Parent
Choose adult plants that are over 2 years old and pick the middle, full, and plump leaves. Retaining a 0.5cm stem segment at the base can increase the germination rate, and be careful not to damage the growth point.
2.2 Scientific Disinfection Process
Wipe the cutting tool with 75% alcohol and apply carbendazim powder to the wound. Let it air-dry in a shady and well-ventilated place for 3-5 days until a protective film forms on the cut, which can reduce the probability of black rot by over 50%.
Three, Substrate Ratio Optimization Scheme
3.1 Basic Formula Suggestions
Coarse river sand, red jade soil, and vermiculite should be mixed in a ratio of 5:3:2, with particle size of 2-3mm being ideal. Boil with boiling water for sterilization before use and wait until it cools completely before using.
3.2 Moisture Control Techniques
Keep the substrate moisture content between 30%-40%, with the best state being able to form a ball when held in hand and scatter immediately upon release. Excess moisture can cause leaf rot, while too dry is not conducive to root development.
Four, Precise Insertion Operation Guide
4.1 Scientific Use of Rooting Hormones
Use 1000 times solution of indolebutyric acid (IBA) for quick dipping treatment, which can shorten the rooting time by 7-10 days. Note that the area of the medicine in contact should not exceed 1/3 of the petiole length.
4.2 Angle and Depth Control
Insert the leaves at a 30° angle, with a depth of 1-1.5cm into the soil. Keep the leaf surface upwards with a spacing of at least 5cm to prevent disease transmission.
Five, Intelligent Maintenance Management Scheme
5.1 Light Control Strategy
Initially, place it in a scattered light environment of 5000-8000 lux, and gradually increase to 15000 lux after 20 days. Use a shade net to adjust and avoid strong midday sunlight burns.
5.2 Water Supply System
Use a mist喷淋 device, spray twice a day, morning and evening, each for 3-5 seconds. Maintain the air humidity at 70%-80%, and the surface of the matrix should be slightly damp.
Through the above systematic leaf insertion management, House Roll Silk usually forms complete roots in 3-4 weeks, and new buds can be seen after 2 months. It is recommended to record the growth status every 15 days and adjust the maintenance plan in a timely manner. With proper fertilization (EC value controlled at 1.0-1.2mS/cm), healthy seedlings can be obtained within half a year.
