Spring Colt Cutting Method
As a unique variety among succulents, the cutting propagation of Spring Colt is the cultivation technique most concerned by horticulture enthusiasts. This article will systematically explain the precautions of five key stages from environmental control to operational details, and is specially accompanied by practical operation diagrams to help you easily master the core skills of asexual propagation of Spring Colt.
Ⅰ. Choosing the Cutting Time
1.1 Seasonal Temperature Control
The best cutting period is from May to September when the day-night temperature difference is less than 8°C, and the substrate temperature is stable at 18-25°C for the highest survival rate. Avoid the noon period during high summer temperatures, and it is recommended to use heating equipment in winter to maintain the root development environment.
1.2 Air Humidity Management
Coordinate temperature adjustment to maintain 60-75% air humidity, and use a timed misting device to prevent long-term leaf accumulation of water that could cause fungal infections.
Ⅱ. Preparing Professional Tools
2.1 Disinfection Key Points
Soak the cutting tool in medical-grade alcohol for 30 minutes, and apply freshly prepared carbendazim suspension (0.3% concentration) to the cut surface, which can effectively prevent bacterial soft rot.
2.2 Configuring Protective Equipment
Ⅲ. Cutting Treatment Technology
3.1 Standard for Branch Selection
Select two-year-old semi-woody branches with a diameter greater than 0.6cm and 3-4 growth nodes, and cut to a length of 8-12cm.
3.2 Wound Healing Treatment
Make a 45-degree oblique cut and place in a shaded and well-ventilated area for 48 hours, then proceed with cutting after forming a distinct callus.
Ⅳ. Optimizing Substrate Formula
4.1 Improving the Sand Bed Structure
Use a mixed substrate of perlite: vermiculite: peat in a ratio of 3:2:1, with a铺 thickness of 15cm, and a 2cm layer of ceramic stones at the bottom for drainage.
4.2 Sterilization Process
The substrate must be sterilized with high-temperature steam, then cooled and adjust the pH value to 6.0-6.5, with an EC value less than 0.8mS/cm.
Ⅴ. Post-Cutting Care
5.1 Environmental Control Parameters
Maintain a light intensity of 5000-8000Lux, use an intermittent misting system to keep the leaf surface moist, and apply seaweed nutrient solution (diluted 1000 times) every week during the new root germination period.
5.2 Timing for Transplanting
When new roots reach 5cm or more and secondary branches appear, it is time to transplant to the formal cultivation substrate.
Through scientific temperature and humidity management, standardized instrument disinfection, precise cutting treatment, optimized substrate formula, and systematic post-care, the survival rate of Spring Colt cuttings can be increased to over 85%. It is recommended to replace the cutting substrate every quarter, regularly test the EC value, and use plant growth regulators in combination to achieve large-scale efficient propagation.
