Jasmine cutting hydroponics method
Jasmine is favored by horticulture enthusiasts for its elegant aroma and graceful plant shape. The hydroponic cutting method not only allows observation of the root growth process but also increases the success rate of propagation. This article explains the key hydroponic techniques for jasmine through four core steps, complemented by practical operation diagrams to help you cultivate robust new jasmine seedlings with strong roots.
One, scientific preparation of hydroponic equipment
1.1 Criteria for choosing transparent containers
It is recommended to use transparent glass bottles with a diameter of 5-8cm, which can promote root development due to their transparency and make it easy to observe water levels. Experimental data shows that the rooting rate of transparent containers is 37% higher than that of non-transparent containers.
1.2 Key points for water treatment
Use tap water that has been standing for 24 hours, and maintain the water depth at 2-3cm to keep the dissolved oxygen content. Adding 3 drops of hydrogen peroxide once a month can effectively prevent bacterial growth.
Two, advanced techniques for cutting branches
2.1 Criteria for selecting the mother plant
Choose semi-woody branches from the current year, as branches with flowers have a higher content of active substances. Cut 7-9cm long branches early in the morning, retaining 2-4 full leaves to maintain photosynthesis.
2.2 Professional pruning technique
Make a 45° diagonal cut at the base to increase the water absorption area, and keep the cut 0.5cm away from the node for easier rooting. Remove the lower leaves to prevent decay and retain the top leaf area to not exceed 15cm².
Three, intelligent cutting care system
3.1 Environmental parameter control
Maintain a water temperature of 22-28°C and 4 hours of scattered light daily. When the humidity is between 60%-75%, using a black-bottomed light-blocking bottle can stimulate root growth.
3.2 Water change cycle management
Change the water daily for the first 3 days, and then change the water twice a week. If mucilage is found, immediately disinfect with 0.1% potassium permanganate.
Four, optimization of hydroponic transfer system
4.1 Timing for transplanting
When the roots grow to 5cm and there are more than 3 lateral roots, it is time for transfer. The best transplanting time is between 9-11 am on a sunny day.
4.2 Setting for water-air balance
Use a siphon-type planting basket to keep 2/3 of the roots submerged. Add 5ml of foliar nutrient solution weekly, maintaining the EC value at 1.2-1.5mS/cm.
Through scientific hydroponic cutting management, the rooting rate of jasmine can reach over 90%. It is recommended to extend the lighting to 12 hours/day with LED grow lights, and regularly check the pH value between 6.0-6.5 to achieve annual cyclic cutting propagation.
