6 key points for honeysuckle cutting
As a traditional Chinese medicinal material and ornamental vine, honeysuckle cutting propagation is an effective way to continue excellent varieties. Mastering scientific cuttage methods can not only maintain the characteristics of mother plants, but also quickly cultivate new seedlings. This article will analyze the cutting points of honeysuckle through six key links, focusing on the best cutting season and operation details. The best seedling breeding season for the core process of honeysuckle cuttage is selected for all seasons. However, when the temperature is stable at 18-25℃ in spring and autumn (March-April/September-October), the branches are rich in nutrients, and combined with 65%-75% environmental humidity, rapid rooting can be achieved in 15 days. High temperatures in summer require awnings, and greenhouse insulation is needed in winter. The selection standard for high-quality cuttings is to select semi-lignified branches of the current year with a diameter of 0.3- 0.5 cm. The principle of "two sections and three buds" is adopted: 2 nodes and 3 bud points are reserved for each section, 2 real leaves are reserved at the top for photosynthesis, and the bottom is chamfered 45 degrees to increase the water absorption area. The cutting pretreatment process uses 1000ppm naphthylacetic acid solution to soak the base for 2 hours and disinfect it with 500 times carbendazim solution. Focusing on the formation of callus at the incision can increase the rooting rate to more than 90%. Recommended matrix ratio and disinfection formula: perlite: vermiculite: humus =3:2:5, adding 50g of slow-release fertilizer per cubic meter. The matrix was poured through with 0.1% potassium permanganate solution, and the film was sealed and sterilized for 3 days. Cutting operation specifications The scientific cutting method adopts the "hole insertion method": use a wooden stick with a diameter of 1 cm to pre-punch holes, and the insertion depth is 1/2-2/3 of the cutting. Keep the density at 5×5cm. Too dense may cause mildew. The optimal oblique insertion angle is 60 degrees to promote the base to contact the moist substrate. Intelligent environmental control builds a small arch shed to maintain 85% humidity and configures a sun screen with a shading rate of 70%. Use an intermittent spray system for 10 seconds every 2 hours. Maintain the moisture content of the substrate at 40%-50% during the rooting period to avoid stagnant water and root rot. Maintenance and management after rooting When the new roots grow to 3 cm, gradually increase the light intensity. Apply 0.1% urea +0.2% potassium dihydrogen phosphate foliar fertilizer for 10 days every time. After 60 days, it can be transplanted to a nutrient bowl and used as a transitional substrate with peat soil: garden soil =7:3.
By accurately controlling cuttage time, standardizing operating procedures, and scientifically controlling the environment, a survival rate of more than 95% of honeysuckle cuttage seedlings can be achieved. Growers are recommended to establish a cuttage log to record data such as temperature, humidity, and number of rooting days to continuously optimize the seedling system.
