Can honeysuckle be planted with cuttings?
You may not know whether honeysuckle can be planted with cuttings and how to maintain green plants and flowers. Let me take you to understand them.
Can honeysuckle be planted with cuttings? How to maintain it? The answer is yes. As a highly adaptable Chinese medicinal material, honeysuckle has a cuttings survival rate of more than 70%. March to May in spring or September to October in autumn is the best time for cuttage. At this time, the temperature is stable between 15-25℃ and the humidity is maintained at about 60%, which is conducive to the rooting and development of cuttings.
1. Scientifically select cuttings to ensure survival rate 1. The branch selection standard should be 1-2-year-old semi-lignified branches, with a diameter of 0.3- 0.5 cm. Experiments at Jiangxi Agricultural University have confirmed that the rooting ability of branches taken from the middle and upper parts of the mother plant is 35% higher than that of the base branches. Each cutting section retains 2-3 nodes, and the most suitable length is 8-12cm. 2. The key points for incision management are to make a flat incision 1cm away from the bud eye, and the lower incision is oblique at 45° to increase the absorption area. Data from the Shandong Academy of Traditional Chinese Medicine show that the rooting rate of cuttings soaked in 500mg/L indolebutyric acid for 10 seconds can reach 82% after 20 days. 2. Matrix preparation and disinfection process 1. The ideal substrate formula is mixed with river sand: vermiculite: humus soil in a ratio of 5:3:2, and the pH value is adjusted to 6.0-6.5. Tests at Fujian Agriculture and Forestry University showed that the root system development rate under this formula was 40% faster than that of pure garden soil. 2. The key steps of disinfection require triple disinfection treatment: -exposure to sunlight for 48 hours-pouring through with 0.2% potassium permanganate solution-steam sterilization for 30 minutes, which can reduce the incidence of soil-borne diseases by more than 90%. 3. Precise cuttage operation specifications 1. The cutting depth is controlled by 2/3 of the length of the insertion substrate, and 1-2 bud points are retained on the ground. Observations by the Zhejiang Academy of Agricultural Sciences found that the survival rate of transplanting too shallow cuttings (<3 cm) is only 61%, while the standardized depth can reach 89%. 2. Density management standard row spacing is 8cm× plant spacing is 5 cm, 250 plants can be cut per square meter, which not only ensures ventilation but also makes full use of space. Pour root water immediately after cuttage to maintain the moisture content of the substrate at 60%-65%. 4. Intelligent environmental control system 1. Temperature and humidity management Build a small arch shed with a height of 80cm, and cooperate with the spray system: -Day temperature 22-25℃-Night temperature 15-18℃-Air humidity 75%-80%. Beijing Academy of Agriculture and Forestry Sciences Monitoring shows that in this environment Calli formation time can be shortened to 7-9 days. 2. The light regulation plan shades 70%-80% in the early stage, and gradually reduces to 50% after 20 days. Research from Nanjing Agricultural University shows that moderate shade can increase leaf photosynthesis efficiency by 25%, avoiding excessive transpiration caused by strong light. 5. Fine maintenance during the rooting period 1. Water management adopts the principle of "seeing dry, seeing wet", and water is replenished when the substrate surface becomes white. Experimental data from China Pharmaceutical University show that intermittent spraying (15 seconds every 2 hours) develops better than continuous moisturizing of roots. 2. Nutrient supplementation strategy sprayed 0.1% potassium dihydrogen phosphate every week after taking root. Tests by Anhui College of Traditional Chinese Medicine showed that this treatment could increase the number of lateral roots by 40%. It was found that after the new leaves were unfolded, amino acid water-soluble fertilizer diluted 1000 times could be topdressing. 6. Key technical points of transplanting 1. The best time to transplant is when the new roots grow to 3-5cm and secondary branches appear, usually 3 - 5 -45 days after cuttage. According to statistics from the Guangxi Medicinal Botanical Garden, the survival rate of transplanting at this time is 28% higher than that of transplanting in advance. 2. The transplanting operation procedures are carried out on cloudy days, and transplanting with soil to a nutrient bowl with a diameter of 15cm. The substrate was changed to garden soil: humus soil: perlite =6:3:1, and the seedlings were slowly cultivated for 5-7 days after planting. 7. Comprehensive pest control 1. Common disease management-powdery mildew: spray 25% triadimefon 1500 times solution in the early stage of the disease-root rot: irrigate 50% carbendazim 800 times solution Yunnan Plant Protection Station recommends that monthly rotation of medication can reduce drug resistance by 70%. 2. The pest control plan uses 10% imidacloprid at 2000 times for aphids, and sprays 1.8% abamectin at 3000 times for red spiders. Using yellow plate traps can reduce the use of chemicals by 60%. 8. Essentials of reshaping and pruning 1. During the growth period, pruning will pick the new shoots when they grow to 20cm to promote the development of lateral branches. Data from the Henan Academy of Agricultural Sciences shows that secondary picking can increase flowering volume by 50%. 2. Winter pruning techniques retain 3-5 main branches and 4-6 short shoots per branch. Remove excessively dense branches, insect and insect branches to keep the light transmission rate of the plant above 60%. Through the above-mentioned standardized cuttage process and precise maintenance and management, honeysuckle cuttage seedlings can generally enter the high-yield period in the second year, realizing dual benefits from medicinal material harvesting and ornamental value. Note that different areas need to adjust management details according to local climate characteristics. For example, drainage needs to be strengthened in rainy areas in the south, and soil and cold prevention measures need to be taken in winter in cold areas in the north.
The above describes whether honeysuckle can be planted by cuttings and how to maintain it for your reference.
