How to Cultivate Honeysuckle Seedlings
Do you know this? How to cultivate honeysuckle seedlings and the knowledge of green plant flowers in the aspect of honeysuckle cultivation techniques will be introduced by the editor next.
Honeysuckle has strong adaptability to growth, with well-developed roots, cold resistance, drought resistance, and thin soil tolerance. It is an ideal ecological species for windbreak and sand fixation, preventing soil and water loss, landscaping, and barren hills and slopes in arid and semi-arid areas, with a broad development prospect.
1 Selection of Seedling Raising Bed
Choose a field with good irrigation and drainage conditions. Before seedling raising, deeply cultivate the land, apply a certain amount of decomposed organic fertilizer and compound fertilizer of nitrogen, phosphorus, and potassium as a base fertilizer, clear the weeds and stones in the field, level and rake the land, and make it into a ridge 1 to 1.5 meters wide for sowing.
2 Seedling Raising Methods
Honeysuckle has two methods of seed propagation and cutting propagation. To improve the germination rate of seeds, soak the seeds in warm water for 2 hours before sowing, then soak them in 30℃ water for 20 hours, drain the water after drying, and sow with a row spacing of 20 cm. You can also use nutrient钵 seedling raising, choosing a nutrient钵 with a height of 12 cm and a diameter of 8 cm. After sowing, cover the ridge surface with a 1 cm thick layer of straw and then water sufficiently.
Cutting propagation is carried out in spring and autumn each year, selecting healthy branches of 1 to 2 years old as cutting materials. The length of cuttings is usually 25 to 30 cm, with 2 to 3 internodes reserved. Generally, choose to raise seedlings in early August, selecting high-quality, robust one-year-old branches. Before cutting, soak the cuttings in rooting powder for 15 to 20 minutes and then dry them. Insert them vertically or obliquely with a row spacing of 25 cm × 3 cm and a depth of 20 cm, leaving 8 to 10 cm above the ground. According to the actual situation of the cuttings, provide shading and irrigation management. In dry periods, water can be done every 48 hours to promote root formation after 15 days.
3 Field Transplanting
In the Gansu Longzhong area, spring transplanting is generally chosen. To improve the survival rate of transplanting, follow the principle of "transplanting immediately after digging." Choosing continuous cloudy or sunny afternoons can effectively improve the survival rate. Before transplanting, determine the plant spacing and row spacing, perform fixed-hole planting, plant one strong seedling in each hole, firm the soil after transplanting, water sufficiently, and then cover with plastic film to prevent weed growth and improve soil moisture retention. After 7 to 10 days, water and supplement water according to the soil moisture content.
4 Field Management
4.1 Scientific Fertilization: According to the growth period and growth vigor, fertilize scientifically. In November each year, apply a base fertilizer mainly of farm manure, 3 to 5 kg per flower墩; at the same time, manage top dressing according to different growth stages, mainly using decomposed animal and human waste, wood ash, etc.; after 3 years, apply a certain amount of soil manure and phosphate fertilizer; after the first season of honeysuckle harvest, apply top dressing again, mainly using compound fertilizers of nitrogen, phosphorus, and potassium.
4.2 Irrigation and Drainage: Although honeysuckle is a relatively drought-tolerant plant, its growth will be affected if it does not rain for a long time. In conditional planting areas, measures such as淋灌, spray irrigation, or even flooding can be taken to avoid irreversible drying and withering of honeysuckle seedlings. Additionally, honeysuckle is not tolerant to waterlogging, so timely drainage should be carried out when there is excessive rainfall in summer.

4.3 Regular Weeding: Generally, 3 times of tillage and weeding can be carried out, weeding once during the germination period of honeysuckle, once in July to August each year, and once in late autumn or winter. During tillage and weeding, effective protection of the plants must be strengthened to prevent the honeysuckle roots from leaving the soil. After each weeding, remove the weeds clean and take them out of the field.
4.4 Shaping and Pruning: For young honeysuckle plants 1 to 2 years old, shaping is mainly carried out, selecting a thick and upright branch as the main stem for cultivation, and timely pinching when it grows to 25 cm to promote lateral branch growth. After the lateral branches sprout, remove the lower part of the long branches and handle the pruning. Retain 3 to 4 strong and upright branches on the main stem, thinning out weak branches that grow inward or are long. Pruning during the full bloom period mainly involves pruning withered and diseased branches, mainly shortening the medium-length branches to ensure an 8 to 10 cm spacing between branches.
4.5 Disease and Pest Control: The main diseases are powdery mildew and rust. In the early stage of the disease, spray 20% triazole ketone emulsion 400 to 500 times, once every 7 to 10 days, for a total of 2 to 3 times.
The main pests are Hyalophora cecropia and aphids. In the non-flowering period, you can use 50% omethoate 1,000 to 1,500 times or 25% fenvalerate emulsion 2,500 times for spraying.
5 Harvesting and Processing
The timing of harvesting honeysuckle is one of the most important measures to ensure its quality. When the flower buds turn from green to white, with the upper part swollen but not yet open, it is the most suitable time for harvesting. "Two white flowers" and "big white needles" are the best commercial traits of honeysuckle. Additionally, the ideal time to harvest honeysuckle is in the morning, after which it can be dried in a dryer, or dried in the sun or wind. When drying, the temperature should be appropriate. If the temperature is too low, the drying effect is poor; if the temperature is too high, it can easily turn black and lose its medicinal value and efficacy.
