Sowing, cutting, stacking soil and layering, and dividing plants for propagation. Generally, cutting and soil piling are the main methods, and cutting with branches is easy to survive. When the temperature is right, it can be cut all year round. Take a stout vine with a length of 10 ~ 15 cm and insert it into the matrix of vermiculite: perlite: yellow sand =1:1. The cutting depth is 65438+ 0/2 of the cutting length. Stacking and layering: before layering, cut off the cortex at the base of the branch, and then pile the culture soil for 20 ~ 30 cm, and keep the culture soil moist all the time. Planted after rooting, cut off from the mother plant and cultured separately.
Seed propagation
When the seeds are ripe in autumn, collect the ripe fruits, knead them in clear water, remove the peels and impurities, take out the full seeds that have sunk to the bottom of the water, and dry them for preservation. Autumn can be harvested or planted. If the seeds are sown in the following spring, the sand storage method can be used to treat the seeds for overwintering, and then the seeds can be planted after being frozen in the spring. Trenching on the seedbed, evenly spreading seeds into the trench, covering with 3 cm thick soil, compacting, and emerging in about 10 days. Field management should be strengthened at seedling stage, and seedlings can be sown in production fields in autumn or spring of the following year. The sowing amount per mu is about 1- 1.5 kg.
Cultivation management
1. culture medium: although honeysuckle does not require much soil, it will grow better if it is cultivated with 60% ~ 70% peat, 20% ~ 30% vermiculite and 10% perlite.
2. Water and fertilizer management: 3 months before flowering, apply phosphorus and potassium-based fertilizer 1 ~ 2 times. After the flowers wither in late May, we should still apply 1 ~ 2 times of thin fertilizer, properly remove the new branches and promote the germination of the second batch of flower buds. At the same time, the soil should be kept moist and not too dry, otherwise the basal leaves will wither and fall off easily, which will affect flowering. In hot season, avoid direct glare to avoid burning young leaves.
3. Pruning: Prune once in its dormant period, cut off slender branches, weak branches and cross branches, and shorten the branches of the current year to promote new branches and flowers in the coming year.
4. Pest control: There are relatively few pests and diseases in honeysuckle, and aphids occasionally invade, which will damage new leaves and shoots, turn the leaves over and affect growth. Use 65,438+0,000 times of "aphids and ticks" or other pesticides to control it.
Honeysuckle not only has high ornamental value, but also has high economic value. It is often used as honey source and medicinal plant cultivation. Its flowers, stems and leaves are very resistant to a variety of germs and influenza viruses.
Dwarfing measures of potted honeysuckle
Honeysuckle is a perennial semi-evergreen vine of Caprifoliaceae, which blooms from May to August with unique fragrance and can be used to make honeysuckle tea.
Honeysuckle can be used as hedges, fences, balconies, flower galleries, flower stands and other three-dimensional greening in parks, and can also be used as ground cover materials for soil and water conservation, wind prevention and sand fixation. Honeysuckle. Can be planted in the ground, can also be used as a potted plant to watch. The flower stems of gold and silver are slender, and the tree shape is generally difficult to control, which is prone to the phenomenon of long nodes and few flowers. Therefore, dwarfing measures must be taken to make gorgeous and spectacular honeysuckle bonsai.
1. control water and fertilizer honeysuckle potted plants must limit vine growth, control tree shape and increase flower quantity. Avoid rain in spring, reduce watering, prevent overgrowth, make stems and vines mature, shorten internodes, and reduce plant deformation. Apply less or no nitrogen fertilizer before flower bud formation, and increase phosphorus and potassium fertilizer to promote flower bud formation and increase flower quantity. Proper application of nitrogen fertilizer in the period of branch stop and bud pregnancy will make the flowers big and bright.
2. Change pots at the right time. Generally, potted flowers are changed into one pot every two years, and honeysuckle bonsai is changed into one pot every three or four years. Because of the few times of changing pots, the absorption function of roots is weakened, which promotes plant senescence, inhibits excessive growth, eases the tree potential, makes the stems and vines strong, makes the internodes dense, dwarfs the plant shape and makes flowers flourish.
3. Be a tender branch of Lonicera japonica Thunb. To control the germination of about 5 cm, 700- 1000 ppm paclobutrazol, 2000-4000 ppm MB9 or 1000-2000ppm chlormequat should be sprayed or sprayed continuously for several times to prevent the stem from growing vigorously and dwarf the tree.
4. Dwarf plastic pruning: Dwarf plastic pruning is carried out from the upper pot planting and cultivated into thick stems and short branches. During the growth period, vigorous buds should be removed, strong branches should be cored early, long branches should be cut off and short branches should be kept when pruning. Through shaping and pruning, the vine winding type is transformed into a short shrub pile landscape with short branches and short stems, uniform and dense branches and obvious layers.
5. Long-term treatment of honeysuckle is a plant that likes light and long-term sunshine. If the environment is poorly ventilated and humid, the stems and vines will grow white, the branches will be thin, the leaves will easily turn yellow and fall off, and there will be few flowers. Therefore, honeysuckle bonsai should be placed in a sunny place, preferably in direct sunlight all day, so as to make the branches stout and short, the leaves luxuriant and the flowers numerous, and prolong the flowering period.
