Sorbus Huashan

Jacaranda, with a tall crown and a plant height exceeding15m, has alternate leaves, bipinnately compound leaves and tiny pinnate leaflets, which are quite beautiful. A terminal or axillary panicle with many flowers, dark blue or purplish blue, covered with branches, is extremely spectacular. Each string of flowers can be up to 20 cm long, and dozens of flowers are bell-shaped. capsule

Propagation: Jacaranda jacaranda is propagated by seed and cuttage tissue culture. Its capsule maturity is 1 1 month. After harvesting, it is exposed to the sun or piled up in a windless place. After drying, it is stored until March of the following year. When the temperature is about 20℃, the seed germination rate is only about 5%. Cutting propagation of Jacaranda jacaranda can be carried out in spring and autumn, and the medium-mature branches are selected as cuttings with high rooting rate. Tissue culture of jacaranda is also easy. Some scientific research units in China have used the shoot tips and stem segments of seedlings as explants to breed a large number of test-tube seedlings.

Cultivation: (1) Temperature and light: Jacaranda is native to tropical America, and likes warm, humid and sunny environment, and is not resistant to frost and snow. The suitable growth temperature is 22-30℃. If the temperature is lower than 15℃ in winter, the growth will stagnate. Lower than 3-5℃ will be cold, and higher than 32℃ in summer will also inhibit growth. I like light, but I can tolerate half yin. (2) Soil and fertilization; For sandy loam or loam that likes to be fertile and moist, sufficient base fertilizer should be applied when planting. After survival, topdressing 1 time in spring and autumn, pruning once a year in early spring, and pruning the aged plants again. When potted, it can be cut off or grafted and dwarfed, and watering and nitrogen application can be controlled. (3) Pest control: Jacaranda jacaranda has fewer diseases, and the main pest is Cerambycidae. If reddish-brown dung scraps are found at the base of the trunk, the bark cortex can be lifted with a knife to catch larvae; You can also apply 10 part of quicklime and 1 part of a mixture of sulfur and salt below 80 cm at the base of the trunk before the adult occurs to prevent the adult from laying eggs.
