1, growth environment
Jacaranda Jacaranda is an environment that likes high temperature, humidity and plenty of sunshine. Not cold-resistant, not drought-resistant, not tolerant. It likes deep soil, especially neutral to slightly acidic loam with good drainage. The suitable growth temperature is 22∽30 degrees. If the temperature is lower than 15 degrees in winter, the growth will stagnate, and if the temperature is higher than 32 degrees in summer, the growth will also be inhibited.
2. Soil treatment
Before planting jacaranda, you must choose the right soil. It is recommended to use soft and breathable soil, which can be deeply ploughed and properly watered to keep the soil moist. Add a small amount of decomposed farm manure to increase soil fertility. In addition, it is necessary to spray an appropriate amount of carbendazim solution for disinfection and sterilization to ensure a high survival rate.
3. Planting method
Jacaranda jacaranda is usually planted in spring and summer, and the suitable row spacing is1.0 ~1.5m. First, the decomposed organic fertilizer is applied to the planting hole as the base fertilizer, and then jacaranda soil balls are planted in the dug planting hole, and the seedlings stand upright. After backfilling, gently compact and thoroughly water. Bamboo poles can be inserted for light binding to guide plants to grow upright. After survival, you can not water or water less in rainy days, and you need to increase water in hot rainy days.
4. Daily water and fertilizer
The watering amount of jacaranda needs to be judged according to the growth of the plant. If the plants are dry and short of water, water them in time. Pay attention to the need to control the amount of watering during the growth period to avoid the problem of water accumulation caused by excessive watering. After the jacaranda jacaranda survived, it was fertilized once every 3 ~ 4 months, and 20 grams of ternary compound fertilizer and 0/0 gram of urea/kloc were applied to each hole.
5. Dressing and shaping
The trunk of jacaranda is erect and slender, with few branches. When the tree is 3 meters high, it should be pruned in early spring. The trunk height is 2.2 ~ 2.5 meters, which can effectively promote the growth of branches. In the future, it will be trimmed and reshaped once a year in early spring to form a good crown, with more branches and more flowers.
6, pests and diseases
Diseases of Jacaranda jacaranda are generally rare, and the common diseases are mainly insect pests, mainly longicorn beetles. The mixed solution of 10 quicklime and 1 0 sulfur and salt can be applied below 80cm at the base of the trunk to prevent adults from laying eggs.
The above is the introduction of the planting method of jacaranda. At present, jacaranda is used as a street greening tree in many areas, and some people will plant it in the yard. When it blooms, it has very high ornamental value and is very beautiful. Therefore, I like jacaranda, and I can try to plant it.
