Fragrant genus Deciduous deciduous tree, native to Spain. The tree height is 10—12m. It blooms twice in May and July of the year. The flowers are bright and colorful, and the flowers are large and large. The flowers are hanging in a row. The ornamental value is high, and the flowering period is long. It is a city, a road, a scenic spot, etc. The greening treasures, for the first time gardening and ornamental tree species. The fragrant calyx is a rare green aroma tree species that is cold-tolerant, drought-tolerant, thin-tolerant, salt-tolerant, well-rooted, rapid-growing, and widely adaptable. It can be widely used in beautification of urban and rural areas, greening of barren hills, and has great value in landscaping. And high forestry economic value. Since the introduction of fragrant flowers from abroad is not long, as a new rare tree species, breeding seedlings is still a project with a high return rate within 5-7 years. Now its seedling cultivation techniques are described as follows: 1. Seedling propagation: Fragrant pods do not contain seeds, and they are usually propagated by buried roots and branches. The survival rate of twigs is low, and they are generally dominated by buried roots. 1 Buried root breeding selection of 1-2 years incense flower buds, lateral roots, diameter 0.5-1.5cm is appropriate. When taking the root, excavate the root 20cm away from the plant before budding or dig out the tree together with the root, leave the root 20cm long, and cut all the rest. Roots excavated and cut to avoid damaging the root bark, cutting sand or buried soil before dehydration. In April, the roots were taken out and cut into 8-10 cm roots. The roots were buried in the boring machine with a flat burial method. The depth was about 5 cm, and the row spacing was 0.3m1.0m. Strengthen water and fertilizer management, drought should be watered, and rain should be drained in time. Two sticks were used to select one-year-old hard-branches. The shoots were cut into 15cm-long cuttings in mid-April, and were soaked with ABT2 rooting powder at a concentration of 50mg/kg for 2-4 hours. The film was placed on a cutting plot to increase the temperature and moisturize the soil. The cuttings were inserted at an angle of 45 degrees in the trampoline to keep the soil moist. Buried or cutting seedlings can grow to 1.5-2m in the year. The fragrant buds breed quickly, and the rooted seedlings of the year were able to reproduce 50-60 strains of seedlings using the root insertion method in the second year. 2. Cultivation techniques: Transplanting should be carried out after falling leaves in autumn or before budding in spring. After the planting, it was watered in time, and then watered about 3 times depending on the drought conditions to ensure survival. The fragrant calyx has strong vitality and high planting survival rate. Transplanted seedlings need not be soiled or treated with chemicals. In order to make the seedlings grow robustly, the seedlings are transplanted and flattened from the ground to cut away 1,000 sticks from the ground and leave a strong bud from the base. After the flattening, the fragrant bud not only has a high survival rate, but also has a good tree shape and fast growth. Fragrant calyx grows naturally with a canopy, beautifully treed, and does not need to be trimmed. Planting tree height up to 2-3m, the main, lateral roots up to 2m, usually the second year after planting flowers. China Agricultural Network Editor
