Like light, but also resistant to shade, in the seedlings should have a certain degree of shade. The demand for soil is not high, like the slightly acidic soil with high dryness and rich humus, especially the sandy soil with deep, fertile and moist soil and good drainage. Do not tolerate drought and barren soil, avoid saline-alkali soil and waterlogged land, planted in poorly drained wetlands, will cause poor growth, root rot, leaf shedding, and eventually lead to the death of the whole plant.

Propagation methods of Cinnamomum chinense

1. Grafting: Ligustrum lucidum, lobular privet, ash and tassel can be used in rootstock. Lobular privet is often used in mass reproduction. Before spring germination, the rootstock is cut from 5 cm above the ground. The sturdy branches of sweet-scented osmanthus 1 to 2 years old are 10 to 12 cm long. Cut the two sides of the base into a 45-degree slope. Cut longitudinally at about 1/3 on one side of the rootstock, 2 to 3 cm deep. Insert the scion into the incision, align the cambium, bind it tightly with a plastic bag, and bury it in the soil.

2. Cuttings: one-year-old branches are selected before spring germination and cut into 5 to 10 cm long. Cut off the lower leaves, leave 2 to 3 leaves in the upper part, and insert them in the river sand or loess seedbed with a row spacing of 3 × 20 cm. Irrigation shade in time after insertion, keep the temperature from 20 ℃ to 25 ℃, relative humidity 85% to 90% can take root for 2 months.

3. Striping: there are two kinds of low pressure and high pressure. Under low pressure, the mother plant of sweet-scented osmanthus should be selected. From spring to early summer, the branches of the lower 1-2-year-old flexible parts should be cut or peeled around with a sharp knife, which is as deep as xylem. Press it into a groove 3 to 5 cm deep and fix it with wood strips. In the high-pressure method, 1-2-year-old branches were selected from the mother tree in spring. after girdling, the wound was wrapped in a culture medium and fastened in a plastic bag. In the process of culture, the substrate was kept moist all the time, and the roots were cut off from the mother plant in autumn.

How to raise potted osmanthus?

1. Soil: sweet-scented osmanthus likes to grow in slightly acidic soil and can be cultivated with a mixture of peat, garden soil, sand and river sand with a ph of 5.5 to 6.5. Cultivated soil before using potassium permanganate solution for soil disinfection, the best choice of tiles is the best, water permeability is very good. The substrate of basin soil is effective, generally changing the basin once in 1-2 years, and changing it in early spring, which is more conducive to the growth of plants.

2. Watering: sweet-scented osmanthus likes high temperature and dry environment, so it is necessary to master the watering situation. It is most appropriate to water more in the summer to keep the soil moist at about 50%. And when it is overcast and rainy and sprouting, ah, less watering, anyway, the basin soil is stagnant water, so as not to cause rotten roots. Shade treatment in summer, the temperature can not be higher than 35 degrees Celsius, and spraying water around the flowerpot can achieve the cooling effect.

3. Fertilization: sweet-scented osmanthus in the four seasons likes organic fertilizer when it is hungry. It can be fertilized once a week when sweet-scented osmanthus sprouts, using rotten thin liquid or pig manure. Organic compound fertilizer is used in July and phosphate fertilizer is applied in September to make the four seasons sweet-scented osmanthus grow more luxuriantly and thus improve the ornamental value.

4. Temperature: four Seasons Cinnamomum can be cultivated in the south of the Yellow River basin for overwintering. Potted plants should be moved indoors in winter and placed in a place with sufficient sunshine to fully accept direct sunlight. The room temperature should be kept above 5 ℃, but not more than 10 ℃. After sprouting in April of the following year, it was moved to the outdoors, first maintained in the leeward to the sun, and then gradually moved to a ventilated sunny or semi-overcast environment after stable growth, and then carried out normal management.

5. Pruning: sweet-scented osmanthus can be pruned in spring and autumn, after blooming in autumn for the first time, and then pruning off the longer and too dense branches of the plant to leave sturdy short branches. The second pruning is before sprouting in early spring, pruning off dead, weak and diseased branches so that it can sprout better. Generally meet the requirements of short and strong, thick trunk and symmetrical branches and leaves.

Matters needing attention of four Seasons Gui

1. Four seasons osmanthus should be fully fertilized, especially the lack of phosphorus will affect the branches of sweet-scented osmanthus trees, and the flowers are less or less fragrant. The root system of four seasons cinnamon is well developed, and the adult four seasons cinnamon will shoot every spring and autumn, so we should pay attention to pruning, keep the plant shape beautiful, balance the physiological nutrition of four seasons cinnamon and promote the growth of flower buds.

2. When watering the four seasons cinnamon, we should pay attention to less watering before the new shoots grow, less watering in cloudy and rainy days, more watering in the dry weather in summer and autumn, and mastering the amount of watering when blooming in autumn to keep the basin water moist, too wet will cause falling flowers.

3. There are many diseases and pests in sweet-scented osmanthus in the four seasons, such as brown spot, blight, anthracnose, red spider and mulberry scale, etc., which can be eliminated or removed manually.
