Osmanthus fragrans is an evergreen aromatic tree species unique to China. It is a city flower of Hangzhou and has important economic value in landscaping and spice production. Cuttage is an important method for the reproduction of sweet-scented osmanthus. It is the season of sweet-scented osmanthus cutting and cutting. Now the twig cutting techniques of sweet-scented osmanthus are briefly introduced as follows. First of all, the cutting propagation site should be selected to shelter from the sun, close to the water source, convenient drainage and irrigation, and the soil is slightly acidic sandy loam. There are many perennial weeds and no nursery can be used where there are serious underground pests. The plot selected for cutting should be deep-turned in the summer and autumn of the first year. After the weathering, the site will be nursed. In the previous month, dipterex can be sprayed 800-1000 times to eliminate nematodes. Half a month ago, a 1:100-fold formalin solution was used to disinfect the soil bacteria and then covered with a plastic film. After 10 days of boring, the residue was released to prevent injury. 2 to 3 days before the plug with water soaked, dry after the flat bed for later use. In order to avoid high-temperature burns and maintain a cool, moist environment, double shade shades are often used. Scaffolding materials may be steel or bamboo. The high shade shed is 2 meters high and the top curtain is covered with reed curtains. There is a low shade shed, 0.7 meters high. It also needs a reed curtain. The mother trees that are to collect the cuttings should be pruned after flowering in the fall of the previous year, deep-dipping and fertilizing. After germination, each mother branch only left 1-2 buds at the tip of the center to remove excessive clusters of branches and concentrate nutrients to ensure that the new shoots are robust. The cuttings should be collected from a robust mother tree with the characteristics of the species. Branches in the upper part of the canopy and in well-lit areas should be sturdier, which is beneficial to rooting. The shades, slender branches, diseased shoots, and legumes of the inner part of the tree canopy should not be used. . In principle, it should be collected from the tree that has already been flowered. Cutting length 8-l0cm, thickness 3-5mm, retain 2 leaves. Before plugging in, the base of looppm naphthalene acetic acid soaking inserts was cut for several hours or quickly soaked with a 300-500 ppm naphthalene acetic acid solution for a few seconds. Treatment with rooting powder abt is better. Insert 1/2 - 2/3 of the cuttings into the soil, then compaction by hand, pouring enough water to ensure that the soil is in close contact with the cuttings. The cutting density is 10-12 cm, the spacing of plants is 3-5 cm, and about 100,000 can be inserted per mu. Post-cut management is very important. The temperature in the shade should be maintained at 20-25°C and relative humidity between 89-90%. Avoid direct sunlight for 1-2 months after insertion. The double-layer lu screens have a light transmittance of less than 30%. During the cutting period, two covers are opened, namely the cover in the morning and the cover in the evening. High-temperature exposure, sunny cover, rainy days exposing. High-temperature and dry weather should spray 4 to 5 times of water every day to keep the shed moist. In case of soil moisture in the seedbed bed, the number of watering can be reduced, and the time for the morning shed can be delayed by one hour in the morning, and the shed can be left for one hour in the afternoon to evaporate too much water. After 2 months of insertion, the base of the cuttings formed a bruise and the new roots grew. In the year of sweet-scented osmanthus cultivars, there were few hair roots, few growth, and poor resistance to seedlings. From October onwards, they could gradually increase the duration of light and reduce the number of watering operations. They began to “refining†and paid attention to cold protection throughout the winter. With effective management, the survival rate of Osmanthus fragrans tender cuttings can reach 90-95%.
