Osmanthus rapid propagation
Osmanthus fragrans is one of China's ten traditional famous flowers. It is a treasure of scented plants. It is widely used in ornamental, greenery and aromatized environments, and has broad development prospects. At present, osmanthus production efficiency is promising. Propagation. At the end of March and early April, around the female parent, depending on the number of branches that can be pressed (usually 4-5 branches can be pressed per mother), dig a small depth and width of 20 centimeters along the direction in which the branches naturally stretch. Ditch, and then the homeopathic pressure into the ditch, and fill the groove with fertilizer to fill the solid, pouring enough water and then press the roots of the site into a bread-like shape can be cultivated. High air pressure strips. During September-October, 1 bamboo tree branch was broken into 2 pieces (or plastic bags), filled with wet soil, covered with strong shoots of fine osmanthus varieties, and supported by brackets, often adding water to maintain the cylinder ( Bag) The inner soil is moist, and after 1 month, a new root is produced. In the spring of the following year, when transplanted and transplanted to the ground, it becomes a robust osmanthus tree that can bloom in 3 years. Nursery breeding. In May of each year, ripening stone fruits from osmanthus trees are picked, removed from the shell, and dried in damp sand. It was sown in the spring of early spring and planted in pre-warm nursery beds until the warm weather in March. Generally about 15 cm in height a year, good care, 2-3 years can grow up to 1 meter, you can plant out of the garden. Grafting and breeding. Select one-year-old robust lateral branches with a population of about 20 years old, cut two buds, and graft them onto the stocks of Ligustrum lucidum. It can bloom after 4 years, but the main trunk is not straight and is not suitable for afforestation. Branch propagation. The cutting season is selected in February when the sap will flow. The slotting machine uses 30% mature soil and 70% fine river sand. One month prior to cutting, the sprayer was sprayed with 800-1000 times of dipterex to eliminate nematodes. 10-15 days before insertion, then disinfect with lime water. Three days before the insertion, the slotting machine is rinsed with clean water. After drying, the bed surface is leveled to complete the preparation work. Select the strong, year-round, robust lateral branches with good cultivar, robust plants, and ages of 20-25 years, and cut about 20 cm of cuttings. Cut 2-3 slices of the top half of the cuttings and remove the remaining leaves. One end of the cutting was cut into a horseshoe shape and the base was treated with 10 mg/kg naphthyridine for 10 hours. The cuttings were 5 cm and 10 cm apart, inserted slightly obliquely, and the insertion depth was 2/3 of the cutting length. After compaction, press the bed soil, cover the grass between rows, drench the water once, and put a shadow stand. When the new branch to be sent is longer than 6 cm, it can be transplanted into the nursery. During the period of plugging, pay attention to moisturizing, shading, and prevention of accumulation of water, 80,000 per acre seedbeds can be cut, suitable for large-scale breeding. With good care, the survival rate can reach more than 90%, and generally it can bloom after 4-5 years after transplantation.
