Reproduction points of sweet-scented osmanthus
Osmanthus fragrans tree cutting propagation, simple operation, more suitable for family use. The key to cutting propagation is the choice of cuttings, which is directly related to the survival rate of sweet-scented osmanthus trees. The branches of the thick and semi-ripe branches can be cut into the cuttings of the twigs. Cutted ripe branches can also be cut into hard-cut cuttings. When selecting cuttings, avoid using long branches, slender branches, inner lychees and diseased branches. The length of the cuttings is 8 to 12 cm, the young shoots are cut off, and the leaves are left at the top. With the cut and insert, the depth of the inserted soil is 2/5 of the total length, and then the soil is compacted and poured with water for one time. Sweet-scented osmanthus trees prefer a cool environment with high air humidity, especially the cuttings that have not yet taken root. They should not be too dry, and they should not be exposed to the sun. Pay attention to the sunshade within 1 month after cutting. It is best to set up a double-layer awning. The height of the high shed is about 2 meters. The low shed is 60 to 70 cm high. The sunshade in the high shed should also be shaded. When the weather is dry, spray the sprayer 1 or 2 times a day. When the new root is 3 to 4 cm long, it can be transplanted. 1 to 2 weeks before transplanting, the sunshade mat or straw curtain should be removed to allow the young seedlings to exercise.
Osmanthus sinensis batting is divided into two types: aerial beading and ground beading.
First, aerial layering can be carried out all year round, but it is better before spring germination. Aerial layering is more suitable for family potting. Usually, before and after the Ching Ming period, 2 to 3 years old branches are selected from the strong breeds of the mother plant for ring stripping. The width of the incision is about 2 cm. The bamboo tube is taken and opened, and a layer of sandy moist culture soil is laid inside. The strips were peeled all over, wrapped in plastic cloth, and then tied with a belt. The wound healed after 1 month, and new roots were born in the incision cortex 3 months later. In the spring of October or the next spring, when the new root is 3 to 5 cm long, the mother plant can be cut off.
Second, the ground bead is also known as the Fuzhi bead or ordinary bead. This method should be carried out in April to June or August to September (temperature is between 25 ° C and 30 ° C). Cut the skin 1 to 2 cm long on the branches near the roots, and bend it to the ground. Pile 7-8 cm thick soil on the wound branches, compact, and keep watering to keep it moist for about 3 months. root. In the spring of the next year, it was cut with the mother plant and planted a new plant. In the case of potted plants, the cut branches can be pressed into another potting soil and fixed, and then transplanted after rooting.
