First of all, sweet-scented osmanthus varieties can be selected according to their preferences and resource conditions, and then 2-3-year-old branches of good quality and pure quality can be selected from the selected sweet-scented osmanthus trees. 2-3-year-old branches with strong growth, full development, no disease and insect harm, high ornamental value or economic value are used as scions.

Grafting method of Osmanthus fragrans

Abdominal connection and abutment are generally used.

1. Ventral grafting: ventral grafting means that the rootstock is trimmed before it is connected. Cut off all the pieces at 6ml / 7cm from the surface of the soil, and cut obliquely near the rhizome so as not to hurt the pulp. The scion uses 2 Mel 3 branches (without leaves) and is about 10 cm long. It is suitable for the scion with 2 Mel 3 nodes. Then the ear interface is cut into an unequal wedge and inserted into the cutting of the rootstock to make it close. Bind the soil with plastic or hemp skin to the top of the scion.

two。 Lean on: to pick up is to first put the rootstock in a basin to feed. During the Meiyu period from June to July, two-year-old sweet-scented osmanthus seedlings with similar thickness to rootstocks were grafted in pots, and cut off in front of "White Dew" after survival. That is, the new plant can blossom in the same year.

3. After the grafting survived, when the new graft was slightly as long as 10-15 cm, cut off all the remaining branches and tillers of the rootstock. As the anvil is easy to sprout adventitious buds, it should be peeled off at any time. Drought resistance, topdressing and weeding were carried out from June to August. Potted seedlings. When the new shoot reaches about 15%, coring should be carried out to promote the growth of lateral branches and form a shrub.

4. After the beginning of spring, fertilization begins when the temperature rises above 15 ℃ in the evening, when the branches begin to grow and need fertilizer. If you are using compound fertilizer, apply 4 grams at a time (about one lid of a small mineral water bottle), make four small holes around the basin soil or plant, put the compound fertilizer down evenly, cover it with soil (change position the next time you drill the hole), and apply fertilizer every 15 days until the temperature drops below 8 ℃ in the autumn evening. If you are using organic fertilizer such as cake fertilizer, the amount used each time is 1 bowl of rice bowl and 3 bowls of organic fertilizer (no water). If you bought the packaged fertilizer from a florist, just follow the packing instructions, and if there is no packing instructions, ask clearly. When you see buds growing, stop fertilizing, for excess nutrition will drop buds (except osmanthus).
