How do sweet-scented osmanthus reproduce?

1. Twig cuttings

The excellent mother plants with good varieties, exuberant growth and no diseases and insect pests were selected to pick ears, and the semi-lignified shoots in the upper part of the crown were cut as cuttings. The cuttings should be cut into 2-3cm, with 1-2 leaves at the top. The upper end of the ear is cut into a flat mouth, the base is cut into a slope, and the slope should be smooth to facilitate cutting and healing and rooting. The panicle strips were disinfected by soaking 10min with 0.1% thiophanate methyl or carbendazim. Then soak the base in 50mg naphthalene acetic acid or ABT rooting powder No. 1 solution of 100mg, take out the cuttage after 1 hour, or soak 10min with 200mg naphthalene acetic acid before cutting.

two。 High-altitude pressing strip

The high-altitude striping method is mostly carried out before sprouting in spring, can also be carried out during the summer growth period, and has a good effect in the plum rain season. In high pressure propagation, the rooting time is generally long, about 3 to 4 months. After cutting off the mother plant, it must be placed in a shady place and maintained for a period of time before it can be transplanted.

3. Rootstock grafting

The main results are as follows: (1) Bud grafting and branch grafting are usually carried out in spring and autumn, and cutting and splitting are often used.

(2) bonding: suitable for the peak growing season, usually between June and July. It can heal about 30 days after grafting, but it is best to separate from the mother after the buds are enriched.

No matter what method is used to breed sweet-scented osmanthus, it is best to do it in the case of experience.
