Osmanthus tree breeding is generally cuttings. In the breeding process, it is necessary to pay attention to some relevant details, such as the collection and processing of seeds, storage, and the time of sowing and requirements for the following year. Here are some specific issues:
1. Seed collection and treatment: Generally, from May to June, black purple seeds with full fruits are collected from the osmanthus tree or on the ground. Post-harvest treatment: The seeds are mixed with sand to remove the seed coat and the water is used to remove the empty seed shell floating on it.
2. The seeds are stored and the seeds of the seed coat are removed after a long time of sand burying, until they are completely mature and germinate; the seeds can be buried in wet sand, stored in a water tank, and sealed with glass pieces to moisturize. During the storage process, sand should be moisturized. The amount of water needed to maintain one-tenth of the amount of sand in the reservoir should be maintained. In the middle and later stages, half of the water should be guaranteed.
3, sowing time and requirements: in the following year in March, when the seed buds can be cultivated seedlings, sowing seeds need to cover the grass to maintain shade, then osmanthus saplings can grow to more than 16 cm. After two years of cultivation, the saplings are transplanted in the spring of the following year and the flowering period is within ten years.
