Preparation of Osmanthus fragrans seeds before sowing

Seed inspection

Seed inspection is to remove empty shells and deteriorated seeds. Some plump seeds can be cut randomly with a knife to observe whether the seeds are fresh and energetic. Generally, the kernel of good seeds is milky white

Seed disinfection

After the seeds are washed with clean water, soak them in 1% bleaching powder or 0.5% potassium permanganate solution for disinfection for about 15-20 minutes, then rinse them with clean water and dry them, or soak them in 0.5% formalin solution for about a quarter of an hour, pour out the solution, seal and seed them for about 30 minutes, and finally rinse them with clean water and dry them

Germination of Osmanthus fragrans seeds

In order to promote the rapid germination of seeds, the sterilized seeds can be soaked in warm water at about 50 ℃ for about 4 hours. After taking out the seeds, put them into the basket, covered with straw or wet cloth, and put them at the temperature of 18-24 ℃. When more than half of the seeds have cracked bell shells or slightly exposed radicle, sowing can be carried out. In the process of germination, the seeds need to be turned frequently to keep the temperature and humidity of the upper and lower layers consistent, so as to make the germination neat
