Potati seeds are generally harvested from September to November. It needs to be washed with water after harvesting. Wash off the outer skin of the seeds but do not damage them. Then filter out impurities and place the seeds in an incubator. Spray a certain amount of post-ripening solution to maintain a high humidity. After that, they were irradiated with ultraviolet light for 20 minutes, and then soaked in water for 4 days. Finally, take them out to dry in the shade, put them in wet sand, and wait for germination.

1. Seed collection and cleaning

1. Seed collection and cleaning

The seeds of Polygonatum japonica generally mature from September to November. At this time, they are harvested and soaked in water. Scrubbing to remove the outer skin of the seeds will help increase germination rates. Do not break the seeds when cleaning, then filter out the outer skin and impurities and remove the seeds.

2. After-ripening

Place the Polygonatum seeds in an incubator and spray the post-ripening solution. The humidity inside the incubator should be high and not too dry. Then irradiate it with ultraviolet light for 20 minutes, take it out and let it sit for 1 hour. Soak it in water at 20°C and take it out after 4 days.

3. After shade drying

Ripe seeds cannot be planted in the sun, otherwise they will easily lose moisture and reduce their germination rate. You need to put it in a cool place and wait for it to dry. It can also be dried in a freeze dryer to speed up the germination of seeds.

4. Germination in Shazang

Bury the treated seeds in wet sand and leave them for 100-150 days before taking them out. The germination rate of the seeds at this time can reach 80%, and the germination time can be shortened, and they can grow in about a month.
