The seeds were mixed with plant ash, then sowed, covered with soil and covered with wheat stalk, and then watered with 1: 1.5 jin of seeds per mu. Autumn sowing before freezing, others are the same as spring sowing.

The seeds were evenly scattered on the border surface and covered with soil. During strip sowing, the seeds were planted in trenches according to the row spacing of 10 cm, and then covered with soil and grass and watered.
Transplanting ② seedlings: Bupleurum emerged about 10 days after sowing. When the root diameter was 2mm and the root length was 5cm, the seedlings were transplanted.
