1. Seed propagation: choose moist, fertile dark brown soil on a shady slope, stratify to sprout in autumn and spring, and drill-sow; seeds with the aril removed undergo wet sand stratification from November to April of the 3rd year, a total of 19 months, until the embryo turns yellow and the seed begins to germinate and crack; rub off the aril, soak in 100 ug/g of 920 for 1 hour, and after half a year of wet sand stratification they can germinate. 2. Cutting propagation: mix garden soil, sand and charcoal ash, build a shade shed with 30 percent light transmittance, and cover with plastic film to retain moisture. First cut 1-year-old branches into 10-15 cm cuttings; the cuttings are first treated with 10

2. Cutting propagation: mix garden soil, sand and charcoal ash, build a shade shed with 30 percent light transmittance, and cover with plastic film to retain moisture. First cut 1-year-old branches into 10-15 cm cuttings; the cuttings are first disinfected for 12 hours with a 1000-fold 50 formalin solution or similar, treated with 500 ppm ATP rooting powder, and inserted into the seedbed; after 70 days the rooting rate is 83; treat cuttings with 100 ppm indoleacetic acid and insert them in vermiculite to root in 45 days. From May to June, soak in 100 ppm IAA or 100 ppm NAA for 3 hours, insert into the seedbed at a row spacing of 6 x 10 cm, water, and retain moisture with plastic film for 50 days; in the 3rd year seedlings can be taken, divided and planted at a row spacing of 100 cm, and leaves can be harvested in 3-5 years.

3. Tissue culture: induce roots in a 2-5 mg/L NAA + 0.2 mg/L KtB5 medium; culture embryoids in a B5 medium with 5 mg/L zip + 5 mg IBA (16 h light). Culture immature or mature embryos with Wohite and Ms media, with a germination rate of 70; with 4 degrees C low-temperature treatment, the germination rate is 80; adding 0.4 ppm MgSO4 promotes root and embryo growth; culture embryos on MS or B5 medium with MS + GA3kt 10 mg/L to mature them, then transfer to N6 or whit medium containing 1 percent sucrose to induce complete plantlets.
