1. Seed propagation:In the Sichuan region, sow in September to October. Before sowing, prepare the soil well and open furrows 1.3 m deep. On the furrows, open crosswise trenches at a row spacing of 30 cm and a depth of 4-6 cm, with a sowing width of about 10 cm, keeping the bottom flat and the soil loose. The seeds need to be mixed into plant ash mixed with human and livestock manure water to form seed ash. Use 5-6 liang of seed per mu. When sowing, first apply human manure water in the trench, then evenly scatter the seed ash into it.
2. Division propagation:After the summer harvest, dig out the old clumps, select the well-grown ones, divide them into small clumps, and plant them at a row spacing of 30 cm and a plant spacing of 7-10 cm, then pour on livestock manure water.
3. Field management:For those propagated from seed, when the seedlings are 1 cm tall, water once with light human and livestock manure water to promote seedling growth. When the seedlings are 3-4 cm tall, thin them and fill in gaps. Keep one seedling every 3-4 cm; when filling in gaps, transplant with soil. After thinning, cultivate and weed once, and apply topdressing at the same time. For those propagated by division, when new shoots emerge after planting, cultivate and weed and apply topdressing once. After that, only weed and loosen the soil as needed. After the September harvest and in November, apply topdressing once each time for overwintering.
