Choose the high and dry terrain. If the drainage is good, the general land can be planted. Base fertilizer is applied before soil preparation, because Yuanzhi perennial herbs, base fertilizer must be fully applied, commonly used ring manure or compost 2500 kg per mu, 50 kg calcium superphosphate ploughing and raking flat, and flat strip sowing is mostly used in the north.

Polygala root was used as medicine, and it was harvested 2-3 years after sowing, so that the yield was high and the quality was good. Harvest in autumn after the seedlings withered or before sprouting in spring, dig out the roots first, be careful not to hurt the root bark. After removing the fibrous root and washing the soil, first put it on the cement floor and expose it for 3-4 days. When it is semi-dry, put the Yuanzhi stick into a bag and fill it with compaction.
