The choice of seedling site: the heavy building seed bed should choose the open land or slope land under the forest with high topography, good drainage, soil rich in organic matter and good shade (20%), and the dry land should build 3-layer shade net. Choose a sunny day, ploughing the fields and leveling the beds. Border width 120 cm, ditch width 30 cm, ditch depth 25 cm, ditch to smooth, conducive to drainage. Treatment of Rhizoma thunbergii seeds: Rhizoma thunbergii seeds should be full, mature, free from disease, mildew and damage, mix them with clean fine sand with 2 ∶ 1, rub off the outer seed coat, wash it, soak the seeds with 500x carbendazim for 1 hour, bury them in wet sand, after 20 ℃ treatment for 4 months, sow the seeds after rooting, pay attention to moisturizing during this period. The sowing method of Rhizoma thunbergii seeds: the treated seeds can be sown on demand and strip sowing, or they can also be spread. When sown in humus soil and fine sand (2 ∶ 1), the seeds should be covered with 1.5 cm thin soil layer and covered with loose hairs to preserve moisture, which is not only conducive to seedling emergence, but also conducive to shelling cotyledons to ensure seedling emergence rate. During this period, it is necessary to keep the seedbed moist and shady, and avoid soil hardening, dryness and excessive sunshine. The seedlings usually emerge in 3-4 months. Heavy building cutting breeding method: in winter, the disease-free, normal shape of the heavy building underground stem is cut according to two nodes (about 2 cm), and the wound is treated with plant ash. The cut pieces with top buds can be planted in the field directly. The cutting pieces without terminal buds were planted at a row spacing of 7 × 7 cm. After planting, they were covered with broken grass or humus soil to keep moisture (the soil moisture was 65%), and the shady environment was maintained. The transplanting method of Rhizoma thunbergii: the seed seedlings were transplanted 3 years after emergence, and the row spacing was 10 × 20 cm. The cuttings with apical buds were planted according to the row spacing of 10 × 20 cm, and those without terminal buds were dug out when the adventitious buds had been formed in the following winter, and planted according to the row spacing of 20 × 30 cm. After transplanting, cover with loose hair or humus to moisturize and maintain a shady environment. The transplanting time should be in winter, after the seedling of the aboveground stem, when the rhizome is dormant, and pay attention to protect the terminal bud and fibrous root from damage in the process of transplanting.
