The invention discloses a technology for planting
codonopsis pilosula in barren soil in southern China. The technology comprises the following steps that land selection and preparation are conducted, specifically, wet sandy soil or sand soil with
irrigation conditions or soil rich in
humus or a downsun shady slope is selected as a
seedling field; a
reproduction method is determined, specifically,
seed treatment,
seedling and direct seeding as well as
transplantation are conducted; field management is conducted, specifically, sun shades are removed, and
thinning,
tillage and weeding, topdressing, drainage and
irrigation as well as propping are conducted; pest and
disease damage and prevention and treatment thereof are determined, specifically, a cultivator should pay attention to prevention and treatment of
root rot, the
rust disease and
downy mildew among the diseases as well as pay attention to prevention and treatment of grubs, cutworms, mole crickets, red spiders and aphids among insets damage; the seed reserving technology is conducted, specifically, two-year-old plants have more flowers and seeds and are high in yield, good in quality and suitable for seed reserving; harvesting and
processing are conducted, specifically, harvesting is conducted when the aboveground parts of the plants are withered and become yellow in autumn; and storage is conducted, specifically, the aboveground parts are stored in ventilated dry places, and moth proofing,
