Spray "medicine root Daling" before angelica flowering, young fruit period, and fruit expansion period. It has been proved by practice that by spraying the medicinal material Gendaling, it can promote photosynthesis products on the leaves, improve the nutrient conversion rate and soil loosening ability, make the rhizomes expand rapidly, and greatly increase the content of effective substances.

If there is too much rain, it is necessary to drain the ditch in time, especially in the late growth period. Water should not accumulate in the field, otherwise it will easily cause root rot. In order to enhance the resistance of Angelica sinensis against the adverse external environment, spraying plant protection agent Xin Gaoli film can resist drought, prevent waterlogging, disinfect and prevent diseases, effectively prevent water transpiration, improve light and utilization efficiency, and strengthen seedlings and fruits. effect.
