Planting method of high-quality and high-yield root-bark of peony

Abstract

The invention discloses a planting method of high-quality and high-yield root-bark of peony, comprising the steps of land selection and preparation, sowing, seedling culture, transplanting, field management, harvesting, processing, and the like. The planting method is characterized in that the yield and the quality of the root-bark of peony are improved by adopting measures of controlling the growth of an underground part and spraying foliar fertilizer. According to the planting method disclosed by the invention, by adopting a series of measures of culturing seedlings, transplanting, controlling nutrient growth, spraying foliar fertilizer, and the like, the quality of the root-bark of peony is increased, the yield is increased simultaneously and is improved by 20 percent compared with that obtained by the traditional planting method; the content of effective components is increased by over 10 percent; and the root-bark of peony has thick flesh, pink white cross section, strong aroma and export standard strip selecting rate of over 80 percent. Meanwhile, the contents of pesticide residue and heavy metal are reduced and the exported standard of medicinal materials is reached.

Problems solved by technology

[0003] At present, the domestic production of Chinese herbal medicines is mainly based on small-scale extensive planting mode with farmers as the main production and management. Pesticide residues and heavy metal content exceed the standard, and the quality is unstable. It is difficult to meet the quality control standards of Chinese herbal medicines, which seriously affects the development of Chinese herbal medicines.
