摘要

[Objectives] This study was conducted to further explore the yield increasing potential of Codonopsis pilosula, and to seek seedlings suitable for efficient production of C. pilosula. [Methods] The effects of C. pilosula seedlings of different sizes on root yield and commercial quality under different cultivation densities were studied. [Results] The fourth-grade seedlings had the least input, the highest yield of 6 948 kg/hm~2, the largest output-to-input ratio at 18.3, the highest root weight proportion of the second-grade product at 58.1%, and the lowest root weight proportion of the first-grade product at 17.6%. Considering the yield, quality and economic benefits comprehensively, the treatment of the fourth-grade seedlings(seedling diameter≤4 mm) is the best choice, and the suitable plant spacing is 8 cm×22 cm. [Conclusions] The study provided a reference basis for the cost saving and efficiency improvement of C. pilosula production.
