[Effects of Different Terrain Farmland on Codonopsis pilosula Growth in Loess Plateau Dry Areas].

Objective: To study the effects of different terrain farmland on Codonopsis pilosula growth in arid regions, and then to provide basis for choosing appropriate terrain for Codonopsis pilosula cultivation in the northwest region.

Methods: Based on the observation of field production,plot cultivation experiment was designed to observe and record the effects of different terrain farmland on Codonopsis pilosula growth period and yeild, and to analyze the terrain effects on Codonopsis pilosula production comprehensively.

Results: There were no significant differences between field production and plot cultivation experiment. The results both showed that different terrain farmland significantly affected Codonopsis pilosula growth. Shade slope was the best, then sunny slope followed, terrace and ridge were not suitable for Codonopsis pilosula growth.

Conclusion: The terrain is a critical part in Codonopsis pilosula production. To ensure the stability of Codonopsis pilosula production and economic benefits, it is best to choose the shade slope for cultivation.
