目的:研究干旱地区不同地形对党参生长发育的影响,为西北地区栽培党参选择适宜的地形提供依据。方法:在观察大田生产基础上,设置小区栽培试验,观察记录在干旱条件下不同地形的农田对党参各生长发育期和产量的影响,综合分析地形对党参生产的影响。结果:小区试验结果和大田生产实际情况变化趋势一致,在干旱地区不同地形对党参生长发育的影响有着显著的差异,背阴坡地生产党参效果最佳,向阳坡次之,而梯田和山梁最不适宜生产党参。结论:在干旱地区选地是生产党参的关键环节,为保证党参产量和经济效益的稳定,栽培党参宜选择阴坡地。
Objective: To study the effects of different topography on the growth and development of Codonopsis pilosula in arid area, and to provide a basis for selecting the appropriate topography for Codonopsis cultivation in Northwest China. Methods: Based on the observation of field production, we set up a plot cultivation experiment to observe and record the effects of different types of farmland on the growth and yield of Codonopsis pilosula under drought conditions and comprehensively analyze the impact of topography on the production of Codonopsis pilosula. Results: The result of plot test showed the same trend with the field actual situation. The effect of different topography on the growth and development of Codonopsis pilosula in arid area was significantly different. Codonopsis sp. Produced the best effect on shady slope, followed by sunny slope, while terrace and mountain beam were the most unsuitable Dangshen production. Conclusion: The selection of arid areas is the key link in the production of Codonopsis. In order to ensure the yield of Codonopsis and the stability of economic benefits, Codonopsis should be chosen to cultivate shady slopes.
