黄土高原干旱山区不同地形农田对党参生长发育的影响

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

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 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.
