Taking the seedling of edible Acanthopanax sessiliflorum as material,the effect of different pH on growth and development and root activity of Acanthopanax sessiliflorus were studied.The results showed that the edible Acanthopanax sessiliflorum could be survived under slight alkaline soil in Ningxia Yellow river irrigation area.While pH 6.87,partial acid,the plants were the highest,and the plants had the most leaf numbers,the biggest accumulation biomass and the strongest root activity.The plants grew better in acid soil than slight alkaline with relating to its genetic factors.While pH was 9,5% plants were still survival,transplanted to pH 8.76 soil,it grew very well.
