摘　　要：以短梗五加实生苗为试材,研究了不同pH值的土壤环境对短梗五加生长发育和根系活力的影响。结果表明:短梗五加在宁夏河套灌区微碱性土壤环境中是可以存活的。其中在pH为6.87的偏酸至中性环境中,短梗五加的茎高最高、叶片数最多、生物量的积累最大且根系活力也最佳。偏酸环境生长的短梗五加相对比偏碱环境生长的短梗五加长势好些;但在pH为9时,仍有5%的植株能够存活,将其移栽到温室pH为8.76的环境中,则生长状况良好。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.
