中文摘要：

以非灭菌土为生长基质,采用盆栽实验研究了不同施磷水平下接种摩西球囊霉（Glomus mosseae）对白术生长和生理特征的影响。结果表明,摩西球囊霉能够与白术形成良好的共生关系,在0-0.4 g P/kg土水平时,接种摩西球囊霉可显著提高白术根系菌根侵染率,并以0.05 g P/kg土水平时侵染率最大,磷水平继续提高则菌根侵染率反而降低;接种摩西球囊霉对白术地下部的影响效果尤为明显,其根长、株高、地下部干重均在0.1 g P/kg水平时达到最大值;适量施磷条件下,接种摩西球囊霉可显著提高植株可溶性糖和可溶性蛋白含量,有效增强保护酶SOD、POD和CAT活性。研究发现,当施磷量为0.05-0.1 g/kg土时,摩西球囊霉接种效果最佳,对白术的生长最为有利。

英文摘要：

The effects of Glomus mosseae（GM） on growth and physiological characters of Atractylodes macrocephala Koidz.under different P-applied levels in the pot culture were studied.The results showed that GM and Atractylodes macrocephala had symbiosed efficiently.Inoculating GM significantly increased mycorrhizal infection rate at 0-0.4 g P/kg soil level.The infection rate reached the highest level at 0.05 g P/kg soil,but the infection rate reduced with the increase of phosphorus levels.Effect of inoculating was obvious to underground part.At 0.1 g P/kg soil level,the root was the longest,the adult plant was the highest and the dry weight of underground part was the most.It was found that GM could increase the content of soluble sugar and soluble protein,improve activity of protective enzymes under suitable phosphorus level.In a word,inoculation effect of GM was the best under 0.05-0.1 g P/kg soil.
