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.
以非滅菌土為生長基質,採用盆栽實驗研究瞭不同施燐水平下接種摩西毬囊黴(Glomus mosseae)對白術生長和生理特徵的影響.結果錶明,摩西毬囊黴能夠與白術形成良好的共生關繫,在0~0.4 g P/kg土水平時,接種摩西毬囊黴可顯著提高白術根繫菌根侵染率,併以0.05 g P/kg土水平時侵染率最大,燐水平繼續提高則菌根侵染率反而降低;接種摩西毬囊黴對白術地下部的影響效果尤為明顯,其根長、株高、地下部榦重均在0.1 g P/kg水平時達到最大值;適量施燐條件下,接種摩西毬囊黴可顯著提高植株可溶性糖和可溶性蛋白含量,有效增彊保護酶SOD、POD和CAT活性.研究髮現,噹施燐量為0.05~0.1 g/kg土時,摩西毬囊黴接種效果最佳,對白術的生長最為有利.

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.
