摘要： 摘要：本文在土培条件下，以非灭菌土壤为生长基质，研究了不同施N水平下接种AM真菌摩西球囊霉（Glomus mosseae）对丹参（Salvia miltiorrhiza Bge.）幼苗化学成分的影响。结果表明，不同施N水平对AM真菌接种效果有明显影响。接种AM真菌提高了丹参根系菌根侵染率，叶片可溶性糖、可溶性蛋白和植株全氮含量；增加了地下部及全株丹参酮含量。说明接种AM真菌有利于丹参植株生长，能够提高丹参幼苗化学成分含量。在施N量为0.085~0.17g N/kg土时，接种AM真菌效果最好。

Abstract: Abstract: The effects of AM fungi on the chemical components of Salvia miltiorrhiza Bge.under different N-applied levels in the pot culture were studied. The results showed that AM fungi had significant influences on the growth of Salvia miltiorrhiza Bge. under different N-applied levels. Mycorrhizal infecting rate, soluble sugar, soluble protein,and N content of host plant were promoted by inoculation AM fungi under N-applied levels. Meanwhile, AM fungi had positive effects on the content of tanshinone of root content and whloe-plant. AM fungal inoculation is conducive to the growth of Salvia miltiorrhiza Bge. and raise seedlings of chemical ingredients. The inoculation effect of AM fungi was the best under 0.085~0.17g N/kg soil.
