| 摘 要： | 将双色蜡蘑(Laccaria bicolor)的3个株系(Lb 270、Lb S238A和Lb S238N)分别与马尾松种子拌匀,培养在酸性土壤中,以检测根际土壤无机磷和活性铝含量,并分析外生菌根对磷有效性和铝活性的作用。结果发现,与非菌根苗相比,接种双色蜡蘑显著促进马尾松幼苗生长和对磷、铝的吸收,而对根际土壤无机磷和活性铝含量的影响因菌株而异:Lb 270和Lb S238N显著降低pH、有效磷、全铝、交换态铝含量,提高羟基态铝含量,且Lb 270还显著降低铁磷和钙磷含量;Lb S238A显著提高pH、有效磷含量,减少铝磷、全铝、活性铝、交换态铝和腐殖酸铝含量。即接种双色蜡蘑提高了磷的生物有效性,且Lb 270和Lb S238N增加、Lb S238A减少铝的活性。因此,接种供试双色蜡蘑都能提高马尾松的抗铝性,主要在于其增加磷的生物有效性,而是否降低铝的活性取决于菌株特性。
