研究了美味牛肝菌(Boletus edulis)、华美牛肝菌(Boletus speciosus)、彩色豆马勃(Pisolithus tinctorius)、黄色须腹菌(Rhizopogen luteous)、紫金蜡蘑(Laccaria aemthystea)、黄豹斑鹅膏(Amanita pantherina)等外生菌根真菌对马尾松养分利用的影响，分析了马尾松外生菌根苗的生长及各菌根苗对氮、磷、钾的吸收利用情况。结果表明：菌根菌对马尾松苗高、地径均有显著促生效果；马尾松菌根苗对氮、磷、钾的吸收利用能力增强；各菌根菌对松苗的促生效果与氮、磷、钾的利用表现出一定相关性；各马尾松菌根苗根系酸性磷酸酶含量均比对照提高100%以上。
Abstract
The effects of seven kinds of ectomycorrhizal (ECM) fungi (including Boletus edulis, Boletus speciosus, Pisolithus tinctorius 1, Pisolithus tinctorius 2, Rhizopogen luteous, Laccaria aemthystea, Amanita pantherina) on nutrients absorption were investigated. Their relationships with the growth of host plant and masson pine seedlings were inoculated with seven species of ECM fungi. The seedlings growth were measured. The nutrients (nitrogen, phosphorus and potassium) absorption and utilization were studied. The results showed that ECM fungi promoted the growth of height and root collar diameter of the seedlings obviously. It also enhanced the absorption and utilization of nitrogen, phosphorus and potassium. The content of acid phosphatase in ectomycorrhizal seedlings increased by more than 100% if it was compared with the control.
