摘要: 采用美味牛肝菌(Boletus edulis,简称Be)、黄色须腹菌(Rhizopogen luteous,简称Rl)及其混合菌剂分别对湿地松苗接种,以小区对比试验设计,观测接种后的湿地松菌根形成率、成活率、生长量及叶绿素含量。结果表明:接种外生菌根真菌可以显著提高湿地松的菌根形成率和成活率,增加松苗叶绿素含量,对松苗具有显著的促生长效应。同时对接种后的湿地松根际土壤微生物数量进行了测定,结果表明:湿地松根际细菌数量显著增多,真菌数量显著减少,放线菌数量明显增多。

Abstract: The mycorrhizal infection rate, survival rate, growth and chlorophyll content of Pinus elliottii seedlings inoculated with Boletus edulis, Rhizopogen luteous and double inoculated with Be and RI were investigated. A plot comparative test was used in the experiment.The results indicated that the ectomycorrhizal fungi could improve the mycorrhizal infection rate, survival rate and increase the content of chlorophyll in Pinus elliottii seedlings. It had a significant growth promoting effect on pine seedlings. The quantity of rhizosphere microrganisms in P. elliottii seedlings was also determined in this study. Results showed that the number of rhizosphere bacteria significantly increased, rhizosphere fungi significantly reduced, and the quantity of actinomyces increased obviously. The technology of ectomycorrhizal fungal inoculation provided theoretical basis and practical guidance for the pine afforestation.
