摘　　要：为了明确棱柄马鞍菌的发生与生态环境、土壤环境的关系,进而为棱柄马鞍菌的驯化栽培提供一定的参考依据,调查了山西岢岚地区马鞍菌发生处的生态环境和气候环境,测定了土壤养分含量,并进行了马鞍菌形态学分析。结果表明,在山西,棱柄马鞍菌发生在夏末秋初降雨过后的针叶林、次生林中,气温在10~27℃,土壤pH呈中性偏碱性,且根际土壤与非根际土壤pH无显著差异。同时,根际土壤中有机质、碱解氮、有效磷、速效钾含量明显高于非根际土壤。因此,在有机质、碱解氮、有效磷、速效钾含量高的中性偏碱性土壤中更容易发生马鞍菌。In order to clarify the relationship between the occurrence of Helvella lacunosa and the ecological environment and soil environment,and then provide some reference for the domestication and cultivation of Helvella lacunosa,this study investigated the ecological environment and climate environment where Helvella lacunosa occurred in Kelan,Shanxi Province,and determined the soil nutrient content,and carried out morphological analysis of Helvella lacunosa.The results showed that in Shanxi,Helvella lacunosa occurred in coniferous forests and secondary forests after rainfall in late summer and early autumn.The temperature was between 10 and 27℃,and the soil pH was neutral and alkaline,and there was no significant difference between the rhizosphere soil and non-rhizosphere soil pH.At the same time,the contents of organic matter,alkali-hydrolyzed nitrogen,available phosphorus and available potassium in rhizosphere soil were significantly higher than those in non-rhizosphere soil.Therefore,Helvella lacunosa was more likely to occur in neutral alkaline soil with high contents of organic matter,alkali-hydrolyzed nitrogen,available phosphorus and available potassium.
