调查了青海省大通县东峡林场一处羊肚菌的生态环境,测定了土壤中的含水量、pH值、有机质、总氮和总磷含量。调查发现羊肚菌的发生与降雨量呈正比;pH值为中性偏碱性基质条件更适合羊肚菌发生;土壤总氮与有机质含量呈正相关,有机质丰富的土壤总氮含量也较高。
The ecological environment of Morchella Morchella in Dongxia Forest Farm in Datong County of Qinghai Province was investigated. The content of water, pH, organic matter, total nitrogen and total phosphorus in soil were measured. It was found that the incidence of Morchella was directly proportional to the amount of rainfall. The pH value of neutral to alkaline substrate was more suitable for Morchella. The content of total nitrogen in soil was positively correlated with the content of organic matter, and the content of total nitrogen in organic matter-rich soil was also high.
