青海省羊肚菌发生地的生态环境调查

Investigation of Ecology Environment on Morchella in Qinghai Province

调查了青海省7个不同地区羊肚菌的生态环境,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值为中性或略偏碱性的基质条件更适合羊肚菌生长;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。

Ecological environment of Morchella in seven different areas of Qinghai province were studied, the water content of soil, pH value, organic matter, total nitrogen and total phosphorus content was measured. Survey found that the occurrence of Morchella and rainfall were positively correlated, pH value under the condition of neutral or slightly alkaline substrate was more suitable for Morchella growth. Soil total nitrogen and organic matter content were positively correlated, rich in organic matter of soil total nitrogen content was also higher.
