浙麦冬根际菌根真菌多样性及土壤性状研究

目的：研究浙麦冬根际菌根真菌多样性以及种植地土壤性状。方法：用湿筛法获得麦冬根际土壤的丛枝菌根真菌孢子,计数孢子密度、物种丰富度及各物种的出现频率;分析浙麦冬种植地土壤性状及金属含量和农药残留。结果：浙麦冬根际土壤中丛枝菌根资源丰富,孢子密度平均824.33个/100g土壤,球囊霉属、巨孢囊霉属和无梗囊霉属为优势类群;菌种丰富度平均为5。丛枝菌根真菌孢子的分布呈明显的季节性变化。种植土壤含有丰富的钙、镁、锌、铜、铬等金属元素,无农药残留。结论：浙麦冬根际含有丰富的球囊霉属、巨孢囊霉属和无梗囊霉属等菌根真菌,其分布具有明显的季节性;根际土壤含有丰富的钙、镁、锌、铜、铬等金属元素。

Rhizosphere Fungi Diversity and soil properties of Ophiopogon japonicus Geo-authentic in Zhejiang Province

This is a study of fungi diversity of Radix Ophiopogonis roots grown in Zhejiang Province and associated soil properties. In the study, a wet screening method was employed to collect arbuscular spores from the soil where Radix Ophiopogonis roots were growing. Authors calculated the density of spores, species affluence, and appearance frequency of different species, and analyzed soil properties, and associated metal content and pesticide residues. Authors found that Radix Ophiopogonis roots grown in Zhejiang Province are rich in arbuscular resources, with a density of spores at 824.33/100g in number. Glomus, Gigaspora, and Acaulospora are the dominant species, with a fungi affluence reaching 5. Arbuscular spores have developed a distribution pattern featured with distinct seasonal variations. The soil where Radix Ophiopogonis roots are grown is rich in metal elements, including calcium, magnesium, zinc, copper, and chromium, without pesticide residues. Authors believe that Radix Ophiopogonis roots grown in Zhejiang Province are rich in fungi, including Glomus, Gigaspora, and Acaulospora, with a distinct seasonal variation. It also has a soil that is rich in calcium, magnesium, zinc, copper, and chromium.
