通过调查青海省祁连县峨堡乡野生黄绿蜜环菌蘑菇圈发生季节蘑菇圈上、圈外植物群落的物种多样性、植物群落种类组成及多度变化,分析了蘑菇圈上、圈外土壤主要微生物类群的数量变化、土壤水分、速效养分、交换性阳离子及pH等的差异.结果表明,蘑菇圈上和圈外植物群落组成种类不同,圈上物种数明显高于圈外物种数;圈上各物种分盖度总和比圈外高出49.16%,但圈上和圈外优势种及主要伴生种相同.在0～10 cm土壤层,圈上土壤含水量、速效磷、硝态氮、氨态氮的含量明显高于圈外,但土壤有机质、交换性Ca2+、交换性Mg2+和pH值的变化不明显;在10～20 cm土壤层,圈上速效磷、硝态氮、氨态氮的含量仍明显高于圈外,但土壤含水量变化趋势相反,圈外高于圈上.在0～10cm土壤层,细菌、放线菌、真菌及纤维素分解菌的数量,均以圈上显著高于圈外(P＜0.05);在10～20cm土层,它们的数量差异不显著(P＜0.01).在两层土壤中,各类微生物数量表现为:细菌＞放线菌＞真菌＞纤维素分解菌. |

The differences of plant diversity, community composition, number of different taxonomic groups of microor-ganism, and water content on and outside the fairy rings of Armillaria luteo-virens were investigated in Ebao village, Qilian county, Qinghai Province, from July, 1997 to August, 1998. The results showed that the vegeta-tion community on fairy ring was composed differently from that outside of it, but both of them had the same dominant species. The species number and total plant cover on fairy ring were obviously higher than that out-side the ring. In surface soil layer, the water content, available P and N content on fairy ring were significantly higher than that outside the ring, while there were no obvious difference in changeable Ca2+ and Mg2+ , organ-ic matter content and pH, Their trend was similar in deep soil layer except for water content. The number of bacteria, actinomyces, fungi and cellulose decomposer on fairy ring was obviously higher than those outside of it in surface soil layer, respectively, while there was no significant difference between them in deep soil layer. |
