高寒草甸白蘑菇圈与圈外植物及土壤的比较

A COMPARISON BETWEEN MUSHROOM SPHERE ANDPLANTS OUTSIDE THE SPHERE AND SOIL IN ALPINE MEADOW

１９９４年测定了高寒草甸白蘑菇圈与蘑菇圈外植物的地上生物量、营养成分和土壤养分。结果表明：蘑菇圈带上的植物地上生物量比蘑菇圈外高２１５％；植物粗蛋白含量高５６％；土壤速效氮和速效磷含量分别高２１％和５８％。

The aboveground biomass, nutrients and soil nutrients of mushroom sphere and plants outside the sphere in alpine meadow were determined in 1994. The results showed that the aboveground biomass inside the sphere was 215% more than outside; the contents of plant crude protein was 56% more, and 21% and 58% more in rapidly available N and P, respectively.
