武功山高山草甸土壤微生物生物量碳及其影响因素
STUDY ON SOIL MICROBIAL BIOMASS CARBON AND ITS FACTORS IN ALPINE MEADOW IN WUGONGSHAN MOUNTAINS
摘要
Abstract
In the present paper, soil microbial biomass carbon (SMBC) in three hillsides of alpine meadow in Wugongshan mountains and its factors were studied. The results showed that both SMBC and soil organic matter (SOM) contents in the east slope were significantly higher than that in the south slope, and that in the south slope were as well higher than that in the north slope. Contents of available potassium (K) in the east slope were the highest, followed by that in the south slope, the lowest in the northern slope. Contents of available phosphorus (P) in the east slope were significantly higher than that both in south and north slopes. Soil ammonium nitrogen (NH4+-N) contents were the highest in the northern slope followed with that in southern slope and the lowest in eastern slope. SMBC contents in the three slopes were well correlated with SOM and available P contents. There were no significant correlation between contents of SMBC and K, but SMBC contents decreased with the increasing of soil ammonium nitrogen contents.关键词
