施用生物质炭对采煤塌陷区土壤氨氧化微生物丰度和群落结构的影响
Effects of biochar application on the abundance and structure of ammonia-oxidizer communities in coal-mining area
摘要
Abstract
As a new type of soil amendment,biochar can effectively improve soil fertility,structure and soil nitrogen transformation.We studied the effects of biochar application on soil properties,abundance and community structure of ammonia oxidizer in coal-mining area.The results showed that the biochar application significantly increased contents of soil NH4+-N,total nitrogen,available phosphorus and potassium.Compared with the control,no change in the abundance of ammonia-oxidizing archaea (AOA) was found under biochar treatment,but there was a significant increase in the abundance of ammonia-oxidizing bacteria (AOB).The analysis of T-RFLP profiles showed that biochar significantly increased the diversity indexes of AOA and AOB,and altered the community structure of both AOA and AOB.Improved soil nutrients as well as increased abundance and diversity of ammonia-oxidizing community to some extent indicated the potential of biochar application in reclamation of coal-mining area soil.关键词
