- Abstract:
-
In order to explore the characteristics of the soil microbial communities of Cunninghamia lanceolata with forest stand age, in this study, Cunninghamia lanceolata plantation of various ages(7, 24, 34 years)were selected in the middle subtropics. Phospholipid fatty acid(PLFA)method was used to analyse the number and community structure of rhizosphere and non-rhizosphere soil microorganisms and the main soil environmental factors driving the changes of soil microbiome. The results showed that: With the increase of the age of the Cunninghamia lanceolate plantation, the number of microorganisms in non-rhizosphere soil decreased and increased. The contents of bacteria, Gram-negative bacteria and Cy:MONO in 34-year-old Cunninghamia lanceolata plantation were significantly higher than those in non-rhizosphere soil, but there was no significant difference in other microbiome between rhizosphere and non-rhizosphere soil. The results of redundancy analysis(RDA)showed that soil environmental factors had significant effects on the soil microbial community of Cunninghamia lanceolata, in which the contents of available phosphorus and ammonium nitrogen had great influence on soil microbial community, and the content of available phosphorus was positively correlated with soil microbial community. The content of soil ammonium nitrogen was negatively correlated with it. Therefore, in the process of Chinese fir plantation management, the input of phosphorus can be appropriately increased to increase the number of soil microorganisms, improve soil quality and promote the growth of Cunninghamia lanceolate.
