Abstract

Abstract:

Soil bacteria community and their diversity were studied during the leaf litter decomposition of Larix olgensis× Larix kaempferi plantation with different densities by two mesh size of litterbags, that is, top layer of 2 mm mesh and bottom layer of 1 mm mesh (mixed mesh litterbag), as well as 1/300 mm mesh size(same mesh litterbag)of litterbags. The bacteria were investigated with the plate cultivation method and PCR-16S RNA sequence analysis. The result showed that the number of soil bacteria was changed significantly (F=10.97, P<0.01) during leaf litter decomposition. The bacteria participating in cellulose, hemicellulose decomposition, such as Bacillus, Pseudomonas, Staphylococcus, was the most dominant. The variety of bacteria community was not consistent between the two types of litterbags. The number of bacteria in the same mesh litterbag increased with the plantation density and some species were obviously dominated, while the number of bacteria in the mixed mesh litterbag decreased with the plantation density and there were no significant dominant species. The composition and diversity of soil bacteria community were mainly influenced by the sampling period. Soil bacteria communities were similar among the different densities of Larix olgensis×Larix kaempferi plantation. The plantation density had different effect on soil bacterial diversity and complexity during leaf litter decomposition of two types of litterbags. The canonical correlation analysis showed that the environmental conditions suitable to soil bacterial community were similar. Soil potassium had the most effect on distribution of soil bacteria, while the ratio of soil carbon to nitrogen had the least effect.

Key words: larch, soil bacteria community diversity, litterbag, dynamic, soil property, canonical correspondence analysis
