摘要: Abstract A characteristic of paddy soils is that they are kept under a water-logged condition during rice cultivation. It seems quite natural to expect soil harbours microflora not common in upland soils. However, few studies have been made on the soils(1,7). This study was conducted compare these with those reported previous papers(4,5,6).
