| 摘 要： | Iucubation experiments were conducted to investigate the dynamics of low-molecular-weight aliphatic acids i two andosols with and without plant materials.Results showed that amount of low-molecular-weight aliphatic acids in soils alone varied considerably with water regime under which the soil was incubated,duration of incubation and soil organic matter content,ranging from 257-860μmol kg^-1 soil,of which 19%-33% was in free state.Incorporation of plant matrials increased greatly both the amount and unmber of members of low-molecular-weight aliphatic acids,and also the proportion of low-molecular-weght aliphatic acids occurred in free state ,Generally,among these ,aliphatic acids detected,acetic,propionic,glyoxalic and formic acids were predominant.
