| 摘 要： | 碳水化合物是土壤有机质的组成分之一.一般认为,它在土壤良好结构的形成中起着重要的作用1].根据Waksman和Stevens的“近似分析法",各种土壤的有机质中,“半纤维”的含量约在5-20%间,“纤维”的含量在0-5%间2].但是这种方法并不能提供关于土壤碳水化合物本性方面的资料.近年来,借助于分离的方法,已经证明各种土壤中都有微生物来源的多糖存在.

| Abstract: | The present paper gives the composition of carbohydrates in some soil groups and its distributions in different organic fractions and in soil profile.Soil samples used inelude alpine steppe soil,brown podzolic soil,prarie soil,dark chestnut soil,salinized steppe soil,black loam soil,laterite and paddy soil.It was found that all the surface soils examined under natural vegetation,irrespective of their divergent vegetative and climatic conditions,resembled each other in the pattern of component sugars.In general,the relative concentration of glucose was slightly higher than that of other sugars,the other sugars decreased in the following order:galactose,xylose-arabinose,rhamnose.The relative concentration of mannose though varied in different soil types,was usually higher rhan that of xylose and lower than that of glucose. |
