微生物是土壤有机组织中最多种多样的群体，然而我们对它们知道得很少。直到最近，调查才集中在那些可培养的有机体上；不过，我们正在从可培养的，到现在还有不可培养的有机体中收集丰富的资料，土壤微生物群落的机能影响着很多土壤工艺，并且因此影响着生产能力。如果没有微 Microorganisms are the most diverse and diverse group of soil organic matter, yet we know little about them. Until recently, investigations were focused on those organisms that were culturable; however, we are gathering abundant information from cultivable, up to now uncultivable organisms, and the functioning of soil microbial communities affects many soil processes, and as a result Affect the production capacity. If not micro
