有机质在土壤中起着重要作用，作为粮食生长所需营养物质的重要来源，一直受到各国学者的普遍重视。粮食产量随着有机质含量的增加而增高，但并不是有机质越高，产量越高，粮食产量在一定范围内与有机质含量的多少呈现正态分布。高产土壤对有机质有影响，同时后者制约着前者，土壤属性、耕作、施肥等因素对两者也都有影响。从粮食产量与土壤有机质关系出发，对目前还存在主要问题及今后的研究方向进行了展望。

Organic matter plays an important role in the soil, as an important source of required nutrients for food crops. Most of studies have focused on the base - soluble fractions of organic matter. The grain yield increased with the increasing organic matter content, but not the organic matter higher the yield higher, grain yield within a certain range of the organic matter content of normal distribution. High yield soil Influents organic matter, the latter also restricts the former, soil properties, tillage, fertilization and other factors also have an impact both. From the relationship of grain yield and soil organic matter, the problem of present research status and some recent advances in the isolation.
