Abstract: Field experiment were arranged under standardized conditions to study the differentiation of soil features Under rice-wheat double Cropping and rice-rice-wheat triple Cropping systems. The results showed that Under triple cropping systems, the content of soil organic matter, whole nitrogen and available phosphorushad a increasing trend compared with double cropping, but the content of active potassium and soil oxidization -reduction potential reflected the opposite trend. In addition, to some extent, the increase of soil organic matter accelerated this ditferentiat trend. If heavy machines Were not Used in cultivation, the soil physical properties under triple cropping did not prove to be substantially worse than those Under double ’cropping.
