Abstract No-tillage is an important farmland management practice. It is the core content of conservation tillage system and has been widely applied all over the world. Based on previous studies， the effects of no-tillage on soil physical， chemical， biological properties as well as crop yield were summarized in order to provide support for the development of no-tillage.
