Abstract

Abstract:

Promoting sustainable agricultural development and advocating conservation tillage has become a new direction of world agricultural development. Biological tillage represented by cover crops has been widely concerned by scientists at home and abroad because of its unique ecological value and field effects. Cover crop refers to the crop that fills the bare space of soil in time and space during the growth of main crop and after harvest. In winter, it can be returned to the field or used as silage, which plays an important role in the growth of main crops and the improvement of soil properties. Based on the research at home and abroad, this paper briefly introduced the field application of cover crops, including the origin, species, function, management mode and feed use of cover crops, and expounded many benefits of cover crops to farmland. It is expected to provide theoretical reference for alleviating the contradiction between grain and forage land and promoting the field application of cover crops.
