Research progress of clipping effect on quality and biomass of grazing

Clipping is one of common ways in using and management of grassland. It can affect the biomass and quality of grazing by two approaches. Firstly, clipping can accelerate the growth speed and enhance the biomass of grazing by using the compensation growth of plant. Secondly, clipping can change the aggradations of nutrition and direction of distribution of grazing by the functional equilibrium of plant, and then affect the quality of grazing. The hackneyed methods of clipping include the frequency of clipping, the time of clipping and the mode of clipping. This paper was expounded the influences and mechanism for the biomass and quality of grazing in order to offer the consult for the suitable clipping.
