刈割对牧草生物量和品质影响的研究进展

Research progress of clipping effect on quality and biomass of grazing

刈割是一种常见的草地利用和管理方式,它可以通过两方面途径来影响牧草产量及品质。首先,刈割可以利用植物的补偿性生长,促进牧草生长并提高牧草产量。其次,刈割可以利用植物均衡性生长特性,改变牧草营养物质的沉积和分配方向,进而影响牧草品质。常见的刈割包括刈割频次、刈割时间和刈割方式。全面综述3种刈割对牧草产量及品质影响和相应作用机理,为适当利用刈割提高牧草产量及品质提供参考。

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.
