摘要
通过多点调查的方法,以生态学观点研究了黔中丘陵地区人工草地建植方法以及轻度放牧对草地产量、草地稳定性的影响。结果表明,黔中丘陵地区因山地高度不同,使各地段土壤肥力、水分状况产生差异,将影响人工草地成坪时间、草地产量和稳定性;轻度放牧行为有利于草地生长发育和提高草地产量。并对该类地区常用播种方式提出了修正意见。
After being built artificial grassland in south China, it would be declined with grass output and stability. In this paper, the influence of building ways and light grazing on the artificial grassland yield and grass stability were investigated with viewpoint of ecology in the hill area of Middle Guizhou.On the hill, it is indicated that the soil fertilizer and moisture in the soil will influence the artificial grassland output and grass stability.The promoting efficiency with light grazing on grass growth and grassland output is discussed, too.
