摘要
通过对新建植的放牧型扁穗牛鞭草混播草地在超载条件下连续4年的植被调查分析,探讨了该草地的放牧演替规律,结果表明,采用扁穗牛鞭草+狗牙根+百喜草+苇状羊茅+多年生黑麦草+白三叶混播组合,可建立扁穗牛鞭草+狗牙根一百喜草一白三叶型草地,该草地超载利用多年,植物群落稳定,生产力高,耐牧性好,可作为我国温暖湿润气候区放牧型人工草地的适宜类型.
Based on an investigation and analysis, which lasted for four continious years on the vegetation of the newly-built, grazing-type Compressed Hemarthia mixing grassland under the condition of over-grazing, this essay probes the grazing succussion regularity of the target grassland. It shows that the grassland in the type of Hemarthria compressa （L.f） R.Br.＋Cynodon dactyon L.-Paspalum notatum flugge.-Trifolium repens L. can be built by the following type of combination： Hemarthria compressa （L.f ） R.Br. ＋ Cynodon dactyon L. ＋ Paspalum notaturn flugge. ＋ Festuca arundinacea schreb. ＋ Lolium perenne L. ＋ Trifolium repens L., This type of grassland can be utilized under the over-grazing condition for many years. Its plant community remains stable, A high productivity is kept and the grazing capability is sustained. Therefore it is a suitable type for the sown grazing-type grassland in the warm and humid climate regions in our country,
