- 摘要:
- 为探寻严重退化羊草草地的合理建植方式,提高草地的耐刈性和稳定性,选取6种改良措施,即围栏封育、松土补播羊草、深耕翻种植羊草、深耕翻种植无芒雀麦、深耕翻种植无芒雀麦与紫花苜蓿、深耕翻种植紫花苜蓿分析重建组合群落生产力,评价重建效果。结果表明:各重建措施对退化草地在数量和质量上都有明显的改良效果,深耕翻种植羊草改良草地3~4年后,其植被盖度可达90%,鲜草增产率可达60%以上,增产达到5 194.65 kg?hm-2,且植被类型丰富。
- Abstract:
- In order to explore the reasonable vegetation reconstruction method of severe degenerative grassland,improve the resistance and stability of grassland,the paper mainly selected six reconstruction methods such as fencing,light harrow reseed Leymus chinensis,deep ploughing and planting Leymus chinensis,deep ploughing and planting Bromus inermis,deep ploughing and planting Bromus inermis and Medicago sativa,deep ploughing and planting Medicago sativa,analyzed their community productivity and evaluated effect of grassland vegetation reconstruction.The results showed that the reconstruction measures could obvious improve forage grass quantity and quality of degraded grassland,the output of fresh grass increased by 60% with 5 194.65 kg?hm-2 and the vegetation types were abundant.
