摘要:
通过人工模拟降雨与室内分析相结合的方法.对美国引进的8种禾本科牧草的生长势能、持水能力及草地的土壤水分状况、物理性状、土壤抗蚀性、贮水量、水土保持作用等指标的初步研究,结果表明:种植牧草可增大地表粗糙度,减轻地表水蚀,达到防止水土流失的目的.并通过生物改良和阻滞溅蚀增强土壤抗蚀性;其中,无芒雀麦、苇状羊茅、扁穗冰草、细颈披碱草的水保综合性能表现最为优秀,披碱草、新麦草、高冰草表现一般,猫尾草表现较差.
Abstract:
To probe into the effects of the 8 kinds grass soil and water conservation,the growth function,the ability of holding water,the water content in the soil etc,are measured through an artificial emulation rain with indoor analysis combine together.The result shows that Bromus inermis Leyss.,Festuca arundinacea Schreber,Agropyron desertorum,Agropyon trachcaulum are the most excellent,Elymus dahuricus,Elymus junceus Fischer,Agropyron elongatum performance general,Phleum pratemse L.performance worse.
