摘要
植被覆盖是公路边坡防护的措施之一,而土壤中的有机质含量对促进植物生长至关重要。为此,采用对比试验的方法,研究了在土壤中铺设锯末后,有机质的流失情况以及植物的生长状况。结果表明:在同样气候条件下以及植物生长周期内,未铺设锯末土壤中的有机质下降较多;气温较低月份,铺设锯末土壤中的有机质要高于未铺设锯末土壤25%。试验结果对于坡面工程的水土保持具有推广应用价值。
Vegetation coverage is one of the protection measures for highway slope, and the soil organic content plays an important role in promoting vegetation growth. For the slope projects, we study the organic content variation law in soil after the sawdust is mixed into the slope soil, and the vegetation growth is observed and compared. The results show that for the same vegetation growing period and climate condition, the soil without sawdust losses more organic content; in cold days, the organic matter in the soil containing sawdust is 25% more than that in the soil without sawdust. The results have significant meanings for soil and water conservation of highway slope projects.
