为了更好突出北京西山国家森林公园的花卉景观效果,引入了射干(Belamcandachinensis)、八宝景天(Sedum spectabile Boreau)、柳叶马鞭草(Verbena bonariensis)、玉簪(Hostaplantaginea Aschers)4种地被植物,采用播种或植苗的种植方式进行栽植。选用正交试验设计方法对上述4种地被植物在公园的表现进行了研究。试验以单位面积花密度为考量指标,考察了不同的立地条件、种植密度、养护周期3种因素对单位面积花密度的影响,通过试验对比,挑选出地被植物花密度最佳的种植条件,在公园进行推广,达到提升公园景观的目的。
In order to better highlight the landscape effects of flowers in Xishan National Forest Park in Beijing, four kinds of ground cover plants (Belamcandachinensis, Sedum spectabile Boreau, Verbena bonariensis, Hostaplantaginea Aschers) , Planted or planted by planting seedlings planted. Orthogonal experimental design method was used to study the above four kinds of vegetation in the park performance. In the experiment, the flower density per unit area was taken as the index to investigate the influence of three kinds of factors such as site conditions, planting density and curing cycle on the flower density per unit area. Through experiment and comparison, the best planting density of ground cover plants was selected, In the park for promotion, to enhance the park’s landscape.
