摘要
为减少泥炭的开采和提高废弃物资源的回收再利用率,探讨建筑废弃物和园林废弃物作为立体绿化栽培基质原料的可行性,将建筑废弃物、园林废弃物和黄壤土作为原料,按三因素三水平正交试验,最终得到了8种栽培基质配方。对不同栽培基质配方的容重、通气孔隙度、最大毛管持水量、有机物含量、有效磷、速效钾、碱解氮和pH值进行测定,结果表明:配方2(园林废弃物∶建筑废弃物∶黄壤土=1∶1.5∶1)符合《立体绿化栽培基质通用技术标准》(T/CABEE 005—2020)相关要求,与商品化基质和常规黄壤土相比,对佛甲草Sedum lineare、锦竹草Callisiarepens和大花马齿苋Portulacagrandiflora生长促进效果更为明显。
In order to reduce the exploitation of peat and improve the recycling of waste resources,and to explore the feasibility of building waste and greening waste as raw materials for vertical greening cultivation substrate was studied.8 kinds of cultivation substrates were obtained by using construction waste,greening waste and yellow loam through orthogonal design trial L9(33).Determination of bulk density,aeration porosity,water holding capacity,the organic compound,available phosphorus,exchangeable potassium,hydrolyzable nitrogen,and pH of different cultivation substrate formulations showed that No.2(greening waste∶construction waste:yellow loam=1∶1.5∶1)met the requirements of the Technical Standard of Cultivation Substrates for Vertical Greening(T/CABEE 005-2020).It had a more pronounced growth-promoting effect on Sedum lineare,Callisia repens and Portulaca grandiflora compared with commercialised substrates and yellow loam.
