【摘要】 通过将纤维素脲醛泡沫基质分别以1/3、2/1、2/3、1比例取代一般园林用土,在建筑物墙面绿化(垂直绿化)中,对鸟巢蕨、红掌、袖珍椰子进行了栽培研究。纤维素脲醛泡沫基质的添加可提高基质的孔隙度、吸水率,降低基质的容重。完全采用纤维素脲醛泡沫基质时,其结构轻质、营养充分的优势极为明显,垂直绿化植株生长健壮,植株鲜重、株高、冠幅等指标表均优于其他栽培基质配比。更多还原

【Abstract】 The study investigated the effects of the cellulose reinforced urea formaldehyde foam on growth of the vertical greening plants. The plant substrates were prepared by replacement of general garden soil in various volume proportions,like 1/3,2/1,2/3 and full replacement. The bird’s Nest Fern,Anthurium and the pocket coconut were selected for cultivation experiments. The addition of the synthetic material can increase the porosity and water absorption of the matrix,and reduce the bulk density of the substrate. Full use of cellulose reinforced urea formaldehyde foam as plant growth substrate for vertical greening has several advantages,such as light structure and adequate nutrition supply. The cultivation results indicated that vertical greening plants had stronger growth,fresh plant weight,plant height and crown width index.更多还原
