不同基质和容器类型对簕杜鹃生长的影响

Effects of Different Culture Mediums and Containers on the Growth of Bougainvillea spectabilis

为探究簕杜鹃立体绿化应用适宜的栽培基质和容器,以‘同安红’为实验材料,用玻璃钢花盆和塑料花盆作栽培容器,测定混合基质理化性状、植株生物量、叶片氮、磷、钾含量及叶绿素含量。结果表明:基质A3(V (园土)∶V (泥炭)∶V (珍珠)岩∶V (河沙)=2∶4∶3∶1)明显优于其他3种基质,能更好的促进‘同安红’生长;容器B2(玻璃钢花盆)更能促进‘同安红’地下部分生物量积累和根系各项指标生长,且基质和容器类型对簕杜鹃的交互效应主要表现在地上部分干质量、根长和根体积。因此,基质A3和容器B2更有利于促进‘同安红’生长。

To explore the suitable culture medium and container of Bougainvillea spectabilis in overpass greening application in this experiment,B. spectabilis ‘Crimsonlake’was used as testing material which combined with the glass-steel-flowerpots and the plastic-flowerpots. Through the determination of mixed matrix physical and chemical properties,plant biomass,the content of N、P、K and chlorophyll,the effect of different culture mediums and containers on the growth of B. spectabilis ‘Crimsonlake’ were analyzed. Results show that matrix A3(V(the garden soil) ∶ V(peat) ∶ V(perlite) ∶ V(river sand) = 2 ∶ 4 ∶ 3 ∶ 1) is obviously superior to the other 3 substrates for better promoting the growth of B. spectabilis ‘Crimsonlake’. The container B2(glass-steel-flowerpots) is much more beneficial for the biomass accumulation and root growth of the underground part of "B. spectabilis ‘Crimsonlake’". It also demonstrates that the interaction effect of base material and container type is mainly shown in the dry weight,root length and root volume of the overground part. To sum up,the base material A3 and container B2 are more conductive to promoting the growth of B. spectabilis ‘Crimsonlake’.
