兰花栽培基质的要求
兰花栽培基质的要求,基质的选择对于栽培兰花是十分重要的。栽培者应根据当地的实际情况,选择资源丰富、取材容易的材料。栽植兰花对基质的主要要求是:排水通气好,适于根系舒展,有孔隙能蓄水,有一定的肥分,带微酸性。
盆栽时地生兰用土多于附生兰,而基质的颗粒则小于附生兰。此外,用适量的水苔是有益的。常用的基质有:蛇木屑、泥炭土、水苔(水草、泥炭藓)、蕨根、砖块与碎瓦片、土灰与木灰、龙眼树皮、腐殖质、羽毛、碎骨、塘泥球、煤渣、陶粒、蛭石、浮石、棕纤维、发泡砾石与碎石、木炭与椰子壳、保丽龙、珍珠石、纤维人造土。
栽培兰花用的基质可大致分为两大类:块状的基质和非块状的基质。前者如砖块、瓦片、陶粒、珍珠岩、木炭、椰壳、蕨根、树皮等,应敲碎至直径0.5~2厘米,最好不留锐棱角,以免摩擦伤根;后者如腐殖质、塘泥、土壤、沙粒、泥炭土、羽毛等,最好先捣碎,按比例配在一起,加水和匀,晒干后再捣成小块备用,以上就是关于兰花栽培基质的要求的介绍。
