盆栽芍药泥炭替代型有机栽培基质研究

Organic Peat-substitute Medium on Cultivation of Potted Herbaceous Peony

以发酵过的菇渣、玉米芯颗粒部分或全部替代泥炭,进行芍药品种大富贵的盆栽试验;以传统泥炭为主的栽培基质配方为对照,设置7种代用型栽培基质配方(其中含泥炭的3种,不含泥炭的4种),分别测定其基本理化性质及营养元素含量;比较各栽培基质对盆栽芍药的地上、地下生物量的影响,从而筛选出适宜芍药盆栽生产的泥炭替代型有机栽培基质配方:40%泥炭+20%菇渣+20%珍珠岩+20%陶粒(体积比)。

Fermented mushroom residues and corn cob granule are used as ingriedient of growing meda in the cultivation of pot Paeonia lactiflora var.＇Da Fu Gui＇,for searching alternative of peat moss.To screen a much better one,altogether seven different kinds of peat-substitute growth medium（among these,three ingredients have peat moss while the other four haven＇t） are arranged,which contradistinguished by a traditional peat moss ingredient.Some basic physical and chemical characteristics of the medium are tested.Besides,to research the influence of the medium,some statistics comparison based on the observation of plant and root biomass are carried out.The result shows that the ingredient 40% peat moss ＋ 20% mushroom residues ＋ 20% perlite ＋ 20% ceramsite（volume ratio） gets the best cultivation effect.
