不同基质对无土盆栽牡丹花径的影响

Influence of Different Substrates to the Flower Diameter of Soilless-potted Paeonia suffruticosa

以洛阳红、银红巧对、璎珞宝珠和似荷莲4个牡丹(Paeonia suffruticosa Andr)品种为材料,研究了4种无土盆栽基质对牡丹花朵大小的影响。结果表明,银红巧对是无土盆栽的首选品种,其次是洛阳红和似荷莲;牡丹无土盆栽基质以蛭石∶草炭土=1∶1和珍珠岩∶蛭石∶草炭土=1∶1∶1的配方最好;其次是珍珠岩∶草炭土=1∶1的配方。

The influence of 4 kinds of soilless substrates on the flower size was studied using 4 tree peony varieties （Paeonia suffruticosa cv Luoyanghong, P. suffruticosa ev Yinghongqiaodui, P. suffruticosa cv Yingluobaozhu and P. suffruticosa cv Sihelian） as the material. The result indicated that under the test condition, P. suffruticosa cv Yinghongqiaodui was the best, and P. suffruticosa cv Luoyanghong and R suffruticosa cv Sihelian the second. The best composezation of the substrate was： vermiculite：peat earth=1：1 and pearlite：vermiculite：peat earth =1：1：1, then pearlite：peat earth =1：1.
