摘　　要：硬水显著抑制一品红生长，在口径15．5cm、容积1．85L的花盆中，每盆加入4．2g配方为15％N＋11％R05＋13％K2O＋2％CaO的控释肥做基肥，上盆后施用较低浓度（0．25～0．50g／L）的水溶性复合肥可有效缓解硬水对‘自由’一品红生长的抑制作用，提高盆花品质。In order to alleviate the inhibiting action of hard water on growth of poinsettia a potculture experiment of poinsettia was carried out by applying controlled-release fertilizer and water-soluble fertilizer. The result showed that using controlled-release fertilizer of 15% N ＋ 11% P2O5 ＋ 13% K2O＋ 2% CaO as a basal fertilizer at a rate of 4.2 g per pot （1.85 L） and applying water-soluble fertilizer at a low rate of 0.25-0.50 g/L after potting could effectively alleviate the inhibiting action of hard water and improve the pot flower quality.
