【摘要】 硬水显著抑制一品红生长,在口径15.5 cm、容积1.85 L的花盆中,每盆加入4.2 g配方为15%N+11%P2O5+13%K2O+2%CaO的控释肥做基肥,上盆后施用较低浓度(0.25~0.50 g/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。更多还原

【Abstract】 In order to alleviate the inhibiting action of hard water on growth of poinsettia a pot-culture 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.更多还原
