摘要 为探明N、P、K配合施肥对长白山欧李(Prunus humili(Bge)Sok)果实中Ca、Fe、Zn元素积累及产量、品质的影响,以5年生长白山欧李的优良品系"02-12-19"为试材,进行了N、P、K配合施肥试验。结果表明:不同N、P、K质量分数配合比例对长白山欧李果实中Ca、Fe、Zn元素的积累均具有一定的影响,其中果实中Ca的积累以质量分数w(N)∶w(P)∶w(K)=1.0∶0.6∶1.0的最高,w(N)∶w(P)∶w(K)=1.0∶0.2∶1.0、w(N)∶w(P)∶w(K)=1.0∶0.4∶1.0、w(N)∶w(P)∶w(K)=1.0∶0.8∶1.0三个处理次之;果实中Fe的积累以单一施用有机肥及w(N)∶w(P)∶w(K)=1.0∶0.2∶1.0、w(N)∶w(P)∶w(K)=1.0∶0.4∶1.0、w(N)∶w(P)∶w(K)=1.0∶0.6∶1.0四个处理较高;果实中Zn的积累以单一施用有机肥及w(N)∶w(P)∶w(K)=1.0∶0.2∶1.0两个处理较高;w(N)∶w(P)∶w(K)=1.0∶0.2∶1.0和w(N)∶w(P)∶w(K)=1.0∶0.4∶1.0的增产效果最佳;食用品质以单一施用有机肥及w(N)∶w(P)∶w(K)=1.0∶0.6∶1.0、w(N)∶w(P)∶w(K)=1.0∶0.8∶1.0两个处理较好。综合配合施肥对欧李果实Ca、Fe、Zn积累及产量、品质形成的影响效果,则以w(N)∶w(P)∶w(K)=1.0∶0.6∶1.0施肥效果最佳。 We used five-year old "02-12-19" fine lines of Prunus humili to study the effects of N, P, and K formula fertiliza- tion on Ca, Fe, and Zn accumulation, yield, and quality of Prunus humili. The different N, P, K formula fertilization had the effects on Ca, Fe, Zn accumulation in Prunus humili fruits. The Ca accumulation in fruits in the treatment of 1.0 : 0.6 : 1.0 of N : P : K was the highest, followed by 1.0 : 0.2 : 1.0, 1.0 : 0.4 : 1.0, 1.0 : 0.8 : 1.0. The Fe accumulations in fruits in four treatments of single organic fertilizers and 1.0 : 0.2 : 1.0, 1.0 : 0.4 : 1.0, 1.0 : 0.6 : 1.0 of N : P : K pro- portion were higher, the Zn accumulation in fruits in two treatments of single organic fertilizers and 1.0 : 0.2 : 1.0 of N, P, K were higher; In yield increasing aspects, the two treatments of 1.0 : 0.2 : 1.0 and 1.0 : 0.4 : l.O of N : P : K pro- portion were better, followed by 1.0 : 0.6 : 1.0 of N : P : K proportion. In edible quality aspects, two treatments of single organic fertilizers and 1.0 : 0.6 : 1.0, 1.0 : 0.8 : 1.0 of N : P : K proportion were better. Therefore, considering the effects of formula fertilization on Ca, Fe, Zn accumulation, yield and quality of Prunus humili, 1.0 : 0.6 : 1.0 of N : P : K proportion was the best.
