摘要: 于2009~2010年在保定市河北农业大学梨园内,选取具有代表性的10a生鸭梨,测定鸭梨不同发育期未套袋果实、套袋果实中营养元素含量,研究套袋和未套袋鸭梨果实中主要营养元素含量变化规律,揭示其含量差异.结果表明:果实中10种营养元素含量随果实的膨大而逐渐减少,套袋和未套袋果实中N、P、K、Ca、Mg、Mn、Cu、Zn、B元素变化规律一致;套袋果实和未套袋果实中N、P、K、Mg、Mn、Cu元素含量基本相同,套袋果实中Fe、Zn元素总含量低于未套袋果实,Ca、B元素总含量高于未套袋梨果实.未套袋果实中各种常量元素总含量顺序为:K>N>P>Ca>Mg,微量元素总含量顺序为:Fe>B>Zn>Mn>Cu.
