| 摘 要： | 以8年生‘嘎啦’苹果/平邑甜茶为试材，研究了相同施氮量下其对一次和分次施15N–尿素的吸收、分配与利用情况。结果表明：一次性和分次施肥处理，果实成熟期植株各器官从肥料中吸收分配到的15N量对该器官全氮量的贡献率（Ndff）差异显著，分次施肥处理各器官Ndff显著高于一次施肥处理。分次施肥处理，新梢旺长期和果实膨大期果实和根系的Ndff均低于一次施肥处理，但在果实成熟期均高于一次施肥处理。果实成熟期测定，生殖器官分配率最高，营养器官和贮藏器官均较低，处理间差异不显著。分次施肥处理15N利用率为32.2%，显著高于一次施肥处理（23.34%）。

| Abstract: | The characteristics of absorption,distribution and utilization of eight-year-old'Gala'apple(Malus domestica/Malus hupehensis)under the treatment of once and split fertilization were studied.The results were as follows:At the fruit maturity stage,Ndff values in different organs were obviously different,and Ndff values of the organs were generally higher in split fertilization than once fertilization.However,the Ndff value of fruits and roots in split fertilization was lower than that of once fertilization at... |
