| 摘 要： | 为明确猕猴桃果园的生产潜力，在普查的基础上对两个管理水平较高的徐香猕猴桃果园的树体结构及土壤养分状况进行分析。结果表明，高产型徐香猕猴桃树体的合理结构为成龄树冬季修剪后单株保留17个左右结果母枝，每枝保留15~21个有效芽，折合每667 m留长枝量为1 496个，留芽量为22 440~23 760个，7月份叶果比为3.33∶1。土壤速效氮为16.5 mg/kg，速效磷64.8 mg/kg，速效钾209.6 mg/kg，速效镁和速效铁分别156.6 mg/kg和3.58 mg/kg，有机质含量1.13%。可见，充足的肥料投入、枝芽数量及合理的叶果比是高产稳产的基本保证。

| Abstract: | Tree structure and soil nutrients of two well managed orchards were analyzed. The results showed that the high yielding indexes for tree structure of Xuxiang kiwifruits orchard were keeping 17 fruit shoots per plant and 15-21 buds per shoot after winter pruning, leaves and fruit ratio 3.33 in July. The corresponding soil nutrients states in the kiwifruit orchard were 16.5 mg/kg available nitrogen, 64.8 mg/kg available phosphorus, 209.6 mg/kg available potassium, 156.6 mg/kg available magnesium, 3.58 mg/kg available iron, and 1.13% organic matter. Keeping plentiful shoots and buds, fertilizer supplement, and proper leaf fruit ratio is the foundation of higher yields in Xuxiang kiwifruits orchard. |
