摘  要：
在对陕西省猕猴桃产区53个红阳猕猴桃园普查的基础上,选择5个管理水平较高的红阳猕猴桃果园,对其树体结构及土壤养分状况进行分析。结果表明:高产稳产型红阳猕猴桃树体的合理结构为成龄树冬季修剪后单株保留12～16个结果母枝,对长果枝剪留8～12个芽,折合667m2留长枝量为1 200～1 600个,留芽量为10 000～15 000个。7月份单株保留有效叶片在1200个以上,叶果比为4.66∶1,长枝∶中枝∶短枝=24∶21∶94;土壤养分状况是速效氮为27.0mg/kg,速效磷为100.6mg/kg,速效钾为507.1mg/kg,速效铁为3.450mg/kg,有机质含量为1.927%,速效磷、速效钾及有机质含量水平较高。

摘  要：
Based on the investigation of 53 orchards in Shaanxi kiwifruit Areas,tree structure and soil nutrients of 5 best orchards were analyzed.The results showed that the quick-release nitrogen was 27 mg/kg,the quick-release phosphor was 100.6 mg/kg,the quick-release potassium was 507.1 mg/kg,the quick-release iron was 3.450 mg/kg,and the organic matter contents were 1.927%,in the best kiwifruit orchard.Higher phosphor,potassium and organic matter in kiwifruit orchard soil was good for production of Hongyang Kiwifruits variety.Keeping 12~16 fruit shoots per plant and 8~12 buds per shoot after winter pruning,leaf and fruit ratio 4.66,over 1 200 leaves per plant in growth season was necessary for getting higher yields.Which was suitable for the Hongyang Kiwifruits production.
