摘要
通过对5年生幼龄枣树叶幕形成全部过程的观察,初步掌握了在咸阳市渭北地区的自然条件下,枣树叶幕形成受外界气温和枣股的发育营养状况影响,及不同年龄枣股上抽生冬吊及着叶特点,从而为幼龄枣树早果、丰产栽培技木提供了参考依据。
The crown canopy formatoin pattern of 5-year-oid jujube trees was studied. Results show that the annual cycle of leaf area growth of the entire tree is closely related to the air temperature surrounding the orchard and the nutrient status of the dwarf shoots. The growth features of leaves and fruit spurs on the dwarf shoots with a different age are also described.
