摘要: 本文就我国亚热带湿热少日照湿性常绿阔叶林生态型区条件下,对乔砧苹果幼树密植早果丰产的一些技术参数进行的田间试验结果表明:六项基础结构参数与早期产量形成密切相关。在该生境下,全冠等幼树具超长枝,多次枝和腋花芽结果性,为早果丰产的枝类结构基础。对旺枝摘心同时摘除先端2-4片幼叶,可控旺长,促分枝成花,成形矮化紧凑。定植苗多留根、干可加强整体营养生长。为早果丰产栽培技术提供了依据。

Abstract: This test was conducted in a damp and hot subtropical region with short sunshine hours. This region belongs to wet evergreen broad-leaved forest. Six basic structure parameters have been found to be closely correlated with early yield. In this ecotype region, young apple trees suck as Golden Delicious are characterized by super long shoot, repeatedlygrowing shoot, and fruiting of axillary flower buds. They constitute the shoot structure basis of early fruiting and high yield. Excessive growth cart be controlled efficiently by picking off actively growing shoot tips and 2 to 4 young leaves on vigorous shoots with 5 to 20 leaves. This treatment also promotes branch and flower bud initiation in the growing season. Then a dwarfing, compact crown is formed. Retaining more roots and trunks at the time of field planting enhances vegetative growth of the whole tree.
