[目的]本研究比较了SH_1和Y-1两种中间砧对长富苹果树体营养生长的影响,为中间砧的选择应用提供理论依据。[方法]以3年生矮化中间砧苹果树(长富2号/SH_1和Y-1/八棱海棠)为试材,对其枝条和叶片的生长势进行统计分析。[结果]以Y-1矮化中间砧的苹果树新梢长度极显著低于SH_1矮化中间砧苹果树,短枝率(64.43%)显著高于SH_1树体(44.45%),长枝比例(10.50%)显著低于SH_1树体(19.21%),秋梢节间长度显著短于SH_1,短80.51%,叶片厚度、比叶重和类胡萝卜素高于SH_1树体,但差异不显著。[结论]Y-1矮化中间砧更有利于长富苹果树体矮化,树体长势中庸,易积累营养物质。
[Objective] The purpose of this study was to compare the effects of two kinds of intermediate stock (SH_1 and Y-1) on the vegetative growth of apple tree, and to provide the theoretical basis for the selection and application of the intermediate stock. [Method] The apple tree (Changfu No.2 / SH_1 and Y-1 / Bailuangtang) with 3-year-old dwarfing intermediate anvil was used to study the growth potential of its branches and leaves. [Result] The shoot length of apple tree with Y-1 dwarfing anvil was significantly lower than that of SH_1 dwarfing anvil, the rate of shrub (64.43%) was significantly higher than that of SH_1 tree (44.45%), (10.50%) was significantly lower than that of SH_1 tree (19.21%). The internode length of autumn was significantly shorter than that of SH_1 and short 80.51%. Leaf thickness, leaf specific weight and carotenoid content were higher than SH_1 tree, but the difference was not significant. [Conclusion] The Y-1 dwarfing intermediate anvil was more conducive to the dwarfing of the apple-rich tree, the growing of the tree body, and easy accumulation of nutrients.
