摘　　要：本试验以天红2号/SH40/八棱海棠、天红2号/冀砧1号/八棱海棠、天红2号/冀砧2号/八棱海棠为材料,研究SH40、冀砧1号、冀砧2号中间砧4个入土深度(0、10、20 cm和30 cm)对树体生长及苹果果实品质的影响。结果表明,SH40、冀砧1号、冀砧2号中间砧随入土深度增加,树高、干径、枝展、主枝数、外围新梢长度、总枝量基本呈增加趋势。SH40入土10、20 cm处理果实纵径、可溶性固形物含量、固酸比显著高于其它处理,且入土20 cm处理苹果酸含量显著低于入土30 cm处理;冀砧1号、冀砧2号入土20 cm处理单果重、果实纵径、固酸比显著高于其它处理。综合分析认为,三种中间砧适宜入土深度,SH40为10~20 cm,冀砧1号和冀砧2号为20 cm。In this experiment,Tianhong 2/SH40/Malus robusta,Tianhong 2/Jizhen 1/Malus robusta,Tianhong 2/Jizhen 2/Malus robusta were used as materials to study the effects of four buried depths(0,10,20,30 cm)of SH40,Jizhen 1 and Jizhen 2 interstocks on tree growth and fruit quality of apple.The results showed that tree height,stem diameter,branch spread,main branch number,new branch length of peripheral shoots and total branch number of SH40,Jizhen 1 and Jizhen 2 interstocks increased generally with the in⁃crease of buried depth.The fruit longitudinal diameter,soluble solid content and solid⁃acid ratio of SH40 at 10 and 20⁃cm buried depth were significantly higher than those of the other treatments,and the malic acid content at 20⁃cm depth was significantly lower than that at 30⁃cm detph.The single fruit weight,fruit longitudinal di⁃ameter and solid⁃acid ratio of Jizhen 1 and Jizhen 2 at 20⁃cm depth were significantly higher than those of the other treatments.Comprehensive analysis showed that the appropriate buried depth for the three interstock vari⁃eties was 10~20 cm for SH40,and 20 cm for Jizhen 1 and Jizhen 2,respectively.
