摘　　要：以2010年春季栽植的王林/SH40/八棱海棠为试材,于2011~2018年连续8年调查树体生长、枝类组成和果实产量、品质的变化。结果表明:随着树龄的增长,树体高度、冠径、树干粗度、覆盖率以及总枝量均有不同程度的增加,在栽植后前4年增长速度较快,之后通过修剪可控制树体的生长;随着树龄增长,短枝的比例逐渐增加,长枝的比例逐渐降低,在栽植后第5年树体枝类组成趋于稳定,短枝比例维持在65%以上,长枝比例维持在10%左右;随树龄的增加,产量逐年大幅度增加,在栽植后第7年进入稳产期,年产量高达49 t/hm 2左右;果实品质稳定性较好,在不同树龄间差异不显著。The apple trees of Wanglin/SH40/Malus robusta planted in spring 2010 were used to investigate the dynamic changes of tree growth,number and proportion of different branch lengths,yield and fruit quality from 2011 to 2018.The results showed that tree height,crown diameter,trunk thickness,coverage and total branches all increased differently with the increase of tree age.The growth rate was faster in the first 4 years after planting,and the growth of the tree could be controlled by pruning.With the increase of tree age,the proportion of short branches gradually increased,and the proportion of long branches gradually decreased.The composition of tree branches tended to be stable in the 5th year after planting.The proportion of short branches maintained above 65%,and the proportion of long branches maintained at approximately 10%.With the increase of tree age,the yield increased significantly year by year.The plant entered a stable period of production in the seventh year after planting,with an annual yield of about 49 t/hm 2.The fruit quality was stable,and the difference among different tree ages was not significant.
