[Objective] To study the effect of tree shape on tree growth and fruit characteristics of Annona squamosa.[Method]In this study, shoot growth, leaf qualities and fruit characteristics of four kinds of tree shape (trellis Y font system, double-layer central leader cross shape, single-layer central leader shape, natural round head shape ) in A.squamosa were investigated.[Result] The natural round head shape im-proved shoot growth compared with the rest tree shapes, the trellis Y font system and the natural round head shape both improved fruit size and content of soluble solids compared with the double-layer central leader cross shape and the single-layer central leader shape.The trellis Y font system and the natural round head shape would be advised for applying and extensoning of high yield and good quality tree shape in A.squa-mosa, and the natural round head shape is suitable for extensive cultivation orchard and the trellis Y font system is appropriate for standared or-chard.[Conclusion] This study can provide references for applying and extensoning of high yield and good quality tree shape in A.squamosa.%[目的]调查不同树形对番荔枝树体生长情况和果实性状的影响.[方法]比较番荔枝4种树形(架式Y字形、主干十字双层形、主干单层形和自然圆头形)枝梢生长、叶片质量、果实性状.[结果]自然圆头形的枝梢生长较其他3种树形旺盛,架式Y字形和自然圆头形在果实大小和可溶性固形物含量方面均高于主干单层形和主干十字双层形,架式Y字形和自然圆头形可以作为番荔枝高产优质栽培树形的应用与推广,对于管理粗放的果园采用自然圆头形即可,对于标准化生产果园可采用架式Y字形.[结论]该研究可为番荔枝高产优质栽培树形的应用和推广提供参考.
