摘要：為解決安徽省淮河以南降水量多的區域桃樹下半部光禿枯死，及桃栽培不適宜機械化生產的難題，提出一種高光效適宜機械化操作的桃樹新樹形，即倒“個”形新樹形。倒“個”形新樹形的桃樹中央干強而直立，無主枝、側枝，中央干上除基部著生2個調節枝組外，其余直接分生小型結果枝組;樹高2.5～3.0 m，冠徑1.5～2.0 m，主干高度50～70 cm。該樹形能促進桃樹早產、豐產、穩產，延長桃樹盛果期樹齡，提高果實商品率和優質果率。

關鍵詞：桃;樹形;倒“個”形;整形修剪

Abstract： In order to solve the issues of baldness and death in the lower half of peach trees in the area with abundant rainfall in the south of Huaihe River in Anhui Province and trees unsuitable for mechanized production in peach cultivation， a new peach tree shape with high light efficiency and suitable for mechanized operation was proposed， which was inverted‘Ge’ shape （Chinese character）. The central trunk of peach tree was strong and upright without main and lateral branches， except for two regulating branch groups at the base， all the others were directly divided into small fruiting branch groups. The tree height was 2.5 to 3.0 m， the crown diameter was 1.5 to 2.0 m， and the trunk height was 50 to 70 cm. The application of this tree shape could promote the premature， high and stable yield of peach trees， prolong the tree age of peach trees in full fruit period， and could improve the commodity rate and high-quality fruit rate of fruits.
