1 树形结构及其培养 桃树常用树形有杯状形、改良杯状形、变则主干形、自然开心形和两主枝倒“人”字形等。经生产应用证明,以后两种最适合桃树的特性,效果最好。1.1 自然开心形 优点是骨架牢固,树冠大而不空,枝条密而不挤,既不挡风遮光,又不易出现下部光秃,生长旺盛,丰产性好,更新容易。树体结构:主干高40cm,树高2.5-3.0m,主枝3～4个,侧枝9～12个,适用于3m×4m或3.5m×4m的株行距。
A tree structure and its cultivation Peach tree commonly used cup-shaped, cup-shaped improvement, change the main trunk-shaped, natural happy heart and two main branches inverted “human” glyphs and so on. Proved by the production application, after the two most suitable peach characteristics, the best. 1.1 The natural happy shape has the advantage of solid skeleton, large but not empty canopy, dense branches and not crowded, neither the wind and shade, but also prone to the lower part of the bare, vigorous growth, high yield, easy to update. Tree structure: trunk height 40cm, tree height 2.5-3.0m, 3 to 4 main branches, 9 to 12 branches, suitable for 3m × 4m or 3.5m × 4m of the line spacing.
