摘要
对老弱杏树冬、夏两次修剪，剪除枝量的１／４～１／３，取得恢复树势、提高果实品质的良好效果。修剪树各类枝中，中、长梢比例增加，枝梢生长势强，新梢生长量增加，单叶面积增加，果实纵径、横径和单果重增加，提高了果实品质。
Studies from 1989 to
1992 with 29─40-yr-old trees,var.Niudu and Erhong,grown in anapricot orchard in Dalong Village,
Daming County,Hebei Province showed that medium/longshoot ratio,shoot vigour and
growth,single leaf area,fruit site and weight,and fruit qualitywere inreased by thinning off 1/4─1/3
growth volume of whole tree in winter and cutting offthe diseased, pest-injured and overlapping
growths in summer.
