摘要
本试验试材为三年生‘春蕾’桃树,在新梢生长旺盛期叶面喷施PP_(333)。结果表明:PP_(333)能够抑制新梢生长,控制树冠扩大,缩短节间长度,增加早期新梢萌发量。从而起到了化学修剪的效果。
Folioge application of paclobutrazol(PP_(333))was made to 3-year-old cultivar 'Spring Bud'peach trees at strong-growing stage. The result indicated that PP_(333) could inhibit shoot growth, control the spread of the canopy, shorten internode length and increase the sprouting of initial shoot, As a result, the effect of chemical pruning was gained by the treatment.
