摘要
在渭北高原,以盛果末期苹果树为研究对象,以长放修剪为对照,测定了更新修剪对腐烂病的发病率、病情指数和树体生长及产量的影响。结果表明:更新修剪可极显著降低腐烂病的发病率及病情指数,极显著缩小树冠体积,极显著提高单果质量和果实产量。盛果末期苹果树应积极采用更新修剪。
Compared with long-branch pruning in Weibei Plateau,Shaanxi Province, the effects of renewal pruning on the incidence and index of valsa canker, and the growth and yields of apple tree in final full productive stage were determined. The results showed that renewal pruning significantly decreased the incidence and index of valsa canker, significantly shrunk crown volume, and significantly increased fruit weigh and fruit yields. Weibei Plateau should actively apply renewal pruning to apple tree in final full productive stage.
