1997年笔者在邢台县南石门乡周公村果园搞试验发现,有相当一部分果农在果园施肥过程中,存在着施肥部位不当的现象,大多数离树干较近,不仅降低了肥料的利用率,又伤了不少大根。因此,果树施肥部位的确定至关重要。 果树对肥料的吸收,主要靠根系中的根毛来完成,在根毛集中分布区施肥,可以最大限度提高肥料利用率。 根与枝、干的维管束是相互沟通的,使地下部与地上部保持着密 In 1997, the author conducted experiments in the orchards of Zhougongcun Village, Nan Shi Shimen Township, Xingtai County. It was found that a considerable number of farmers in the orchard fertilization process, there are improper fertilization sites, most of them close to the trunk, not only reduces fertilizer utilization, and Injured a lot of big roots. Therefore, fruit tree fertilization site is crucial.

Roots and branches, dry vascular bundle is to communicate with each other, so that the underground and the ground to keep the dense
