有些无论是走势还是曲度都可称为上品的榔榆桩干,其根部却有向下渐细的缺陷。这类桩干即使树冠可以培育成功,但根部的缺陷却严重影响了桩景的观赏效果。根据本人长期以来的育桩经验,有一行之有效的办法——剖锯补缺法可以用来补救。在采掘有这种缺陷的榆桩时,其根部的须根应尽可能地多保留,这样有利于桩干早日成活定型。具体操作过程如下:①从桩干根底下锯,下锯的方向要与树顶部垂直;②锯口要与自己所选择的观赏面垂直;③所锯深度要根据根部的缺陷情况而定,一般超过缺陷位置一寸左右即可。不过,如树干较粗的应锯深些,反之,则锯浅些;④剖锯后,用木
Some of the trend or curvature can be referred to as the top-grade palm elm pile dry, but there are downward roots of the root defects. Even if the crown can be nurtured successfully, the root defects seriously affect the ornamental effect of the pile view. According to my long history of education, there is an effective way to solve this problem. In the mining of such defects Yu-piles, the root of the fibrous roots should be retained as much as possible, so that the pile stems early survival modeling. The specific operation process is as follows: ① sawing from the bottom of the pile, the direction of sawing should be perpendicular to the top of the tree; ② the kerf should be perpendicular to the viewing surface of your choice; ③ the sawing depth should be determined according to the root defects, More than an inch defect position can be. However, such as thicker trunk should be sawing deeper, on the contrary, then sawing shallow; ④ cut sawing, with wood
