樹木清創治療外科手術之研發應用
Tree debridement surgery surgery research and development application
摘要
景觀樹木若遭受較嚴重或長期的病蟲障害時，其器官組織構造會顯現：樹洞傷口、腐朽殘缺…等各類型不良症狀，以致生長勢衰弱而無法恢復，最終亦會導致樹木死亡。若以傳統常見的防治方法進行醫護亦難以徹底根治病源時，此時則可評估使用「樹木清創治療外科手術（Trees debridement surgery）TDS.」進行醫治保護。樹木外科手術之應用在國內外的各方專家學者及團體組織均有許多不同的看法。這些觀點的歧異將以：文獻回顧法（Literature research）、探索性研究（Exploratory research method）、觀察研究法（Observation Survey），進行相關內容的探討與研究。經文獻回顧得知：260年前即有樹木外科手術、1993年台灣始見樹木外科手術的應用、樹木外科手術的成效有正反兩面的經驗與意見、樹木外科手術的定義雖相似但其作法相異、現今已有改良式的樹木清創治療外科手術可以有效的應用治療。根據本研究結果分析結論如下：1、傷口應避免有妨礙水分蒸發的物料封住密閉，才不會造成傷口內部濕度提高而加速腐朽潰爛。2、外科手術不可刮除樹木的防禦壁，以抵抗病原菌的繼續侵蝕與腐朽危害。3、外科手術不可以阻擋樹木傷口的癒合，也應該改善樹木力學結構上的缺陷，故應進行「人工木質部修造術」以改善樹木力學結構上的缺陷。4、外科手術不可封閉傷口，即能避免樹木傷口內部缺氧及產生酒精等有毒物質。

When the landscape trees suffer from serious or long-term nutritional disorders or pests and diseases, their organ structure will show various symptoms such as tree hole wounds, decay, incomplete, etc, causing tree growth retarded, unable restored and ultimately leading to death. If it is difficult to cure the plant disease with traditional methods of prevention and treatment, the use of ＂Trees debridement surgery (TDS)＂ may be evaluated as another method for protection. Different opinions of the application of tree surgery come from various experts and scholars of domestic, foreign or group organizations. The disagreement of these viewpoints will be categorized as Literature research, Exploratory research method, and Observation survey. From the Literature research, we learned that: Tree surgery was known 260 years ago. In 1993, the application of tree surgery was first seen in Taiwan, and there were many positive and negative experiences, and opinions on the effectiveness of tree surgery. The definition of tree surgery is similar but its practice is different. Modified TDS can be applied effectively. Based on the results of this study, the conclusions are as follows: 1. The wounds should avoid using sealing materials that will block the moisture and evaporation, so as not to cause the internal humidity of the wound and accelerate the decay and ulceration. 2. The defensive walls of trees should not be scratched by surgery to resist the continued erosion and decay of pathogen. 3. Surgery should not block the healing of tree wounds. To improve the mechanical structural defects of the trees, therefore, the ＂artificial xylem repair＂ are suggested to perform. 4. To avoid internal oxygen deficiency, alcohol and other toxic substances production in the tree, close the wound after surgery is not recommended.
