沧浪亭古树树体现状和症状及保护技术措施研究

Research on Current Situation,Symptoms and Protection Technical Measures of Ancient Trees in Surging Waves Pavilion

调研了沧浪亭现存古树的生长现状与病状,得知沧浪亭现有古树14株,分别属于9科10属,树龄为120～260年。沧浪亭古树总体得到了较好的保护,长势良好的古树9株,占64.29%,分别为银杏、柏树、罗汉松、榉树、香樟、瓜子黄杨、紫藤;需重点保护的古树5株,占35.71%,分别为女贞、桂花、枫杨,具体病状表现为树干腐蚀中空和洞穴状。基于需重点保护的5株古树的病状,笔者提出女贞和桂花的保护措施为:①对主干上穴口进行封实处理,②清除主干表层已腐烂木质并消毒、涂抹防腐蚀保护剂,③填补树干洞穴;枫杨的保护措施为:①清理洞穴内部、内壁,②对树干进行防腐消毒处理,③涂抹防腐保护剂。

The paper had studied growth situation and disease symptoms of ancient trees in Surging Waves Pavilion.There were 14 ancient trees belonging to 10 genera of 9 families,with tree age of 120-260 years.These trees had been well protected generally.There were 9 ancient trees growing well,occupying 64.29%,which were Ginkgo biloba,Cupressus funebris Endl.,Podocarpus macrophyllus,Zelkova schneideriana Hand.-Mazz.,Cinnamomum camphora（L.） Presl,Buxus sinica,and Wisteria sinensis Sweet.There were 5 ancient trees needed to be protected preferentially,occupying 35.71%,including Ligustrum lucidum,Osmanthus fragrans and Pterocarya stenoptera.The disease symptoms were trunk rot and hollow structure.Based on these symptoms,the paper had proposed protective measures for Ligustrum lucidum and Osmanthus fragrans：① enclosing eroding holes on the trunk;② clearing up eroded wood on the surface of trunk,disinfecting and applying anti-corrosion protectants;③ filling eroded holes of the trunk.Protective measures for Pterocarya stenoptera included：① clearing up the inner part and intine;② eliminating pernicious influence for corrosion prevention;③ applying anti-corrosion protectants.
