会员们:

本分会长在 2012中国园林领袖会议里, 展出过两场的 "树木修剪示范", 受到了一致好评, 详情可见附页。

修剪是树艺学当中一门非常重要的课题, 是所有 "执业树艺师" 必须掌握的知识。 对很多大树老树而言, 修剪往往是唯一可行的护养技术和减免风险的方法, 所以正当修剪对树木管理尤为重要。 修剪的理论看上去好像很简单, 但在现场操作起来, 许多未能预见的问题经常都会出现。 比方说, 切下去才看到枝条里面有腐烂、层裂或其他毛病, 哪还该再切多少, 才不会影响树体的结构和健康, 这动作会改变日后树体对周边的公众安全吗? 多过及年, 树体又将会变成怎样样的发展?

树木修剪其实就好像人体手术一样, 必须先经过专业检查和监定以后, 厘定修剪方案, 再由合资格的树艺师监督进行, 进行的人又以采用攀树师最为理想。 树木修剪涉及树艺学里面的生物学、结构学、病虫学和法律责任, 乱剪的树木日后会变成乱长, 最终更可能变成 "不定时炸弹", 为害社会。 在中国地区, 目前去讲 "树木修剪理论" 的人很多, 但当中又有多少个敢爬到树上, 使用电油锯把枝条运用溜缆技术安全的切下来? 又有多少个能指揮攀树师在树上的工作? 如果自己只会光讲而不会做, 这又能有说服力吗?

树木从生产、种植、护养到检查,都要涉及修剪。 换句话说, 不懂得正当修剪的话, 到头来也就得不到优质树木种植。 哪所谓 "优质树木种植", 就是指既安全, 又能提供种种好处的城区树木种植。 坊间说的所谓 "好看" 的树木设计, 也必须要照顾到公众安全, 不然的话再 "好看" 又有啥用? 其实所谓 "好看", 也需要与人家比较。 咱们目前的城区树木能与西方国家的来较量吗? 不能的话, 哪咱们的到底 "好" 在那里, 也为什么不能比较啊?

但愿树艺学和树艺行业能尽快的在中华地区发展起来, 造福社会。

谨此致意!

Dear Station Members,

The Station Manager (SM) gave a Structural Pruning demonstration at the 2012 China Green Leaders Forum & the event was widely publicized on national newspapers in China as per attached. The SM is known as the "Founder of the Arborist Profession" in the China media nowadays. This is an honour & would help to develop the Arborist Profession there against all odds.

If there is anything that the China Tree Care Industry would miss out most, the SM would call it on pruning than anything else. Topping is a common & acceptable practice all over China, & it is taught specifically as a skill of art in many academic institutions. This includes every university in China. The tradition is deep rooted & buried.

When the SM talked about pruning in several "Landscape Bureaus" in China in the past, he was mostly met with suspicion & doubt. The "tree experts" there would insist on what they were taught & what they were practicing, as the one & only method. To them, Target Pruning would be a waste of time, & the tree would not "look good" afterwards. Flush Cut is preferred because it does not leave a bulge at the wound, & it is thought that Topping would generate more sprouting to show the true vigour & "good health" of the tree. The SM kept seeing what he had seen in HK of 10 years ago, & the word would mostly come out from landscape designers & maintenance parties in China.

No doubt China has become the second economy in the world & has achieved many technical advances in the past 30 years. However, there are hardly any mature trees of larger than 1 m diameter left in their 600+ cities. The SM wonders whether bad pruning has something to do with it. He was told by the press that there is at least one person getting killed by tree failure in Beijing alone every year, & the incidence would usually be played down to avoid public attention. Having the SM there to bring up an occasional voice to speak for the trees, would hardly change a thing.

Anyway, somebody has to do the work, or China will take a long time to get good trees. At his age, the SM has no more to lose or fear, & he is an expert China Hand. ISA HK/China will find a way to rally support for proper pruning for the benefits of China trees.

Our mission will continue.

best regards,

ISA HK/China --- 2012 China Green Leaders Forum 2012 中国园林領袖年会







国内朋友请查閱 "百度博客 --- 国际树木学会" (http://hi.baidu.com/%B9%FA%BC%CA%CA%F7%C4%BE%D1%A7%BB%E1/blog  )   以取得其他文章。本分会的发表文章都已放弃版权, 任何人都可以自由转载作为教育目的, 但不能作为商业目的盈利。 任何人仕都可以申请免費加入本分会, 本分会员名单从不公开, 有意者请将真实姓名、年龄、单位、职衔、最高学历、电邮和手机号传真到 +852-2679-5338 便可. 如有查询, 请电邮至 egc@netvigator.com  。本分会的一切发表内容, 谨供参考。


会员们:

本分会长有幸获邀参加了由中国花卉报和其他国家级单位主办的 "2012年中国园林领袖年会", 并被安排了在讲座发言和现场示范多次, 给参会者留下了深刻的印象。

从9月19日下午5时抵步后, 本分会长晚上7时就开始参加了由全国苗木生产大户出席的苗木发展前瞻研讨会, 分享了他个人对未来国内苗木生产与销售的意见, 供参会者作为参考。 在9月20日上午, 本分会长提供了 "国际通行的行道树生产标准" 的讲座, 现场数百听众反应良好, 而且很多都是第一次与国际树艺知识作出接触, 感觉新奇讶意。

同日的下午2点, 大会在公众地方安排了一场 "树木修剪和大树风险评估" 示范, 刻意的弄来两课生长差异的小树来作表演。 事前并未有看过示范苗木的本分会长手起刀落的示范了 "撕皮切"、"错切" 和 "三刀法" 等的切法, 把原来生成一团的两棵小苗, 分别建立了 "中央主干"、"活冠比"、"螺旋分干" 和 "强接枝" 的扰势树体, 嬴得了全场百多观众的热烈掌声。 接著下来的 "大树风险评估" 表演, 是就地取材的利用马路旁边的行道树作示范对象。 分会长首先让观众们先道出他们所能看得出的树体缺陷, 然后再给每个意见提出了科学论证, 之后再分享了国际方面在此等评估的惯用手法和理论; 如此友善的交流态度和专业精神, 再一次博得了全场掌声。

当在现场示范修剪和评估的同时, 会场内正在举办 "理事单位年会"。 为了让参会理事们没有错过观赏树木修剪的机会, 本分会长当仁不让的再次在众理事专家面前, 把另一课长得乱作一团的树木样本, 使用国际修剪技术把它的树体结构重新建立起来, 令参观者惊叹不已。

在是次参会以后, 本分会长深深感受到 "树艺行业" 这门科学在中国土地上建立起来的重要性和逼切性。 树艺知识可以为国家的绿化事业省很多钱 (优质树木设计种植), 创造庞大就业机会 (市内树木风险评估), 把农闲的劳动力释放出来 (冬季修剪移植), 为读书不成的年青人创造就业机会 (成为攀树师), 好处实在太多了。

本分会愿意倾全分会之力, 去协助所有热心单位去举办第一届的 "全国树艺知识研讨会", 当中只须一天理论讲座, 加一天攀树修剪示范就够了, 只要找到合适的场地、大树和参会者便行。 我方可以派出本地区最好的树艺师和世界级的攀树师来演讲示范, 相信必然引起广大兴趣。

树艺行业对国家、民族和社会都是有益有利, 但愿它能早日在我中华大地里遍地开花吧 !

谨此致意!

Dear Station Members,

It is the pleasure & honour of the Station Manager (SM) to be invited to speak & demonstrate at the 2012 China Green Leaders Forum (CGLF). This Forum is the biggest & most influential in China, & has gathered all recognized personnel from plant production, design, landscape construction to academic research to meet once a year, to discuss the latest development. The attending VIPs are on an invitation basis, & the SM has been given the honour of being the Guest Speaker for the 2 full days while he was there. Please see the attached photos for the various events.

According to the original planning, the SM was there to talk for an hour in the morning session of Sep 20, & then to conduct a site demonstration for tree pruning & tree inspection only. Upon his arrival at 5 pm on Sep 19, the SM was told that the Forum participants would like to see & hear from more of him. Then in total, the SM spoke at the China Nursery Trade Development Seminar in the evening of Sep 19, delivered a Tree Standards seminar at the Forum, conducted a pruning & tree inspection in the afternoon of Sep 20, spoke & demonstrated the second time tree pruning at the CGLF Board Meeting that immediately followed, & then attended the Guest of Honour Dinner in the same evening. Even at breakfast before his departure on Sep 21, the SM was still crowded by the participants for many many questions. Every minute of his presence was desperately wanted.

The success of the SM on this trip can be accounted for by his fluent Mandarin & profound knowledge in Arboriculture, from tree production to design, installation, maintenance, inspection, protection & consultation. He can practically answer any question thrown at him on tree care in China. The SM is currently the highest qualified Arborist in Asia & is an ethnic Chinese. He has worked widely in our territory since 1984. This helps very much. Although such are his merits but, the SM is already approaching the retiring age. It is very important that our second generation of Arborists can soon come & take over on our course. It has been the continuous task of ISA HK/China to train up our younger generation to maintain the steam on the Arborist Profession. It may take some time to train up leaders like the SM, but Rome was not built in a day. We must insist.

The Chinese Authorities are pragmatic administrations not bound by any colonial past to accept what is good for them in their greenery development. Practices in China are very different from HK. HK will not be the model for China in developing the Arborist Profession. Our brothers up north are intelligent enough to make the correct decision. Cultural & historical sentiments bear an important part in this development. Commercial interest is another consideration. There are practically millions of "Tree Experts" working everywhere in China. To win their hearts & gain their support would require great skills & eloquence among them.

ISA HK/China has been discussing with CGN to hold the first regional conference for Modern Tree Care in China . The response has been positive, although running such a new venture there would require to overcome many hurdles. Protectionism is still strong in China among the traditional practitioners. The academics have their own knowledge & thinking. It will take great efforts to win an event as such.

ISA HK/China will relentlessly promote the Arborist Profession & ISA in our territory. This is our objective & nothing is going stop us from now.

best regards,
