《小岛国 大发现》第二集 ❤️❤️❤️
樹洞為何不能發泡劑填洞?看看日本樹木醫劉東啟老師的團隊怎麼說。
發泡劑填充阻礙傷口癒合,而且會導致樹洞嚴重腐朽。
英國、美國和日本都有提出相同的警告。
【淺談樹木外科手術】借鏡歐美經驗
1.樹木外科手術是什麼?
1990年以前,歐美曾經大規模進行樹木外科手術。方法是清除樹木腐朽部位,填入防腐藥劑、水泥、瀝青或人造泡棉等填充物質,並在外層以塑膠軟墊覆蓋的一種企圖使樹木恢復健康的醫療行為。
2.樹木外科手術的禁止
經多年的實驗證實,樹木外科手術並無法阻止樹木持續腐朽潰爛,對於樹木恢復健康勢並不幫助。因此,在歐美國家的準則中,已經禁止使用外科手術的方式治療樹木 :
(1)「美國國家標準協會(ANSI)」制定的A300準則-2008年(註1)中規定,不得將傷口處理藥劑填充與覆蓋在傷口表面或是修剪傷口上;不得使用會損害到樹體組織的傷口處理藥劑;修整樹木傷口邊緣時,只能去除壞死或損傷的組織。
(2)「英國標準學會」制定的BS3998準則-2010年(註2)中規定,樹木的空洞、傷口,填充空洞並不能改善樹木力學上的支撐力,而且可能會抑制癒傷材料(窗框材)的形成。柱狀的癒傷木(窗框材)才能夠讓樹木的空洞開口邊緣具有力學的支持力。且不可割破木材組織,因為留下的傷口可能會破壞樹木對抗木材腐朽菌產生的「防禦層」。
(3)「最新‧樹木医の手引き,2006」第11章第2節(註3)提到「美國國家標準協會(ANSI)」A300準則在1995年外科手術會影響樹木傷口的癒合與破壞樹木對抗腐朽菌的防禦壁。「英國標準學會」制定的BS3998準則在1989年(註4)就不建議填充空洞。
p.s.有近代樹木醫學之父美譽的美國學者Alex Shigo博士在1985年提出了「腐朽區隔理論」(CODIT,Compartmentalization Of Decay In Trees),說明樹木自身有防禦機制,當病原菌入侵時,樹體會形成變色材與防禦壁,來抵抗病菌繼續侵蝕與腐朽。
註1:美國國家標準協會(ANSI)制定的A300修剪準則
5.4 Wound treatment傷口處理
5.4.1 Wound treatments shall not be used to cover wounds or pruning cuts, except when necessary for disease, insect, mistletoe, or sprout control, or for cosmetic reasons.
5.4.2 Wound treatments that are damaging to tree tissues shall not be used.
5.4.3 When tracing wounds, only loose, damaged tissue shall be removed.
註2: 英國標準學會制定的BS3998準則-2010年
9 Management of decay – cavities and water pockets
9.1 General
Where a tree is found to be so physically weakened, by cavity formation or other decay, that it poses an unacceptable risk to people, property or its own integrity, appropriate action should be taken to reduce the risk to an acceptable level. The management options available in such circumstances include:
• moving or modifying the target;
• tree work such as pruning (see Clause 7) or providing artificial support (see Clause 10);
• in the event of all other options being impracticable or otherwise inappropriate, felling (see Clause 12).
Additionally, cavity treatments (see 9.2) may be undertaken in order to help reduce the rate of further decay if this objective is assessed as being feasible and of significant benefit for the structural integrity of the tree. Where there is a need to deter human access to a cavity, some form of artificial closure or filling may be installed (see 9.3).
NOTE Filling cavities is not generally considered to improve the structural integrity of the surrounding wood and indeed might inhibit the development of pillar-like rolls of occluding wood, which provide natural strength at the edge of a cavity opening. A filling can also reduce the habitat value of the tree and/or hamper future inspection.
註3:最新‧樹木医の手引き,2006
付記1 アメリカの産業規格における外科 附錄1手術美國行業標準
この分野のアメリカ産業規格ANSI A300-1995では、施肥、樹体の支持、移植、雷対策など様々な規格が定められているが、枝切断の章から傷の処理に関する記述を探すと以下の通りである。
5.2.6.1 傷の処理
病気や穿孔虫、ヤドリギ、萌芽抑制か修景上の理由という特例を除き、傷口保護材や樹木用の塗布剤で枝切断部を被覆してはならない。もし傷口保護材を修景上その他の理由で使用する時は形成層に無害な物質を用い、傷表面に薄く塗布すべきである。
5.2.6.2 樹皮の傷を修復する時は、傷ついたか緩んだ樹皮だけを取り除き、生きた組織の損乱を最小限にする。
5.2.6.3 空洞は、(傷や腐朽に対する)境界反応帯を撹乱する場合は充填や(外科的な)処理をすべきでない。
付記2 イギリスの同様な規格BS3998 附錄2類似標準BS3998英國
BS3998 (1989) の中では、ANSIより細かい点まで記載されているが、空洞の充填は推薦されていない。外観上特別に必要な場合だけに行い、再点検などが容易な材料を使うとしている。殺菌剤の使用条件などではアメリカと違う内容になっている。なお、全内容で欧州での規格共通化が進められているので、近い将来、記述内容に変更があると思われる。
註4: 英國標準學會制定的BS3998準則-1989年:http://211.167.243.154:1012/file/gwbz/BS%203998-1989.PDF
17.4 Intentional filling of cavities
Filling cavities is not recommended. An exception may be where the appearance of the tree is of major importance. Fillings should be flexible, non abrasive and easily removed, e.g. urethane foam, to allow future inspection of the cavity.

【大埔鷺鳥林】事件近因可能係康文署沒有足夠專業職系人員,例如園境師,在處理市民就樹木和動物或雀鳥的投訴,未能從專業角度處理,容易造成失誤,我會建議康文署增加相關專業人員職位,避免事件再次發生。
政府在環境保育如樹木管理方面,政出多門,更可能係今次事件的深層次問題所在。漁護署、環保署、康文署、民政署、各個工務部門等等,多個部門涉及其中,就難免有互不協調的情況,政府實需梳理及重整部門之間分工權責,譬如成立樹木處,並讓專業職系人員從專業角度,更全面處理。
修樹工程公然破壞大埔鷺鳥林
Blatant destruction of Tai Po Egretry during tree pruning works
就昨日(2017年6月6日)康樂及文化事務署於受保護的大埔墟鷺鳥林進行修樹工程所造成的破壞,嘉道理農場暨植物園(本園)的野生動物拯救中心一共接收到15隻雀鳥以進行拯救和復康,當中5隻到達時已身亡,1隻因傷重而人道毀滅,9隻仍生存的正接受深切的治療及照顧,品種包括池鷺、夜鷺、小白鷺和大白鷺。
對於署方容許於鷺鳥繁殖期間在已知的受保的護鷺鳥林(也由當局註冊)進行修樹工程,本園保育人員感到震驚和憤怒。所有鳥類均受香港法例第170章《野生動物保護條例》所保護,故意干擾或傷害野生鳥類、或破壞牠的巢和蛋均屬違法。我們促請署方進行調查和跟進,讓涉及觸犯法例和疏忽行為的人員負上責任,接受紀律處分和檢控。
類似的事件不能再次發生,因此本園促請署方檢討現有修剪樹木的程序,確保有完善機制避免康文署職員或外判進行犯法行為,康文署管理層需進行足夠的監管,以確保野生動物不會因修樹工程而受到傷害。
現有9隻幼鳥於本園野生動物拯救中心接受治療,這些小生命非常脆弱,照顧上也很困難,牠們受到的外來壓力(從高處墜下、脫水、中暑和臨時斷糧)意味著牠們可能仍有一段時間處於不穩定狀態,或者沒有能力生存下去。不過,本園野生動物拯救中心團隊會盡力拯救每一隻幼鳥,讓牠們於康復後回歸大自然。

As a result of the serious damage to the protected Tai Po Market Egretry during tree pruning works undertaken by LCSD staff yesterday (6 June 2017), the Wild Animal Rescue Centre of Kadoorie Farm and Botanic Garden (KFBG) has received a total of 15 birds for rescue and rehabilitation. Among the birds, 5 were dead on arrival, 1 was euthanized due to its serious condition, and 9 remain alive and under intensive care. The rescued species include Chinese Pond Heron, Black-capped Night Heron, Little Egret and Great Egret.
Conservation staff at KFBG are shocked and outraged that the tree pruning work was planned and allowed to go ahead at a known (to the Authorities) protected breeding site for the birds in the breeding season. All birds are protected under Cap 170 of Wild Animals Protection Ordinance in Hong Kong and it is illegal to disturb or injure wild birds or destroy their nests and eggs. We hope that a full investigation will be undertaken and responsible persons held to account for what was clearly criminal and negligent behaviour. We expect to see those responsible disciplined and prosecuted under Cap 170.
It is very important that a similar event does not happen again so KFBG urges that the present procedures for such roadside pruning are reviewed to make sure that there is a mechanism that prevents LCSD staff and contractors from carrying out such criminal acts and that there is adequate supervision from LCSD management to make sure wildlife is not harmed by the tree pruning and activities.
Nine hatchling birds in are now being cared for at the KFBG Wildlife Rescue Centre. They are delicate and care can be tricky. The additional stresses they have suffered (fall from height, dehydration, heat stress and possible temporary food deprivation) may mean birds remain in a critical state for some time and not all may be strong enough to survive. However, the Rescue Team will do its best to rehabilitate the young birds and return as many as possible back to the wild.

如何讓甜柿生更多水果?富有甜柿需要修剪嗎?甜柿如何修剪?富有甜柿開花不結果,富有甜柿不開花怎麼辦?
果樹開花結果研究: 有些果農(種植柿子,蓮霧,芭樂,龍眼,荔枝,水梨,芒果,蘋果,石榴,百香果等)會用殺蟲劑,有機磷噴果樹葉來催花(有效),但是有毒素政府已明令禁止, 因此有些農民會用果樹幹環刻, 剃光頭, 蓋紗網兩個月或者灌入海水來催花,這些確實證實都有效,但以上每種方法都對果樹有不良的傷害和影響,後來有農民採用輕度修剪證明對果樹催花開花結果效果不錯,輕度修剪就是修剪掉約3分之1 果樹枝葉讓陽光能穿透整顆蓮霧到達地面。 此方法我已經採用多年證明正確修剪有自然的健康的催花效果, 建議各位網友開始做正確的修剪, 一般果樹修剪後三個月後就會開花結果,修剪的一些技巧可參考我的果樹修剪影片,每一支影片都是長時間驗證過,符合果樹生長科學有效的方法。
https://youtube.com/playlist?list=PLthpt3wMIBvd5XitudaVPmL-DpPBbHvRL
果樹修剪最佳時間點:
1. 常綠水果樹,如芭樂,蓮霧,龍眼,芒果,百香果等: 春天前2周 (1月),秋天 (9月)
2. 冬眠水果樹,如桃子,蘋果,水梨,石榴,李子,柿子等: 春天前2周 (1月)
很多網友果樹不開花結果問題,一般都是未能正確修剪或沒有修剪造成的。
庭院果樹修剪要領和技巧,富有甜柿修剪方法,果樹修剪時機,柿子何時修剪,柿子修剪後多久開花,柿子多久結果。修剪3個月後柿子開花結果,修剪7個月後柿子成熟,可採收。
柿子繁殖方法: 可用空壓法或嫁接法。柿子每年都會休眠過冬,休眠期所有葉子都脫落,修剪最佳時機為1-2月。
柿子有甜柿與澀柿兩種,甜柿可以直接食用,澀柿則需要人工脫澀後方可食用。柿子的營養素十分豐富,柿子中含糖15%,含有蛋白質1.36%,脂肪0.57%,以及含有大量的胡蘿蔔素、維生素C、葡萄糖、果糖及鈣、磷、鐵等礦物質,粗纖維等元素和多種維生素,所含維生素和糖分比一般水果高1-2倍左右。與蘋果相比,除了鋅和銅的含量蘋果高於柿子外,其他營養成分均是柿子占優。

本葡萄修剪影片展示如何正確修剪葡萄樹,並驗證3個月後開花結果,6個月後葡萄掛滿藤上,收穫滿滿!葡萄是最需要修剪的果樹,枝葉太多的話葡萄反而生很少葡萄,如果不修剪的話,葡萄很難會有好的收成,一顆葡萄的空間範圍大概就是兩個手臂張開的大小。
修剪這個葡萄基本上有兩種方法,兩種方案
1: 只保留兩根主幹
2: 保留比較多主幹
葡萄修剪時要保留一節,它會從這邊發芽長出新的枝葉出來,一長出來就開花結果
正確修剪6個月後,葡萄成熟,葡萄掛滿。
葡萄枝葉修剪要保留2條去年新生但尚未結果的枝條。
葡萄增加產量,葡萄枝葉修剪,葡萄何時修剪枝葉,如何修剪葡萄,正確葡萄修剪,有機葡萄種植。
Keep only 2 new branches grow in this year, prune all other grape fruit tree branches.
