會員們:
附上的圖片，展示了樹木工作人員正在為古樹在檢查，和鬆開看上去綁得緊緊的支撐扣，並提出了支撐的目的和鬆扣的理由。
在樹藝學來言，樹木支撐普遍有三個目的：
- 1. 對新種上的幼年樹作岀支撐，以防由於根系尚未完全開展，招致風中倒伏
- 2. 對成年/老年樹作出支撐，由於其根系受到傷害，或腐爛/收縮至某危險程度，不撐的話有可能倒伏
- 3. 大樹/老樹的枝幹在木質結構上已經變成不安全，須要支撐來防止斷落
長時間的全株支撐，通常會引起根系不開展、幹粗收窄不出現、和樹木長葉不長根的毛病，令支撐拿走之後，樹木更容易倒伏。 對幼年樹來講，長期支撐會防礙枝幹的次生長，包裹接觸的部份也會惹生病蟲害。
從附圖所見，古樹右邊的其中一條主幹，是已經被切斷切平了，傷口相信巨大。 樹上的兩個支撐點都用金屬環縛得剛好，而且接觸面見不到有墊層，不知道有否批損樹皮。 支撐只裝西面，如果吹強烈西風又不知道會怎麼樣？ 既然已冠為古樹，相信都不會再長粗，那鬆扣的真正目的在啥？ 工作人員戴上一些安全裝備來施工，可能會更好吧？
在樹藝學來講，樹木種植最好不需要支撐，樹木在大自然的億萬年生長也是如此，只是人類為了某些目的才去把它去改變了嘛。
謹此致意!

会员们:
附上的图片，展示了树木工作人员正在为古树在检查，和松开看上去绑得紧紧的支撑扣，并提出了支撑的目的和松扣的理由。
在树艺学来言，树木支撑普遍有叁个目的：
1. 对新种上的幼年树作岀支撑，以防由於根系尚未完全开展，招致风中倒伏
2. 对成年/老年树作出支撑，由於其根系受到伤害，或腐烂/收缩至某危险程度，不撑的话有可能倒伏
3. 大树/老树的枝幹在木质结构上已经变成不安全，须要支撑来防止断落
长时间的全株支撑，通常会引起根系不开展、幹粗收窄不出现、和树木长叶不长根的毛病，令支撑拿走之後，树木更容易倒伏。 对幼年树来讲，长期支撑会防碍枝幹的次生长，包裹接触的部份也会惹生病蟲害。
从附图所见，古树右边的其中一条主幹，是已经被切断切平了，伤口相信巨大。 树上的两个支撑点都用金属环缚得刚好，而且接触面见不到有垫层，不知道有否批损树皮。 支撑只装西面，如果吹强烈西风又不知道会怎麽样？ 既然已冠为古树，相信都不会再长粗，那松扣的真正目的在啥？ 工作人员戴上一些安全装备来施工，可能会更好吧？
在树艺学来讲，树木种植最好不需要支撑，树木在大自然的亿万年生长也是如此，只是人类为了某些目的才去把它去改变了嘛。

Dear Station Members,
Attached is a recent newspaper cutting in China, showing the tree workers loosening up the grips on a Veteran Tree during their regular inspection.
It is so described in the remarks on the photo that the tree was supported by metal railing & grips to avoid toppling & breakage by wind & snow. The loosening of the grips “is for preventing any chafing of the tree parts in view of the continuous growth of the Veteran Tree”, so that structural damage is not to be anticipated.
China is a place which can be advanced in many sectors of science & technology, but apparently not matching the world when it comes to tree care. In the many seminars & visits of CAA there in the past, we have a general feeling that tree care is not regarded as a necessity, & if any problem occurs, the tree is simply removed. Given a country so vast to spread the population unlike some crowded city in Asia, China has been practicing their own principles in Arboriculture with their own experts, many of whom do not understand English to join the world.
CAA has translated & published quite a number of articles on Arboriculture within China, & most were well received. However when it comes to the administrative level, hardly any international idea would be accepted, & the industry just carries on the same old way. The administrators would view any change as a menace, & updated knowledge & practices are extra burden.
Currently China is undergoing administrative storm in combating corruption. This is a time to make it even harder to try to bring in any outside ideas to the administration, as no one knows how long the same official would stay in a particular post. China may need to wait for a little while, unless the top administration has suddenly decided to call up a rapid change in tree care.
Patience is the key to work along with this Land of the Old Dragons, & who would know it better than CAA?
best regards,
