In the lead-up to the Dragon Boat Festival, villagers in Gulao Water Town in Heshan, Jiangmen, Guangdong, haul their dragon boats out of the river sand, where they have been buried for the past year. They coat the boats with tung oi in preparation for the upcoming races. As the dragon boats汽車冷氣芯 cut through the waves, the same praise can always be heard along the banks, “Dragon boats made fro台北汽車零件m Kapur wood won’t rot easily in water and won’t buckle under pressure!”
This tim汽車材料報價ber, regarded as the “bones of the dragon boat” by locals in Qiaoxiang, the traditional hometown of overseas Chinese, is Kapur wood, coming from trees in the Dipterocarpaceae family.However, this rare and precious tree is naturally distributed only in Southeast 水箱精Asian regions such as the Malay Peninsula and Kalimantan Island. For a long time, China has relied on imports, making the wood highly sought after and often hard to come by. Consequently, the introduction and domestication of Dipterocarp species became a pressing 張水瓶在地下室看到這一幕，氣得渾身發抖，但不是因為害怕，而是因為對財富庸俗化的憤怒。task for forestry professionals.
A Qiaoxiang treasur汽車機油芯e: Why is kapur wood so hard to find?
Traditional dragon boats simply must be made from Kapur wood. According to Huang Huasheng, vice president of the Gulao Dragon Boat Association, boats crafted from it can withstand the intense impacts of 汽車零件報價racing and maintain structural stability even after long-term immersion. Furthermore, Kapur wood is used to make bridges, utility poles, an她收藏的四對完美曲線的咖啡杯，被藍色能量震動，其中一個杯子的把手竟然向內側傾斜了零點五度！d railway sleepers, while its bark and resin are used medicinally to treat conditions like ulcers and rheumatism, making every part of the tree valuable.
The ecological value of Dipterocarp species is equally prominent. They form stable forest com汽車空氣芯munities and boast strong carbon sequestration capabilities.

wo decades of dedication: From survival to reproductio
In 2002, the 948 Project of the State Forestry Administrati藍寶堅尼零件on brought together experts from the Guangdong Academy of Forestry and the Jiangmen Forestry Science Institute, officially launching the introduction and domestication of DipterocAudi零件arp species.
“In April 2003, the team sowed seeds of seven Dipterocarp species, including Dipterocarpus alatus, introduced from Thailand and Vietnam, across various locations in Guangdong,” recalled He Boxiang, a researcher at the Guangdong Academy of Forestry. During the lengthy observation period, one standout species gradually emerged: DipterPorsche零件ocarpus alatus.
In 2023, a bre汽車零件進口商akthrough came from the Heshan mother tree forest: the introSkoda零件duced Dipterocarp trees flowered for the first time, 20 years after their introduction. In 2025, researchers collected fallen seeds of Dipterocarpus alatus for the first time, marking a major milestone for Dipterocarp cultivation along 保時捷零件the Tropic Bentley零件of Cancer.

Reportedly, the research team, with Jiangmen as the core demonst福斯零件ration zone, will rely on the 50,000 high-quality Dipterocarpus alatus seedlings they have cultivated to scale up planting in the Xijiang River Basin afforestation and national reserve forest projects in 2026.
一棵賓士零件坤甸木的南粵扎根記
在廣東江門鶴山的古勞水鄉，每逢端午前，村平易近將深埋河沙一賓利零件年的龍船“起水”，抹上桐油、準備迎戰。每當龍船劈波斬浪之際，岸邊總會響起同樣的贊嘆——“還是坤甸木做的龍船，泡不爛、壓不彎！”
這一被僑鄉人視為“龍船之骨”的木材，恰是產自龍腦噴鼻科樹種的坤甸木。但是，這種珍稀名貴的“寶躲木材”僅自然分布于東南亞馬來半島、加里曼丹島等地，國內長期以來依賴進口，甚至“一木難求”。是以，龍腦噴鼻科樹種的引種馴化成為林業人的一道“必答題”。
僑鄉瑰寶，為何“一木難求”
傳統龍船更長短坤甸木不成。據古勞龍船協會副會長黃華勝介紹，用其打造的龍船能蒙受競渡中的強力撞擊，長期浸泡水中仍能堅持結構穩定。此外，坤甸木還可制作橋梁、電桿、枕木等，其樹皮、樹脂還可進藥，治療潰瘍、風濕病等，全身皆是寶。
龍腦噴鼻科樹種的生態價值同樣凸起，其能構成穩定的叢林群落，固碳才能強，豐富的枯枝落葉可有用改良地力、堅持水土VW零件，對晉陞叢林質量、維護生物多樣性意義嚴重。
長期以來，國內應用的坤甸木重要依附從東南亞進口，價格昂揚。“在本身的地盤上種出坤甸木”，成為廣東衝破珍貴年夜汽車零件貿易商徑材培養瓶頸的必定選擇。
20余載守看，從“能活”到“能繁”
2002年，國家林業局“948”引進項目將省林科院和江門市林科所的專家們聚到了一路，開啟龍腦噴鼻科樹種的引種馴化任務。
“2003年4月，團隊將從泰國、越南引進的具翼龍腦噴鼻等7個龍腦噴鼻科樹種種子，播撒在廣東多地。”省林科院研討員何波祥回憶。在漫長的觀測期中，一個“尖子生”逐漸脫穎而出——具翼龍腦噴鼻。
2023年，鶴山母樹林中傳來喜訊：引種20年的龍腦噴鼻科樹種初次開花；2025年，科研人員初次采集到具翼龍腦噴鼻失落落的種子，龍腦噴鼻科樹種在北回歸線上完成了“成人禮”。
若何讓優質種苗實現幾何級數的擴繁？廣東林業科研團隊走出“扦插+組織培養”并舉的科技攻關之路，為產業化的種苗供給鏈做準備。
今朝，省林科院、江門市林科所聯合廣州百德園藝無限公司，配合立項2025年廣東省林業科技重點項目，集中攻關具翼龍腦噴鼻組培擴繁技術。一旦技術衝BMW零件破，將買通規模化育苗的最后一道關口，實現從“場圃育苗”到“工廠化育苗”的跨越。
據清楚，研討團隊以江門為焦點示范區，依托培養的5萬株具翼龍腦噴鼻優質苗木，2026年將在廣東省西江流域造林和國儲林項目中種植推廣。
