來看看2016美國專家的報告 https://repository.arizona.edu/bitstream/handle/10150/625410/az1706-2016.pdf 節錄關於樹洞處裡的這一段: 6. Merchant (2016) offers tips on eliminating tree-hole breeding sites: Do not fill tree holes with concrete, gravel or sand. Gravel and sand may hold water in the tree and promote decay. Gravel and concrete pose a real safety hazard for arborists or tree owners if the tree eventually has to be cut down. Drilling drain holes to keep water from accumulating is no longer recommended, as it may open the tree up to infection. Not all tree cavities need to be filled. However, if a tree hole is retaining water, expanding foam may be a good solution. Use a foam with a lower expansion ratio, and inject the foam slowly to protect the tree. It is not necessary to clean out decay from the cavity before filling with polyurethane foam (e.g., Great Stuff ProTM Gaps & Cracks Foam, Foam & Fill® Expanding Poly Sealant, or similar product). 實踐大學建築研究所學生莊傑任護樹專家? 呵呵~ 到處都是專家... -- No Snowflake in an avalanche ever feels responsible. -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 60.248.164.121 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Gossiping/M.1564548257.A.37A.html
