普通樹根不可以做沉木,沉木是質地較硬的樹木,枯死后經自然的炭化而成的,密度要比普通木頭高出許多,因此是可以沉入水中的,而普通的樹根密度不夠,放入水中不會下沉,且在水中浸泡容易腐爛,是不能作為沉木去使用的。

  沉木的介紹

  沉木又叫流木,是一種質地較硬的樹木,密度比一般的木材高出許多,因此可以沉入水中,非常適合作為水草造景時的材料。

  選擇沉木時要留意沉木碳化的情況,由于沉木是要長期置于造景缸中,碳化的程度就不可不注意,若沉木中的木質素尚未完全分解,侵入水中一段時間后,木質素就會在水中分解成單寧和腐殖酸,會影響造景缸的視線,在選擇時要小心避免。

  上等沉木因長期泡于溫濕環境內,就算是其內部,質疏部分也會腐爛一空,所以敲擊上去,應發出空空的聲音,而在干土或半***的沙土中風化的腐木,外形雖難以區分,但敲擊上去是發“梆梆的聲音,在購買時,都可聽其聽而辨真偽。
