大青杨是东北林区两种杨树的统称,它分为两种:一种叫大青杨(Populus ussuriensisKom.),另一种叫香杨(P. Koreana Rehd.)。我们现在介绍的大青杨包括以上两种,尽管它们的形态有一定的分别(可参阅《东北木本植物图志》),但它们的木材性质和用途以及它们的生物学特性和林学特性是极相似的。大青杨是东北原始林区特别是红松老林中个头最大的树种。一般树高达30多米,胸径达2米,所以叫它大青杨。过去因为它又粗又大砍不倒运不出,所以现在几抱粗的大青杨在林区中仍可以经常看到。
Populus euphratica is a collective term for two poplar species in the northeastern region. It is divided into two species: Populus ussuriensis Kom. And P. Koreana Rehd. The Populus euphratica we are introducing now includes both of the above, although their morphologies are somewhat different (see Northeastern Woody Map), their wood properties and uses, as well as their biological and forest characteristics Very similar. Populus is the northeast virgin forest, especially the largest pine trees in the largest tree species. General tree up to more than 30 meters, breast diameter of 2 meters, so call it Poplar. In the past, because it was thick and choppy, it could not be shipped out, so now the big blooms popping around in the forest can still be seen frequently.
