刺槐(Robimia pseudoacaciaLinu),过去称洋槐,属蝶形花科刺槐属,落叶乔木。刺槐原产北美,我国于清朝末年曾首先引入山东青岛,以后相继在各地栽培,现已几乎遍及全国。刺槐的垂直分布,在河北、山东、山西海拔1200—1400米以下,甘肃可达2000米。刺槐属温带树种,抗寒力较差。所以,在分布范围内,它的生长势往往随着海拔的升高却相应地降低。而在长江以南,又因气候湿热,也不适宜生长。最适宜刺槐生长地区是在黄河中、下游、山东、辽东半岛及淮河流域。刺槐用途广泛,是很好的速生用材树种,具有材质坚硬,纹理细致,富有弹性,
Locust (Robimia pseudoacaciaLinu), used to call acacia, Papilionaceae genus Robinia, deciduous trees. Locust origin North America, China in the late Qing Dynasty first introduced Qingdao, Shandong Province, after one after another in all parts of cultivation, is now almost all over the country. Robinia pseudoacacia vertical distribution, in Hebei, Shandong, Shanxi 1200-1400 meters below sea level, up to 2000 meters in Gansu. Robinia is a temperate tree species, poor cold resistance. Therefore, in the distribution range, its growth potential tends to decrease correspondingly with the elevation. In the south of the Yangtze River, it is not suitable for growth because of hot and humid climate. The most suitable locust growth area is in the middle and lower reaches of the Yellow River, Shandong, Liaodong Peninsula and the Huaihe River. Robinia paniculata widely used, is a good species of fast-growing timber, with hard material, texture and meticulous, flexible,
