      介绍: 晚饭后,嘟拉一家去公园散步,路上一棵大树吸引了嘟拉的注意。
      嘟拉:“爸爸,那是什么树呀,好高大。”
      嘟拉爸爸:“那是槐树,这种树的树型是很高大,它有15~25米高,你看它灰褐色的树皮,上面还有着纵裂纹,长圆形的叶子前面渐渐变尖,下面是灰白色并带有一些小柔毛。花萼是钟状的,花冠是白色或淡黄色,花瓣是淡黄色。槐树有短柄和紫色脉纹,它的荚果成串珠状,种子排列比较紧密,是卵球形,淡黄绿色,干后就成了黑褐色。”
      嘟拉:“呀,这么茂盛的叶子,白天坐在树下就不怕太阳晒啦。”
      嘟拉妈妈:“是的呢,槐树自古以来就是我国绿化、观赏树种之一。它喜欢阳光,耐烟尘,能适应城市街道环境,病虫害也不多,寿命比较长。在我国各大地区都有普遍栽培呢。”
      嘟拉:“它的树干这么结实,应该用处也不少吧。”
      嘟拉爸爸:“恩,槐树的木材富有弹性,又耐水湿。所以供建筑、船舶、枕木、及雕刻等使用都是很好的。它还有很多可以用到的地方,像种仁含淀粉,可以酿酒或作糊料、饲料;种子榨油供工业用;槐花可作黄色染料;花蕾可用来做清凉性收敛止血药等等。”
      嘟拉:“哇,还有这么多的用处呢,我很喜欢它。”
