风景预览

以山青、水秀、洞奇、石美为特色的桂林风景,随着季节、早晚、晴雨的不同,又能变幻出各种意境不同的景观,令人流连忘返。无怪乎历代以“江作青罗带,山如碧玉簪”、“桂林山水甲天下”等诗句来描绘赞美这里的山光水色。


停车座爱枫林晚霜叶红于二月花

  • 枫叶 落叶树种在秋冬的时后,体内会产生一些化学变化,让原本树叶中所含的有用的物质或部份组织分解之后,回收储藏在茎或根的部位,来年春天的时候可以再利用,叶绿体、叶绿素就是被分解回收的对象之一,因此当叶子里的叶绿素没有了的时候,其它色素的颜色彰显出来,如花青素的红色、胡萝卜素的黄色等! 接下来就要调叶子过冬了!



松树的品种在全世界有100多种,全是阳性速生树种,除幼苗期间需要些庇荫外,在生长期都喜欢光照和肥沃湿润的土壤
