[11/18][风景]胡杨——沙漠的脊梁[18P]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 胡杨是亚非荒漠地区典型的替水旱中生至中生植物,长期适应极端干旱的大陆性气候;对温度大幅度变化的适应能力很强,喜光,喜土壤湿润,耐大气干旱,耐高温,也较耐寒;适生于10℃以上积温2000~4 500℃之间的暖温带荒漠气候,在积温4000℃以上的暖温带荒漠河流沿岸、河漫滩细沙——沙质土上生长最为良好。能够忍耐极端最高温45℃和极端最低温-40℃的袭击。胡杨耐盐碱能力较强,在1米以内土壤总盐量在1%以下时,生长良好;总盐量在2~3%时,生长受到抑制;当总盐量超过3%时,便成片死亡。花期5月,果期6~7月。<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 胡杨,是我平生所见最坚韧的树。能在零上40度的烈日中娇艳,能在零下40度的严寒中挺拔。不怕侵入骨髓的斑斑盐碱,不怕铺天盖脑的层层风沙,它是神树,是生命的树,是不死的树。那种遇强则强、逆境奋起、一息尚存、绝不放弃的精神,使所有真正的男儿血脉贲张。霜风击倒,挣扎爬起,沙尘掩盖,奋力撑出。它们为精神而从容赴义,它们为理念而慷慨就死。虽断臂折腰,仍死挺着那一副铁铮铮的风骨;虽痕伤累累,仍显现着那一腔硬朗朗的本色。<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;胡杨,是我平生所见最无私的树。胡杨是挡在沙漠前的屏障,身后是城市,是村庄,是青山绿水,是喧闹的红尘世界,是并不了解它们的芸芸众生。身后的芸芸众生,是它们生下来、活下去、斗到底的唯一意义。它们不在乎,它们并不期望人们知道它们,它们将一切浮华虚名让给了牡丹,让给了桃花,让给了所有稍纵即逝的奇花异草,而将这摧肝裂胆的风沙留给了自己。<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 胡杨,是我平生所见最悲壮的树。胡杨生下来一千年不死,死了后一千年不倒,倒下去一千年不朽。这不是神话。无论是在塔里木,还是在内蒙额济纳旗,我都看见了大片壮阔无边的枯杨。它们生前为所挚爱的热土战斗到最后一刻,死后仍奇形怪状地挺立在战友与敌人之间。它们让战友落泪,它们让敌人尊敬。那亿万棵宁死不屈、双拳紧握的枯杨,似一幅悲天悯人的冬天童话。 <BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395887656250.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395887656250.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395892343750.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395892343750.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395895625000.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395895625000.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395898750000.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395898750000.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395901406250.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395901406250.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395904687500.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395904687500.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395907343750.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395907343750.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395910312500.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395910312500.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395828750000.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395828750000.jpg" border=0><BR><BR><IMG onclick="if(this.width>screen.width-461) window.open('http://w1.epaike.com/2008/11/16/mid_633624395832343750.jpg');" src="http://w1.epaike.com/2008/11/16/mid_633624395832343750.jpg" border=0><BR>
