[ 发布日期:2018-10-10] 点击:11525

公路边坡绿化植物防护的主要目的是固土护坡、防止冲刷,兼有美化环境的功能。一般应选择干旱、瘠薄、根系发达、覆盖度好、易于成活、便于管理、同时兼顾景观效果的草本或木本植物。边坡以种植草本地被为主,根据不同地段的实际情况,采用丛植、列植等绿化模式,尽量做到乔、灌、花、草搭配,形成不同景观的植物群落贵州边坡绿化。

客土喷播

公路边坡绿化的植物定居后,在其群落结构中,仍是以草本植物为主,灌木属于从属的位置,因为草本植物早期生长速度非常快,而且耐贫瘠,这样可以尽快恢复边坡的植被覆盖,控制土壤流失,美化路容。但是这样的植物群落结构非常的不稳定,如果措施跟不上,草本植物过度发育,群落中的灌木很快就会因为营养、阳光、水分和其他资源不足而被草本植物"吃掉",另一方面一旦草本植物把土壤中的营养捎耗到一定程度,很可能出现大面积的衰退,并且重新回到裸地的状态。这种现象已经在以往的高速公路植被恢复建设中已经是屡见不鲜。未雨绸缪,制定合理养护管理措施,促进植物群落向目标群落转化,是公路边坡绿化的重要内容,主要养护措施包括肥水管理措施、补栽措施、其他辅助管理措施等贵州边坡绿化。
