公路是国家的重要基础设施。延长公路的使用年限,保证公路的畅通无阻是公路养护的重要职责和神圣使命,但由于公路裸露在大自然中,经常受到冰雹、暴雨、风沙等自然灾害的侵袭。为了减轻自然灾害给公路造成的损失,辽宁省从七十年代就开始这方面研究。通过多年观测,对比论证,发现灌木沙棘在这方面有独到的特殊功能,它既能减少风沙对公路的危害,又能防御水毁,是一种不可多得的公路绿化品种,同时沙棘果还有非常可观的经济价值。
The road is an important national infrastructure. Extending the service life of the highway and ensuring the smooth flow of the highway are the important duties and sacred mission of highway maintenance. However, due to the exposed road in the nature, the highway is often hit by natural disasters such as hail, rainstorms and sandstorms. In order to alleviate the damage caused by natural disasters to the highway, Liaoning Province started research in this field from the seventies. Through years of observation and comparison, it has been found that shrub seabuckthorn has unique special functions in this aspect. It not only can reduce the harm of wind-blown sand to the highway but also protect it from water damage, which is a rare species of highway greening, Have a very substantial economic value.
