开发利用适宜的野生植物资源应用于高速公路绿化，具有投资小、见效快和护坡性能强的特点。结合高速公路绿化的特点，对当地的野生狗牙根进行了植物学性状和生物学特性的定位观察记载，在村栽培技术进行了研究探讨后，大面积应用于高速公路边坡绿化获成功。实践证明，野生狗牙根在我国南北类似地区的高等级公路绿化中，是一个宝贵的种质资源。 Development and utilization of suitable wild plant resources used in highway greening, with a small investment, quick and slope protection performance characteristics. Combined with the characteristics of expressway greening, the local wild bermudagrass were recorded and observed for their botanical characters and biological characteristics. After the study of cultivation techniques in the village, large-area application of greening to the slope was successful. Practice has proved that wild bermudagrass is a valuable germplasm resource in the high-grade highway greening in similar areas of our country.
