摘要
总结了公路建设植被恢复的农艺技术措施,并取得较好的效果。当年植被盖度达80%以上,高度达2～20cm;移植草皮盖度达50%～80%,基本达到原生植被的盖度;采用方格网或复土20cm栽培牧草比复土5cm和直播区出苗数量高1 98倍;使用无纺布覆盖和吸水剂拌种在试验区可提高出苗率1～2倍和10%～20%。
The Agro-techniques for restoring the vegetation after road construction have been briefly summarized. The application of these techniques has achieved good effects in general, and the vegetation coverage reached to 80% or above and the average plant height reached to 2-20 cm in the same year after the methods sere taken. The vegetation coverage reached to 50%-80% in the areas where sod was trans-planted, which is about the same coverage of the original vegetation. The number of germinated seedling in the area covered with 5cm depth of soil or cement-grided area is 1.98 to,es pf that of the control area. The germination rate in the plots covered by adhesive-bonded fabric of treated by moisture adsorbent by 1-2 times and 10%-40% respectively.
