公路绿化是我区“三北”防扩林体系工程建设的一个组成部分,是有益当前,造福后代的百年大计。保护林木,发展林业,是一项紧迫的战略任务。河套灌区从七五年以来,各旗县公路段、工区在公路两侧采取开沟引水造林法,取得了显著成绩。但对盐碱度较大的非宜林地段没有采取有效的技术措施,造林成活率不高,因此,改造盐碱地,提高造林成活率,是加快河套地区公路绿化的迫切任务。
Highway greening is an integral part of the “Three North” anti-forest protection system construction in our district, which is beneficial to the present and a hundred years for the benefit of future generations. Protecting trees and developing forestry is an urgent strategic task. Hetao Irrigation District Since 1975, the highway sections and work areas of Qiqi County have adopted the ditching and diversion afforestation method on both sides of the road, and remarkable achievements have been made. However, no effective technical measures are taken for non-forest areas with large salinity and the afforestation survival rate is not high. Therefore, rebuilding the saline-alkali land and improving the survival rate of afforestation are urgent tasks to speed up highway greening in Hetao.
