陕西飞播造林自1958年春首次在榆林沙区试播以来,经十多年试验和扩大试验,70年代在秦巴山区和黄土高原、榆林沙区相继成功。从1980年起,特别是1983年邓小平同志对陕西吴旗县飞播沙打旺成功一文批示后,我省飞播造林步伐加快,每年以100～140万亩的速度迅猛发展,成为陕西省荒山 Since its first sowing in Yulin sandy area in the spring of 1958, Shaanxi aerial seeding has undergone more than ten years of experiments and expanded tests. In the 1970s, it succeeded in the Qinba Mountains, Loess Plateau and Yulin Sand Area. Since 1980, especially since Comrade Deng Xiaoping made a success story about the successful broadcasting of sandcastle in Wuqi County, Shaanxi Province in 1983, the pace of afforestation and afforestation in our province has accelerated. The area is growing rapidly at a rate of 100-140 mu per year and has become a barren mountain in Shaanxi Province
