我县从一九七四年开始搞雨季油松飞机播种造林,已经六年。实践证明,象我们这样的北方干寒山区,同样适宜搞飞播造林。八达营公社飞播造林试验后,狠抓封山育林和人工造林,创造了一条“飞封造”的路子。七年时间,荒山与四旁绿化双上《纲要》。从实践看“飞封造”三结合的办法效果很好,是加速绿化山区,恢复生态平衡,逐渐改变农业内部的比例关系,是由穷变富的重要途径。 It has been six years since our county began planting seeding of pine seeds in the rainy season in 1974. Practice has proved that, like us, dry and cold mountainous areas in the north, are also suitable for aerial sowing and afforestation. Octopus commune aerial seeding afforestation test, pay close attention to closing hillsides afforestation and afforestation, to create a “fly closure made” approach. Seven years, barren hills and green on both sides of the “Outline.” From practice, “flying closure” triple combination of the effect is very good, is to speed up the green mountain, restore ecological balance, and gradually change the proportion of agriculture within the relationship between the poor is an important way to become rich.
