我省历年飞播造林后,常常由于种子发芽出苗阶段水分不足和鸟兽危害,严重影响飞播造林成果。在比较干旱缺雨的予北太行山区和予西崤山黄土复盖石质山地,这种情况更为突出,为提高飞播造林成效,扩大飞播范围,加速我省荒山绿化,今年,我们在予北太行山的汲县飞播试验大粒化(泥丸) After years of aerial sowing afforestation in our province, often due to lack of water in the seedling emergence stage and the dangers of birds and beasts, the results of aerial seeding and afforestation are seriously affected. This situation is even more prominent in the more impoverished and rain-prone areas to the North Taihang Mountains and to cover Xizang Mountain loess with stony mountains.
