摘要
通过对洛南县春、秋两季不同自然条件的调查分析及在不同生态环境条件下,油松、侧柏飞播造林成苗数量。调查研究结果表明:秋季飞播造林出苗率和幼苗保存率明显高于春季飞播造林,因此,秋季是低山区飞播造林的最佳季节。
Aerial seeding carried out in Spring and Fall were investigated,indicating that germination rate and seedlings preserved during the fall were much better than those in Spring.The season of fall is believed to be the best for aerial seeding.
