我省栎类造林一直沿用直播的方法。但近十余年来由于鼠害猖獗,造林多归失败。改用育苗造林,又因苗木主根深,侧根少,栽植成活率很低,致使栎类造林处于停顿状态。因此,提高栎类造林成活率,已成为我省林业生产中急待解决的技术问题。我们经过多次调查,反复试验,摸索出栎类抑制主根育苗的新方法,有效地控制了主根深度,促使 Quercus afforestation in our province has been used direct broadcast method. However, due to rampant rodents over the past decade or so, afforestation and more failed. Switch to nursery afforestation, and because of the main root seedling deep, less lateral, planting survival rate is very low, resulting in oak afforestation at a standstill. Therefore, increasing the survival rate of oak afforestation has become an urgent technical solution to the forestry production in our province. After many investigations and repeated experiments, we found out a new method of quercus cutting inhibition of root nursery seedlings, effectively controlling the depth of the main root,
