泡桐幼苗在北方地区,一般顶芽及顶部第一、二对腋芽每年落叶后多因组织不充实不能越冬而枯死,翌春从第三、四对腋芽萌发出侧生枝而形成假二叉枝,造成主干低矮,出材率低,从而降低了经济价值。为培养高干无节的优质材,我们应用了斜截接干新技术。这一新技术的具体做法是:在造林后第一年春季或是平茬后第二年春季树腋开始流动,至新芽长到3—4厘米时,选择树苗顶端尖削度变化明显处约3—4节上,以迎风方向饱满健壮的芽作为接干芽,然后以不损伤节间隔膜为原则,以接干芽的上方0.5厘米处至对生芽的叶痕下沿斜
Paulownia seedlings in the northern region, the general top buds and the top of the first, two pairs of axillary buds each year after deciduous due to insufficient tissue can not wintering and died, the next spring from the third and fourth pairs of axillary buds sprouting lateral branches and the formation of bifurcation, Resulting in low backbone, a low yield, thus reducing the economic value. In order to cultivate high-quality and high-quality materials, we have applied the new technology of oblique cut-and-dry. The specific approach of this new technology is: in the first year after afforestation spring or stubble second spring spring tree arches began to flow until the sprouts grow to 3-4 cm, choose sapling tip taper changes significantly Section 3-4, the full and strong buds in the windward direction as the dry bud, and then to not damage the septal diaphragm principle, to take the top of the dry bud 0.5 cm to the lower edge of the bud along the bud
