冬季伐树的季节到了,农村传统地挖掘采伐方法既费工费力又不科学,尤其是生长快、材质优、价值高的泡桐树蒙受的经济损失更大。挖掘采伐比从贴地面锯伐看起来多挖出半米圆锥形的树桩,而破坏损失了贮存着大量营养宠大根系的再利用。在挖掘坑内虽然也会从局部的断根上发出许多丛生的萌生苗,因不是完整根系贮存的营养不多,苗长得质弱又杂乱无章,没有实用价值;有的随伐树随填坑,发出萌生苗也不要,将它及早掰掉。由此,造成资源上的巨大浪费。泡桐是侧根发达的深根性树种,有数条强大的侧根呈爪形向下伸展,根系一般分上
The season of winter tree cutting is coming. The rural traditional methods of cutting and harvesting are labor-intensive and unscientific. In particular, the high-growth, high-quality and high-value Paulownia trees suffer greater economic losses. Digging Harvesting It seems that more than half a meter of conical stumps have been excavated from the ground sawing, while the destruction has lost the reuse of large root systems that stock large quantities of nutrients. In the digging pit, although many clusters of sprouting seedlings emerge from the local roots, there are not enough nutrients to store the whole root system. The seedlings are weak and messy and have no practical value. Some of them are distributed with the pit, Sprout does not want, it will be broken off early. As a result, a huge waste of resources. Paulownia is a deep-rooted lateral rootstock tree species, there are several powerful lateral roots claw downward stretch, the root of the general points
