近年来,由于木材消费量的迅速增长,木材供需矛盾日趋尖锐。世界各国都在采用大力营造速生丰产人工林的措施来迅速扩大森林资源。据多年来的造林实践经验,为提高人工造林的实际效果,确保林木生长量高,抗病虫害能力强,材质好,必须提高造林技术水平。目前,许多国家都很重视营造速生人工林技术研究工作,并设有专门的研究机构,研究和改革造林的各个技术环节并尽量地采用先进技术,使人工林达到优质高产。
In recent years, due to the rapid growth of timber consumption, the contradiction between supply and demand of timber has become increasingly acute. All countries in the world are adopting measures to vigorously create fast-growing and high-yield plantations to rapidly expand their forest resources. According to years of afforestation practice, in order to improve the actual effect of afforestation, to ensure that the high growth of trees, pest resistance and strong, good material, we must raise the level of afforestation technology. At present, many countries attach great importance to creating fast-growing plantation technology research and have specialized research institutes to study and reform all technical aspects of afforestation and try their best to use advanced technologies to achieve high-quality and high-yield plantations.
