在过去的40年,东北林区的紫椴资源受到了超限开发和无序利用,这导致目前紫椴在东北出现了天然分布面积萎缩、总体数量降低和资源品质下降的危机,这是林业工作巨大的损失和遗憾。本文首先说明了紫椴的生物形态和功能,简介了紫椴的繁殖技术和方式,在此基础上,阐述了紫椴栽培工作应该注意的要点,并对东北林区紫椴栽培技术的发展进行了畅想,为区域内林业科技人员掌握和熟练紫椴栽培技术起到了经验总结和发展预测的作用。
Over the past 40 years, the Tilia amurensis resources in the northeastern forest have been over-exploited and disordered, resulting in the current crisis in the northeast of Tilia with a decline in the natural distribution area, a decrease in the overall population and a decline in the quality of resources, Work huge loss and regret. This paper first describes the biological morphology and function of Tilia amurensis, describes the propagation techniques and ways of Tilia amurensis, and on this basis, elaborates the points that should be paid attention to in the cultivation of Tilia amurensis and the development of the cultivation techniques of Tilia amurensis in Northeast China Imagination for the forestry science and technology personnel in the region to master and skilled cultivation techniques played a linden experience summed up and forecast the development of the role.
