摘要
人参和西洋参的连作障碍一直是困扰长白山区参业持续发展和森林生态保护的重大科学技术与社会发展问题之一。多年来,针对这一重大问题,科研工作者开展了大量的研究工作,但到目前为止这一问题仍未得到根本解决。文中在分析目前参地开发和参后地生态恢复与再利用现状、人参和西洋参忌连作的可能因素、参地开发的林分条件、现有参后地地形条件及参后地生态恢复的长期性等基础上,提出了以地形条件为基础的参后地生态恢复与再利用模式,包括较陡坡地模式、缓坡地模式和岗平地模式;提出了目前参后地生态恢复与再利用急需解决的几个关键问题,包括制定合理的参后地生态恢复与再利用总体规划、参后地还林与再利用政策的调整、提高参后地生态恢复与再利用的科技含量,以及充分探讨和研究参后地6～10年轮作制的可行性等。
The continuous cultivation obstruction of ginseng and American ginseng was always a serious problem puzzling the sustainable development of ginseng industry and ecological protection of forest in the Changbai Mountainous Area. For years, large numbers of studies have been made in allusion, but as yet, it has not neen solved drastically. On the basis of analyzing the actuality of ginseng development and old ginseng ecological restoration, and the likely factors of continuous cultivation obstruction, forest environment before ginseng land cultivation, the landform of old ginseng land and the long-term nature of old ginseng ecological restoration, we put forward the modes of ecological restoration and reuse of old ginseng land on the basis of landform condition, including steep slope land mode, gentle slope land mode and level ground mode. We also take into consideration some problems to be solved in the ecological restoration and reuse of old ginseng land, such as to establish a whole plan on ecological restoration and reuse of old ginseng land, to regulate the policy on back-forest and reuse of old ginseng land, to advance the study on ecological restoration and reuse of old ginseng land, and to make research on the feasibility of the rotation of ginseng and crops or other economic plants for 6～10 years.
