参地再利用问题是长期解决不了的难题。不仅存在着参、林矛盾,更难于实现参业的大发展。虽然1956年开始研究参地再利用问题至今经过了二十多年的时间,由于难度大和对其根源缺乏足够的研究,因而始终没有解决。而对参地不能再利用的原因存在各种不同的看法。有的认为主要根源是缺乏营养;也有认为是种过参的地再种参缺水的缘故。所以在参地再利用研究上,必须先将不能利用的根源,尤其是主要根源研究清楚,方能指导参地再利用。现将近几年来,在参地不能再利用根源的研究和解决途径, The problem of land re-use is a long-term problem that can not be solved. Not only the participation and the contradiction between forests but also the greater development of participating in the industry are more difficult to achieve. Although it has been more than two decades since the study on the recycle of geo-reefs began in 1956, it has not been solved due to the difficulty and the lack of adequate research on its root causes. There are various opinions on the reasons why the land can not be reused. Some think the main root cause is the lack of nutrition; there are also those who think that it is too kind of a place to go and then a kind of lack of water. Therefore, in the study of recycle, we must first study the root causes that can not be used, especially the study of the main causes, so as to guide the re-use of the reference materials. Now in recent years, in the ground can no longer use the roots of research and solutions,
