适地适树就是根据既定的经营目的和造林地,选择适宜的造林树种,或根据既定的树种选择合适的造林地。它是造林能否成功的一项关键措施。建国以来的大量造林实践证明,如果能做到适地适树,再加上一些其它必要的措施,造林就能基本成功;如果做不到适地适树,即便其它措施都好,造林也难以成功,往往表现为成活而不能成林,或成林而不能成材。这不但造成巨大的经济损失,而且还耽误了完成绿化祖国任务的宝贵时间。为了要做到适地适树,首先要掌握“地”和“树”的客观规律,也就是要掌握造林地的立地条件和造林树种对环境条件的要求(生态学特性),然后使它们在符合造林目的要求的基础上辩证地统一起来。
Appropriate tree planting is based on established business purposes and afforestation, choose the appropriate afforestation species, or according to the established species to choose the right afforestation. It is a key measure of the success of afforestation. A large number of afforestation practices since the founding of the People’s Republic of China have proved that afforestation can be basically successful if it can be properly adapted to trees and some other necessary measures. Even if other measures are not properly adopted, reforestation is difficult Success, often manifested as survival can not become a forest, or become a forest and can not be made. This not only caused tremendous economic losses but also delayed the precious time for completing the task of greening the motherland. In order to be suitable for tree planting, we must first grasp the objective laws of “land” and “tree”, that is, we must understand the site conditions of afforestation land and the environmental requirements (afforestation characteristics) of afforestation species and then make them In line with the requirements of afforestation on the basis of dialectical unity.
