森林本身的自我施肥,是森林土壤肥力保持和提高的基础。吉林省林业经营水平不高,天然林面积广大,提高森林土壤肥力的途径,应以充分利用森林自我施肥能力为主。保护与利用好现有的森林资源,废除皆伐,采用适度择伐;大力造林,並适当地对部分林种进行施肥;科学地经营现存的过伐林和次生林。从而充分利用土地生产力,以保证森林发挥最大的效益功能,使之“青山常在,永续利用”。
The self-fertilization of the forest itself is the basis for the maintenance and improvement of forest soil fertility. Jilin forestry management is not high, the vast area of natural forests, forest soil fertility ways to make full use of forest self-fertility should be based. To protect and make good use of existing forest resources, to abolish clear cutting and to adopt appropriate selective cutting methods; to afforest forests vigorously and properly fertilize some forest species; and to operate scalded and secondary forests scientifically. In order to make full use of land productivity, in order to ensure that forests play the greatest effectiveness of the function, so that “green mountains often, sustainable use.”
