根据调查研究和３０多年的生产实践，我们认为在北亚热带南缘的太子山地区，在适合杉木生长的宜林地段，杉木采伐后仍然栽杉木。原不适宜杉木生长的土壤，第一代杉木长得不好的地段，杉木采伐后应改换其它树种。更新方式分为两种，一是大面积植苗造林，二是少数地区可以控制采用萌芽更新。 According to the investigation and research and more than 30 years of production practice, we think that in the area of ​​Prince Edward Mountain in the southern margin of the northern subtropics, fir is still planted after harvesting in suitable areas suitable for fir growth. The original soil is not suitable for the growth of fir, the first generation of badly-growing Chinese fir, fir should be replaced after the logging of other species. There are two ways to update, the first is to plant large areas of seedlings and the other is to control the use of sprouting and regeneration in a few areas.
