杉木采伐迹地两种更新方式调查初报

Primary report on investigation oftwo regeneration ways of chinesefir''''s slashings

摘要:

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。

Abstract:

According to our investigation & research and more than 30 years' practical experience on chinese fir's slashing, we thought that: In the Taizishan district (which locates in the south margin of the north subtropics),when some sections of chinese fir'sslashing are suitable for the tree growth, it is a section suitable for the forest, in thesame place,the original species-chinese fir must be planted or regenerated after the tree being harvested;when some sections are unsuitable for the tree growth,and the frist generation of chinese fir doesn't grows well in it,so,it is a soil unsuitablefor the forest, in this place, chinese fir seedling must be replaed by other new speciesseedling. There are two regeneration ways to be selected,one is forest planting in thelarge areas,the other is cotrolled regeneration by germination in minor areas.
