杉木(Cunninqhamia Lanceolata HK.)是南方各省(区)最主要的造林树种。杉木优质苗木是速生丰产林基地建设和工程造林的重要物质基础。人们虽已对杉木地理类型及种源等方面进行过大最研究,但探索培育杉木优质苗木的综合技术,以求得遗传品质、环境条件与表型的统一,进而掌握杉苗的最佳生长环境及其培育技术措施仍然是营林技术工作中的一项重要课题。因此,我们自1986年至1987年开始进行了杉木优质壮苗培育综合技术研究,现将结果初报如下。
Chinese fir (Cunninqhamia Lanceolata HK.) Is the most important afforestation species in the southern provinces (autonomous regions). Chinese fir seedling is an important material basis for the construction of fast-growing and high-yield forest base and afforestation. Though people have carried out the most research on the geographical types and provenances of Cunninghamia lanceolata, they have explored the integrated techniques of cultivating high quality seedlings of Cunninghamia lanceolata so as to obtain the unification of genetic quality, environmental conditions and phenotypes and further grasp the optimal growth of Cunninghamia lanceolata The environment and its cultivation technology measures remain an important issue in the technical work on silviculture. Therefore, we started from 1986 to 1987 the fir seedling cultivation comprehensive technology research, the results are as follows.
