通过对曲江、小坑、龙山林场杉木同一家系的扦插苗与实生苗造林观测,发现杉木无性群体与实生群体之间生长量基本上并无显著差异。但在不同的造林地点,不同家系间表现有所不同,曲江、龙山林场扦插林高生长优于实生林,小坑林场实生林则生长优于扦插林。采用成对平均数方法进行差异显著性检验结果,达较显著水平以上的家系占53.8%。参试13个家系扦插林高生长优于实生林占84.6%,实生林优于扦插林占15.4%,扦插林为实生林高生长的105%(其中GD11066家系,扦插林生长突出,其高生长三地平均值为实生林高生长的118%)。胸径生长则扦插林为实生林的106%。扦插林树高变异系数为19.8%,而实生林则为22.3%,无性群体比有性群体变异程度较小。而胸径变异系数,则两者基本相同。
Through the afforestation of cuttings and seedlings of the same family with the same family of Chinese fir in Qujiang, XiaoKeng and Longshan, the results showed that there was basically no significant difference in growth between the Chinese fir and the live population. However, in different afforestation sites, the performance of different families was different. The cutting height of the forest in Qujiang and Longshan stands was superior to that of the real forest, and the growth of the real forest in Xiaokeng forest farm was better than that of the cutting forest. The means of pairwise average method was used to test the significance of the difference, reaching 53.8% of the pedigrees above the significant level. The results showed that the growth of cutting height of 13 families was better than that of real wood, accounting for 84.6% of the total, the real wood was 15.4% better than cutting forest, and the cuttings forest was 105% of the real woodland height growth (GD11066, , The average growth of the three places is 118% of the growth of real forest height). The DBH growth is 106% of the real forest. The coefficient of variation of cutting tree was 19.8%, while that of real plantation was 22.3%. The degree of variability of vegetative group was smaller than that of sexual group. The coefficient of variation of DBH, the two are basically the same.
