摘要
[目的]探讨樟子松不同种源造林对子代生长各因子的影响,选择出适合在付家林场地区生长的樟子松种源。[方法]选取15个种源的樟子松进行造林对比试验,观测不同时期15个种源的树高、地径、胸径、蓄积量等指标。[结果]樟子松不同种源造林后对子代生长因子的影响较大,在付家地区13号付家林场种子园混合种子、1号付家林场母树林第1块标准地Ⅰ级木的种子、7号付家林场樟子松母树林第3块标准地Ⅱ级木的种子非常适合在付家林场地区生长,3号付家林场樟子松母树林第1块标准地Ⅲ级木的种子和15号内蒙古红花尔基种子不适合在付家林场地区生长。[结论]在今后的造林工作中尽量选用当地种子园生产的种子,其次选用樟子松母树林Ⅰ级或Ⅱ级木生产的种子,不能选用母树林Ⅲ级木生产的种子,内蒙古红花尔基地区的种子不适合在付家林场地区造林。
[Objective] To discuss the effects of afforestation of different provenances of Pinus sylvestris on growth factors of offspring,and to select the most suitable provenance for Fujia Forest Farm. [Method] A total of 15 provenances of P. sylvestris were selected for comparative research. After afforestation,indexes of 15 provenances were investigated,such as plant height,ground diameter,diameter at breast height,accumulation and so on.[Result] Hybrid seed provenance of 13 Fujia Forest Farm,Ⅰlevel provenance of standard sample plot 1 in Fujia Forest Farm number 1,and Ⅱ level provenance of standard sample plot 3 of P. sylvestris seed production stand in Fujia Forest Farm number 3 of P. sylvestris seed production stand in Fujia Forest Farm number 7 were extremely suitable for the growth condition in Fujia Forest Farm. However,Ⅲ level provenance of standard sample plot 1 of P. sylvestris seed production stand in Fujia Forest Farm number 3 and provenance of Inner Mongolia Honghuaerji forest were not suitable to grow in Fujia Forest Farm.[Conclusion]The seed of local seed orchard is the first choice; provenances of levelⅠorⅡin P. sylvestris seed production stand are the second choice for afforestation in the future. Level Ⅲ in P. sylvestris seed production stand should never be chosen. Observation through many years showed that Inner Mongolia Honghuaerji forest is not fit for afforestation in Fujia Forest Farm.
