【摘要】 对20世纪80年代引种到湖北宜昌大老岭林场的北美、西欧、日本原产优良工业用材针叶树种的生长适应性等进行了研究.结果表明,欧洲云杉、日本冷杉表现突出,后期生长较快,后8 a年平均高生长都超过50 cm;欧洲赤松不同种源差异显著,其中优良种源在本地区有一定发展可能,法国奥尔良种源可作为优良种源进行推广;花旗松生长适应性较差,不经严格的再选择,难以直接大量引种.更多还原

【Abstract】 After the introduction of Picea abies,Abies firma,Pinus sylvestris,Pseudotsuga menziesii to Yichang Dalaoling forest farm of Hubei province in the 1980,an investigation lasting over 20 years on their acclimation was conducted.Results indicate that Picea abies and Abies firma are adaptable to the forest fields in Yichang and have a better performance than native species,Pinus tabulaeformis Carr.The growth is faster in anaphase than in prophase and average annual height is above 50 cm.There exists significant difference in tree height and breast diameter among varied provenance of Pinus sylvestris,among which the best provenances can be introduced to afforestation in Yichang.The French Orleans Provenace is the best provenance and can be afforestated in Yichang in the future.The growth and phenological adaptation of Pseudotsuga menziesii are inferior to the above three species.It is undesirable to introduce this species in large quantity unless after strict reselection.更多还原
