黑云杉、白云杉苗期生长性状研究

本试验对引进加拿大的黑云杉3个种源和白云杉4个种源及当地的红皮云杉进行了苗期生长性状的研究,通过对1年生苗期的高生长和径生长的数据整理分析,结果表明,3种云杉以苗期高生长差异显著,但径生长不显著。3种云杉以苗期高生长排序为白云杉>黑云杉>红皮云杉。同时对黑云杉、白云杉的种源进行了研究,结果表明,白云杉的7号种源和黑云杉的3号种源分别在高生长和径生长上有较好的适应性,可作为本引种试验的优良种源。

Studying On The Growth Characteristics of The Black Spruce and the White Spruce During the seedling stage

Through this experiment we studied the growth characteristics of 3 Canadian provenances of Black Spruce and 4 Canadian provenances of White Spruce and the local species of Picea Koraiensis during the seedling stage.analyzing of data of height and radial growth of annual seedling in during the seedling stage,the results showed that height growth of 3 Chinese Spruce species in during the seedling stage.The radial growth wasn't significantly different.The order of the height growth of 3 Chinese Spruce species during the seedling stage is:White Spruce >Black Spruce >Picea Koraiensis.At the same time we have also done the provenance trials of Black Spruce and the White Spruce.The results indicate that the provenance of the 7th White Spruce and the 3rd Black Spruce has better adaptability of height and radial growth in this area.So they can be the superior provenances of this introducing experiment.
