摘要
笔者对26个油松种源在山西省隰县上庄种子园试验点的生长性状进行了观测研究。结果表明:种源间生长性状指标均差异显著,选择出2个材积生长遗传稳定性高的优良种源,分别为"蔡家川种源"和"三道川种源",其材积生长比对照分别高出88.71%和93.55%.同时选择出了5个优良林分,分别为"三道川侯家沟林分"、"三道川麻峪口林分"、"三道川陈家庄林分"、"三道川神堂沟林分"、"三道川木口沟林分"。并对山西关帝三道川"种源"和"林分"两个水平选择做了深入研究。
The quality and growth traits of the 26 Pinus tabulaeformis provenances in the seed orchard test points in Xi county of Shanxi were observed and studied. The results showed that the growth traits and quality indexes were significantly different between different provenances. 2 provenances of high genetic stability of growth in volume were chosen ( Huan- glong Caijiachuan in Shaanxi and Guandi Sandaochuan Pine in Shanxi) and the growth in volume ratios were respectively higher 88.71% and 93.55% than comparison. 5 superior plantations were chosen including Sandaochuan Houjiagou, Sandaochuan Mayukou, Sandaochuan Chenjiazhuang, Sandaochuan Shentanggou and Sandaochuan Mukougou. Two levels choice of provenances and forest of Guandi Sandaochuan Pine provenance in Shanxi was studied indepth.
