摘要
对引进美国的湿地松(Pinus taeda)和火炬松(Pinus elliottii)的生长状况,与当地马尾松(Pinus smassoniana)进行对比分析。第15年试验测定结果表明:在同样的立地和抚育条件下,马尾松在生长量方面表现最好,而湿地松在通直度、分枝角度等树形指标方面表现最优。综合各因子,选出了火炬松、湿地松各1个优良家系和3个马尾松优良家系作为育种和推广材料。
The growth characteristics of Pinus taeda and Pinus elliottii introduced from America were compared with that of the native Pinus massoniana. The results in the fifteenth year indicated that under the same condition of site and cultivation, Pinus massoniana showed the best growth performance, while Pinus elliottii showed the best performance in stem form and branching angle. Comprehensive speaking, one superior family from Pinus taeda and Pinus elliottii and three families from Pinus massoniana were se- lected as breeding and extension materials.
