摘要
[目的]选择生产力高、适应性强的樟子松种源，提高林地生产力。[方法]从1991年开始选取7个樟子松不同种源进行种源对比试验，造林后分别于1992、2010、2011年对樟子松不同种源子代林生长因子进行调查。[结果]长春净月潭樟子松种源及付家林场母树林种源非常适合付家地区生长，内蒙古红花尔基樟子松种源不适合在该地区生长。[结论]在今后的造林育种过程中应选择长春净月潭樟子松种源和当地母树林种源。
Abstract
Objective] The aim was to select the best provenance of Pinus sylvestris with high productivity and strong adaptation, to improve pro-ductivity of forest land.[Method] In 1991, seven provenances of P.sylvestris were selected to conduct provenance trial.After afforestation, the growth situation of progeny forest in 1992, 2010, 2011 was investigated.[Result] The offsprings belonging to the provenance of seed orchard in Jingyuetan, Changchun and seed trees in Fujia forest farm were most suitable for growth in Fujia region.The provenance of P.sylvestris in Hong-huaerji, Inner Mongolia was not fit for growth in Fujia forest farm.[Conclusion] Seed sources from Jingyuetan of Changchun and its local seed production stand should be selected in the future afforestation and breeding process.
