以河北、山西、北京、甘肃和内蒙古收集的24份华北落叶松种源为试材,在河北围场、河北赤城和山西静乐3个试验点进行了区域化试验,并应用AMMI模型对试验林的生长进行了分析,以期选育生长量大且适生性好的华北落叶松优良种源。结果表明:华北落叶松种源株高和地径均与环境存在互作效应,山西浑源(13号)、围场1~9(19号)和围场8~74(24号)为高产稳产种源,北京种源(6号)和围场7~46(23号)为高产种源,但稳产性略差。综合生长的适应性和稳定性考虑,这5个种源均适合在3个试验区应用推广。
Twenty-four provenances of Larix principis-rupprechtii collected in Hebei, Shanxi, Beijing, Gansu and Inner Mongolia were used as test materials. Regional experiments were conducted at three test sites in Hebei paddock, Hebei Chicheng and Shanxi Jingle. AMMI models The growth of the Larix principis-rupprechtii was studied in order to breed the good provenance of Larix principis-rupprechtii with large growth and good adaptability. The results showed that both the plant height and the diameter of Larix principis-rupprechtii could interact with the environment. Shanxi Hunyuan (No. 13), Yantai 1 ~ 9 (No.19) and Yard 8 ~ 74 (No.24) Source, Beijing Provenance (No.6) and Yard7 ~ 46 (No.23) are high-yielding provenances, but their stable yield is slightly worse. Considering the adaptability and stability of comprehensive growth, all five provenances were suitable for popularization in three experimental areas.
