通过调查，认为日本落叶松在我县表现出良好的适生性，与长白落叶松相比，生长快、抗病虫害能力强是其最大特点。建议应重点研究并发展这一优良速生树种。 Through the investigation, we believe that Japanese larch showed good adaptability in our county. Compared with Changbai larch, it grows fast and its pest resistance is strong. Suggestions should focus on research and development of this excellent fast-growing tree species.
