落叶松是我国高山地区重要造林树种,具适生性强和早期生长快的特点。我场地处鄂西高寒山区,现有阔叶林生产力和出材率低,六十年代营造的华山松虽已成林,但早期生长慢,落叶病严重,现林分年生长量已大大下降,油松林也因年积温不够,生长缓慢。为了引进适宜树种以提高我场林分生产力,1980年参加了中国林业科学研究院林研所主持的全国落叶松种和种源选择试验协作组,按统一试验方案在
Larch is an important afforestation tree species in high mountain areas of our country, with strong adaptability and early growth characteristics. My field is located in the alpine mountainous area of Western Hubei Province. The existing productivity and yield of existing broad-leaved forests are low. Although the P. arborvitae that was built in the 1960s has become a forest, its early growth is slow and its defoliation is severe. , Pine forest also due to lack of accumulated temperature, slow growth. In order to introduce appropriate tree species in order to improve the productivity of my field, I participated in the National Larch Seed and Source Selection Experiment Collaboration Team hosted by Lin Institute of Chinese Academy of Forestry in 1980. According to the unified experimental plan,
