摘　　要：通过在江汉平原开展中山杉6个品系的引种造林试验。结果表明,引进的6个品系中山杉无严重病虫害发生,各生长指标均大于池杉,11 a生中山杉平均胸径为17.61 cm、树高为11.06 m、材积为0.1297 m^3,表明中山杉在江汉平原的引种试验基本成功,其中中山杉502和中山杉118最为突出,适合在江汉平原推广造林,丰富江汉平原造林树种。Through the introduction and silviculture experiment of 6 strains of Taxodium hybrid‘Zhongshanshan’in Jianghan Plain.The results showed that:the six introducted strains of Taxodium hybrid have no serious plant diseases and insect pests,all growth indexes are greater than Taxodium ascendens,the measures to11-year-old Taxodium hybrid‘Zhongshanshan’,with 17.61 cm diameter at breast height,11.06 m height,and 0.1297 m^3 volume,the introduction test of Taxodium hybrid‘Zhongshanshan’in Jianghan Plain is successful a.The most prominent are Taxodium hybrid‘Zhongshanshan502’and Taxodium hybrid‘Zhongshanshan118’,which are suitable for promoting afforestation in Jianghan Plain,and then enrich tree species diversity in Jianghan Plain.
