大叶冬青不同混交造林模式的生长效果比较

摘要

Mixed afforestation experiment of Ilex latifolia Thunb was conducted by randomized complete block design.The results showed that I.latifolia Thunb and Pinus massoniana Lamb were adaptable for the climate and soil of the site,and P.massoniana Lamb was an ideal species to mix with I.latifolia Thunb.The mixed planting of I.latifolia Thunb × P.massoniana Lamb was able to promote the growth of them and should be popularized in the plantation under the same conditions.When Fokienia hodginsii（Dunn） Henry et Tho or Manglietia yuyuanensis Law was mixed with I.latofolia Thunb.the growth of trees was also promoted,so the mixed forest of I.latifolia Thunb and F.hodginsii（Dunn） Henry et Tho or M.yuyuanensis Law could be created according to particular conditions.Betula luminifera was not adaptable for the conditions of the experimental site,so the mixed plantation of I.latifolia Thunb and B.luminifera proved to be a failure in growing well.%采用完全随机区组进行大叶冬青混交试验。结果表明,大叶冬青、马尾松比较适合试验地气候、土壤,马尾松是大叶冬青的较佳混交树种,大叶冬青×马尾松混交能够促进大叶冬青和马尾松的生长,可在同立地条件林地进行推广;建柏、乳源木莲与大叶冬青混交也能不同程度地促进林木的生长,可根据具体情况营造大叶冬青和建柏或乳源木莲的混交林;光皮桦不能适应该立地条件,大叶冬青和光皮桦混交林的生长状况不良。
