摘要
针对洪泽湖大堤防浪柳林成活率低的问题,开展了洪泽湖大堤柳树造林试验。通过对造林后柳树叶绿素含量的测定及成活率、保存率及生长情况的调查,结果表明:使用172杂交柳带根苗与1年生扦插苗造林效果比较好,成活率都在97%以上,以选择1年生扦插栽植方式为最佳。由此归纳出提高洪泽湖防浪柳林成活率的综合技术措施。
Aiming at the problems of lower survival ratio of willow on the embankment of Hongze Lake on where experiments of forestation of willow were conducted, By investigation on survival and preserving ratio and growth and determination of content of chlorophyll of willow after forestation, the results show that the effect are better by using remain-roots-seedlings of hybrid willow and 1-year-old cutting seedlings. The survival ratios are above 97%. Choosing the latter has the optimal effect.
