摘要
洪泽湖大堤插干植柳的方法更新迎水面原有柳树防浪林,成活率极低。通过对柳树的生长进行观察,对洪泽湖大堤的土壤、气候条件进行测定,分析了各因子与柳树生长的关系,从而明确影响柳树成活的原因:土壤含水量高、土壤黏重板结、插干病虫害严重、插干埋土过深、缺乏管理等因素相互作用、综合影响。
The survival rate of willow inarched in the embankment of Hongze lake to replace the original wave break forest is very low. The author analyzed the soil and climate around the Hongze lake, observed the growth of willows. Ultimately, the influencing factors of willows＇ survival percent were found out. Soil moisture content was high; the soils were sticky and harden. The plant diseases and insect pests were very serious. The transplanting cuttings were buried over deeply. Lacking of management and other factors interacted themselves.
