摘要
本研究从1990年开始对洪泽湖大堤迎湖面林台上新植的插干旱柳(SalixmalsudanaKoidz)的生长进行了观察,对洪泽湖大堤的小气候因子、土壤因子进行了测定,分析了这些自然条件与柳树生长的关系以及病虫害、栽培技术对柳树生长的影响,从而明确了影响柳树成活的原因。针对柳树死因,设计了4种栽植方式并进行比较试验,优选出可以大幅度提高柳树更新成活率的最佳栽植方式,提出了提高柳树成活率的一套栽培技术措施。
Branch cuts of Salix
matsudana were used in the regeneration of willow wood in the terrace along dam of Hongze
Lake,but the survival rate was very low. The effects of micro-climatic factors,soil water content.
soil air conductivi- ty,harmful insects,disease and poor culture techniques on the growth of
willow have been studied since 1990.The fac-tors causing the death of newly cultured willows
were revealed. Four culture models in accordance with the death causes were designed in an
attempt to increase survival rate of willow. At the end of 2nd year's experiment,the results
showed that one of the four culture models can increase the suvrival rate of willow
significantly. Based on the experiment,a new culture system was suggested in the paper..
