水湿地江南桤木经营技术研究

Study on management technology of Jiangnan alnus in water wetland

摘要: 研究不同经营技术处理对地下水位、林木生长量及根系生长量的影响，结果表明：高垅低沟处理（GD）、切根浅栽处理（QQ）和开沟切根集成处置处理（JC）都能起到降低地下水位，促进林木生长发育的作用。以开沟切根集成处置处理效果最好，是适宜山地宜林水湿地营造江南桤木林的经营技术。

Abstract: Effects of different management technology on underground water level,volume of forest tree growth and root growth amount were studied.The results showed that all the treatments of high ridge and low ditch,shallow planting of cutting root,and integrated disposal of ditching and cutting root could reduce the underground water level and promote the growth and development of trees.Among which,the effect of integrated disposal of ditching and cutting root was the best and was the suitable management technology for constructing Jiangnan alnus forest in water wetland where suitable to grow forestry in mountainous area.
