摘要
对4个耐水湿树种在太湖滩涂造林生长情况进行调查,结果显示:造林区域内水位、种植点与水岸间距离等对造林树种的生长均有一定的影响。综合分析认为,试验造林树种应选择地下水位50～100 cm的立地为宜,水位太高将造成植株浸水时间过长,植株生长不良。不同树种间受水位、坡度的影响也不同,其中垂柳、水杉、池杉3个树种的平均地径随平均水位下降而增大。
In this paper,the growth condition of 4 afforestation species planted on the Tai Lake beach has been investigated.The results showed that the water level and the distance to water-front have some influence on their growth.Comprehensive analysis results showed that soil thickness of the appropriate planting ranged from 50 to 100 cm,away from the nearby water-level.Being close to the water level line will cause the plant to soak too long and poor growth.In addition,the different water level and slope had different influence on average ground diameters of the afforestation species.The average ground diameters of Salix babylonica L,Metasequoia glyptostroboides and Taxodium ascendens increased with the rise of mean water levels.And the growth had some bearing with different species and planting positions.
