摘要

在刘家峡水库涨落带滩地A

B不同立地条件的地块上

用J172柳

J369柳和青刚柳栽植的护岸林在水库蓄水期间被水完全淹没下仍能存活

其中青刚柳的生长表现最好

在A地的成活率和保存率分别达到97.30%和96.20%;青刚柳的树高、胸径和新稍长分别比J172柳平均提高12.98%

12.50%和10.28%。柳树根系及主干基部长出的大量不定根

可减缓水库水流对滩地土层的冲蚀

以青刚柳1 m×1.5m密度配置的防护效果最好

冲蚀量仅8.64 kg/m2

比对照减少74.38%。坡度小的涨落带滩地更有利于柳树的成活和生长。

Abstract

Salix viminalis was the strongest among all strains of the S.Jiangsuensis planted in the plot A and B in the fluctuation zone of the Liujiaxia Reservoir.In plot A

survival rate and preservation rate were 97.30% and 96.20%

respectively.Compared to the S.Jiangsuensis '172'

tree height

breast diameter and the new branch and tree top increased on average by 12.98%

12.50% and 10.28%

respectively.The underground root systems and the plenty of adventive roots growing on basis trucks can greatly reduce soil erosion by reservoir water.The 1 m×1.5 m allocation density of the Salix viminalis showed the best protection

and sediment yield was 8.64 kg/m2

which decreased 74.38% compared to CK.The fluctuation land with a small slope is suitable for survival and growth of willow.
