摘要
不同淹水时间滩地 8年生黑杨派南方型无性系胸径、树高生长均存在显著差异 ;随着林龄的增加 ,差异有所减小 ,表明其耐水淹能力随林龄的增加而有所增强。以单株材积、林木保存率为依据 ,划分不同淹水条件滩地的杨树宜林性 ,提出相应的林种规划 。
The marked difference of diameter at breast height and tree height of 8 year old poplars in different time by flood was measured.The results indicated the anti-flood ability increased with the age increase.According to the volume and preserve rate of single-tree,the suitability of poplar in different flood conditions,and the programmer of seedling were pointed out,and the effect on its growth was measured.
