1992～1995年的试验结果表明，在含盐量0.208％的海涂上栽植的11个黑杨无性系中，筛选出5个优良无性系，具有适应性强、生长迅速、效益显著，能抗风、抗盐和抗病虫害，与I-69杨相比，单株材积增长率为4．86％～64．63％，每公顷蓄积增长率为38．38％～74．17％，增加收入7800～15075元／hm2。
The results of the experiment from 1992 to 1995 showed that among the eleven black poplar clones planted on 0.208% salinity of seawater, five excellent clones were screened out, with the advantages of strong adaptability, rapid growth, significant benefits and resistance to wind , Salt tolerance and pest and disease resistance. Compared with I-69, the volume growth rate per plant was 4.86% -64.63%, and the accumulation growth rate per hectare was 38.38% -74.17% and the income was 7800 ~ 15075 yuan / hm2.
