| 摘 要： | 通过对6年生杨树造纸试验林施肥试验结果的分析，发现杨树造纸林压绿肥没能明显地促进林木的生长，也没有明显地起到改良土壤的作用；施化肥（尿素）能够促进林木的生长，并能提高林分的产量，但经济效益呈负增长，建议各地杨树生产单位不要盲目施肥。

| Abstract: | Fertilization experiments were carried out in 6 years Poplar p1antations for papermaking. The results showed that green manuring did not promote tree growth apparently and did not take obvious effect on soil amelioration either. Fertilization(using urea)increased tree growth and the yield, but econo mic benefit was negative growth. It is suggested that poplar preduction units at all levels should not fertil ize blindly. |

| Keywords: | poplar stands for papermaking fertilization benefit |
