| 摘 要： | 以荷兰3930杨为试材,采用室内沙培试验,研究单独施氮对荷兰3930杨生长的影响,探讨其营养特性。结果表明,施氮量在80~200 mg/L时明显促进苗高、地径生长,最大生长量分别达1.43 m、1.17 cm;施氮量在120~160 mg/L时能明显促进荷兰3930杨总生物量的积累。

| Abstract: | With 3930 Poplaras as test material,the effect of separate nitrogen fertilizer on Helan 3930 poplar seedling growth was studied by indoor sand culture test,and nutritional characteristics of poplar was explored.The results showed that 80-200 mg/L nitrogen concentration could promote seedling height,ground diameter growth,maximum growth were respectively 1.43 m,1.17 cm.120-160 mg/L nitrogen concentration could promote Helan 3930 poplar biomass accumulation. |
