摘　　要：通过对白桦施用不同肥料,测定纤维性状,以期找到纤维原料林最适宜的施肥种类。实验结果表明:施用硫酸钾和尿素的小区白桦样木纤维长度较长,长宽比值较大,较符合纸浆用材林木材标准;施用硫酸钾白桦纤维长度和长宽比性状与其他试验小区样木有显著差异,纤维宽度与长宽比呈极显著的负相关,纤维长度与长宽比呈显著的正相关。本研究施肥仅对纤维长度和宽度性状产生影响。由于林木处于幼龄期,其他相关纤维性状有待进行深入系统研究。Betula platyphylla Suk. were fertilized by different fertilizers,by measuring the fiber Characters,in order to find the optimum fertilization types of fiber raw material forest. The fiber length and ratio of length to width of its fertilizerd by potassium sulfate and urea were better,they were in line with the standards of Pulpwood Plantation wood. Fiber length and ratio of length to width fertilized by potassium sulfate were significantly different from The others. The fiber width and ratio of length to width was significantly negatively correlated,the fiber length and ratio of length to width showed a significant positive correlation. The study was on fertilization effect only on the length and width of fibertraits. As the forest was young,other related fiber traits need to be studied.
