摘要
通过对奈曼八仙筒林场采用不同施肥时间、施肥量、施肥方式及间作等因素对杨树速生丰产林林木生长量影响的试验，利用正交设计分析，选择最佳施肥方案。
A research trial was conducted in ba Xian Tong Forestry Farm,Naiman Banner ofZhelifnu League on the impact of fertilization schedule(timing,dosages,methods of fertiliza-tion and intercropping)on the incremet of a fast- growing and high- yielding poplar standwith lattice design in order to obtain a optifimal fertilization packages.
