摘要
本文扼要介绍了林地施肥的概况及其最近有关水肥平衡研究的重要成果。由于林业生产粗放 ,故林地水肥平衡研究尚处于初级阶段。
Researches on water and fertilizer co efficiency of forestry are reviewed briefly,and the important latest achievements about the balance of water and fertilizer are stated. Because forestry production is extensive,applying fertilizer in woodland is at primary stage,only applying fertilizer in forest stand and coordinating between water and fertilizer in woodland are introduced.
