林木计量施肥研究动态

Advances in Research on Theories and Methods of Forest Calculated Fertilization

综述了近百年来林木施肥的研究概况，评述了林木施肥的各种计量方法，并按成熟度和施肥原理将林木计量施肥划分为经验法、肥料效应函数法、林木营养诊断法和配方施肥法4大类型，探讨了我国林木计量施肥存在的问题，并提出了我国未来林木施肥的发展方向是按树种、分立地、分林木生长阶段的目标效益下的计量施肥．

This paper focuses on the major theories and methods of forest calculatedfertilization and makes brief comments on the history of forest fertilization research in therecent 100 years. According to the theories and developments, the methods of forest calculated fertiilization are divided into four types including experimential method, fieldfertilizer experiment, nutrient diagnosis of trees and formulated fertilization. In addition,the paper puts forward the trends of forest fertilization.
