摘要
评述了林木叶片营养诊断中对分析结果解释方面的研究进展。指出了依靠养分浓度评价的局限性,介绍了以养分平衡理论为基础的 DRIS 法,及考虑叶重、叶中养分浓度及含量的诊断方法在林木叶片营养诊断中的应用。
Advance in interpretation of analytic results from foliar nutrient diagno- sis of forest tree was reviewed and limitation of evaluating nutrient status through nu- trient content was pointed out,DRIS method based on nutrient equilibrium theory was introduced,and application of diagnosis method ,which considers leaf weight and nutri- ent,content,in foliar nutrient diagnosis,of forest tree was introduced,too.
