| 摘 要： | 采用DRIS诊断法对四川60块巨桉人工林标准地叶片养分进行诊断,筛选出N、P、Fe、B等4个叶片养分浓度指标和N/Zn、P/N、P/K、P/Ca、P/Zn、P/B、K/N、K/Zn、Ca/N、Ca/Zn、Ca/Mn、Ca/B、Mg/N、Mg/P、Mg/K、Mg/B、S/N、S/Mg、S/Zn、Cu/N、Cu/P、Cu/K、Cu/Mg、Cu/Zn、Cu/B、Zn/Mg、Fe/N、Fe/P、Fe/K、Fe/Ca、Fe/Mg、Fe/S、Fe/Cu、Fe/Zn、Fe/B、Mn/P、Mn/K、B/N、B/K等39个叶片养分浓度比值指标,并利用高产组叶片养分浓度、高产组养分诊断指数及其等级制定了相应的养分诊断标准,为指导生产提供了参考依据.

| Abstract: | Sixty standard sample sites were set up to diagnose foliar nutrient status by DRIS.Four foliar nutrient concentration indexes including N,P,Fe,B and thirty-nine foliar nutrient concentration ratio indexes including N/Zn,P/N,P/K,P/Ca,P/Zn,P/B,K/N,K/Zn,Ca/N,Ca/Zn,Ca/Mn,Ca/B,Mg/N,Mg/P,Mg/K,Mg/B,S/N,S/Mg,S/Zn,Cu/N,Cu/P,Cu/K,Cu/Mg,Cu/Zn,Cu/B,Zn/Mg,Fe/N,Fe/P,Fe/K,Fe/Ca,Fe/Mg,Fe/S,Fe/Cu,Fe/Zn,Fe/B,Mn/P,Mn/K,B/N,B/K were chosen as diagnosis indexes,and corresponding diagnosis standards were established by using foliar nutrient concentration,nutrient diagnosis indexes and grades of high yield group. |
