| 摘 要： | 采用临界值法对尾叶桉幼林材积生长进行叶片营养诊断，试验结果表明，氮，磷，钾，钙，镁和硼等营养元素的临界浓度分别为15.3g/kg,1.2g/kg,4.2g/kg,16.1g/kg,2.5g/kg和0.019g/kg；最适浓度范围分别为15.3-18.1g/kg,1.2-1.7g/kg,4.2-5.6g/kg,16.1-19.8g/kg,2.5-3.0g/kg和0.019-0.031g/kg，而对树高生长进行营养诊断时，上选结果稍微有些变化，试验还得到各营养元素比值的临界值和最适范围。

| Abstract: | Plant nutrient diagnosis can forecast and evaluate fertilizer effectiveness and assist in adjusting fertilization of plants. Eucalyptus urophylla is a tree species that has many advantages, such as fast growth, resistance to aridity, multiple uses and is widely planted in south China. How to apply fertilizers appropriately for Eucalyptus urophylla is a question in the area. The aim of this study was to compute indices for the nutrients N, P, K, Ca, Mg, B related to the volume of Eucalyptus urophyl... |
