柑桔营养诊断指标的确定,通常要考虑到植株的产量因素,然而,由于树体营养状况受诸多内外因子的影响,因而也就增加了营养诊断指标与产量之间关系的复杂性。在探讨柑桔叶片元素含量与产量的关系时,研究者基于不同试验条件(包括采 However, the nutritional status of tree is affected by many internal and external factors, thus increasing the complexity of the relationship between nutrition diagnosis index and yield. When discussing the relationship between leaf element content and yield of citrus, the researchers based on different experimental conditions (including mining
