| 摘 要： | 作物多元素的营养水平与其产量的相关性研究至今尚未见文献报导。本文提出了多元素营养水平的计算方法:即把各个营养元素的浓度均换算成氮素浓度来表示,并根据各个营养元素对于产量的贡献进行加权,以加权总和来表示多元素的营养水平。回归分析结果表明,椪柑多元素的营养水平与其产量呈正相关,相关系数高度显著(P<0.01)。此外,本文还提出了椪柑的营养断诊标准。

| Abstract: | This article studies the correlation between multielement nutrient levels and the production of crops. Here the case of the fruit pongan ( citrus
reliculata hlan(?) is specifically studied. The findings of a regressive the analysis of levels of its nutrient elements show taht such levels are positively correlated with the production of this crop, and the coeffioient of their correlation is significantly high ( P<0.01 ) . A standard of diagnosing the nutrient of pongan is also proposed. |
