【目的】探讨湖南省柑橘园果实矿质元素与土壤养分的关系,为指导果园科学施肥提供参考依据。【方法】对湖南省主产区84个柑橘园土壤理化性质和果实矿质元素含量测试分析,运用SPSS、R和LINGO软件多元统计分析筛选出影响果实矿质元素的主要土壤因子,求解土壤养分线性规划方程,指出果园土壤养分缺素问题。【结果】Pearson相关分析结果表明,果实全钾、全钙和全铁含量与土壤pH呈正相关,其余的果实矿质养分与土壤pH均呈负相关;果实全氮、全磷和全钙含量与有机质含量呈负相关,其余养分与有机质含量均呈正相关。典型相关分析表明果实矿质元素与土壤养分因子间存在90.59%的相关性,果实矿质元素受到多个土...

【Objective】84 soil and fruit samples from main citrus producing areas in Hunan province were collected to explore the relationship between soil nutrients, pH and fruit mineral nutrient, in order to provide reference for scientific fertilization in orchards in Hunan province.【Methods】Soil physical and chemical properties affect soil fertility, while tree nutrition reflects soil nutrient utilization efficiency. Understanding factors affecting soil nutrient utilization in citrus orchards is crucial for soil fertilizing and soil modification. W...
