本研究旨在探明砧木与自根树对椪柑叶片常量元素含量的影响。试验结果表明,苗期和初结果期枳砧(半矮化砧)椪柑与两种桔砧(椪柑、福桔乔化砧)椪柑的叶片常量元素含量存在显著差异;初盛果期积砧椪柑与椪柑自根树叶片常量元素含量亦有一定差异。鉴于积砧椪柑具有早结、高产之特性,且在生产上愈益受到重视,故宜继续探明其营养需求特点及不同年龄时期的营养诊断标准,以供指导施肥之参考。
The purpose of this study was to determine the effect of rootstocks and self-rooted trees on the content of major elements in P. citrus leaves. The results showed that there were significant differences in the leaf element contents between Poncirus trifoliata (semi-dwarfing anvil) and Citrus aurantium (Citrus aurantifolia, Citrus aurantium) There were also some differences in the content of major elements in the leaves of P. armeniacum. Given the characteristics of early rooting and high yield, as well as more and more attention paid in the production, it is suggested that the product should continue to explore the characteristics of its nutritional requirements and the diagnostic criteria of nutrition at different ages for guidance on fertilization.
