为探究不同母质柑橘园土壤养分特征,阐明土壤母质对肥力影响,为果园精准施肥提供参考依据,本研究采集了5种不同母质的柑橘土壤,共计217个样点,分析了土壤pH、有机质以及大、中、微量元素有效态含量。结果表明:柑橘园土壤平均pH砂岩>第四纪红土>河湖冲沉积物>石灰岩。随着柑橘种植年限延长,板页岩、河湖冲沉积物、石灰岩土壤肥力有极显著提升,第四纪红土肥力有显著提升。综合分析,板页岩发育的土壤养分最为丰富。土壤有机质、碱解氮、速效钾、有效硼、有效磷、有效硫是影响肥力的重要因子,针对不同母质土壤养分间的差异,可因地制宜地对果园土壤进行精准管理,以确保果园的良性发展。

To explore the characteristics of soil nutrients of citrus orchards with different parent materials, clarify the influence of soil parent materials on fertility, and provide theoretical basis for orchard management and precise fertilization, 217 citrus soils with five different parent materials were collected to analyze soil pH, and the contents of organic matter, macro-, medium- and traceelements. The results showed that the mean soil pH value in citrus orchard was less than 5.5, and the soil was acidic. Except for plate shale and limestone, o...
