| 摘 要： | 为弄清三峡重庆库区柑桔园土壤养分的现状及变异特征，为合理施肥和调控柑桔营养提供依据，以三峡重庆库区柑桔园的土壤养分为研究对象，分析地域、土壤类型对土壤养分变异的影响。结果表明，重庆市柑桔园土壤养分含量比较适宜的有：有效磷、速效钾、有效锌；呈亏缺状态的有：土壤碱解氮、有机质、有效硼；含量严重超标的有：土壤有效铁、有效锰和有效铜。各种植区柑桔园土壤养分肥力总体表现较好的为永川、江津和奉节。土壤类型是影响土壤有效锰含量的重要因子，而对土壤碱解氮、有效磷和有效硼含量影响较小。造成不同土壤类型间土壤养分变异的具体原因还有待于进一步研究。 |

| Abstract: | In order to make clear soil nutrient status and variability characters, provide foundation for rational fertilization and citrus nutrient improvement, soil nutrient in citrus orchard of three gorges was studied, the effect of different areas and soil type on soil variability was analyzed. The result showed that the content of available P, K and Zn in citrus orchard were appropriate; alkaline N, organic matter and available B were deficiency; the content of available Fe, Mn and Cu were beyond the standard wh... |
