| 摘 要： | 采集攀西杧果主产区果园土壤样本42份,探讨土壤pH值、有效养分状况及两者的相关性。结果表明,攀西杧果园土壤pH值范围为4.8~8.4,中性、酸性土壤占76.2%。果园土壤有机质、碱解氮、交换性钙和有效锌表现为严重缺乏状态,有效铜和硼整体处于低水平,有效钾含量为中下水平,而有效磷、交换性镁、有效硫、有效铁和有效锰5种元素的含量较为丰富。土壤pH值与有机质、碱解氮、有效钾、有效铜、有效锌、有效铁、有效锰呈极显著负相关,与交换性钙、有效硫呈极显著正相关,与有效性磷、有效硼、有效钼的相关性不显著。土壤pH值与有机质符合幂函数,与碱解氮、有效锌、有效硫呈线性相关,与有效钾、交换性钙、有效铜、有效铁、有效锰则符合指数函数,与交换性镁则符合二次函数,各相关系数均达极显著水平。

| Abstract: | 42 soil samples were collected in Panxi mango orchards to evaluate the correlation between soil pH value and available nutrients.Results revealed that the soil pH values of the mango orchards ranged from 4.8 to 8.4,and that the neutral and acidic soils accounted for 76.2%.The contents of soil organic matter,available nitrogen,zinc and exchangeable calcium were extremely low,and the available copper and boron were low.Available potassium was at middle level while available phosphorus,sulfur,iron,manganese an... |
