| 摘 要： | 土壤pH值与有效态养分含量之间有密切的关系.威海市文登梨园土壤pH值为4.06～6.59,极强酸性和强酸性土壤占所调查总样品数的40%.土壤pH值与有效钾、有效铜、交换性钙有极显著正相关性,与有效铁呈极显著负相关性,而与有机质、碱解氮、有效磷、有效锌、有效锰、交换性镁相关性不显著.梨园叶片Cu、Zn、Fe、Mn平均含量均高于适宜值范围,钙在适宜值范围内,镁低于适宜值范围.因此,施用石灰及碱性肥料是提高土壤的pH值,不断培肥土壤和改善梨果实营养的一项有效措施.

| Abstract: | The correlation between soil pH and the contents of available nutrients in selected soil from three orchards in Wendeng was studied.The range of soil pH value was from 4.06 to 6.59;the ratio of highly and strongly acidic soil among samples was 40%.The relationship between pH value and rapidly available kalium,available cuprum,exchangeable calcium was very significantly positive mutuality,but available iron was very prominently negative mutuality.The pH value didn't correlated significantly or very significa... |
