| 中文摘要: |
| 从江苏省和贵州省两大越橘主产区各选取两个越橘园，分别为连云港市赣榆区和东海县越橘园、安顺市平坝区和惠水县越橘园，并于2015年7月检测4个越橘园的土壤有效养分和叶片营养含量丰缺状况，并对越橘园土壤与叶片相应营养元素进行相关性分析，为合理制定越橘园施肥方案提供理论依据。结果表明，除平坝越橘园以外的其余越橘园均需要进行土壤pH值和有机质含量调节；4个越橘园土壤有效养分均呈现缺氮富磷富钾状态，土壤交换性钙、镁、有效硫、微量元素含量充足；存在叶片氮、磷、铜含量缺乏，叶片其余营养元素含量适中。通过对土壤与叶片相应营养元素之间的相关性分析得知，土壤中大部分有效养分与其对应的叶片营养元素之间均无显著相关性。因此得出，越橘园在营养管理上应因地制宜，建议增施有机肥及氮肥，合理施用磷、钾肥。 |

| We have selected four blueberry orchards from the two biggest blueberry production area in Jiangsu and Guizhou province. Respectively are from Ganyu and Donghai blueberry orchards in Lianyungang, and Pingba and Huishui blueberry orchards in Guiyang. Both nutrient element contents of soils and leaves were detected in July 2015, and then analyzed their correlation between nutrient element contents of soils and leaves. The aim is to provide the reasonable fertilization plan for the blueberry orchard. The results showed that the pH of soil and organic matter content were only appropriate to Pingba blueberry orchards, all the other blueberry orchards need to adjust soil pH and organic matter content. The four blueberry orchards all appeared lower available nitrogen content and higher available phosphorus, potassium content in soil. Exchangeable calcium, magnesium, available sulfur, and micronutrient in soil were exceeded standard. The nitrogen, phosphorus and copper were lack in blueberry leaves, but the rest of the content of the nutrient element in blueberry leaves were moderate. The result of correlation analysis showed that the correlated for nutrient element contents of soils was nonsignificantly with the contents of the corresponding nutrients in leaves. Therefore, in the nutrition management of blueberry orchard should adjust measure to local conditions, and suggesting application of organic fertilizer and nitrogen fertilizer, and phosphorus, potassium fertilization under reasonable application. |
