摘要
为揭示平欧杂种榛产量与园地土壤养分及树体营养元素含量间的关系,对不同产量园地土壤养分及树体叶片营养元素含量进行了测定分析。结果表明,土壤有效磷含量与园地产量存在显著正相关关系。土壤有机质含量与土壤养分存在显著正相关关系。树体叶片营养元素含量与产量没有显著相关性。园地土壤有效养分与树体叶片营养元素含量没有显著相关性。研究结果为榛子园肥力管理提供理论参考。
To discover the relationship between hazelnut yield and soil nutrition as well as nutrient element of Corylus heterophylla×C.avellane,soil nutrition and leaf nutrient element contents were measured in orchards with different yields.The result indicated that hazelnut yield was obviously positive correlated with soil available phosphate.There was a significantly positive correlation between soil organic matter content and soil nutrients.There was no significant correlation between leaf nutrient content and yield and between available soil nutrients and nutrient element contents in tree leaves.This study would provide theoretical reference for fertility management of hazelnut orchard.
