摘要： 为探明幼龄和成龄国红苹果园不同土层土壤中微量元素的动态变化规律,在河北省农林科学院石家庄果树研究所苹果标本实验园内,分别采集了幼龄和成龄国红苹果园0~20,20~40,40~60 cm土层的土壤样品,通过VISTA-MPX等离子光谱仪对国红苹果土壤中5种微量元素进行了含量测定,采用SPSS软件进行多元统计分析和相关性分析。结果表明,整个生长周期内幼龄和成龄国红苹果园土壤硼元素含量均呈波动性起伏变化的动态规律,而铁、锌元素则无明显变化。典型性相关分析表明,0~20 cm土层锰元素之间、锌元素之间均呈显著正相关,20~40 cm土层锌元素之间、硼元素之间呈显著正相关,40~60 cm土层幼龄和成龄各元素之间无相关性。可为指导果园优质栽培和研究不同栽培措施对改善优化国红苹果园土壤中微量元素含量提供科学的理论依据。

Abstract: The objective of this study is to determine the dynamic changes of the major elements in soil between young Guohong apple trees and adult ones.The soil of young and adult Guohong apple trees had been collected in Shijiazhuang Pomology Institute,Hebei Academy of Agriculture and Forestry Sciences,and the content of the five kinds of major elements had been tested by VISTA-MPX plasma spectrometer,and multivariate statistical analysis and correlation analysis had been done by SPSS software.The result showed that during the whole growth period the content of Boron waved between the young trees and adult ones,while the content of Iron,Zinc had no changes significantly.Typical correlation analysis showed that the content of Manganese were significantly positive correlation between elements in 0-20 cm soil layer,Zinc too.while the content of Zinc were significantly positive correlation between elements in 20-40 cm soil layer,Boron too.The five microelements had no correlation in 40-60 cm soil layer.The results provided scientific theoretical basis for guiding the orchard how to cultivate for higher qualities,and for studying how to enhance the content of the microelement by different cultivation measures.
