| 摘 要： | 为了解早熟梨对N、P、K元素的吸收规律,给合理施肥提供指导,以中梨1号、中梨4号和早酥蜜3个新优早熟梨品种为研究对象,研究果实发育期间,果实、叶片和土壤中N、P、K元素含量的变化规律,并对它们之间N、P、K元素含量的相关性进行分析。结果表明,3个早熟梨品种果实、叶片和土壤中N、P、K元素含量的变化规律基本一致;相关性分析结果相似,3个早熟梨品种土壤与果实和叶片中N、P、K元素含量间均无显著相关性。

| Abstract: | In order to understand absorption regulations of early ripening pear to N,P,K elements,and to provide some references for rational fertilization,using three new superior cultivars of Zhongli No.l,Zhongli No.4,and Zaosumi as study objects,change regulations of N,P and K element contents in fruits,leaves and soils were researched during fruit development period,and correlations of N,P and K element contents among them were analyzed.The results indicated that change regulations of N,P and K elements in fruits,leaves and soils of three cultivars of early ripening pear were basically consistent.The correlation analysis results of the three cultivars were similar,and N,P and K element contents in soils had no significant correlation with fruits and leaves. |
